Forms hang when it call reports

Question

Hi there,
In a one of my forms, there is button call report
the report object property like following:
name: report17
filename: f:\ora9ias_bi\reports\report11.rdf
execution mode: batch
communication mode:synchronous
report destination type:cache
report destination format:html
report server : repserver90
the trigger for the button is
eclare
     report_id report_object;
     v_rep     VARCHAR2(100);
     rep_status VARCHAR2(20);
begin
     report_id:=FIND_REPORT_OBJECT('report17');
     v_rep:=RUN_REPORT_OBJECT(report_id);
     rep_status:=REPORT_OBJECT_STATUS(v_rep);
     WHILE rep_status in('RUNNING','OPENNING_REPORT','ENQUEUED')
     LOOP
          rep_status := REPORT_OBJECT_STATUS(v_rep);
     end loop;
     if rep_status = 'FINISHED'or rep_status IS NULL THEN
          WEB.SHOW_DOCUMENT('HTTP://watfapp2.wat.michelin.com:7778/reports/
          rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver90','_blank');
     else
          message('Error when running report');
     end if;
     end;
     when I click the button, the forms hangs for very long time.
Could you please shed some light on it? thanks in advance

I change trigger like the following
eclare
     report_id report_object;
     v_rep     VARCHAR2(100);
     rep_status VARCHAR2(20);
begin
     message('before find');
     report_id:=FIND_REPORT_OBJECT('report17');
     message('before run');
     v_rep:=RUN_REPORT_OBJECT(report_id);
     message('after run');
     WEB.SHOW_DOCUMENT('HTTP://watfapp2.wat.michelin.com:7778/reports/
          rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver90','_blank');
     rep_status:=REPORT_OBJECT_STATUS(v_rep);
     WHILE rep_status in('RUNNING','OPENNING_REPORT','ENQUEUED')
     LOOP
          rep_status := REPORT_OBJECT_STATUS(v_rep);
     end loop;
     if rep_status = 'FINISHED'or rep_status IS NULL THEN
          WEB.SHOW_DOCUMENT('HTTP://watfapp2.wat.michelin.com:7778/reports/
          rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?'||'server=repserver90','_blank');
     else
          message('Error when running report');
     end if;
     end;
it hang on the command
report_id:=FIND_REPORT_OBJECT('report17');
the reports_classpath in default.env is
REPORTS_CLASSPATH=<ORACLE>/jlib/zrclient.jar;<oralce_home>/reports/jlib/rwrun.jar
What could cause the command report_id:=FIND_REPORT_OBJECT('report17');
hang on?
thanks again
