Hi Excuse me for the late reply Thanks for your replies and helps My problem was solved . I have an embeddable class that I use it as embedded property in some entity class and we forgot to list it on the persistence.xml file and then enhancer didn’t enhance it .I think this embeddable class was the cause of my problem. I simply add it to the list and my problem was solved. Also OpenJPA enhancer works fine in glassfish .I can see enhancer and cache operations in glassfish logs . Thanks all Ahad Javadi
