Subject Re: Where can I learn about GBeans
Date Wed, 16 Jun 2004 16:58:53 GMT
The best example that I know of is org.openejb.server.ServiceDaemon and 
org.openejb.server.EjbServer.  BTW these classes are just a quick hack 
David Blevins and I put in and are scheduled to be removed, but they 
are great examples of a simple GBean.

Also Alan is correct, if you are getting into JMX stuff, you have 
either gone to far, or there is a bug in the GBEan code.
