Re: HTTP 500 Error -- WEB400

David,

Start a service job over the CGI job running in the QHTTPSVR sub-system.

If you do a WRKACTJOB SBS(QHTTPSVR) you'll see probably 5 jobs for your
instance. The CGI jobs, on my system anyway, are the second and third jobs
in the list. If you display the jobs and look at the joblog, it will tell
you that the job is a CGI job.

Then you'll do a STRSRVJOB JOB(999999/QTMHHTTP/Instance name) where 999999
is the job number and instance name is the Job name. This should be the
name of your instance. Then issue a STRDBG on the program you wish to debug
and set a break point. Execute it via your web interface. It should stop at
the breakpoint on the session on which you keyed the STRDBG. Then you can
step through as normal.

It may take some experimentation finding which job is servicing the
request.



Good Luck

Mark

Justin:
How do I STRDBG on a program then call it from the web?  The debug
session whould be over a differnt job?  Am I missing something?

Andrew:
I'm not that far yet.  The program never gets executed for me to mess
all those things up.  Thanks.

Peter:
I've tried that, below is the log, and a portion of the "very verbose"
job:
