Using jBPM with EJB, Could you help me?

[hien_2008]

I have created EJB 3 session bean (stateful) and I have this code as below:

1. InitialContext ctx = new InitialContext();
2. JbpmConfiguration cfg = (JbpmConfiguration) ctx.lookup("java:/jbpm/JbpmConfiguration");
3. JbpmContext __ctx = cfg.createJbpmContext();
4. GraphSession session = __ctx.getGraphSession();

I ran this (of course I have jbpm.3.1.sar in deploy folder of jboss server. and JBOSS raised an error at the line 4 with a message (org.jboss.security.SecurityAssociation).

I did not find out the way to fix this. Anyone who has this experience, pls. share me.

(my email: [e-mail])
Thanks

===================

- I am using ehcache-1.1.jar and Hibernate3.1.

Thanks

I assume you did not search other forums or the internet. I found this http://www.jbossgroup.com/index.html?module=bb&op=viewtopic&t=85570

Can you look at it and see if it contains any valuable info?

[hien_2008]

Thanks Ronald,

It's very useful to me and fixed my problem. I just replace ehcache-1.1.jar by using ehcache-1.2.jar and it worked

BTW: Why the servlet environment (I deployed in TOMCAT without EJB context) works well but EJB? what are differences between these environments?
