Tomcat 500 Server Error

[brettmostert]

Hi,

We are experiencing the following errors when starting tomcat... any help would be most appreciated...

It seems this results in us getting a 500 server error when navigating to a tomcat app.

Issue resolved....

Hi,

This issue has been resolved thought i would let everyone know incase someone else battles with this...

It was a corrupt config file in tomcat... specifically the tomcat-users.xml file. The xml was corrupted... by what i do not know. I can only image it was done by plesk.

Regards,
Brett
