Hi folks,
I have the following problem:
My persistence.xml contains two persistence-units and looks like that:
<?xml version="1.0" encoding="UTF-8"?>
<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="pu-name1f" transaction-type="JTA">
<jta-data-source>db1</jta-data-source>
<class>...</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties/>
</persistence-unit>
<persistence-unit name="pu-name2" transaction-type="JTA">
<jta-data-source>db2</jta-data-source>
<class>...</classes>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties/>
</persistence-unit>
</persistence>
Then I have a Singleton Bean which contains code that uses JPA classes to access a MySQL database via EclipseLink and another stateless bean which access JPA classes in another MySQL database also via EclipseLink as specified in the persistence.xml
I use the following code to initialize the EntityManager via a factory and execute a NamedQuery:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("pu-name1");
EntityManager em = emf.createEntityManager();
Query Stat = em.createNamedQuery("Vc200SStat.findByVC200ID");
eStat.setParameter("vC200ID", Id);
List<Vc200Stat> StatList = Stat.getResultList();
But it gives me the following error message:
[#|2010-04-16T09:41:55.550+0200|SEVERE|glassfishv3.0|de.aco.odin.core.StatDataBean|_ThreadID=31;_ThreadName=Thread-1;|The log message is null.

The Entity classes are generate via Netbeans 6.8 and are not changed at all.
Does anyone have a clue where the problem could be?!?
Cheers and thanks in advance
