Re: WEB2 help needed - did build but no page display..?? Kinda working

[RP <rp...@earthlink.net>]

Got live results pages after I moved a jasper lib out of the way but 
keymatch does nothing - div id is there but nothing is in it....  I put 
the keymatch def in the tiles-def.xml but left the location path at the 
default which might be an issue as that is not the same as the plugin 
path.  I put the keymatch line in the search.jsp file but I'm not sure 
that is correct but the div shows up. Anyway - here is latest error:
