Hi,
I tried by manually adding the java agent in my jvm options -javaagent:/ apache-openjpa-2.2.2/lib/openjpa-all-2.2.2.jar following examples 5.2 and 5.3 under section 2.3 at http://openjpa.apache.org/builds/2.1.1/apache-openjpa/docs/ref_guide_pc_enhance.html#ref_guide_pc_enhance_build . But even that hasn't helped .I still get the entity not enhanced problem. Regards Divya From: Divya K Konoor/India/IBM To: users-h...@openjpa.apache.org, dev-h...@openjpa.apache.org, Date: 09/25/2013 07:19 PM Subject: Entitiy not enhanced Hi, I use a container (Webshphere liberty that internally uses openjpa). I have multiple OSGi persistence bundles .Each has its own persistence unit ; all of these talk to the same database.The JPA entities bundled within each persistence bundle is defined under the <class></class> tag of the persistence.xml. Some of these entities have relationship or dependency on the entities bundled with another persistence bundle in which case the dependent entities are added in the <class> tag of the former's persistence.xml I see the following error message when I start my liberty server: This configuration disallows runtime optimization, but the following listed types were not enhanced at build time or at class load time with a javaagent: " [err] <openjpa-2.2.1.1-SNAPSHOT-r422266:1431746 fatal user error> org.apache.openjpa.persistence.ArgumentException: The type "class com.xxx.ProbeConfiguration" has not been enhanced.

The above log statement seems to indicate that one or more JPA entities have not been enhanced during runtime.I saw a brief mention about this at http://openjpa.apache.org/builds/2.1.1/apache-openjpa/docs/ref_guide_pc_enhance.html#ref_guide_pc_enhance_dynamic "If a javaagent is not provided via the command line and OpenJPA is running on the Sun 1.6 SDK or IBM 1.6 JDK (SR8+), OpenJPA will attempt to dynamically load the Enhancer that was mentioned in the previous section. This support is provided as an ease of use feature and it is not recommended for use in a production system. Using this method of enhancement has the following caveats: The dynamic runtime enhancer is plugged into the JVM during creation of the EntityManagerFactory. Any Entity classes that are loaded before the EntityManagerFactory is created will not be enhanced. " I also noticed the following in the logs: openjpa.DynamicEnhancementAgent: false . I was expecting it to me openjpa.DynamicEnhancementAgent: true . I manually added the following jvm option -Dopenjpa.DynamicEnhancementAgent=true after which the logs show openjpa.DynamicEnhancementAgent: true but I hit the same entitiy not enhanced issue. Apart from build time enhancement , is there anything that can be done to ensure that all JPA entities are enhanced during runtime. Thanks Divya
