Tomcat verison & WebHome url?

Hi All, I am new to xwiki & have a couple of simple questions I was unable find in the documentation or the mailing list. First, the documentation on installing xwiki on Win2K says I need Tomcat v4.1. I was wondering if Tomcat 5 would work & if there were any issues I needed to be aware of before trying to run xwiki in Tomcat 5. Second, the url to the xwiki webhome is mydomain.com/xwiki/bin/view/Main/WebHome. I would like the url to be mydomian.com/xwiki. I noticed some people are using the redirect meta tag to accomplish this. xwiki.org seems to be using some other mechanism to other than a redirect to forward the user to the more complicated url. I was wondering if others have the same concern and how they resolved the issue. Thanks for your help!! Linda
