Question

i am getting the following error when I run a report from a form using 9i:
java.lang.NumberFormatException: mgb_5
this is my code:
DECLARE
repid REPORT_OBJECT;
vc_rep VARCHAR2(20);
vc_URL VARCHAR2(100);
vc_rep_job VARCHAR2(10);
BEGIN
repid := find_report_object('rep2');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_FILENAME,'C:\uni\mdt\cw1\rep2.rdf');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_EXECUTION_MODE, RUNTIME);
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_COMM_MODE, SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_DESTYPE, CACHE);
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_DESFORMAT, 'htmlcss');
SET_REPORT_OBJECT_PROPERTY(repid, REPORT_SERVER,'rep_mgb');
vc_rep := RUN_REPORT_OBJECT(repid);
vc_rep_job := substr(vc_rep,instr(vc_rep,'_')+1);
vc_URL := '/reports/rwservlet/getjobid' ||vc_rep_job||'?server='||get_report_object_property (repid,report_server);
web.show_document(vc_url, '_blank');
END;

Michael,
print out "vc_rep_job" to a message or alert to see if this contains a valid number. If this shows as a valid number try to manually type the access URL into a browser URL field. If this shows then you have a hidden character within your URL.
The PLSQL code looks okay.
