I have an applet client that is calling a session bean, which in turns accesses the entity bean (JBoss 3.2.7/EJB 1.1/JDK 1.5).

I get an ObjectNotFoundException when trying to get the entity bean with the findByPrimaryKey method. The row of data is in the database and the bean has been deployed successfully.

I've recently migrated this from JBoss-2.2.2_Tomcat-3.2.2, so there may be an additional setting that is needed.

Does anyone know why this might be happening when the data is present in the database?
