Subject Glassfishv3 + OpenJPA-2.0.0: Enhancer not working
Date Mon, 19 Jul 2010 13:04:05 GMT
Hello,

I have a Glassfishv3 running here and *need* to use OpenJPA-2.0.0.

I'm currently having two different setups in our persistence.xml; here's the working one:

<persistence 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" version="1.0">
	
	<persistence-unit name="myApplicationPersistenceUnit" transaction-type="RESOURCE_LOCAL">
		<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
		<jta-data-source>jdbc/MyDataSource</jta-data-source>
		<properties>
			<property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE"/>
			<!-- <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema"/> -->
		</properties>
	</persistence-unit>
</persistence>

This one has the disadvantage, that the entity classes used (here: Class1 and Class2) need
to be listed twice (in persistence.xml and pom.xml), to configure the Enhancer outside of
Glassfish and push the results into OpenJPA's MetaDataFactory. Of course, keeping two lists
of classes up to date is error prone, especially as the following error is produced, if this
step is omitted or some classes are forgotten:

<openjpa-2.0.0-r422266:935683 nonfatal user error> org.apache.openjpa.persistence.ArgumentException:
An error occurred while parsing the query filter "SELECT g FROM Class1 g ORDER BY g.dateCreated
DESC". Error message: The name "Class1" is not a recognized entity or identifier. Known entity

Now, we want to use Glassfish's automatic Enhancer support, as there seems to be a requirement
to do so for JavaEE 5 compatible app servers (see: http://openjpa.apache.org/builds/latest/docs/manual/ref_guide_pc_enhance.html#ref_guide_pc_enhance_runtime_container).

As the just copying the openjpa lib (plus required serp-1.13.1 library) to Glassfish's\domains\domain1\lib
directory doesn't seem to help, I installed the OSGi-compatible packages (it also requires
commons-lang-2.4.0, commons-collections-3.2.1, commons-logging-1.1.1, commons-pool-1.5.3 as
well as serp-1.13.1; all obtained from springsource.com) and used the following persistence.xml:

<persistence

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

		</properties>
	</persistence-unit>
</persistence>

(Note: This persistence.xml was inspired by a IBM WebSphere 6.1 article, (although WebSphere
7 is our client's target platform; see: http://www.ibm.com/developerworks/websphere/techjournal/0612_barcia/0612_barcia.html)

After installing all the libraries through felix's admin web app, all bundles were shown to
be actived, but when deploying the application, the following Exception came up:

As a result, I have two questions:
1) how do I enable OpenJPA's Enhancer to run at deployment time?
2) if question 1) requires the installment of OpenJPA-2.0.0 as a OSGi bundle, what else do
I need to do to get it running?

Note 1: no, I cannot use Glassfishv3's integrated toplink support, as our target platform
is IBM WebSphere 7 w/ OpenJPA
Note 2: this post got cross-posted at Glassfish's forum (http://forums.java.net/jive/thread.jspa?threadID=151839).
I'll report it here, if something happens.

Thanks a lot for your support and please do not hesitate to ask for anything else you might
need to understand or help.
