Sorry, I should have posted that. If I remove org.apache.commons.logging_1.0.4.v200706111724.jar from WEB-INF/eclipse/plugins/, the server starts with no errors. Then if I open the application in a browser, the application is not available (or at least the index.jsp page is not). This is what I see in the browser: *********************************************** HTTP Status 404 - ProxyServlet: /nexus-5-0-admin/index.jsp type Status report message ProxyServlet: /nexus-5-0-admin/index.jsp description The requested resource (ProxyServlet: /nexus-5-0-admin/index.jsp) is not available. JBossWeb/2.0.0.GA *********************************************** Attempting to open that index.jsp does not produce any ERROR or WARN messages in the log. Thanks for your help.
