Debugging Tomcat Startup
favorite 7 I'm getting 500 Internal Server errors when I try to make an HTTP POST to a specific address in my app. I've looked into the server logs in the custom log directory specified in the virtual hosts file, but the error doesn't show up there so debugging this has been a pain in the ass. How do I cause Apache to log Internal 500 errors into the error debugging tomcat application in eclipse log? apache error-logging share|improve this question edited Dec 11 '13 at 6:05 Eric Leschinski 46.3k23221190 asked Jan 19 '11 at 3:04 wcolbert 5452821 I had same issue using PHP with virtual hosts....no errors (Apache2, Ubuntu). Ended up being missing PHP modules (mysql, json, etc.) –user484474 Aug 7 '11 at 19:57 On ours, it was sending them to the access log (presumably because from Apache's point of view, it was working correctly and merely passing them along, from a deeper layer -- in our case, Passenger/Rails).

This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error. in perl if you forget print "content-type
