    Removal of beans

    Andy Newbie

      I have a servlet-based web app and need to delete an instance of a bean. So i call

      bean_home.remove(primary_key).

      If I create a bean instance using create within the web app, calling bean_home.remove(primary_key) works fine. If however I use an external client to create the bean instances, it fails with

      java.lang.NullPointerException

      at org.jboss.ejb.EntityContainer.remove(EntityContainer.java:507)


      I can do a findByPrimaryKey on the bean instances created by the external client, and can view them, yet get this error when I try to remove them.

      I'm clearly missing something

      TIA
