Re: Setting breakpoints in HTTPAPI callbacks

By chance, does the program or service program that you're debugging exist
in more than one library? If so, is the library list of the NEP the same as
the session that is running the STRDBG command? I've started using a fully
qualified library/pgm on the STRDBG command to debug NEPs for this reason.

Can't recall using STRDBG & STRSRVJOB...

OTOH, that call looks funny given the PR, why are they passing *NULL for

Cross-posted to RPG400 and WEB400 lists.

A colleague is using Scott Klement's HTTPAPI routines and is running
into an issue. They have the following code:

rc = http_url_post_xml( URL
: %addr(SOAP) + 2
: %len(SOAP)
: *null
: %paddr(Incoming)
: %addr(call_status)
: HTTP_TIMEOUT
: HTTP_USERAGENT
: 'text/xml'
: %trim(WSWSUR));

The program runs in a never-ending batch job. They execute STRSRVJOB on
the job and STRDBG on the program, and then set a breakpoint on the
first line of the "Incoming" procedure. It looks like the procedure is
being executed because it writes to a file and records are indeed being
written, but the breakpoint is never hit.

Before we dig a lot deeper or start using bigger debug hammers, is this
an issue anyone else has seen? I was wondering if perhaps there are
multi-threading concerns with the HTTP APIs that might complicate
service jobs.

Thanks as always!
