problem updating a resultset in jdbc when returning cursor from function

Hi,
So, I'm spent a lot of time looking around this group but haven't been able to solve my problem yet. Basically, I'm trying to figure out how I can achieve an updatable recordset in Java which has been returned from a oracle function via a cursor.

When I try to move to an insert row I keep getting an exception saying my resultSet is read only. I'm wondering if it has something to do with casting to a ResultSet. Does it automatically become read-only?

Everything works fine if my query is not a function call but is a select query.
Any help would be much appreciated! Thx. RAchel

Here's the Java:

String query = "begin ? := " + INSERT_OR_UPDATE_ENTITY_PROC + " (?); end;";

            stmt = conn.prepareCall(query, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);

            stmt.registerOutParameter( 1, OracleTypes.CURSOR);
            stmt.setBytes(2, m_user.getId().toByteArray());
            stmt.execute();
      
          
            rset = (ResultSet)stmt.getObject(1);

            rset.moveToInsertRow();

Here's the SQL:
  FUNCTION InsertOrUpdateEntity(vId IN RAW) RETURN cursorType    IS
   l_cursor cursorType;
   BEGIN
   OPEN l_cursor FOR SELECT entityId, entityCd

        FROM ENTITY WHERE entityId = vId;    RETURN l_CURSOR;
   END; Received on Wed Sep 25 2002 - 15:15:14 CDT
