I am using hibernate 3.2 with struts 1.2 framework
I got this exception when i m trying to load the
object
I am using this code to load the
object
public Currentprofile findById(java.lang.String id) {
log.debug("getting Currentprofile instance with id: " + id);
try {
Currentprofile instance = (Currentprofile) getSession().get(
"com.hibermappings.Currentprofile", id);
return instance;
} catch (RuntimeException re) {
log.error("get failed", re);
throw re;
}
}
