Hi Rosdi,

I tried your suggestions without much luck. When I create a context
reference to the  Interbase DB the code fails on the following line:

   	DataSource ds = (DataSource) envCtx.lookup("jdbcTranshub");

with the error:

	Name jdbcTranshub is not bound in this Context

The entry I created in the Server.XML file is:

	<Context path="C:\Program Files\Apache Group\Tomcat 4.1\webapps\transhub"
docBase="transhub" debug="0"
                 reloadable="true" crossContext="true">
          <ResourceLink global="jdbc/Transhub" name="jdbcTranshub"
type="javax.sql.DataSource"/>
	</Context>

Java code is:

		Context initCtx = new InitialContext();
		Context envCtx = (Context) initCtx.lookup("java:comp/env");
		DataSource ds = (DataSource) envCtx.lookup("jdbcTranshub");
		Connection conn = ds.getConnection();

Any other ideas?

Thanks in advance, Rob.

PS: I did remove the "Resource-Ref" out of the web.xml file as well.

Robert,

First of all.., I am using Oracle and Tomcat 4.1.9, so my answer might not
apply to your problem..

I got the same error like yours.. but after I removed all reference to the
datasource in web.xml and
then I declared a ResourceLink like this in my server.xml my program is
running perfectly.

Here is my global datasource in server.xml

<Resource auth="Container" name="jdbc/epantaidbPool" scope="Shareable"
type="javax.sql.DataSource"/>
    <ResourceParams name="jdbc/epantaidbPool">
      <parameter>
        <name>username</name>
        <value>epuser</value>
      </parameter>
      <parameter>
        <name>url</name>
        <value>jdbc:oracle:thin:@localhost:1521:epantai</value>
      </parameter>
      <parameter>
        <name>password</name>
        <value>zaq12wsx</value>
      </parameter>
      <parameter>
        <name>maxActive</name>
        <value>20</value>
      </parameter>
      <parameter>
        <name>maxWait</name>
        <value>5000</value>
      </parameter>
      <parameter>
        <name>driverClassName</name>
        <value>oracle.jdbc.driver.OracleDriver</value>
      </parameter>
      <parameter>
        <name>maxIdle</name>
        <value>10</value>
      </parameter>
    </ResourceParams>


And then here is the resource link for my application, also in server.xml.


<Context className="org.apache.catalina.core.StandardContext"
cachingAllowed="true"
charsetMapperClass="org.apache.catalina.util.CharsetMapper" cookies="true"
crossContext="false" debug="0"
docBase="C:\jakarta-tomcat-4.1.9\webapps\mediline_upload"
mapperClass="org.apache.catalina.core.StandardContextMapper"
path="/mediline_upload" privileged="false" reloadable="false"
useNaming="true" wrapperClass="org.apache.catalina.core.StandardWrapper">
          <ResourceLink global="jdbc/epantaidbPool"
name="jdbc/epantaidbPool" type="javax.sql.DataSource"/>
</Context>


Then I create a singleton class to initialise the datasource, all my codes
then get the connection from this singleton class.

I attach the server.xml, web.xml, ConnCache.java, and DatabaseManager.java
for your reference. Hope that helps..

Regards,
Rosdi.

         By default, a non-SSL HTTP/1.1 Connector is established on port =

         * Download and install JSSE 1.0.2 or later, and put the JAR =

         By default, DNS lookups are enabled when a web application =

         "enableLookups" attribute to "false".  When DNS lookups are =
disabled,
         request.getRemoteHost() will return the String version of the
         IP address of the remote client.

                 can be swapped out at any time.

this
                 long (in seconds). If minIdleSwap is higher, then it =
will
                 override this. This isn't exact: it is checked =
periodically.
                 -1 means sessions won't be swapped out for this reason,
                 although they may be swapped out for maxActiveSessions.
                 If set to >=3D 0, guarantees that all sessions found in =

with
       the WebApp Module distribution on how to build it.
       (Or check out the "jakarta-tomcat-connectors/webapp" CVS =
repository)

       To configure the Apache side, you must ensure that you have the
       "ServerName" and "Port" directives defined in "httpd.conf".  =
Then,
       lines like these to the bottom of your "httpd.conf" file:

         LoadModule webapp_module libexec/mod_webapp.so
         WebAppConnection warpConnection warp localhost:8008
         WebAppDeploy examples warpConnection /examples/

       The next time you restart Apache (after restarting Tomcat, if =
needed)
       the connection will be established, and all applications you make
       visible via "WebAppDeploy" directives can be accessed through =
Apache.
