    Create exception

    arnaud Newbie

      hi,

      I can't create my EJB 1.1 with JBoss 2.4.1 / Tomcat
      i just have a simple Entity:


      when i call the create method, i still have

      " javax.ejb.CreateException: Could not create entity:java.lang.NullPointerException
      at org.jboss.ejb.plugins.jaws.jdbc.JDBCCreateEntityCommand.execute(JDBCCreateEntityCommand.java:139)"

      i try different create method (with parameters ect..)
      but each time i have the same error.

      My Datasource is ok, and the tables are automatically created by JBoss, so it is "JUST" an entity creation problem,

      please help.
