Custom MBean Dependency

[nvenk]

Hi:

Can someone tell me how to best ensure that my custom mbean gets started the last (so that all services are available to it) ?

Essentially, the custom MBean shall be used to reconstruct the last application state on a server restart. The state is rebuilt from persistent data.
The application uses CMP/PostGres.

Thanks very much !!!

Add a dependency on the Deployment Scanner.
Once that is started, the initial state is loaded.

You might want to look at the change notes
click on tracker at www.sf.net/projects/jboss

There is a similar service just been added to jboss4.

Hi:
Thanks for your response. I did try it but it throws the following exception.
However, I did try to declare the MBean in the jboss-service.xml at the very end WITHOUT any tag and it seemed to start fine. But I would still like to know if this is the recommended approach or is there another fail-safe approach ? BTW, I am using JBoss 3.0.4.

Thanks,

I forgot about that.

The scanner dumps undeployed mbeans when it has
finished.

I bet it deployed after it showed the error?
