Hello,
the easiest way is to put your web aplication to the tomcat/webapps
directory. Because the paths in server.xml are relative to that webapps
dir. For example you have webapps/examples defined in you server.xml. So
put your test directory to the webapps folder and edit your server.xml to
<Context path="/test" docBase="webapps/test" debug="0" reloadable="true"/>
If that doesn't work there is an essential error in you configuration. It's
also allways a good hint to try to access the examples in
localhost/examples.
