Hey all,
I'm getting an error when I'm trying to access a CGI program. Here's my
scenario: I have an initial CGI RPG program that displays requisitions to
a user...they click on a link that takes them to another page...on this
2nd page, I have 2 buttons...one executes a CL program and one takes them
back to the original page that displays requisitions...here's my
problem...the user can click on the 2nd button to take them back to the
first page just fine...if they click on the first button (that calls the
CL program) it should take them back to the first page once some
processing is complete. However when I click on this first button, I get
a 500 Internal Server Error - Cannot read script output pipe. So, I check
out the spool files for QTMHHTTP and see the following inside a spool file
called QZSRHTTPTR:
User Trace Dump for job 057806/QTMHHTTP/CGIHTTPSVR. Size: 300K, Wrapped 0
times.
