Найдите server.xml под tomcat, откройте его и удалите следующие вещи.

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">

<Valve className="org.apache.catalina.authenticator.SingleSignOn" />

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t "%r" %s %b" prefix="localhost_access_log." suffix=".txt"/> 

<Context docBase="MyProject" path="/MyProject" reloadable="true" source="org.eclipse.jst.jee.server:MyProject"/></Host>
