Subject Re: JSPWiki "Special Pages"
Date Wed, 28 Nov 2007 15:52:23 GMT

Most client requests to a JSPWiki site pertain to the simple display of 
the contents of ordinary wikipages.  (Other types of requests are 
handled, not by Wiki.jsp, but by other 'first line' JSP modules, such as 
Install, Captcha, SisterSites, Comment, Login, Logout, Preview, 
PageModified, PageInfo, Rename, Delete, Search, Message, 
UserPreferences, Diff, Vote, EditGroup, LostPassword, Edit, 
NewBlogEntry, NewGroup, or Group).

For these requests to display the contents of ordinary pages, handled 
initially by Wiki.jsp, ViewTemplate.jsp provides the 'look and feel' 
aspects that surround the unique content stored in a wikipage. It, in 
effect, wraps the unique wikipage content with the standard header, 
footer and menus.

The challenge I (and others, I think) face is how (within JSPWiki) to 
display content from a custom JSP so it has the same look and feel as 
wikipages (and to make JSPWiki treat that custom JSP as just another 
wikipage).  I mentioned that my (admittedly distasteful) approach was to 
modify ViewTemplate.jsp to accomplish this. 

However, you seem to suggest/imply that there is indeed a way to do this 
without having to modify ViewTemplate.jsp.  Could you explain this 
could/should be done?  (I ask because if I can accomplish this without 
changing ViewTemplate.jsp, I would be more than delighted.)

I realize I may be overlooking something very obvious that deserves a 
'duh' response, but I'll take the risk. 


PS: Maybe via a plugin that directly loads a JSP?
