orion application server

[mahadev ramalingam]

hi,
I added a new application in orion application server.
apart from the defaultwebapp in global application, I have my application-name under application and my web-app under my application-name. it has a web-inf and web.xml.
my application also has a meta-inf and application.xml in it.
now, the problem is, I'm not able to call the files in it thru the browser.
before adding this application, i could call the files of default webapp but now, i couldn't call/access any of the fielis. It says internal server error.
can anyone help me out...
or if anyone has a detailed procedure of how to add an unpackaged application into orion?
orion documentation is not clear!!!
