Hi all!
I'm seeing this error also, and don't know how to get over it. I am using JBoss AS 5.1.0.GA with jboss-remoting 2.5.1, and also checked with jboss-remoting.jar 2.5.4.SP3 in client and common/lib folders (not sure if I should replace more JARs)
These are the tests that I have done so far:
1. Nessus scan on port 3873

Don't know if this was solved by the original poster somehow, but if someone has a clue where to keep looking, I'd be much obliged!

[jBPM] - jBpm 5.2 persistence problem - Oracle - Unknown entity: org.drools.persistence.info.SessionInfo

--------------------------------------------------------------
Hi , I am setting up jBpm 5.2 with persistence for the first time and facing a LoT of issues. I am using jpm 5.2 with Spring 3.0 and Hibernate 3.5.6 on jBoss AS 7 server.
We all know that jBoss AS 7 comes with Hibernate 4 as the default hibernate , but I need to use the Hibernate 3 in my project so I installed hibernate 3 as a module in as7 and that is working as expected . I excluded Hibernate 4 with jboss-deployment-structure.xml and added org.jboss.as.jpa.hibernate:3 as a dependency in manifest.mf [refer http://badr-elhouari.blogspot.in/2011/10/how-to-use-hibernate-3-as-jpa-pr... here how I added hibernate:3 as a module in AS7]
That said , I have configured the entire knowledge base and knowledge session in spring so that I dont have to write code for that - Taking tips from drools - integration module and by using drools-grid-impl jar and drools-spring jar.
Drools-grid jar contains a persistence.xml which used in memory DB [h2] so I modified the xml to use oracle and hibernate 3 instead.
Here is my *application context*:

This is driving me nuts as I have all the required jars in my classPath. Please help !!!

[jBPM] - signal event doesn't work from REST API
by Rudi Fisher
Rudi Fisher [https://community.jboss.org/people/rudi_fisher] created the discussion
"signal event doesn't work from REST API"
To view the discussion, visit: https://community.jboss.org/message/649256#649256
--------------------------------------------------------------
I want to use REST API to call signal. There is some implementation in ProcessMgmtFacade of gwt-console-server for this. I see the source code and I finelly found this in CommandDelegate of jbpm-gwt-core:
public void signalExecution(String executionId, String signal) {
ksession.getProcessInstance(new Long(executionId)).signalEvent("signal", signal);
}
This doesn't fulfil my requirements so I made changes to this class recompile and redeploy. This step is OK, because I made some other changes about this REST API (start process with params) and everythings work fins, so I think the problem is not in this my changed implementation of CommandDelegate. New implementation is:
public void signalExecution(String executionId, String eventType, String eventValue) {
ksession.getProcessInstance(new Long(executionId)).signalEvent(eventType, eventValue);
}
I took example of signal event from original examples to be sure that process is designed OK. I took BPMN2-EventBasedSplit.bpmn2. I tested in Eclipse and works fine - after signal call, process cointinued and finally finished. I deployed this process into my Guvnor repo and started by GWT console. Process stopped and waits at signal nodes (see attached picture).
https://community.jboss.org/servlet/JiveServlet/showImage/2-649256-17846/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-649256-17...
At this point I wanted to push process by send signal event by REST API with new implementation. Method signalExecution in CommandDelegate is called OK and this method take correct process instance (I have log line there to see process instance). But it seems signalEvent on process instance doesn't work. I'm using the same parameters for signal event in Eclipse and in CommandDelegate. I'm confused about what is different between execution in unit test in Eclipse and at server. I made many tests and examples but my probem has no solution to this day. I found some discussion about similar issues but this not solve this problem.
Working unit test in Eclipse
public static final void main(String[] args) throws Exception {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
ProcessInstance processInstance = ksession.startProcess("com.sample.test");
System.out.println("process instance:" + processInstance.getState());
ksession.signalEvent("Yes", "YesValue", processInstance.getId());
System.out.println("process instance:" + ksession.getProcessInstance(processInstance.getId()));
// NO
processInstance = ksession.startProcess("com.sample.test");
System.out.println("process instance:" + processInstance.getState());
//ksession = restoreSession(ksession, true);
ksession.signalEvent("No", "NoValue", processInstance.getId());
System.out.println("process instance:" + ksession.getProcessInstance(processInstance.getId()));
}
private static KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("BPMN2-EventBasedSplit.bpmn2"), ResourceType.BPMN2);
return kbuilder.newKnowledgeBase();
}
Not working code in CommandDelegate and calling at GWT server
ksession.getProcessInstance(new Long(executionId)).signalEvent("Yes", "YesValue");
For BPMN2-EventBasedSplit.bpmn2 see official examples in version 5.2.0 Final
