Próbuję porównać wartości z trzechResultset, ale wydaje się, że wyjątek jest taki, że próbuję go uruchomić. Czy ktoś może mi pomóc, gdzie się nie uda. Będę wdzięczny za każdą pomoc. Oto fragment kodu, który zgłasza błąd:

<code>    java.sql.Connection connDB = null;

    try {

        + "/" + dbName, userName, password);

       System.out.println("Connection established : [" + connDB.toString() + "]");

       java.sql.Statement pstmt = connDB.createStatement();

       java.sql.Statement pstmtShifts = connDB.createStatement();

               while (rset2.next()){

                    if((rset2.getDouble("debit")<=0 ))

                    else if((rset2.getDouble("debit")==rsetShifts.getDouble("amount")) &&

              shiftsVector.addElement(rset.getString(1)+":"+rsetShifts.getString(1)+":"+status);
