Tomcat war file JasperException

[Geert Claes]

I would like to get started with Java development on Linux (Gentoo),
so, I emerged the latest Sun SDK, Eclipse 3 and Tomcat 5. The problem
is when I deploy a war file (JSPWiki) it says the deployment is
successful, but when I try to access the web application I get the
following error:

org.apache.jasper.JasperException: WikiEngine has not been properly
started. It is likely that the configuration is faulty. Please check
all logs for the possible reason.

Is this an access privileges thing?
