url forbidden

[Karri Niemel�]

I'm trying to deploy a simple web application to orion (made with sun's j2ee
tool)
It goes "in" fine and all the binding etcetc works, but then I get 403 url
forbidden error ,when trying to look at that url.
The web application is just made out of one servlet (simple helloworld
thingy)

is this A) Some sort  of security issue
         B) Something wrong with my servlet mappings or..?
