ignored dependency

[goldberg.howard]

boss 5.1 ga
Setting a dependency in my service on an MBean to avoid a race condition.
Setting dependency in my service as follows:

. . .
import org.jboss.beans.metadata.api.annotations.Depends;
import org.jboss.ejb3.annotation.Service;

/**
 * Service implementation class ResILogMgr
 */
@Service
@Depends("jboss.j2ee:ear=jrules-res-management-JBOSS5.ear;jar=res-model-mbean-7.0.0 jar;name=IlrJMXRepository;service=EJB3")
public class ResILogMgr implements ILogMgrRemote, ILogMgrLocal {
. . .

 public void create() throws Exception {
. . .

In the stack trace, no dependency is listed as the service is being processed, and the create method causes an error as it is not waiting for the first service to start. Works fine when the server is warm as the MBean has already been registered. Am I missing something, or is there a bug.

import org.jboss.beans.metadata.api.annotations.Depends;

Wrong import. Should be:

import org.jboss.ejb3.annotation.Depends;

[goldberg.howard]

Thanks for the pickup. Using JBOSS tools plugins--that was the autofill import--I'll post a bug report.

I'm trying to find the dependent MBean. From the stack trace, "RES:type=IlrJMXRepository" is what gets registered in the MBeanServer. Do I set the dependency on this, scanning the JMX-Console, I don't seem to find another entity to set as the dependency.

Yes, that would be the right dependency.

[goldberg.howard]

Hmm--still fails

DEPLOYMENTS IN ERROR:
Deployment "<UNKNOWN jboss.j2ee:ear=IMgrEar.ear,jar=ResILog70Mgr.jar,name=ResILogMgr,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'RES:type=IlrJMXRepository' **

I can successfully retrieve the MBean entry from the MBean registry using the get method through the JMX-console using this objectname.

General question is whether any MBean can participate in dependency relationships, or only certain MBeans, do they have to implement a particular interface to be valid service dependencies.

[jaikiran]

Post your entire console logs (not server.log) and even the updated code. Who registers the RES:type=IlrJMXRepository service?

While posting logs or xml content or code, please remember to wrap it in a code block by using the Code button in the message editor window. Please use the Preview button to ensure that your post is correctly formatted.

[goldberg.howard]

It's a vendor-based JMXBean--turns out, it doesn't implement the JBOSS-specific interfaces to support dependency management. Either I need a JBOSS-specific implementation, or may be remedied with EJB3.1 / @DependsOn as a vendor-neutral standard, although I don't have enough familiarity to know if most app servers support exposing EJB's as JMXBeans.

Thanks,
Howard

[jaikiran]

I might be missing something, but doesn't that vendor specific JMX Bean ultimately get registered in the JBoss MBean server with a specific MBean ObjectName? If it does, then specifying that ObjectName in the @Depends should work.

[goldberg.howard]

The vendor specific JMX Bean doesn't implement or extend org.jboss.system.Service or implement any of the necessary lifecycle methods (per the vendor). Using the ObjectName as indicated below in the @Depends did not work. From the JBOSS documentation, it seems that there are some minimal requirements for MBeans to support the dependency framework. Is that not the case?
