Hi, I have a simple project where I have a POJO class 'A' annotated with
@Entity. I have also created a <class> tag for this in the persistence.xml
under META-INF of the webapp. Now when I am trying to do something like A a
= new A(); inside a public method of @Stateless EJB, I get the following
error:
SEVERE: Servlet.service() for servlet SomeServlet threw exception
javax.ejb.EJBException: The bean encountered a non-application exception;
nested exception is:
java.lang.NoClassDefFoundError: Could not initialize class

Here's what the persistence.xml looks like
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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_2_0.xsd";>
<persistence-unit name="PU" transaction-type="JTA">
<jta-data-source>DS-JTA</jta-data-source>
<non-jta-data-source>DS-Non-JTA</non-jta-data-source>
<class>com.foo.entities.A</class>
<properties>
<property name="openjpa.jdbc.DBDictionary" value="mysql"/>
</properties>
</persistence-unit>
</persistence>
...
Finally the injection of EntityManager inside @Stateless bean named LogEvent
is done as follows...
@PersistenceContext(unitName="PU")
private EntityManager em;
the line which triggers the error is as follows...
A a = new A();
I'm using apache-tomee-1.5.2-20130212.041100-67-plus [SNAPSHOT]
Thanks
