[S2] Welcome Page as Action?
I'm sure this answer is trivial, but I can't figure how to do a
server-side forward to a Struts action from my welcome page
(index.jsp). Currently I have index.jsp "redirecting" the user, but I
would like to eliminate the roundtrip that a "redirect" imposes (I've
had complaints from mobile users). All my "forward" attempts give a
RequestURL file not found error. Has anyone done this? Google seems
to be unhelpful.
Currently this works but makes a roundtrip (index.jsp) :
<% response.sendRedirect("Login_show.action"); %>
Serverside attempts without success (index.jsp):
<jsp:forward page="Login_show.action"/>
<jsp:forward page="/Login_show.action"/>
<jsp:forward page="Login_show"/>
Using:
Struts 2.1.8
Tomcat 6.x
Apache 2.2
Many Thanks,
Burton

The problem is that many servlet containers won't even execute the filter
chain unless there's a match. And http://www.domain.com/path doesn't
inherently match index.html. So it looks to see if there is a file matching
the <welcome-file> ready to be dispatched. If so it starts the chain and
the filters get executed as you said. But without that empty file, many
servlet containers won't even get to the filter chain.

Haven't gotten it to work just yet. Just one of those minor
enhancements that you can't justify spending an entire day on. I'll
keep woroking at it though. Thanks all for your input and knowledge.

Hi
I put these in my project and its working for me.
I created a blank file called welcome.
In struts.xml
<package name="default" namespace="/" extends="struts-default">
<default-action-ref name="welcome"/>
<action name="welcome" class="com.upasana.WelcomeAction">
<result name="SUCCESS">WelcomePage.jsp</result>
</action>
</package>
In web.xml
<welcome-file-list>
<welcome-file>welcome</welcome-file>
</welcome-file-list>
Thanks and Regards

How'd it go when you put an empty default.action file in the directory?

Re: [S2] Welcome Page as Action?

I'm not sure the default action solves the problem.
I am put this in my struts.xml file:
<!-- Set the default action to Login_show -->
<default-action-ref name="Login_show" />
It appears that it only loads Login_show if a user types in an
*.action file. For example:
URL: http://www.mydomain.com/package/DOESNOTEXIST.action
Result: http://www.mydomain.com/package/Login_show.action
URL: http://www.mydomain.com/package/
Result: Simply loads the index.jsp file (I believe it doesn't route
through Struts because it doesn't match a "url-pattern" for the struts
filter). And if I put a <jsp:forward name="Login_show.action"/> in
index.jsp - I still get URL not found as before.
How are you getting the user from www.mydomain.com ->
www.mydomain.com/package/default.action using this method? I think I
am missing a step.

Struts runs in a filter that applies to requests that come through, so
the welcome file in web.xml doesn't matter.

I want to do the same thing but I didn't get you clear Brian.
If we follow your solution then Could you please explain little in brief
that how web.xml know about struts default action?
What should we put in web.xml for welcome file?

Add a default action in your struts xml. It's what we're doing in our
Struts app where I work.
<package name="foo">
<default-action-ref name="welcome"/>
<action name="welcome" class="com.example.WelcomeAction">
<result name="success">welcome.jsp</result>
</action>
</package>

Re: [S2] Welcome Page as Action?
Posted by Chris Pratt <th...@gmail.com>.
I'm not sure if this will work everywhere, but it works in Resin. If
you set your <welcome-file> to index.action and put an empty (ie 0
length) file named index.action in the root directory of your war
file. When the server gets the request, it first checks to see if the
request matches a known resource, if not it checks the directory for a
file matching specified welcome-file. If it finds one, things proceed
as usual and struts gets the request to process and will naturally go
to your index.jsp file to fulfil the request.
