2. Re: OpenJPA and JBoss
hungtru Jul 29, 2008 9:38 AM (in response to hungtru)Hi there.
The strange thing is that I don't really have exceptions.
I'm using JBoss 4.2.2, OpenJPA 1.1.0, and Java 1.5.
In two beans, I am injecting the OpenJPA context via the @PersistenceContext(unitName="EventData")
But I never see these two beans deploy completely, as it says it is waiting for the persistence unit "EventData" to start.
My persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="EventData" transaction-type="JTA">
org.apache.openjpa.persistence.PersistenceProviderImpl
<jta-data-source>java:jdbc/ds</jta-data-source>
I have classes here
</persistence-unit>
I get the following in the JBoss server log:
2008-07-29 00:32:07,373 DEBUG [org.jboss.ejb3.Ejb3Module] Starting jboss.j2ee:service=EJB3,module=app_ejb-1.0.0.jar

It never hits the

Like all my other session beans do.
Does that mean that the bean is still waiting for the persistence unit? These are the only two that don't get deployed completely and available in JNDI and the only ones that use the persistence stuff.
Sometimes...and not always, i will get trace logs from OpenJPA:
70 EventData INFO [pool-13-thread-1] openjpa.Runtime - Starting OpenJPA 1.1.0
71 EventData TRACE [pool-13-thread-1] openjpa.Runtime - Properties: openjpa.EntityManagerFactory: default
99 EventData TRACE [pool-13-thread-1] openjpa.Runtime - No cache marshaller found for id org.apache.openjpa.conf.MetaDataCacheMaintenance.
195 EventData TRACE [pool-13-thread-1] openjpa.MetaData - Using metadata factory "org.apache.openjpa.persistence.jdbc.PersistenceMappingFactory@3a3b6b".
206 EventData TRACE [pool-13-thread-1] openjpa.jdbc.JDBC - OpenJPA will now connect to the database to attempt to determine what type of database dictionary to use. You may prevent this connection in the future by setting your openjpa.jdbc.DBDictionary configuration property to the appropriate value for your database (see the documentation for available values).
Not that I don't always get the openjpa.log, I don't know why though...it is rather inconsistent.
Thanks for any help.
