Hy,
I am trying to access an EntityManager from JSP scriptlet for testing purposes and it doesn't work.
Here is the JSP scriptlet:
<%
EntityManager em = (EntityManager) (new InitialContext()).lookup("java:comp/env/persistence/em");
Query query = em.createQuery("select u from USER u");
List users = (List) query.getResultList();
for (User user : users) { user.toString(); }
%>
persistence.xml file :
........
<persistence-unit name="myApp">
org.hibernate.ejb.HibernatePersistence
<jta-data-source>java:/XAOracleDS</jta-data-source>
</persistence-unit>
......
web.xml file :
.......
<persistence-context-ref>
<persistence-context-ref-name>persistence/em</persistence-context-ref-name>
<persistence-unit-name>myApp</persistence-unit-name>
</persistence-context-ref>
.......
The application is deployed in JBoss 4.2.2.GA. When I access the JSP page I get the following exception:
javax.servlet.ServletException: javax.naming.NameNotFoundException: persistence not bound
I guess I have to configure the resource in jboss-web.xml too, but I don't know how. I tried with <resource-ref>, but I got the same error.
Any help at all would be highly appreciated !
Thanks.
Andrei
