    SSLB's and MBeans

    columod Newbie

      hi all,
      i'm new to JBX so apologies if this question sounds niave.
      I've an application which has a number of stateless session beans running the business logic. I'd like to expose some of the methods on these beans to JMX so that i can manage the beans when they are deployed.
      However, i can' t seem to deploy the mbeans ;-( I've the session beans and mbean interfaces packages into a jar file and this jar file along with the corresponding jboss-service.xml file are packaged into a .sar. When i deploy the .sar i get the following error :

      if i convert the session bean into a plain java file it seems to work fine but this is not ideal as i need the other features of session beans.
      so my question is, is what i'm attempting possible/a good idea or are SSLB's just not mbeanable??

      thanks in advance,
      colum.
