Hi,
I am developing my CMP EJB's using EJB 2.0 Specification. In my one of CMP EJB there is a ejb-finder method with EJB QL as following:-
============================================================
"SELECT Object(b) FROM PartsMaster as b where b.partno like ?1 or b.description like ?2 ORDER BY ?3"
=============================================================
But when I am deploying my Bean to my application server (I am using JBOSS4.0), I am getting Error as follows:-
=======================================================
18:33:30,359 WARN [ServiceController] Problem starting service jboss.j2ee:jndiName=ejb/PartsDetail,service=EJB
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT Object(b) FROM PartsMaster as b where b.partno like ?1 or b.description like ?2 ORDER BY ?3'; - nested throwable: (org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "3" at line 1, column 97.
Was expecting one of:
<NUMERIC_VALUED_PATH> ...
<STRING_VALUED_PATH> ...
<DATETIME_VALUED_PATH> ...
)
at org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLQuery.<init>(JDBCEJBQLQuery.java:52)
at org.jboss.ejb.plugins.cmp.jdbc.JDBCCommandFactory.createEJBQLQuery(JDBCCommandFactory.java:60)
at org.jboss.ejb.plugins.cmp.jdbc.JDBCQueryManager.start(JDBCQueryManager.java:272)
=======================================================

However above EJB Query is working fine without "ORDER BY" Clause into it.

so Why I am getting this error when I am using ORDER BY in my EJB QL?
Is ORDER BY not available in EJB2.0 Spec?
please help me.
Thanx in advance.
Prash
