[JBoss jBPM] - org.hibernate.StaleObjectStateException: jbpm and esb
by sshetty
Hi,
We see the following invocation when we use JBPM to orchestrate our ESB services.

Here is our env:

| Oracle 10g
| jboss-4.2.3.GA

| jbossesb-4.4.GA

Our BPM does not use fork or joins.
Any help appreciated.
Thanks

[jbpm-users]Newbie question: testing a process without going through wsdl?
by sol myr
Hi,
I'm new to jbpm, and would appreciate help on the following.
I have a simple BPEL process that doesn't require any special container resources (database connection pools, etc). I'ts just a silly "sayHello" BPEL <process>:
- The <receive> expects to receive a person's name
- The <reply> is calculated by: concat('Hello to you ', personsName)
Now, I'd like to test this process.
Tutorials show how to test it as a web-service: deploy to JBoss, get the generated WSDL, generate a client from WSDL, and use this client for testing.
However, my question is: does jbpm provide easier API, that would allow me to test the process as stand-alone, without starting up a server and generating clients?
In other words, I just want the stand-alone piece that knows how to parse <process> files and execute them... without the remoting/soap overhead.
I was hoping for some API in the lines of:
// this is not real code, just 'wishful thinking':
public static void main(...) {
Process p=parseXml(myBpelFile);
p.runOperation("sayHello", "John"); // operation name + input
String reply= p.getReply();
}
Thanks :)
