Parameter Type Conflict: sqlType=2003

[nandini lagunia]

I am using Oracle 9i and jdk 1.4.
I have written a stored procedure that takes Array and returns Array.

For that I've crteated a type like as follows:-
CREATE TYPE workorderArr AS varray(100) OF varchar2(100);

My stored procedure looks like:-

CREATE OR REPLACE PROCEDURE delcust_order_byworkorder_mul (

reqArr IN workorderArr,

responseArr OUT workorderArr



)

IS

orderstatus INTEGER (2) := 0;

workordernumber VARCHAR (9) :='w';



BEGIN


responseArr := workorderArr('');

FOR i in reqArr.first .. reqArr.last LOOP
-- SOS. PLEASE HELP ME!!!
dbms_output.put_line(workordernumber);



END LOOP;









END;


Now I am trying to execute this Stored procedure through my java code as follows:-

String[] sendArr={"12","32","55"};	//used in OUT paramete
		String[] rcvArr=new String[10];		//for collecting IN parameter

		con=getConnection();	//returns the connection reference
		CallableStatement cs=null;
            	cs = con.prepareCall("{call DELCUST_ORDER_BYWORKORDER_MUL(?,?)}");
            	oracle.sql.ArrayDescriptor descriptor =ArrayDescriptor.createDescriptor("WORKORDERARRAY", con );
            	oracle.sql.ARRAY arraystr =new ARRAY( descriptor, con, sendArr);
            	cs.setArray(1, arraystr);

            	cs.registerOutParameter(2,java.sql.Types.ARRAY);	//line no 45. this is where I am getting exception
		cs.execute();
		java.sql.Array rcvArrData=cs.getArray(2);
		
		rcvArr=(String[])rcvArrData.getArray();

This program compiles fine but upon running, it gives me following exception:-


java.sql.SQLException: Parameter Type Conflict: sqlType=2003

I don't have any clue what's wrong with the code.
Any kind of help will be highly appreciated.
Thanks
