  Index: tags-doc.txt
  ===================================================================
  Initial documnetation of the tags
  
  tags existing are:
    useContext
    useDirContext
    list
    lookup
    search
    getAttribute
    forEachAttribute
  
  useContext
  This tag creates an instance of a javax.naming.Context based on the values
  of the attributes providing some of the standard values.  In addition to the 
  System properties and the jndi.properties, some standard properties are 
  scanned in the pageContext attributes.  (note: should this be extended to the
  servlet init params as well?)
  (note: as of right now this does not look into the id and scope to see if the 
  context already exists, so it does not behave entirely like useBean)
  Attributes:
    - envRef (optional)
      This is the name of an attribute that will be searched for that provides
      additional environment information.  This info is subordnate to the info
      provuded by the attributes to this tag
    - env (optional, runtime of type java.util.Hashtable)
      Same as envRef, except that the value is the hashtable
    - url (this or one of providerUrl or intialFactory required,
           runtime of type String)
      If provided, the context created by the other attributges is used to
      create a context in which the parameter of this attribute is used to
      preform a lookup(String) operation.  The context returned from the lookup
      will be the context returned by the tag.
    - providerUrl (this or one of url or initialFactory required,
                   runtime of type java.lang.String)    
      Provides the value of the Context.PROVIDER_URL attribute to the 
      InitialContext environment Hashtable.
    - initialFactory (this or one of url or providerUrl required,
                      runtime of type java.lang.String)    
      Provides the value of the Context.INITIAL_CONTEXT_FACTORY attribute to 
      the InitialContext environment Hashtable.
    - dnsUrl (optional, runtime of type java.lang.String)    
      Provides the value of the Context.DNS_URL attribute to the 
      InitialContext environment Hashtable.
    - authoritatibe (optional, runtime of type java.lang.String)    
      Provides the value of the Context.AUTHORITATIVE attribute to the 
      InitialContext environment Hashtable.
    - batchsize (optional, runtime of type java.lang.String)    
      Provides the value of the Context.BATCHSIZE attribute to the 
      InitialContext environment Hashtable.
    - objectFactories (optional, runtime of type java.lang.String)    
      Provides the value of the Context.OBJECT_FACTORIES attribute to 
      the InitialContext environment Hashtable.
    - stateFactories (optional, runtime of type java.lang.String)    
      Provides the value of the Context.STATE_FACTORIES attribute to 
      the InitialContext environment Hashtable.
    - urlPkgPrefixes (optional, runtime of type java.lang.String)    
      Provides the value of the Context.URL_PKG_PREFIXES attribute to 
      the InitialContext environment Hashtable.
    - id (required)
      The name that the context is to be exported as.  
      (A potential future relaxation may make this optional, but it will only
      be available to body content enclosed that asks for an implicit context)
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
  
  useDirContext
      This behaves exactly like useContext except that the object exported
      will be of type javax.naming.directory.DirContext and the 
      InitialDirContext will be used to generate the contexts.
      
  
  list
    This tag itterates through the list returned by Context.list() and
    the body content is evaluated for each itteration.
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - name (optional, runtime of type String)
      The name to preform the list against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to list against.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - bindings (optional, runtime of type boolean)
      wether or not bound objects are returned
    - nameId (optional, runtime of type String)
      The attribute name of the name listing to be exported
    - nameScope (optional, runtime of type String)
      The scope that the name object will be exported to (page is the default)
    - classId (optional, runtime of type String)
      The attribute name of the class name to be exported
    - classScope (optional, runtime of type String)
      The scope that the class name will be exported to (page is the default)
    - objId (optional, runtime of type String)
      The attribute name of the bound object listing to be exported
    - objScope (optional, runtime of type String)
      The scope that the bound object will be exported to (page is the default)
  
  lookup
    This looks up a particular object and exports it.
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - id (optional)
      Attribute name of the object to be exported
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - name (optional, runtime of type String)
      The name to preform the lookup against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to lookup.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - type (optional)
      The class to cast the looked up object to.  Right now failure to
      cast results in a null return.  The default is java.lang.Object.
      This also determines the type of the exposed scripting variable.
      [Adding an attribute failure with string values null, exception, or 
       classcast to return null, throw a JSPExceptionm or to re-throw the 
       class-cast is a thought.]
  
