to configure the server.policy of the jes application server to avoid the hibernate cglib enhancement exception.

 when using jes application server, e.g. 8.1pe, the cglib for hibernate persistence object enhancement maybe throw excepti just like the followings:

it maybe the jes application server policy issue. try to append this in server.policy for application server (../appserver/domains/domanx/config/server.policy), and it should work:
grant {
permission java.lang.reflect.reflectpermission "suppressaccesschecks";
};
grant {
permission java.lang.runtimepermission "setc
};
grant {
permission java.lang.runtimepermission "getprotecti
};
