CMP Custom Finder Method Problem

Question

Hi everybody,
I have a problem about CMP Custom Finder Method.
I made CMP Entity Bean and deployed.
Then, I updated finder section in orion-ejb-jar.xml to add my custom finder query.
Here is updating finder section in my orion-ejb-jar.xml.
<finder-method query="(($schStartDate &lt;= TO_DATE($1,'MM-DD-YYYY a HH:MI') and $schEndDate &gt;= TO_DATE($1,'MM-DD-YYYY a HH:MI')) or ($schStartDate &lt;= TO_DATE($2,'MM-DD-YYYY a HH:MI') and $schEndDate &gt;= TO_DATE($2,'MM-DD-YYYY a HH:MI'))) and ($schRoom = $3)">
<!-- Generated SQL: "......" -->
<method>
<ejb-name>RoomSchedule</ejb-name>
<method-name>findBySchDateAndRoom</method-name>
<method-params>
<method-param>java.lang.String</method-param>
<method-param>java.lang.String</method-param>
<method-param>java.lang.String</method-param>
</method-params>
</method>
</finder-method>
<resource-ref-mapping name="jdbc/OracleDS" />
And, i restarted oc4j. so, oc4j redepoyed CMP bean.
But, when my client program called CMP Bean, lookup() was ok, but calling findBySchDateAndRoom() was bad.
I couldn't get any result collection.
Here is my client code.
Context ctx = new InitialContext();
Object ref = ctx.lookup("RoomSchedule");
roomScheduleHome = (RoomScheduleHome) PortableRemoteObject.narrow(ref, RoomScheduleHome.class);
String startDT = new String("07-30-2002 am 10:30");
String endDT = new String("07-30-2002 pm 05:20);
String roomID = "TEST";
Collection roomAllSch = roomScheduleHome.findBySchDateAndRoom(startDT, endDT, roomID1);
Iterator roomSchItr = roomAllSch.iterator();
int schQty = 0;
while (roomSchItr.hasNext()) {
roomSchedule = (RoomSchedule) roomSchItr.next();
if(roomSchedule.getStatus().equals("A"))
schQty++;
After excuting above code, schQty was still zero!!
Because Collection roomAllSch had not any items.
But, table ROOMSCHEDULE had 30 records which were same query condition in my database.
I traced SQL statement using P6Spy Class.
Here is spy.log.
1028006337814|10|0|statement|select * from RoomSchedule where ((RoomSchedule.schStartDate <= TO_DATE(?,'MM-DD-YYYY A.M. HH:MI') and RoomSchedule.schEndDate >= TO_DATE(?,'MM-DD-YYYY A.M. HH:MI')) or (RoomSchedule.schStartDate <= TO_DATE(?,'MM-DD-YYYY A.M. HH:MI') and RoomSchedule.schEndDate >= TO_DATE(?,'MM-DD-YYYY A.M. HH:MI'))) and (RoomSchedule.schRoom = ?)|select * from RoomSchedule where ((RoomSchedule.schStartDate <= TO_DATE('7-30-2002 ?@@| 01:00','MM-DD-YYYY A.M. HH:MI') and RoomSchedule.schEndDate >= TO_DATE('7-30-2002 ?@@| 01:00','MM-DD-YYYY A.M. HH:MI')) or (RoomSchedule.schStartDate <= TO_DATE('7-30-2002 ?@HD 12:00','MM-DD-YYYY A.M. HH:MI') and RoomSchedule.schEndDate >= TO_DATE('7-30-2002 ?@HD 12:00','MM-DD-YYYY A.M. HH:MI'))) and (RoomSchedule.schRoom = 'Earth')
1028006337824|10|0|statement|select RoomSchedule.schTitle, RoomSchedule.schStartDate, RoomSchedule.schEndDate, RoomSchedule.schDayAll, RoomSchedule.status, RoomSchedule.schRoom, RoomSchedule.reqUser, RoomSchedule.apprUser, RoomSchedule.purpose, RoomSchedule.relatoinID, RoomSchedule.schDesc, RoomSchedule.reqDate, RoomSchedule.apprDate from RoomSchedule where (RoomSchedule.schID = ?)|select RoomSchedule.schTitle, RoomSchedule.schStartDate, RoomSchedule.schEndDate, RoomSchedule.schDayAll, RoomSchedule.status, RoomSchedule.schRoom, RoomSchedule.reqUser, RoomSchedule.apprUser, RoomSchedule.purpose, RoomSchedule.relatoinID, RoomSchedule.schDesc, RoomSchedule.reqDate, RoomSchedule.apprDate from RoomSchedule where (RoomSchedule.schID = 0)
As you see it, two query statement were executed.
First query statement was ok and got some result records.
But, second query statement was bad so didn't get any result records.
I didn't understand why second query statement was executed.
When roomAllSch.iterator() was being excuted in my client program, second query statment was executed.
I couldn't believe....
What's wrong? Please help me....

I created CMP of EJB 1.1, I wanted to add a finder
there, but it didn't work.
the error message is:
"AccountEJB_vkbo0d_HomeImpl.java":
AccountEJB_vkbo0d_HomeImpl should be declared
abstract; it does not define findBySalary(float) in
AccountEJB_vkbo0d_HomeImpl at line 11, column 1I think I don't remember CMPs having finder methods anything other than abstract. The code goes in the deployment descriptor. I hope you atleast got that right.
