ClassNotFoundException while lookup a Service

[rheydenr02]

Hi all,
I'm using quartz 1.6.3 and JBoss 4.2.2GA (with ejb3). I have deployed an ear file and inside this are some ejbs and servlets. Furthermore, I have a Job scheduled in a quartz service that triggers a method from a servlet. If the job begins to run, it starts the method (which is from a jar file inside the ear). Inside my method I have to lookup an EJB from JNDI. The ejb classes are located in the same ear file. Now, the method is compaining about ClassNotFoundException, because it can't find any class outside the jar which contains the servlet. Perhaps this sounds a little sophisticated, therefore a little example helps. (no code, just pseudocode)

MyServletClass implements Job{
 execute() {
 OtherBean b = lookup(OtherBean);
 b.doSomething();
 }
}

My EAR file contains the following:

MyServletJar.jar (which contains MyServletClass)
MyBeans.jar (which contains the ejbs)
SomeOtherStuff.jar


If I start the execute() method "manually" (i.e. per mbean call from webinterface), it is executed correctly.
It seams, that quartz runs in another classloader and therefore it can't find my other classes from ear. How can I make this work???

TIA,
Ralf.

Am I the the first and only one people of this planet having this problem??? Is anybody out there who can explain me how I can say to the Classloader from JBoss where it can find some classes???

Please post the entire exception stacktrace. And also post the output of the following command:

jar -tf myapp.ear

where myapp.ear is the name of your ear file

Hi jaikiran,
thanks for your reply. Meanwhile, I found the mistake. I haven't activated the quartzservice in jboss-app.xml. Now the Quartz-Service finds all the classes. But - the JBoss server starts the service in multiple threads. But this is another problem which maybe I will handle in another thread.

Greetz,
Ralf.
