[Clustering/JBoss] - Jboss Clustering Performance Issue
by tdakanalis
Hi,
I am interested on some performance issues related with jboss clustering. In particular, I want to ask if the synchronization between the nodes in a jboss cluster occurs in a synchronous or asynchronous way. For example, lets suppose that we have a two node cluster (node1, node2) and a user places a request which is served by the node1. Which of the following options is right: a) The node1 serves the request and then the state of the node2 is updated (asynchronous way), b) the state of the node2 is updated and then the node1 serves the request (synchronous way) .
In addition, I want to ask if there are measurements about the average time is needed for the node synchronization in a Jboss cluster (in a typical environment) and the relation of that time with the average time for serving a users request.
Thanks in advance !!!

[JNDI/Naming/Network] - JBoss / Eclipse RCP: Could not dereference object
by RobertWilson
I have a problem instantiating my remote session bean from my Eclipse RCP client. I get a nest of 3 exceptions:
javax.naming.NamingException: Could not dereference object
Caused by: java.lang.reflect.UndeclaredThrowableException
Caused by: java.land.ClassNotFound: company.service.SessionRemote
Interestingly, this final exception is thrown from the JBoss ClassLoaderUtility. It appears to me that JBoss is overriding Eclipse's ClassLoader, and can't find the relevant class.
This is definetely an Eclipse/JBoss issue - when I run a standalone JUnit test, all the tests pass. When I run it from an Eclipse plug-in test, it fails.
Is this normal behvavious? Can I influence the JBoss classloader at all?
Other key points:
* There is no output on the server (i.e. client-side issue)
* Currently both the client and the JBoss server are running from the same JDK

by csplrj
The XML is not being displayed properly and so the correct XML is
<task-node name="legalDept">
| <task name="task3">
| <assignment class="com.process.jbpm.ActorAssignmentHandler"></assignment>
| </task>
| <event type="task-assign">
| <action class="com.process.jbpm.JbpmActionListener">
| <actionListener>
| com.zycus.contract.authoring.process.ContractStageUpdateEvent1
| </actionListener>
| </action>
| </event>
| <timer name="timer1" transition="LegalApprove" duedate="3 business minutes">
| <script>
| System.out.println("Timer Fired");
| </script>
| </timer>
| <transition to="join2" name="LegalApprove">
| <action class="com.process.jbpm.JbpmPollingActionListener"></action>
| </transition>
| <transition to="join2" name="raiseSomeConcern">
| <action class="com.process.jbpm.JbpmPollingActionListener"></action>
| </transition>
| </task-node>
