So we currently have an MBean that takes care of the registry lifecycle by building it, putting it on a static holder and firing a "startup event" on it so services that need to do something can.
Later when the MBean is stopped/undeployed, it also sends the appropriate event to the registry (and its contained services).
This way we have the advantage of using the MBean class loader to get all hivemodule descriptors, with the servlet filter approach you need to get in the war class loader all descriptors even if the webapp will never need to have that modules on its classpath.
For the "static holder" we made a class with the same interface as org.apache.hivemind.Registry but with all the methods being static and delegating its execution to a static field that contains the real registry, it also has the needed lifecycle event firing methods to be invoked from the MBean.

There is a servlet filter (http://jakarta.apache.org/hivemind/filter.html) built into the HiveMind framework that will put a HiveMind registry (the "default registry") on each servlet request as it comes in. Then, your servlets can use the HiveMind-managed services by looking them up in the registry... // Inside your servlet... Registry registry = HiveMindFilter.getRegistry( request ); MyService svc = ( MyService )registry.getService( MyService.class ); svc.someServiceMethod( someParameter ); -----Original Message----- From: Jian Wu [mailto:[EMAIL PROTECTED] Sent: Thursday, September 02, 2004 9:19 PM To: [email protected] Subject: Thoughts on how to put Hivemind inside a J2EE Container or Web Container? Hi, Usually, J2EE/Web Container will instantiate EJB/Servlet Object for you. Now, Hivemind will also instantiate these service object. To integrate these two together, I can think that Hivemind is invoked through ServletContextListener to set up the basic services before Servlet get instantiated. Any suggestion or best practice? Thanks a lot!
