looking at your install path, I assume that you're using jrun 3.x. Unfortunately I don't use jrun 3.x at home, but from memory, click on 'applications' in the lhs of the jmc. On the right hand side
you should see various options, create/deploy/remove application, etc. Choose create an application. Once the application has been created, you should notice, again on the left hand side, that a node has been created for your app. Expand the node, and you should see servlet mappings and another servlet node (servlet xxx?). In the servlet mappings section you should be able to associate a path (e.g. /path) w/ an alias, and in the other section (aliases in jrun 2.3.3) you can establish an alias for a class.
search the pdfs in the docs folder and you will find a ton of information on establishing aliases for servlets (p 110~??) if my post is incoherent.
If you're in fact using jrun 2.3.3 and your install path is just a coincidence, launch the administrator from the system tray (assuming winnt, etc.) and click on the jcp for jse (didn't you mention that you were going to use iis in a different
thread, your url looks as if you're still using the jws), and then click service config. You should see servlet mappings and aliases in the first few tabs.
