[eclipselink-users] Lazy Fetch and weblogic issue

[Kim LiChong <Kim.Lichong@xxxxxxx>]

 Hi,

I am deploying a webapp to Weblogic 10.3.1.0 with eclipselink 1.1.  I am 
using resource injection in a ModelFacade class to get EntityManager 
Factory:


public class ModelFacade implements ServletContextListener {

 @PersistenceUnit(unitName = "BPWebappPu")
 private EntityManagerFactory emf;
 @Resource
 private UserTransaction utx;


I don't have any weave specific properties set in my persistence.xml 
either:
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence";>
<persistence-unit name="BPWebappPu">
 <description>BPWebapp Persistence Unit
 </description>
 <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
 <jta-data-source>jdbc/BPWebappDB</jta-data-source>
 <properties>
   <!-- for eclipselink 1.0 -->
   <property name="eclipselink.target-database" 
value="org.eclipse.persistence.platform.database.MySQLPlatform"/>

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

I am getting the following exception after deploying and hitting the 
home page for the first time:

Note that for both of the address fields "Address" mentioned in Person 
and Social event, they are defined as LAZY type fetches.

I had a colleague inform me that since the resource injection is being 
injected, the weaving should be transparent to me and should occur 
between WebLogic and Eclipselink.  However, the error seems to indicate 
that the weaving did not occur. Any ideas?

Thanks for the help,

Kim
