Thanks to you
and also thanks to kedar for great logic
but i dont know why postLoginURL remains empty in my case
so i have choose way of session it works fine right now but i dont know
about future problems of it
i have done like this
Inside interceptor i wrote
------------------------
if (!isAuthenticated) {
String urlGoingTo = actionInvocation.getProxy().getNamespace()+"/"+
actionInvocation.getProxy().getActionName()+".do";
session.put( "actionurl", urlGoingTo);
struts.xml
----------------------
<action name="Login_*" method="{1}" class="authentic.Login">
<result name="input">/Login.jsp</result>
<result name="cancel" type="redirect-action">Welcome</result>
<result type="redirect-action">MainMenu</result>
<result name="redirect"
type="redirect">${session.actionurl}</result>
<interceptor-ref name="guest"/>
</action>
-------------------
Login.java
-------------
if(session.get("actionurl") != null && !session.get("actionurl").equals(""))
{
return "redirect";
}
return SUCCESS;
--------
Thanks

RE: about current action name acsess

it works now
i made just this change in struts.xml
first i wrote
<global-results>
<result name="login" type="redirect-action">Login_input</result>
</global-results>
now it works fine when i write
<global-results>
<result name="login" type="chain">
Login_input
${postLoginURL}
</result>
</global-results>
something i could understand is because of result type chain inspite of
redirect action
is is true?

Well, I'm not sure why the %{#postLoginURL} did not work for you.
Glad that you got it working using session as storage.
The issues in using session as storage for postLoginURL are pretty minor in
nature:
1) un-authenticated user tries to access privileged URL, say
/privileged.action, he is sent to login screen, but he navigates out to some
other page and then from elsewhere in the site clicks on "Login" link. In
such case, after successful login he should be taken to home page as he has
initiated the login. But using session to store postLoginURL, user will be
sent to the /privileged.action.
2) user has two browser windows open, in window-1 he tries to access
/privileged-1.action is taken to login page, he does not immediately
complete the login. In window-2, he tries to access /privileged-2.action is
taken to login page, does not complete the login here. He returns to
window-1 and completes the login. He returns to window-1 and completes the
login. Here he should be taken to /privileged-1.action but actually will be
taken to /previlged-2.action
3) user tries to access /previlged.action, is taken to login page, but user
goes for lunch break, completes the login after lunch break. He is taken to
home page as his session is gone by the time he completes the login.
In fact, there is one issue with the solution I was using.
It would not take user to postLoginURL if user makes a mistake in first
login attempt but succeeds second time. Following changes to the solution
given earlier will correct this issue:
=================
struts.xml
<global-results>
<result name="login" type="chain">
<param name="actionName">login_input</param>
<param name="postLoginURL">${postLoginURL}</param>
</result>
</global-results>
login.jsp
<s:form label="Login" action="login">
<s:textfield key="loginId" />
<s:password key="password" />
<s:hidden name="postLoginURL" value="%{postLoginURL}"></s:hidden>
<s:submit />
</s:form>
============
Regards,
Kedar

After Inspecting postLoginURL I have found that entry of ctx hashtable
PostLoginURL remains in it but it can not come at Login.java(getter and
setter of PostLoginURL)
so i think some thing missing in it or wrong at login.jsp so value can not
come after submitting form at login.java

Kedar's example looks really good. Double-check that you've done
everything he's asked
Put a breakpoint inside your interceptor to see if postLoginURL is being
built correctly.
Assist your debugging by forcing it to return redirect every time.
I would have thought the hidden field should have been this though:
<s:hidden name="postLoginURL" value="%{postLoginURL}"></s:hidden>
(I have removed the # as # implies a root object rather than a property of the action)

i think i can not get any value of %{#postLoginURL}
what actually happens i dont know
how can i check value of postLoginURL is available upto login.jsp
or not
can i use
<%=ActionContext.getContext().getParameters()) %>
but it shows null at login.jsp

Have you put
<s:hidden name="postLoginURL" value="%{#postLoginURL}"></s:hidden>
in login form?
Check the source of rendered login page to see if this hidden input is
properly set to the URL we want to redirect.

Kedar

When you are directing the user to login page, you need to 'remember' the
action (rather URL) he was invoking. This needs to be made available to
Login action so that on successful login user can be redirected to the page
he was originally trying to access.
One of the ways to remember the original URL is to store it in session. But
there are certain issues with this approach. I prefer passing around the
original URL to login form and then to Login action.
public class AuthenticationInterceptor implements Interceptor {
public String intercept(final ActionInvocation actionInvocation)
throws Exception {
......
if (!isAuthenticated) {
final ActionContext ctx = actionInvocation.getInvocationContext();
final HttpServletRequest request = (HttpServletRequest) ctx
.get(StrutsStatics.HTTP_REQUEST);
if (request != null) {
StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
requestURL.append("?").append(request.getQueryString());
}
ctx.put("postLoginURL", requestURL.toString());
}
return Action.LOGIN;

How would you define 'current action' in the context of a configuration
file? Can you explain what you're trying to achieve?
