org.xmlBlaster.test.client
Class TestPersistentSession

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.xmlBlaster.test.client.TestPersistentSession

All Implemented Interfaces:

junit.framework.Test, I_Callback, I_ConnectionStateListener

public class TestPersistentSession
extends junit.framework.TestCase
implements I_ConnectionStateListener, I_Callback

Tests the persistent sessions .
For a description of what this persistent sessions and subscriptions are please read the requirement engine.persistence.session.

This is an interesting example, since it creates a XmlBlaster server instance in the same JVM , but in a separate thread, talking over CORBA with it.

Invoke examples:

   java junit.textui.TestRunner -noloading org.xmlBlaster.test.client.TestPersistentSession
   java junit.swingui.TestRunner -noloading org.xmlBlaster.test.client.TestPersistentSession

Method Detail

setUp

protected void setUp()

Sets up the fixture.

Connect to xmlBlaster and login

Overrides:

setUp in class junit.framework.TestCase

setup

private void setup(boolean restrictedEntries)

tearDown

protected void tearDown()

Tears down the fixture.

cleaning up .... erase() the previous message OID and logout

Overrides:

tearDown in class junit.framework.TestCase

TEST: Construct a message and publish it.

Throws:

TEST:

reachedAlive

public void reachedAlive(ConnectionStateEnum oldState,
                         I_XmlBlasterAccess connection)

This is the callback method invoked from I_XmlBlasterAccess informing the client in an asynchronous mode if the connection was established.

This method is enforced through interface I_ConnectionStateListener

Specified by:

reachedAlive in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedAliveSync

public void reachedAliveSync(ConnectionStateEnum oldState,
                             I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

Invoked when the dispatcher goes to synch again after having delivered entries which where in the queue when the state changed to ALIVE. Note that this could take some time or in the worst case it could never been invoked if the queue is never completely processed.

Specified by:

reachedAliveSync in interface I_ConnectionStateListener

Parameters:

oldState - is always ALIVE.

reachedPolling

public void reachedPolling(ConnectionStateEnum oldState,
                           I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection state has changed to POLLING.

Specified by:

reachedPolling in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

reachedDead

public void reachedDead(ConnectionStateEnum oldState,
                        I_XmlBlasterAccess connection)

Description copied from interface: I_ConnectionStateListener

This is the callback method invoked from XmlBlasterAccess informing the client that the connection was lost (i.e. when the state of the connection has gone to DEAD).

Specified by:

reachedDead in interface I_ConnectionStateListener

Parameters:

oldState - The previous state of the connection.

update

public java.lang.String update(java.lang.String cbSessionId,
                               UpdateKey updateKey,
                               byte[] content,
                               UpdateQos updateQos)
                        throws XmlBlasterException

Description copied from interface: I_Callback

This is the callback method invoked from I_XmlBlasterAccess informing the client in an asynchronous mode about a new message.

So you should implement in your client code the I_Callback interface - suppling the update() method where you can do with the message whatever you want.

The raw protocol driver specific update() method (e.g. CORBA-BlasterCallback.update()) is unpacked and for each arrived message this update is called.

Specified by:

update in interface I_Callback

Parameters:

cbSessionId - The session ID specified by the client which registered the callback. You can specify a cbSessionId during connection (with ConnectQos) and this is bounced back here so you can authenticate the message.

updateKey - The arrived key containing the topic name

content - The arrived message content. This is your payload.

Throws:

XmlBlasterException

                                boolean expectEx)

testOverflow

public void testOverflow()

Tests the requirement: - If the storage for the sessions is overflown, it should throw an exception

Deprecated. Use the TestRunner from the testsuite to run it:

   java -Djava.compiler= junit.textui.TestRunner org.xmlBlaster.test.client.TestPersistentSession

Invoke: java org.xmlBlaster.test.client.TestPersistentSession
