Hi Gul,The root cause is class path or class loader problems. A class loaded by a different class loader is considered to be a different class by Java even if it has the same name.
Does this help? Craig On Nov 23, 2007, at 7:30 AM, Gul Onural wrote:
Hi, We are observing a strange exception sporadically, for different JPA classes. When we replace an ear file containing our jar with our jpa classes, we see an exception thrown : "2?com.mycompany.UserDetails incompatible with com.mycompany.UserDetails" We see this exception even the class in question is unchanged. Did anyone saw this type of exception before ? What would be the route cause of this ? Gul
