Getting varchar objects as "???" while using struct for oracle object type

Question

Hi all.
I have a problem whith VARCHAR values which is returned from an oracle function. The function returns an oracle type and I get it using STRUCT. I can get all non VARCHAR values of the TYPE like NUMBER and TIME without any problem. But when I get VARCHAR values, they all come as if equal to"???". I called the database function in TOAD and everything works perfect. It seems that somewhere in between we loose the information. Has anyone encountered such a strange problem?
Part of the code look like:
CallableStatement callState = null;
          ResultSet rs = null;
          UOAReturnType result= new UOAReturnType();
          try
               callState = getConnection().prepareCall("{?=call Call.UACBS.GETREDL(?)}");
               callState.registerOutParameter(1, OracleTypes.STRUCT,"CALL.TYPE_REDL_RO");
               callState.setString(2,msisdn);
               callState.execute();
               Struct RedlRoStrct = (Struct)callState.getObject(1);
               Object[] redlRo = RedlRoStrct.getAttributes();
               Struct redlStruct = (Struct)redlRo[0];
               Object[] redl =null;
               if(redlStruct!=null){
                    redl = redlStruct.getAttributes();
                    result.setMsisdn(redl[0].toString());
                    try {
                         result.setTime(UtilDate.getDate(redl[1].toString(),dateFormat,custLocale));
                    } catch (NullPointerException e2) {
                         result.setTime(null);
                         e2.printStackTrace();
                    result.setReason(Integer.parseInt(redl[2].toString()));
                    result.setSource(redl[3].toString());
               Struct opReturnStruct = (Struct)redlRo[1];
               Object[] opReturn = opReturnStruct.getAttributes();
               result.setResultCode(Integer.parseInt(opReturn[0].toString()));
               result.setResultDescription(opReturn[1].toString());Any idea will be appreciated.
Thanks.......

Hi,
I don't think it is a java problem.You can see time and number types because the characters are digits. My guess is that it has something to do with some settings on the client. Try to have the NLS_LANG environment variable appropriately set. Also try invoking your test script from sqlplus to see if the results actually work.
