This article addresses the issue where Tomcat starts successfully in Eclipse but fails to connect to http://localhost:8085/, resulting in an HTTP 404 error. The cause is Eclipse's control over deployment preventing the default homepage from being deployed. The solution involves configuring Eclipse to use the Tomcat installation by selecting 'Use Tomcat installation' in server settings, removing modules, and publishing. This restores access to the default resources.

This paper provides a comprehensive analysis of the SLF4J static logger binder loading failure issue encountered when using Maven plugins in Eclipse Juno, Indigo, and Kepler versions.
