Please read the infoCenter tutorial about using WebSphere, or download and read any or all of the WebSphere 5.0 administration redbooks from the IBM redbook site. WebSphere does not have a "default directory". It is not
TomCat. You must install applications into WebSphere in the form of fully built EAR files (which can be built using the application assembly tool) with the WebSphere administrative console.
There is nothing at
http://localhost:9080. You must provide a context root for some application such as
http://localhost:9080/WSSamples to access an application such as the Samples application.
