I am using JBoss 4.04 installed with EJB 3.0 I have an application that I am trying to deploy in an EAR, and in this application I have an MBean that tries to dynamically load a non-EJB class as JBoss is starting up. The MBean basically looks like this: @Service(objectName="jboss.mx:service=ClassPreloadService") | @Management(ClassPreloadManagement.class) | public class ClassPreloadService implements ClassPreloadManagement { | | public void start() throws Exception { | Class.forName("com.example.MyClass"); | } | } However, MyClass uses a third-party jar. If I put this third-party jar in %JBOSS_HOME%/server/default/lib, add the environment variable JBOSS_CLASSPATH to Windows, and set it to be %JBOSS_HOME%/server/default/lib/third-party.jar then I can get the class to load. But I'm pretty sure that this is a hack. I also have third-party.jar in my EAR file, but it can't seem to find it there. Even if I add this line to my application.xml file: <module> | <java> | third-party.jar | </java> | </module> Please, how can I get this class to load at startup without resorting to putting the jar in %JBOSS_HOME%/server/default/lib ? Or is that really the proper way to do it? Thanks for your help! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052584#...
