Popular JSP/Servlet/Portlet Error Log Viewer? [duplicate]

Question

After reading the latest Coding Horror post I wondered if there was a Java-based version of ELMAH out there in the open source community? A configurable JSP/Servlet/Portlet WAR that I can just drop into most servers and have a nice GUI for viewing the logs in the system. Anyone have a project to recommend?
