Subject cvs commit: xml-axis/java/src/org/apache/axis/handlers BasicHandler.java HTTPActionHandler.java Router.java DebugHandler.java EchoHandler.java ErrorHandler.java
Date Thu, 08 Feb 2001 22:08:18 GMT
gdaniels    01/02/08 14:08:17

  Modified:    java/src/org/apache/axis/handlers DebugHandler.java
                        EchoHandler.java ErrorHandler.java
  Added:       java/src/org/apache/axis/handlers BasicHandler.java
                        HTTPActionHandler.java Router.java
  Log:
  Add several new Handlers:
  
  The Router serves to simply find and invoke a service with the name
  found in the MC_TARGET property of the MessageContext.  This guy
  will get used a lot in various contexts.
  
  The HTTPActionHandler is a demonstration of transport-specific Handlers.
  He just takes the value of the SOAPAction property and puts it into the
  MC_TARGET property so that a Router can use it.
  
  BasicHandler is an abstract class to make writing Handlers easier.  It
  encapsulates the property database, and stubs for every method
  except invoke() (which must be implemented by subclasses).
  
  Changed ErrorHandler + EchoHandler + DebugHandler to extend
  BasicHandler.  They're tiny now. :)
