I'm trying to deploy my bundle in an OSGi container (namely Apache Servicemix). In it, I have my OpenJPA entities. I'm using OpenJPA version 2.3.0. When I try to access those entities through my Spring beans, using EntityManager, I get this error:
1 model WARN [SpringOsgiExtenderThread-4] openjpa.Runtime - An error occurred while registering a ClassTransformer with PersistenceUnitInfo: name 'model', root URL [bundle://220.0:1]. The error is logged along with this warning. Load-time class transformation will not be available.java.lang.reflect.UndeclaredThrowableException

Keep in mind that my persistence unit is called "model" - for a clearer overview. Can anybody help me to enhance my entities with maven?
Bellow is my snippet form my pom.xml:
<plugin>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa-maven-plugin</artifactId>
<version>2.3.0</version>
<executions>
<execution>
<id>JPA Enhance</id>
<phase>process-classes</phase>
<goals>
<goal>enhance</goal>
</goals>
</execution>
</executions>
<configuration>
<includes>**/entity/*.class</includes>
<excludes>**/entity/XML*.class</excludes>
<addDefaultConstructor>true</addDefaultConstructor>
<enforcePropertyRestrictions>true</enforcePropertyRestrictions>
</configuration>
</plugin>
Can anybody also tell me what should I put instead of entity in includes/excludes tags? Just having this, the error provided above occurs. I think I'm close to the solution, but can't manage to get it working.