  search
    Performs a search against a DirContext according to the semantics
    of the search(Name name, String filter, SearchControls cons) in
    javax.naming.directory.DirContext.  The scripting variable 
    - id (required)
      Attribute name of the SearchResult  to be exported
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - name (optional, runtime of type String)
      The name to preform the lookup against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to lookup.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - filter (optional, runtime of type String)
      The LDAP-style search filter to use
    - countLimit (option)
      the maximum number of entries to return.  Default is 0 which _should_ 
      mean return all entries found (but behavior has been observerved in some
      provider/server combinations to mean none).
    - derefLink (optional, runtime of type boolean)
      Determines whether links will be dereferenced during the search.
      default is false
    - attributes (optional, runtime of type String)
      A (generally) comma seperated list of attributes to return in the 
      search results.  Default is null which means return all.
    - attributesSeparator (optional, runtime of type String)
      If comma seperated attributes won't do, provides an alternate 
      delimiter string for the attributes attribute.  Default is ","
    - bindings (optional, runtime of type boolean)
      wether or not to return bound objects.  Default is false
    - searchScope (optional, runtime of type String)
      What scope the search is to be preformed against.  One of subtree, 
      subtree_scope, onelevel, onelevel_scope, object, object_scope.  (The
      <foo> variants are treated as the the <foo>_scope variants).
    - timeLimit (optional, runtime of type int)
      The time limit in ms to wait.  0 means wait indefinatly.
  
  
  getAttribute
    This is a flexible tag to get an attribute.  The specified object can be
    a DirContext, SearchResult, Attributes, or an Attribute.  If the object is
    a DirContext an Attributes object is retrieved with just the requested
    attribute, and then futhter processed.  If it is a SearchResult then the
    return of getAttributes is processed further.  For any Attributes object 
    passed in explicitly or derived the get(attribute) method is executed and 
    stored as the attribute.  
    The contents of the attribute are processed in one of three ways depending 
    on the value of the multivalue tag attribute.  If the value is 'one' then 
    the value returned by Attribute.get() is written to the output stream and 
    the body is skipped.  For 'separator' then the body of the tag servers as a 
    separator for the attribute values in the event of multivalue attributes,
    but it is skipped in the event of a singlely valued or non-existant 
    attribute, and the value of the attribute is explicitly written to the
    appropriate output stream.  And for the case of 'itterate' the the 
    contents of the body are itterated over for each value of the attribute, 
    whether singlely valued of multi-valued (and skipped for a non-existant 
    attribute).  In all cases the attribute is exported to the id and scope
    if provided at the beginning of the tag, so it is available both within the
    tag and after it's execution.
    
    - id (optional)
      Page Context attribute name of the actual Attribute value to be exported.  
      For multivalued attributes where the multivalue mode is 'separator' no 
      attribue is exported, while for the value of 'itterator' it is the current
      value inside the body content or the final value outside the tag.  For 
      'one' it is the only value of the attribute.
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - ref (optional, runtime of type String)
      A refrence to a PageContext attribute to be searched for to use as the
      object to preform attribute operations against.
    - object (optional, runtime of type Object)
      A literal instance of an object to have the attribute operations
      applied against.  An invalid object type will result in the body content
      being skipped an no output being written to the output stream.
    - attribute (optional, runtime of type String)
      The name of the attribute to use for objects of type DirContext, 
      SearchResult and Attributes.  Ignored for object of type Attribute.
    - attribute (optional, runtime of type String)
      one of 'one', 'separator', or 'itterate'.  Se tag description for details.
      
  forEachAttribute
    This tag allows you to itterate through all of the attribute names returned
    for a DirContext, SearchResult, or an Attributes object.
    - id (optional)
      Page Context attribute name of the actual Attribute to be exported.  
      This is the name exposed within the tag Body and after.  It is the 
      Attribute object and not the value of the attribute.
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - ref (optional, runtime of type String)
      A refrence to a PageContext attribute to be searched for to use as the
      object to preform attribute operations against.  Valid types are 
      DirContext, SearchResults, and Attributes.
    - object (optional, runtime of type Object)
      A literal instance of an object to have the attribute operations
      applied against.  An invalid object type will result in the body content
      being skipped an no output being written to the output stream.  Valid 
      types are DirContext, SearchResults, and Attributes.
  
  
  That's all folks!

  Index: todo.txt
  ===================================================================
  known issue
    * Whithout custom coding by someone already knowing JNDI only 
      anonymous access to the various forms of Contexts perfoemed.
  
  potential tags to do ...
    getName
    getClass
    getObject
    getDistinguishedName
    composeName
    MakeEnv
    addEnv
    removeEnv
    write/update/remove tags for Contexts and DirContexts and attributes
  
  Need to decide/figure out how to handle the SECURITY_<FOO> attributes with 
  use[Dir]Context in an integrated J2EE environment with web-application
  authentication (kind of a sinlge sign on solution).
  
  potential features:
   *  make some tags not require 'id', thest tags that look to parent tags
      to provide the needed object
      - addEnv to MakeEnv
      - addEnv to use[Dir]Context
      - anything with a context/contextRef in use[Dir]Context, but it must
        occur after any addEnv tag
   * make attributes of the style fooParam and fooRefParam.  fooParam will 
     get the value of foo from a request param.  fooRefParam will get an
     object from a scoped attribute, but the ref name comes from the ref
     parameter
   * make use[Dir]Context look into the scoped attributes if id is present 
     before making a new tag (i.e. behave more like jsp:useBean)
   * make a set of examples that use no scripting elements, just actions
     and directives.  Possibly will require struts.

