javascript in template causing problems
Any idea why this little bit of javascript would cause a problem?
I'm getting "cannot find servlet class graphics" errors unless I remove
this image rollover javascript from my template.
stack trace below..
Thanks,
Ken Anderson

Re: javascript in template causing problems
Posted by Ken Anderson <ka...@pacific.net>.
Okay, so it's not a template parsing thing, it's a tomcat thing.
I haven't seen this before. Seems odd that I can insert other broken
image urls into a template and they don't cause a problem, but doing so
with javascript does?
Thanks.

Re: javascript in template causing problems
Posted by Gabriel Sidler <si...@teamup.ch>.
Ken,
Tomcat "thinks" that it should invoke a servlet "graphics" but it
cannot find a corresponding class.
The cause is likely an incorrect URL for the graphics files in
your Javascript. Make sure that the path for those graphics file
is correct. Check the access log of your Tomcat installation to
find out what the browser really is requesting.
Hope that helps
Gabe
