Hi,
I've a problem with EntityManager configuration on my Seam project,because when
i use the Entity manager components, Jboss retrive an EntityMangaer not bound
exception.
My persistence.xml file is:
| <persistence-unit name="DAPem">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>java:/MysqlDS</jta-data-source>
| <property name="hibernate.show_sql" value="true" />
| <!-- These are the default for JBoss EJB3, but not for HEM: -->
| <property name="hibernate.cache.provider_class"
| value="org.hibernate.cache.HashtableCacheProvider" />
| <property name="hibernate.transaction.manager_lookup_class"
|
value="org.hibernate.transaction.JBossTransactionManagerLookup" />
| <property name="jboss.entity.manager.factory.jndi.name"
| value="java:/DAPem" />
| </persistence-unit>
|
My components.xml file is:
| <components>
| <component name="org.jboss.seam.core.init">
| <property name="myFacesLifecycleBug">true</property>
| <property name="jndiPattern">DAP/#{ejbName}/local</property>
| </component>
| <!-- 120 second conversation timeout -->
| <component name="org.jboss.seam.core.manager">
| <property name="conversationTimeout">120000</property>
| </component>
|
| <component class="org.jboss.seam.core.Ejb" installed="false" />
|
| <component name="em"
| class="org.jboss.seam.core.ManagedPersistenceContext">
| <property name="persistenceUnitJndiName">
| java:/DAPem
| </property>
| </component>
| </components>
|
The code where I call the "em" component is:
| public Object getAsObject(FacesContext facesContext,
| UIComponent component,
| String str)
| throws ConverterException{
| Object objReturn = null;
| if (str == null || str.length()==0 || EMPTY.equals(str)) {
| return objReturn;
| }
| EntityManager em = (EntityManager)Component.getInstance("em",
true);
| EntityProfilo profilo =
(EntityProfilo)em.find(EntityProfilo.class,new Integer(str));
| objReturn = profilo;
| return objReturn;
| }
|
I've read The Seam Reference Guide, step to step in the percistence section,
but my application don't work.
If you have an idea or if i have ommitted something, please help me.
Thanks...
