It should be not the web.xml of your application, but the default one.

See conf/web.xml in the official distribution of Tomcat from tomcat.apache.org.

The distinct feature is that it has a long list of mime-types. It is
also the one that defines the JSP and default servlets. Of course, all
of them can be in webapp's web.xml.

See RUNNING.txt in the official distribution.

When using CATALINA_BASE, the following folders are moved there:
/conf
/logs
/webapps
/work
/temp

You can remove those folders from CATALINA_HOME.


The following folder can be created for the sake of placing
"setenv.sh" (setenv.bat) file there:
/bin

The rest of /bin files remain in CATALINA_HOME. That is, there are the
following folders:
/bin
/lib

Also I usually have some shared libraries in CATALINA_BASE. That is, I
have a /lib folder there, but for that you need to edit your
conf/catalina.properties file, or wait for Tomcat 6.0.21. Such feature
is proposed to be included in that release.

Access rights? Or may be you did not shutdown your previous Tomcat instance?

Also, if there were confusions with what user was used to start the
Tomcat, please check what user is the owner of your log files (maybe:
delete them all) and remove the files that are in the /work folder
before starting Tomcat.

Best regards,
Konstantin Kolinko
