It looks like you are using an old version of ther EJB3 Persistence classes as targetEntity changed from being a String attribute to a Class attribute. Make sure you have installed everything correctly. Also, delete all your built class files and rebuild.

Thanks a lot, it was my mistake... I restart the installation with the new installer and every things is working perfectly...
