[jboss-user] [EJB 3.0] - Illegalargumentexception on calling namedquery

[aukenoppe]

Hi,

i have a entitybean user, which has a namedquery User.getAllUsers.
when i call this query from my sessionbean:
Query q = getEm().createNativeQuery("SELECT object(u) FROM User u WHERE "
  | 				+ col + " LIKE :value", User.class).setParameter("value", value);

or the namedquery
  | @NamedQuery(name = "User.getAllUsers", query = "SELECT u FROM User u"): 
  | 

then i get this stack from the client progam:
xception in thread "main" javax.ejb.EJBException: java.lang.IllegalArgumentException: wrong number of arguments
  | 	at org.jboss.ejb3.cache.simple.SimpleStatefulCache.create(SimpleStatefulCache.java:337)

  | 	at 
  | org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:166)

the serverstack is as follows:
