[JBoss Seam] - Seam remoting and persistence
by tamirw
I'm just starting to play with Seam remoting, and I'm having the following problem with persistence :
My POJO actions are able to query the DB just fine, but when trying to create a new entity instnace, the persist() method seems to return without doing anything in the DB.
I'm attaching the relevant code, persistence.xml and components.xml.
Any help would be greatly appreciated.
persistence.xml
| <persistence-unit name="Iou" transaction-type="JTA">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/IouDatasource</jta-data-source>
| <properties>
| <!--
| <property name="hibernate.hbm2ddl.auto" value="${hibernate.hbm2ddl.auto}"/>
| -->
| <property name="hibernate.hbm2ddl.auto" value="update" />
| <property name="hibernate.show_sql" value="true" />
| <property name="hibernate.transaction.manager_lookup_class"
| value="org.hibernate.transaction.JBossTransactionManagerLookup" />
|
| </properties>
|
| </persistence-unit>
components.xml
| <core:managed-persistence-context auto-create="true"
| entity-manager-factory="#{IouEntityManagerFactory}" name="entityManager"/>
| <core:entity-manager-factory name="IouEntityManagerFactory" persistence-unit-name="Iou"/>

RegisterAction.java

| if (existing.size() == 0) { // the query is executed just fine
| newUser = new User();
| newUser.setEmail(email);
| newUser.setPassword(password);
| newUser.setName(name);
| newUser.setActive(true);
| entityManager.persist(newUser); //nothing is saved to the DB.
| currentUser = newUser;
| return newUser;
| } else {
| User existingUser = (User) existing.get(0);
| if (existingUser.isActive() == false) {
| existingUser.setActive(true);
| log.info("User " + email + " has been activated");
| currentUser = existingUser;
| return existingUser;
| } else {
| log.info("email " + email + " already exists");
| return null;
| }
| }
|
| }
| }
