[jboss-dev-forums] [Design of POJO Server] - bean/mbean integration issue

[scott.stark@jboss.org]

I was hoping to be able to reference the jboss-service.xml mbean for the socket remoting transport to register a handler for the ProfileService with it similar to how deployers register with the MainDeployer:


  | ...
  |     <!--
  |         Add a ProfileService handler to the remoting socket connector
  |     -->
  |     <bean name="ProfileServiceInvocationHandler"
  |         class="org.jboss.aspects.remoting.AOPRemotingInvocationHandler">
  |         <install bean="jboss.remoting:service=Connector,transport=socket" method="addInvocationHandler">
  |             <parameter>ProfileService</parameter>
  |             <parameter><this/></parameter>
  |         </install>
  |         <uninstall bean="jboss.remoting:service=Connector,transport=socket" method="removeInvocationHandler">
  |             <parameter>ProfileService</parameter>
  |         </uninstall>
  |     </bean>
  | 

however, there is a type conflict showing up:

To allow for such an interaction, the mbean needs to have a mapping of its ServiceControllerContext to a KernelControllerContext, or ServiceControllerContext and KernelControllerContext need a shared base class that adds a common DispatchJoinPoint notion.

I can workaround this by moving the legacy remoting mbean to a mc bean (hopefully).
