    EntityManager in AbstractResource throws not mapped exception

    Ranganathan Kaliyur Mannar Newbie

      I have developed a simple and complete seam application. Now, I am attempting to integrate the JasperReports reports into the application. I have developed the reports with EJBQL.
      Now, when integrating them, I use an AbstractResource. In the abstract resource:

      1) Get the EntityManager by

      EntityManager entityManager = (EntityManager)(Component.getInstance("entityManager"));

      2) Use the EntityManager to execute a query like "Select exam from EXAM exam"

      When I run this, I get QuerySyntaxException saying "EXAM is not mapped".

      This Exam component is working fine in the normal part of the Seam application (i.e seam-generated part).
