Using the default report server

Question

This is the code that i have been using to call my reports from forms......
Till few days my reports where running fine with server that i had created but now i m getting errors as job ID 0 does not exist.....
So for the quick fix i want to run this reports using the default server.
So how can i find the name of the default server ...
because using the default server i can run the report in the url
for the default server to use the reports i have places the .rdf file in oracle_home\orant\reports\sample\demo folder
http:// pc938.stc.corp:8889/report/rwservlet?report=ttno.rdf&userid=mm/mm@orcl1&deformat=pdf&destype=cache&ticket_no=8100100
DECLARE
RO_Report_ID          REPORT_OBJECT;
    Str_Report_Server_Job VARCHAR2(100);
    Str_Job_ID            VARCHAR2(100);
    plid ParamList;
BEGIN
plid:=get_parameter_list('tmp');
if not id_null(plid) then
  destroy_parameter_list('tmp');
end if;
            plid := Create_parameter_List('tmp');
add_parameter(plid,'ticket_no',text_parameter,:control1.text_item740);
Add_parameter(plid, 'PARAMFORM', TEXT_parameter, 'NO');
    RO_Report_ID := FIND_REPORT_OBJECT('ttno');
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_FILENAME, 'ttno.rdf');
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_COMM_MODE, SYNCHRONOUS);
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_EXECUTION_MODE, BATCH);
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_DESTYPE, CACHE);
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_DESFORMAT, 'PDF');
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID, REPORT_SERVER, 'stcreportserver');
    SET_REPORT_OBJECT_PROPERTY(RO_Report_ID,REPORT_OTHER, 'PARAMFORM=NO');     
    Str_Report_Server_Job := RUN_REPORT_OBJECT(RO_Report_ID, PLID);
    WEB.SHOW_DOCUMENT('http://10.33.67.202:8889/reports/rwservlet/getjobid'||substr(Str_Report_Server_Job,
    instr(Str_Report_Server_Job,'_',-1)+1)||'?'||'server=stcreportserver&paramform=no
    &:ticket_no='||''''||:control1.text_item740||'''');

Here is a complete example u can check pls feel free to ask any ambigious syntax i can clear...
DECLARE
   PARAM_ID                                 PARAMLIST ;
   PARAM_NAME                           VARCHAR2(30) := 'REPORT_PARAMETER';
   ALRT                                         NUMBER;
   ERR_TXT                                   VARCHAR2(1000);
   repid                                         REPORT_OBJECT;
   v_rep                                        VARCHAR2(100);
   v_REP_SERVER_NAME       VARCHAR2(200);
   v_ip                                          VARCHAR2(100);
BEGIN
       PARAM_ID := GET_PARAMETER_LIST(PARAM_NAME);
       IF NOT ID_NULL(PARAM_ID) THEN
          DESTROY_PARAMETER_LIST('REPORT_PARAMETER');
       END IF;
       v_REP_SERVER_NAME := REP_SERVER_NAME;
  v_REP_SERVER_NAME :=  'rep_PC938'; and u have also to find it's ip and send it in the following url as
BEGIN
        SELECT  PARAMETER_VALUE  -- this is the selection of the server ip stored into a tabel u could assign it into a variabel.
        INTO   v_ip
        FROM GENERAL_FIXED_PARAMETERS
       WHERE PARAMETER_ID = 'REPORT_SERVER_IP';
       EXCEPTION
       WHEN OTHERS THEN   
       Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);
       Message ('OTHERS' || SQLCODE || ' And ' || SQLERRM);     
END;
       PARAM_ID := CREATE_PARAMETER_LIST(PARAM_NAME);
       ADD_PARAMETER(PARAM_ID,'PARAMFORM',TEXT_PARAMETER,'NO');   
       ADD_PARAMETER(PARAM_ID,'COPIES',TEXT_PARAMETER,:COPIES);
       ADD_PARAMETER(PARAM_ID,'P_DISPLAY',TEXT_PARAMETER,:DESTYPE);
       ADD_PARAMETER(PARAM_ID,'DESFORMAT',TEXT_PARAMETER,'pdf');
       ADD_PARAMETER(PARAM_ID,'group_id',TEXT_PARAMETER, :group_id);
         repid := find_report_object('WH_R01_GRP_ITEM');
         SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER,v_rep_server_name);     
         v_rep := RUN_REPORT_OBJECT(repid,PARAM_ID);
  WEB.SHOW_DOCUMENT('http://'||V_IP||'/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?server='||v_REP_SERVER_NAME,'_blank');
END;
Hope in Shaa Allah it helps u
God Bless u for Keeping up El-Salah's Time :)
