Description

I m using Struts-1.2.0 and Tomcat 4.1.30.
I have a link in my "index.jsp" that uses 'forward' attribute of <html:link> to
transfer to a page called "xyz.jsp".
For your reference the code snippet is as below:
---------------------------------------------
In index.jsp ->
<html:link forward="xyzForward"> XYZ Form </html:link>

In struts-config.xml ->
<global-forwards>
<forward name="xyzForward"
path="/xyz.jsp"/>
</global-forwards>
---------------------------------------
And i get the HTTP Status 500 Internal Server Error: The root cause is as
follows: (only the initial 4 lines is listed)

Note : With "href" and "action" attributes of <html:link> the index.jsp is
getting displayed but exception occurs while using "forward" and "page"
attributes.
