I can't figure out how to expose a start service using an XMBean. I started with the
code in the JBoss EJB3 tutorial (XMBeanService.java) and modified it to include:
| public void start() {
| System.out.println("Start was called");
| }
|
Deploying the JAR produced the expected output. I then added the following to the
service-xmbean.xml file:
| <operation>
| <name>start</name>
| <return-type>void</return-type>
| </operation>
|
This produced the following exception:
| java.lang.RuntimeException: Problem registering @Management interface for @Service

Adding a start method to XMBeanServiceRemote.java and deploying the service bean with the
Management annotation @Management(XMBeanServiceRemote.class)
| worked just fine. Am I missing something, or is there perhaps a bug?
