Problem with JBoss Scheduler. Please help me!!!
Hi.
I have a problem with the JBoss scheduler.
I follow these phases:
1- Create a session bean that implements Schedulable.
2- Implement the method "perform" and put there the code to be executed by Scheduler
3- Create a jboss-service.xml and put this file in a sar file.
Then during of deploy return me this error:
ERROR [Scheduler$Listener] Handling a Scheduler call failed
java.lang.NullPointerException

In method perform i call a business method of an entity bean.
Any ideas to solving this problem?
