[Q] struts:link with forward attribute on WebLogic 6.0
I try to forward the request in a jsp page as follows: <%@ page language="java" %> <%@ taglib uri="/WEB-INF/struts.tld" prefix="struts" %> I have the "ibohome" defined in the action.xml as follows, However, I got the following exception when I am trying to run it (I got the same exception if I replace "success" with "ibohome").

RE: [Q] struts:link with forward attribute on WebLogic 6.0
Do you have a quick answer to my last question in my previous note? The question is included below. What I am trying to do is that when the index.html or index.jsp is invoked, it will forward the request to my main page without user to type anything. The main page is a jsp which will be invoked by one of the actions I will write. (I think what I need is to directly invoke the Struts servlet with certain parameters without using struts:link). Any other approach I can take. Thanks, Zhiyong -Original Message- From: Craig R.

What is the syntax? I tried,
None of them work. ("generic" is a action defined in the action.xml).

If you want to forward totally transparently, doesn't do
the
trick?

It should be a context-relative path to your action or page. For example, if
you use the normal style of mapping the Struts servlet to "*.do", it would be

think it was in Struts 0.5.

That fixed problem. I actually need to add extra path to "/generic.do",
but the idea is correct.
