java.lang.NoClassDefFoundError: org/jboss/system/ServiceMBea

[w4w]

I'm using jboss-4.0.0DR1_tomcat-4.1.24 version and I followed the steps from SUN's web site to make my first Stateless Session Bean.

http://developer.java.sun.com/developer/onlineTraining/Beans/EJBTutorial/TOC.html

After making the apropiate changes to get my Code run, I'm getting following exception when I execute the client side.

It's obvious that ServiceMBeanSupport class is not found. Although I would like to know in what library it is supposed to be, the only similar class I could find was in the jboss-all-client.jar, but the name is ServiceMBeanSupportMBean, is this a typo?

DR1 is a developer's release, I recommend you use 3.2.1 if you're learning EJB.

> DR1 is a developer's release, I recommend you use > 3.2.1 if you're learning EJB.

This is still an issue though. I am having the same problem. Any ideas as to what the problem is?

Thanks.

Found out that this class is located in the jboss-system.jar. But after you that, you will get a java.lang.NoClassDefFoundError: javax/management/NotificationBroadcasterSupport exception.

This happens when simply trying to lookup the home interface of a Session Bean.

Ideas/suggestions appreciated...

[bwmcadams]

I'm having the EXACT same problem, exact same circumstances.

Want to play with the new Timers for a project i'm working on, and no dice.

Lookup on the Home just completely chokes on NoClassDef for org.jboss.system.ServiceMBeanSupport.

It's occurring within the Bean itself as far as I can tell...

Any thoughts?

[geejee]

Just in case you have not discoverred this yourself. The class is located in jboss-jmx.jar

[mortena]

I think I'm having the same problem, but my problem arises when I try to make a Dynamic Proxy copy of a local Object and returns it to tomcat.

That is if I return a Collection of Dynamic Proxy Copies to Tomcat, then the following error arises:
java.lang.NoClassDefFoundError: org/jboss/system/Service

If I change the copies with simple Strings, then no error is produced so the problem seems to have something to do with Dynamic Proxies.

[kasee]

hi,

Reason for this error is you have forgot to add the jar files which are under lib folder of JBoss. Add the jar files of lib folder to the classpath will solve this issue.

I have experienced the same & now it works.

[sradford]

I'm getting a similar/same problem with a remote JNDI lookup (http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= - and it's not due to not including the jars.

[sradford]

I've sorted my problem... take a look at the thread to see how (http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= question is: Why do we now need to include non-client jars? (or shouldn't the non-client ones be moved into the client directory too - and the classes added to jboss-all-client.jar)
