causing Exception in JSP
I'm new to JSP and Struts. I'm trying to learn from a book I bought, but I'm
getting an error on my index.jsp page. Not sure what the problem is and I've
spent all day trying to figure it out. Any help is appreciated.

I believe I found the source of my problems. I was flipping back and forth
between the mailreader example and the app I was working on when something
caught my eye in the web.xml file.
Here's what the mailreader had for <servlet-class> in the servlet config:
org.apache.struts.action.ActionServlet
Here's what I had in my app for <servlet-class> in the servlet config:

I believe your global forward should point onto /search.do (which is the
ActionMapping whose path is defined as "/search" further down in your
struts-config.xml:
<global-forwards>
<forward name="search" path="/search.do"/>
</global-forwards>
Everything else in your struts-config-xml seems to be fine. Does that help?

That didn't work. I did however take a closer look at my struts-config.xml. I
happened to find in my action mapping my type was
"com.jamesholmes.minihr/SearchAction", I replace the "/" with "." and now it
doesn't give me JSP exception, now it just gives me:

I believe your global forward should point onto /search.do (which is the
ActionMapping whose path is defined as "/search" further down in your
struts-config.xml:
<global-forwards>
<forward name="search" path="/search.do"/>
</global-forwards>
Everything else in your struts-config-xml seems to be fine. Does that help?

I just tried putting the slash before search in my forward attribute as you
mentioned, but I got the same error. Here's my struts-config.xml.

Hi Patrick,
Have you tried putting a slash:
<html:link forward="/search">
If that doesn't solve your problem, I suspect that you would need to post
the content of your struts-config.xml file...
Good luck!
