Service Entry Point
The following is a tip declaring how to debug CGI Pgms via WDSC's SEP (Service Entry Point) functionality. After right clicking on the PGM to set a SEP, it will of course be added to the SEP view. But running the program doesn't cause debugging to happen at this point. The reason being is because the debug isn't running under your iSeries profile (e.g. JSMITH) and is instead running under QTMHHTP1. Right click on the SEP in the SEP view that was just created and select Modify and change the user from JSMITH to QTMHHTP1. Now run the CGI program again and it SHOULD bring up the iSeries Debugger in WDSC.
