Re: [JBoss-user] Startup tasks

don't focus on the beans themselves.  Focus, instead on the MBean deployer that deploys the jar file that contains the beans.  Try to figure out how to make the dependency on that specific deployer.  I'm not 100% sure, but I think a deployer gets instantiated for each jar file that needs deployment.

I have written an MBean, but can't figure out how to get it
to wait until all my Session and Entity Beans have been deployed before
doing the startup activity.

Is there some depends attribute I can put in the jboss-service.xml
file in my .sar?

I tried making JMX calls to the JBoss deployer, but it says
the beans are deployed before they can be looked up by JNDI.

I also tried catching JNDI lookup errors, but there were too
many combinations.  NameNotFoundException, ServerException wrapping
NameNotFoundException, RemoteException wrapping ServerException
wrapping NameNotFoundException.  I abandonded this path, since
it didn't seem I could ever catch all the combinations.

Thanks for any suggestions!

JD

Get the docs and learn to write and deploy an MBean.  Then write an MBean
wrapper around your tftp server and deploy it.  Also the JMX book has an
example of writing an MBean for JBoss.
