where is the apache error log?

When servoy is installed under windows (server 2008 r2) where is the apache error log.
The
c:\program files\servoy\application server\server\logs folder only contains the localhost access log files.

I need to find the error log files - so I can try to diagnose an internal apache 500 error.
Are the error log files created by default or do i have to turn them on/

ok
ignore that - it seems that the info is supposedly in servoy_log.txt ?
problem is that log shows nothing of use…should it be showing me the reason for a tomcat ‘internal server error - 500’ ?
if not - how/where do I diagnose such problems?

Try “Turn trace on” in the servoy-admin / Server log page, maybe this will give you more info about your server error…