  <html><head><title>Preliminary JNDI docs</title></head><body>
  This is just the same thing as tags-doc.txt in the root.  Lame, but functional.
  <pre>
  
  Initial documnetation of the tags
  
  tags existing are:
    useContext
    useDirContext
    list
    lookup
    search
    getAttribute
    forEachAttribute
  
  useContext
  This tag creates an instance of a javax.naming.Context based on the values
  of the attributes providing some of the standard values.  In addition to the 
  System properties and the jndi.properties, some standard properties are 
  scanned in the pageContext attributes.  (note: should this be extended to the
  servlet init params as well?)
  (note: as of right now this does not look into the id and scope to see if the 
  context already exists, so it does not behave entirely like useBean)
  Attributes:
    - envRef (optional)
      This is the name of an attribute that will be searched for that provides
      additional environment information.  This info is subordnate to the info
      provuded by the attributes to this tag
    - env (optional, runtime of type java.util.Hashtable)
      Same as envRef, except that the value is the hashtable
    - url (this or one of providerUrl or intialFactory required,
           runtime of type String)
      If provided, the context created by the other attributges is used to
      create a context in which the parameter of this attribute is used to
      preform a lookup(String) operation.  The context returned from the lookup
      will be the context returned by the tag.
    - providerUrl (this or one of url or initialFactory required,
                   runtime of type java.lang.String)    
      Provides the value of the Context.PROVIDER_URL attribute to the 
      InitialContext environment Hashtable.
    - initialFactory (this or one of url or providerUrl required,
                      runtime of type java.lang.String)    
      Provides the value of the Context.INITIAL_CONTEXT_FACTORY attribute to 
      the InitialContext environment Hashtable.
    - dnsUrl (optional, runtime of type java.lang.String)    
      Provides the value of the Context.DNS_URL attribute to the 
      InitialContext environment Hashtable.
    - authoritatibe (optional, runtime of type java.lang.String)    
      Provides the value of the Context.AUTHORITATIVE attribute to the 
      InitialContext environment Hashtable.
    - batchsize (optional, runtime of type java.lang.String)    
      Provides the value of the Context.BATCHSIZE attribute to the 
      InitialContext environment Hashtable.
    - objectFactories (optional, runtime of type java.lang.String)    
      Provides the value of the Context.OBJECT_FACTORIES attribute to 
      the InitialContext environment Hashtable.
    - stateFactories (optional, runtime of type java.lang.String)    
      Provides the value of the Context.STATE_FACTORIES attribute to 
      the InitialContext environment Hashtable.
    - urlPkgPrefixes (optional, runtime of type java.lang.String)    
      Provides the value of the Context.URL_PKG_PREFIXES attribute to 
      the InitialContext environment Hashtable.
    - id (required)
      The name that the context is to be exported as.  
      (A potential future relaxation may make this optional, but it will only
      be available to body content enclosed that asks for an implicit context)
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
  
  useDirContext
      This behaves exactly like useContext except that the object exported
      will be of type javax.naming.directory.DirContext and the 
      InitialDirContext will be used to generate the contexts.
      
  
  list
    This tag itterates through the list returned by Context.list() and
    the body content is evaluated for each itteration.
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - name (optional, runtime of type String)
      The name to preform the list against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to list against.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - bindings (optional, runtime of type boolean)
      wether or not bound objects are returned
    - nameId (optional, runtime of type String)
      The attribute name of the name listing to be exported
    - nameScope (optional, runtime of type String)
      The scope that the name object will be exported to (page is the default)
    - classId (optional, runtime of type String)
      The attribute name of the class name to be exported
    - classScope (optional, runtime of type String)
      The scope that the class name will be exported to (page is the default)
    - objId (optional, runtime of type String)
      The attribute name of the bound object listing to be exported
    - objScope (optional, runtime of type String)
      The scope that the bound object will be exported to (page is the default)
  
  lookup
    This looks up a particular object and exports it.
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - id (optional)
      Attribute name of the object to be exported
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - name (optional, runtime of type String)
      The name to preform the lookup against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to lookup.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - type (optional)
      The class to cast the looked up object to.  Right now failure to
      cast results in a null return.  The default is java.lang.Object.
      This also determines the type of the exposed scripting variable.
      [Adding an attribute failure with string values null, exception, or 
       classcast to return null, throw a JSPExceptionm or to re-throw the 
       class-cast is a thought.]
  
