EJB-QL with Date parameter

Question

Hi All,
I have used the follwing EJB-QL with java.sql.Date as one of the parameter.
<query-method>
<method-name>findByLeaveEmpTypeDateStatus</method-name>
<method-params>
<method-param>java.lang.Integer</method-param>
<method-param>java.lang.Integer</method-param>
<method-param>java.sql.Date</method-param>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>
<![CDATA[select object(o) from LeaveBean o where o.leaveId = ?1
            and o.empTypeId = ?2 and o.createdDate = ?3 and o.status = ?4]]>
</ejb-ql>
The server log throws the following exception.
Test Name : tests.ejb.entity.ejbql.EjbQLFromCmpEntityDescriptor
Test Assertion : EJB 2.0 Spec Chapter 10 Container managed persistent
queries should comply with specification in its sytax and semantic rules
Test Description : Error: [ select object(o) from LeaveBean o where
o.leaveId = ?1 and o.empTypeId = ?2 and o.createdDate = ?3 and o.status = ?4 ]
has parsing error(s)
Exception occured : [Invalid type for expression (o.createdDate  = ?3)
EJB QL statement : 'select object(o) from LeaveBean o where o.leaveId = ?1
and o.empTypeId = ?2 and o.createdDate = ?3 and o.status = ?4'
EJB QL method    : public abstract LeaveLocal LeaveLocalHome.findByLeaveEmpTypeDateStatus
(java.lang.Integer,java.lang.Integer,java.sql.Date,java.lang.String)
throws javax.ejb.FinderException
All the ejb-ql statements with Date as parameter only are throwing the above exception.
Instead of java.sql.Date, I have tried with Timestamp and Long, but the same exception throws.
I am using Oracle as my DB.
The same application with Date as parameter works fine with Weblogic and JBoss.

We are having the same problem: We have timestamps in the database and the ejbql is this:
SELECT Object(e) FROM EstimateOrder e WHERE e.idDistributor = ?1 and e.ordDateEntered > ?2 and e.ordDateEntered < ?3
The verifier gives this error:
Exception occured : [Invalid type for expression (e.ordDateEntered  > ?2)
Can timestamps be used as input params in ejbql and the used in comparisons?  We tried the "between" also with the same results.
