Class SimpleSessionHandler

java.lang.Object
  extended byorg.apache.axis.handlers.BasicHandler
      extended byorg.apache.axis.handlers.SimpleSessionHandler
All Implemented Interfaces:
Handler, java.io.Serializable

public class SimpleSessionHandler
extends BasicHandler

This handler uses SOAP headers to do simple session management.

Essentially, you install it on both the request and response chains of your service, on both the client and the server side.

ON THE SERVER:

ON THE CLIENT:

SimpleSessions are "reaped" periodically via a very simplistic mechanism. Each time the handler is invoke()d we check to see if more than reapPeriodicity milliseconds have elapsed since the last reap. If so, we walk the collection of active Sessions, and for each one, if it hasn't been "touched" (i.e. had a getProperty() or setProperty() performed) in longer than its timeout, we remove it from the collection.

Method Detail

invoke

public void invoke(MessageContext context)
            throws AxisFault
Process a MessageContext.

Parameters:
context - the MessageContext to process with this Handler.
Throws:
AxisFault - if the handler encounters an error

doClient

public void doClient(MessageContext context)
              throws AxisFault
Client side of processing.

Throws:
AxisFault

doServer

public void doServer(MessageContext context)
              throws AxisFault
Server side of processing.

Throws:
AxisFault

setReapPeriodicity

public void setReapPeriodicity(long reapTime)
Set the reaper periodicity in SECONDS Convenience method for testing. !!! TODO: Should be able to set this via options on the Handler or perhaps the engine.


setDefaultSessionTimeout

public void setDefaultSessionTimeout(int defaultSessionTimeout)
Set the default session timeout in SECONDS Again, for testing.
