Subject RE: OT?:Can't include .js file on jsp page controlled by front co ntro ller servlet
Date Mon, 12 Jan 2004 18:22:59 GMT
Also, if you're using an anchor tag that has "#" in it, then using
'onclick', change that to:

href=javascript:
 
The "#" will cause the page to reload, and because it's a JSP, you might
be invoking something you're not wanting to invoke. (like a login
check).
 
We had this exact problem when using mat kruse's calendar javascript
(because I think his examples use #, but for us it was causing
problems).

        Subject:        OT?:Can't include .js file on jsp page
controlled 
by front contro ller servlet


I may be getting in over my head here as I'm really not all that
familiar with patterns. And I'm not sure that the pattern has anything
to do with problem. But I have a controller servlet through which all
web requests 
must
pass. It has worked fine as is. Until I tried to include a .js file on a

jsp
page. In that case it seems to either print it out to page, rather than
execute it, or it tries to use requestDispatcher portion of controller
servlet to forward/include it. Normally the requestDispatcher forwards
request to the requested page after it checks to see if user is logged
in. But now it seems to go into an infinite loop when forwarding. And  I
guess it's trying to use requestDispather.include because the .js
resource is included via a "src='http:...' " request. I know that this
is a very vague question but I wonder if anyone has any clues as to
where the problem 
might
lie or what I can start experimenting with.
