I am trying to start Liferay. It was working a few weeks ago. When I enter localhost:8080 I get a 404 error.
Here is the stack trace, where the error occurs. Does anyone have any ideas regarding how to fix this. I am using Liferay Portal 5.2.2 and Tomcat 5.5

It might be this issue, fixed in the current trunk. The subversion commit information is also included in Jira, so you can apply the same patch to your code. (see the fisheye information in the issuetracker)
Otherwise (and if splattne's link didn't help) we'll need more information:
