Hi everyone
Today I was download the JBPM 5.4,My boss asked me to use this tool,In one week,perhaps,I should write a demo use JBPM5
6 months ago I was write one demo with jbpm 4.4.But this time,when I check out the Jbpm5's code from website,I think it's change in many points.
now,I request somebody,who can tell me how can I add JBPM5 to S2SH(struts2 Spring3 hibernate 3)?
the key is:
1. in spring config file,which jbpm5 object should be write as a bean
2.how can i start a simple process.(is it like jbpm4?)
3.who can tell me the different between jbpm4 and jbpm5.I refer to the code.
In the end ,I hava to say sorry that my english is not well.
thank you.

Hi, here is my problem, I made an EJB with maven and 2 test clients,
* a test client without maven, only added jnp-client and the EJB to it's class path, work like a charm
* a test client using MAVEN, added the EJB through the POM and jnp-client, does not work
this is my EJB :
[img] http://img11.hostingpics.net/pics/480421EJB1.png http://img11.hostingpics.net/pics/480421EJB1.png[/img]
it's POM :

this is my first test client, the one without maven wich has no problem whatsoever to speak with the EJB
[img] http://img11.hostingpics.net/pics/974963EJB0.png http://img11.hostingpics.net/pics/974963EJB0.png[/img]
this is my second test client, using maven, it cannot speak with the EJB, all I'm getting is :
[code]
Context lookup finished
Exception in thread "main" java.lang.ClassCastException: javax.naming.Reference cannot be cast to com.thongvan.mp.MyFirstMavenEjb.TestMavenEjb

[/code]
Both clients have the same main :
[code]
public static void main( String args[] ) throws NamingException
{
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
Context ctx = new InitialContext(env);
System.out.println("Context lookup finished");
TestMavenEjb proxy = (TestMavenEjb)(ctx.lookup("TestMavenEjbBean/remote-com.thongvan.mp.MyFirstMavenEjb.TestMavenEjb"));
System.out.println(proxy.getClass());
System.out.println("do something!");
proxy.doSomething();
}
[/code]
So, anybody has even the slightest idea about why the maven test client is not working?
Jboss 5.1.0.GA
Eclipse indigo
Maven 3.0.4
Also I did some poking around by printing a toString on both context lookup here is what I got :

[jBPM] - Intermittently pending human task come across a missing jbpm parent process in jBPM 5.2

--------------------------------------------------------------
Env: Jboss 7.1.0, mysql DB, Redhat 5.5, jBPM 5.2
When I thought I'm getting pretty good with jBPM and our application is about to be released, i came across this tough bug during extensive testing.
Intermittently we're facing that pending human task has missing parent process instance and it results in nullpointerexception while completing that human task.
I ran below SQL query to confirm this:
select t.id, t.processInstanceId from Task t where t.processInstanceId not in (select distinct(InstanceId) from ProcessInstanceInfo);
+----+-------------------+
| id | processInstanceId |
+----+-------------------+
| 33 | 20 |
| 43 | 20 |
| 47 | 20 |
| 53 | 20 |
| 57 | 20 |
+----+-------------------+
Same code works fine most of the time. So I think it's not problem with our code but some bug in jBPM. MinaTaskServer is being used for our implementation.
Also we use JTA persistence for jBPM core engine and RESOURCE_LOCAL for human task. We have to use RESOURCE_LOCAL for human task because JTA can't be used due to another jBPM bug.
If I reinitialize the database, then everything works fine for a while but again I run into this problem.
Please let us know how we can fix it, if anyone knows solution. I was about to create a blocker JIRA issue but thought let's first get community opinion on this.
Exception stack trace is attached.

[jBPM] - SignalEvent issue in jBPMConsole
by Herman Post
Herman Post [https://community.jboss.org/people/hbpost] created the discussion
"SignalEvent issue in jBPMConsole"
To view the discussion, visit: https://community.jboss.org/message/757107#757107
--------------------------------------------------------------
We have run into an issue with jbpmConsole that we do not understand. The sample code runs as expected in eclipse but does not run the same in jbpmConsole. (project attached running jBPM 5.3/Drools 5.4)
The sample demonstrates starting two different processes in the same kSession and having one process signal an event in the other process.
The sample code in ProcessApp creates an instance of Hello.bpmn which blocks waiting for a SignalEvent. It then creates an instance of DataDriveProcess.bpmn which has a single action node that calls kcontext.getKnowledgeRuntime().signalEvent("TestSignal", false);
In eclipse this works fine and the Hello process terminates when it receives the SignalEvent from DataDriveProcess.
If these processes are uploaded to Guvnor and packaged, and then started in jbpmConsole, Hello process does not receive the SignalEvent. It can be made to work though, if you start the Hello process, note the processInstanceId, then edit the DataDriveProcess in Guvnor to call signalEvent("TestSignal", false, 8) with the explicit processInstanceId, and rebuild and start DataDriveProcess.
So to summarize, signalEvent in 'broadcast' mode, without a specific processInstanceId does not appear to work in jbpmConsole, but does work in eclipse.
We also tried to iterate through all of the process instances from the Action node in jbpmConsole and just SignalEvent on each, but no other process instances are visible. They are visible in eclipse.
Thanks,
Herm
