(I apologize for not knowing the exact jspwiki version on our site; I am not the admin, and I cannot for the life of me find where to get this information by browsing the wiki itself.)

On a page such as http://wiki.netbeans.org/wiki/view/AutoupdateAPI I would like to have not just

[org-netbeans-modules-autoupdate-services.zip]

but also

[jar:http://wiki.netbeans.org/wiki/attach/AutoupdateAPI/org-netbeans-modules-autoupdate-services.zip!/index.html]

so the contents can be browsed directly from Firefox. Unfortunately when I try that I get an error message:

No InterWiki reference defined in properties for Wiki called 'jar'!)

I'm not quite sure what that means but I guess jspwiki does not understand that the URL above should be used as is, because of the unusual protocol.
