RE: Struts Question.
Hi Leonard,
For your question,
< When it forwards to a tile what should happen and is there any
linkage you
can think I may be missing. >
You can associate a controller(Java code or Action) to your tile, which will
run
immediately before your Tile JSP page and put some debug statements to see
if
the tile is processed.
Regarding missing links, I don't think of any. But I see index_jsp in the
Exception stack.
So, I am guessing that you are invoking index.jsp, which is having a Link to
action
/skiptomain. I don't quite understand the flow of your application.
So, I am posting this email to Struts user mailing list so that someone can
understand
your questions and hopefully give some ideas.
