Connect to MEJB problem

[jxtang]

I modified one of the examples in Administration & Development Manual to connect tom the MEJB in my JBoss server with version 3.0.6. The relevant code snippet is as

InitialContext ic = new InitialContext();
Object ref = ic.lookup( "ejb/mgmt/MEJB" );

ManagementHome home = (ManagementHome)PortableRemoteObject.narrow( ref, ManagementHome.class );
Management mejb = home.create();


However, I got the following exception:

[java] javax.naming.CommunicationException. Root exception is java.lang.ClassNotFoundException: org.jboss.management.mejb.MEJB (no security manager: RMI class loader disabled)

[java] at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:368)

[java] at sun.rmi.server.LoaderHandler.loadClass(LoaderHandler.java:159)

[java] at java.rmi.server.RMIClassLoader$2.loadClass(RMIClassLoader.java:631)

.....

I do not know how security manager play here. Do I miss any jar file in the build.xml? Is there anything needs to be done in the Jboss server configuration? Thanks in advance!

One of the solution is to add the server/default/deploy/ejb-management.jar into the build.xml. As the JNDI lookup operation returns a valid object, it needs certain classes and description files to load the proxy.

Any better solution or comments are welcome.

Hi,

Did you get MEJB to work? May I benefit from your experience?

What I'm trying to do is similar to what you did except
that I need to display in jsp pages. So I tried to put
a java block in a jsp page like below:

InitialContext ic = new InitialContext();
Object ref = ic.lookup( "ejb/mgmt/MEJB" );

ManagementHome home = (ManagementHome)PortableRemoteObject.narrow( ref, ManagementHome.class );
Management mejb = home.create();


but when accessing the jsp page, it complains about
a bunch of ClassNotFoundException. How are running
the example? Which 'Administration & Development Manual' you used?

Thanks.
