Subject migration woes
Date Mon, 19 Nov 2001 21:06:50 GMT
Moved from a working webapp under FreeBSD, Tomcat 3.2, apache 1.3.12
to Windows 2000, tomcat 3.2.3 and apache 1.3.17.

After getting around the tomcat/apache configuration quirks I finally
could fire up my webapp and it showed up partially with classes
not recompiled.

But since I had some hard wird unix paths in my servlets I had to recompile
and after doing this alread the central startup servlet bombs.

I had a -deprecation warning during compilation (compiled using jdk1.3.1_01)

Can anyone read something out of this picture:
In browser:

Error: 500

Location: /servlets/servlet/Hello

Internal Servlet Error:

There is no tomcat.log BTW.
