Thanks for the responses.

Re: Using friendly names for application entry points
I don't think you can specify a forward for the action of a form, can you? I'm not sure what Ted would define as entry points, but here are what I think of as entry points: index.do index.html default.asp index.asp home.asp home.html login.html :-) I think what he's saying is that something like usrSecChk.do?op=li (User Security Check - operation = login) is not terribly intuative for most folks, and that something should be used which is more friendly - more natural-language like - and, perhaps, something non-sophisticated users would be able to easily identify as a valid web name. Following this definition of friendly entry points, I think login is entirely acceptable.

RE: Using friendly names for application entry points
Your problem is that you are probably deploying the struts action with a .do mapping, whereas your user friendly name doesn't end in that extension and thus it never hits the struts framework for your global forward to work. Try writing or locating a servlet that you can map to that friendly name that will do a dispatch to the appropriate login .do. The form itself could post to your .do, but if you want a user-friendly entry point that you can publish or give verbally, your /performLogin would be a servlet that forwards to your login.do. Its about 2 lines of servlet code and an entry in your web.xml to do what you want.

Re: Using friendly names for application entry points
Additionally, you could make your entry point the directory's index page without using the index in the url: http://mycorp.com/struts/login/ would reference the index.jsp in the login directory. index.jsp would forward to index.do so it would go through the struts controller. The action mapped to index.do would simply forward to index2.jsp (or something else). You can use the struts ForwardAction to do this easily.
