    Hibernate problem using @PersistenceContext

    Debasree Saha Newbie

      Hi,

      I wanted to get data from the jbpmDB(HSQL databse) stored. But when I use the @PersistenceContext I get the exception saying
      1> java.lang.RuntimeException: Could not create Component: searchaction
      2>Caused by: java.lang.IllegalArgumentException: @PersistenceContext may only be used on session bean or message driven bean components: searchaction

      When I remove this then At runtime i get nullpointerexception when clicking the search button which is suppose to get data from database.

      Please suggest what can be the problem.



      THanks in advance.
