[jboss-user] [JBoss Seam] - entityManager.persist(Object) not working?
Hello all, I have a small question I don't know if the Seam forum is the right place
to post, but I use a seam managed entity manager and it's behaviour puzzles me... A
very simplified sitation sketch:
data class:
| @Entity()
| @Name("data")
| public class Data implements Serializable {
| // field declarations here (plus getters and setters)
| }
|
Bean code:
| @Name("importService")
| @Scope(ScopeType.CONVERSATION)
| public class ImportService implements Serializable {
| @In()
| private EntityManager entityManager;
|
| public void parse(Document d) {
| Data data = new Data();
| // Document d is an XML file, wich is parsed, all values are set in
| // the data object
|
| this.entityManager.persist(data);
| // I hoped the data would be saved by now...
| }
| }
|
Also I have this in components.xml:
| <core:managed-persistence-context name="entityManager"
| auto-create="true"
| persistence-unit-jndi-name="java:/MyEntityManagerFactory"/>
|
And persistence.xml:
| <?xml version="1.0" encoding="UTF-8"?>
| <!-- Persistence deployment descriptor for dev profile -->
| <persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
| http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
| <persistence-unit name="MyDBUnit">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/MyDatasource</jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto"
value="update"/>
| <property name="hibernate.cache.use_query_cache"
value="true"/>
| <property name="hibernate.show_sql" value="true"/>
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:/MyEntityManagerFactory"/>
| </properties>
| </persistence-unit>
| </persistence>

On deploy time, the database table Data is created perfectly, I get all the SQL statements
on my console log. No problem. If I manually insert data, I can query for the data using
this.entityManager.createQuery("from Data data"); even INSIDE the parse method
of the bean, again I see the SQL statement in my console log. But on the
entityManager.persist(data) call, there's no SQL statement executed. I surrounded the
call with a try { ... } catch (Exception e) { ... } block but there are NO exceptions
thrown. Just no data is saved :(
Can someone help me with this please? I really don't understand why data is not
saved...!
