[jboss-user] [JBoss Seam] - Entity not persisting from within a Servlet Filter
I'm attempting to integrate a servlet filter I wrote into a new seam application, and
I can't seem to get it to persist an entity bean. I've created an EntityManager
from an EntityManagerFactory, and can execute queries against it, but it doesn't seem
to persist the data.
I've tried a few combinations - but to no avail.
From my servlet filter:
| public void doFilter(ServletRequest request, ServletResponse response,
| FilterChain chain) throws IOException, ServletException
| {
| ...
| try
| {
| InitialContext ctx = new InitialContext();
| emf = (EntityManagerFactory) ctx.lookup("java:/userDatabase");
| EntityManager em = emf.createEntityManager();
| try
| {
| System.out.println("Attempting ejb query.");
| List existing = em.createQuery("from User").getResultList();
| Iterator ie = existing.iterator();
| while (ie.hasNext())
| {
| ie.next();
| System.out.println("Object Found");
| }
|
| // And the code that doesn't work.
| // User u = new User("tester");
| // em.persist(user);
|
|
| ...
|
And from my persistence.xml file
| ...
| <persistence-unit name="userDatabase">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/Postgres</jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/userDatabase"/>
| </properties>
| </persistence-unit>
| ...
|
And from my web.xml
| ...
| <!-- Persistence Context Ref -->
| <persistence-context-ref>
|
<persistence-context-ref-name>persistence/UserDatabase</persistence-context-ref-name>
| <persistence-unit-name>userDatabase</persistence-unit-name>
| </persistence-context-ref>
| ...
|
The query returns objects - but when I attempt to persist the User entity - nothing
happens. No exceptions, no results, no record in the database.
I'm running JBoss 4.0.5GA, with ejb3, Seam 1.1, connecting to a PostgreSQL 8.1
database.
Anyone have an idea why it will not persist?
