Hi,
I am using EJB 2.1 for my application & using JBOSS 4.0.3 as Application server. Now I am using JBOSS Dynamic QL for "group by" clause as follows:-

-------------------------
public Collection ejbHomeSelectInStates(Set states)
throws FinderException
{
StringBuffer jbossQl = new StringBuffer();
jbossQl.append("SELECT g.orderno ");
jbossQl.append("FROM OrderMaster g ");
jbossQl.append("GROUP BY g.orderno");
Object[] args = states.toArray(new Object[states.size()]);
return ejbSelectGeneric(jbossQl.toString(), args);
}
--------------------------
& I have declared "ejbSelectGeneric" generic method is as follows using XDOCLET:-
--------------------------------------------------
* @jboss.query
* signature="Collection ejbSelectGeneric(java.lang.String ql, java.lang.Object[] params)"
* dynamic="true"
---------------------------------------------------

But when I am accessing function "ejbHomeSelectInStates" in my client, I am getting following error:-
---------------------------------------------
19:02:56,281 INFO [STDOUT] javax.ejb.FinderException: Error compiling ejbql: org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "GROUP" at line 1, column 36.
Was expecting one of:

----------------------------------------------

I really got bored now as I am trying to solve this problem since last 15 days. Also I searched on net for same, but I am not getting actual solution for it.
PLease help me to solve this problem, as my whole application got stuck due to this.
Thank you.
