I have extended the JSPWiki code to be able to implement Sub-Wikis.

I call them WikiWebs.

The code is very raw and still needs to be worked out.

URL implementation

View:

<your_host>/JSPWiki/wiki/<WikiWebName>/<WikiPageName>

Edit, etc.:

<your_host>/JSPWiki/Edit.jsp?page=<WikiPageName>&web=<WikiWebName>

The repository is setup almost exactly the same:

<repository directory>
      /<WikiWeb1>
            - Main.txt
            - (Other wiki pages in the WikiWeb1)
            /OLD
                  /Main
                         - 1.txt (OLD version of Main.txt in WikiWeb1)
      /<WikiWeb2>
            - Main.txt
            - About.txt
            /OLD
...etc.. 

Inter-Web links are done like: [/WebName/PageName]

Attachment links are now done like [PageName+AttachmentName]

If you have any other questions just post them here.

Attached is the code. I will put up new code when I get through more stuff.
