i am working in jsp webapplication in ubuntu. my tomcat6 is located =>/var/lib/tomcat6
here one folder is there "webapps".i have put my web page in webapps/ROOT. and i run from browser like localhost:8080/xyz.jsp it works fine. but now i want to change directory from webapps. for that i have create new directory testing123 in var/lib/tomcat. and configure in /var/lib/tomcat6/conf/server.xml which is given below.

```
        <Host name="localhost"  appBase="testing123"
        unpackWARs="true" autoDeploy="true"
        xmlValidation="false" xmlNamespaceAware="false">

```

and restart tomcat and cut from webapps and pest my xyz.jsp file in testing123 and try to run localhost:8080/xyz.jsp i get error 404. so kindlly tell me how to change directory. 

thank you in advance.