  search
    Performs a search against a DirContext according to the semantics
    of the search(Name name, String filter, SearchControls cons) in
    javax.naming.directory.DirContext.  The scripting variable 
    - id (required)
      Attribute name of the SearchResult  to be exported
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - contextRef (this or context required, runtime of type String)
      Attribute name that will be searched for to provide the context.
    - Context (this or contextRef required, runtime of type javax.naming.Context)
      A literal instance of a context to be used.
    - name (optional, runtime of type String)
      The name to preform the lookup against.
    - nameObj (optional, runtime of type javax.naming.Name)
      Like name, a literal Name object to use to lookup.  If both this
      and name are specified and the value is not null, this attribute is 
      the one used.
    - filter (optional, runtime of type String)
      The LDAP-style search filter to use
    - countLimit (option)
      the maximum number of entries to return.  Default is 0 which _should_ 
      mean return all entries found (but behavior has been observerved in some
      provider/server combinations to mean none).
    - derefLink (optional, runtime of type boolean)
      Determines whether links will be dereferenced during the search.
      default is false
    - attributes (optional, runtime of type String)
      A (generally) comma seperated list of attributes to return in the 
      search results.  Default is null which means return all.
    - attributesSeparator (optional, runtime of type String)
      If comma seperated attributes won't do, provides an alternate 
      delimiter string for the attributes attribute.  Default is ","
    - bindings (optional, runtime of type boolean)
      wether or not to return bound objects.  Default is false
    - searchScope (optional, runtime of type String)
      What scope the search is to be preformed against.  One of subtree, 
      subtree_scope, onelevel, onelevel_scope, object, object_scope.  (The
      <foo> variants are treated as the the <foo>_scope variants).
    - timeLimit (optional, runtime of type int)
      The time limit in ms to wait.  0 means wait indefinatly.
  
  
  getAttribute
    This is a flexible tag to get an attribute.  The specified object can be
    a DirContext, SearchResult, Attributes, or an Attribute.  If the object is
    a DirContext an Attributes object is retrieved with just the requested
    attribute, and then futhter processed.  If it is a SearchResult then the
    return of getAttributes is processed further.  For any Attributes object 
    passed in explicitly or derived the get(attribute) method is executed and 
    stored as the attribute.  
    The contents of the attribute are processed in one of three ways depending 
    on the value of the multivalue tag attribute.  If the value is 'one' then 
    the value returned by Attribute.get() is written to the output stream and 
    the body is skipped.  For 'separator' then the body of the tag servers as a 
    separator for the attribute values in the event of multivalue attributes,
    but it is skipped in the event of a singlely valued or non-existant 
    attribute, and the value of the attribute is explicitly written to the
    appropriate output stream.  And for the case of 'itterate' the the 
    contents of the body are itterated over for each value of the attribute, 
    whether singlely valued of multi-valued (and skipped for a non-existant 
    attribute).  In all cases the attribute is exported to the id and scope
    if provided at the beginning of the tag, so it is available both within the
    tag and after it's execution.
    
    - id (optional)
      Page Context attribute name of the actual Attribute value to be exported.  
      For multivalued attributes where the multivalue mode is 'separator' no 
      attribue is exported, while for the value of 'itterator' it is the current
      value inside the body content or the final value outside the tag.  For 
      'one' it is the only value of the attribute.
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - ref (optional, runtime of type String)
      A refrence to a PageContext attribute to be searched for to use as the
      object to preform attribute operations against.
    - object (optional, runtime of type Object)
      A literal instance of an object to have the attribute operations
      applied against.  An invalid object type will result in the body content
      being skipped an no output being written to the output stream.
    - attribute (optional, runtime of type String)
      The name of the attribute to use for objects of type DirContext, 
      SearchResult and Attributes.  Ignored for object of type Attribute.
    - attribute (optional, runtime of type String)
      one of 'one', 'separator', or 'itterate'.  Se tag description for details.
      
  forEachAttribute
    This tag allows you to itterate through all of the attribute names returned
    for a DirContext, SearchResult, or an Attributes object.
    - id (optional)
      Page Context attribute name of the actual Attribute to be exported.  
      This is the name exposed within the tag Body and after.  It is the 
      Attribute object and not the value of the attribute.
    - scope (optional)
      The scope the object is to be exported as.  Default is 'page'.
      Follows the JSP spec conventions
    - ref (optional, runtime of type String)
      A refrence to a PageContext attribute to be searched for to use as the
      object to preform attribute operations against.  Valid types are 
      DirContext, SearchResults, and Attributes.
    - object (optional, runtime of type Object)
      A literal instance of an object to have the attribute operations
      applied against.  An invalid object type will result in the body content
      being skipped an no output being written to the output stream.  Valid 
      types are DirContext, SearchResults, and Attributes.
  
  
  That's all folks!
