Now i have to first design the Application than have to lead the development process,i know most of the people here are invloved in designing process so my question from all of you are how can i start this process and i am clueless at the moment.the basic question are 1. Where to start 2 How to design Application i.e what needs to be taken care of, any tools that can help in designing or any other important points 3 How To redirect from Designing to Development (What should be taken care when we start Develpoment Process) I can explore furthure if i get some starting point so any help in this regard will be much appriciated Thanks in advance shekher

Re: Handling Browser Back/Forward Button in Struts2
Hi Hi Paweł,
i tried all the way in secure way
i implimented SSL and now my tomcat is running on port 8443 usinh https
protocol
i have created a custom interceptor for setting the header values
when user click logg off button this custom interceptor is working setting
the header values below is the code i am using
ActionContext context=invocation.getInvocationContext();
HttpServletResponse
response=(HttpServletResponse)context.get(StrutsStatics.HTTP_RESPONSE);
if(response!=null){
System.out.println("**setting
header**");
response.setHeader("Cache-Control", "must-revalidate");
response.setHeader("Cache-Control", "max-age=0");
response.setHeader("Pragma", "no-cache");//HTTP 1.1
response.setDateHeader ("Expires", 0); //prevents caching at
the proxy
response.setHeader("Cache-Control","no-store"); //HTTP 1.1
}
and on my logot message i have something like this
but still results are same
i can go back to secure page using browser back button
any idea why this is going on??
or do i need to set anything apart from this?

Re: Handling Browser Back/Forward Button in Struts2
Hi Paweł,
another way we can do this by using SSL
as we are dealing in secure zone so using SSL for this might be a good case.
the application i have seen so far who have dealt with this back/forward
button always using HTTPS protocol.
i am also diving in to this case study and will share the results

Re: Handling Browser Back/Forward Button in Struts2
using javascript is not a sure short solution
as i tested it throughly and javascript behaviour is not consistent throught
regarding setting header i did this i developed a custom interceptor which
is doing this
but again its not worked as expected.
i am still clueless how online banking application doing this trick
i am still on R&D mode for this if find anything will share it

Re: Handling Browser Back/Forward Button in Struts2
Is it possible that either i should only put these header in the logout
action
where i am removing the session and den redirecting the user to index page
something like this
HttpServletResponse response=null;
response=ServletActionContext.getResponse();
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Expires", "0");
or can we create a interceptor which can do this for all the request wheer
we want this feature??

Hi Paweł, thats true it only send request to server if i will refresh the page and for that i have already custom interceptor places which is checking the user object in session in order to confirm that the request is from authorized user but when i make use of back button it serve the page from the local chache,so the problem is related to client side more than that of server handling still trying to find a firm solution for it 2009/1/20 Paweł Wielgus > Hi Shekher, > first try this scenario: > 1. logout user > 2. back button - check for logs if action was fired > 3. refresh page - check for logs if action was fired > Most likely only the 3. will fire action because browser will serve > cached version of that page. > I was about to write that to deal with it You can use https scheme, > but i just got it checked and it's not true.

Re: Handling Browser Back/Forward Button in Struts2
i tried with javascript and it worked fine for me but still i believe that this is not the best solutions and as mentioned above if javascript is disabled the solution will no longer work so i have to look in to some other solution like setting pragma or cache-control will do? i am just removing the userobject from the session but not invalidating the session. i am not setting any header on response till now. Thanks Paweł for the detailed description, i will look in all the aspect as described by you and will share my findings. -shekher On 1/20/09, Nils-Helge Garli Hegvik wrote: > > Did you invalidate the session?

Handling Browser Back/Forward Button in Struts2
Hi All, in the process of developing application using struts 2.0.11, i came across the problem of handling browser back/forward button. This problem is occurring when we will logout the user.On Clicking the logout button we are currently removing the user from the session and it worked fine for us. After the successful logout process user will be redirected to the index page(which have the login field), but when user hits the browser back button he is getting himself there in the secure page even we have remove the user object from the session below is the code we are using for removing the user session.remove(BSConstant.USER); i am clueless where we are doing wrong , as we think we are having two points 1) Either the user is not getting removed from the session,but the chances are very less as for all other call after logout it is forcing the user to login first. 2) Back button handling is not there my question is, Is there any way in struts2 to handle browser back/forward button or do i need to use some other technique like setting response header any suggestion in this regard will be much appreciated. -s

I am planing to use interceptor for this but not sure how to plan this as using interceptor can not gurantee a robust authenticate mechanism what i planned is as below if user provide the valid information store the user object in the session scoped map and for all incoming request to secure region check the user object in the session using the interceptor,but will that be a robust approach??? any suggestion for this On Mon, Dec 15, 2008 at 5:55 PM, Andy Law wrote: > > > Shekher wrote: > > > > Hi All, > > > > We are developing an application based on Struts2 framework.

Application based Security
Hi All, We are developing an application based on Struts2 framework. We are on way to develop application based security so that the unauthorized user can not access the secure area,it needs the request to be from the authorized person.We can have the Below mentioed approach 1) For Secure area the user must be logged in to the ysystem and have authorization for accessing that 2) For every request coming to the secured region, we need to put the check if the user is a valid one or not. We cab think of the functionality which checks for the icoming request for its authentication and permits only authenticated request. I need your suggestion about the approach we can follow in struts2 so that we can achieve the above mentioed points and also maintenance and enterprise integration will be area of concern. IF any one have worked or working on similar area pleaes share his/her view how to achieve that here in struts2 Thanks in advance shekher

Creating struts2 form elements dynamically
Hi All, I need to create rows of struts2 form elements in my jsp on onclick event of a button. Whenever user clicks on the button, a new row of input types struts2 form elements should be created dynamically. I know creating simple html form elements using javascript but dont know how to do same for struts2 form elements. Any suggestion will be much appriciated! Thanks, Shekher

I want that when my action get called by YUI it must return a arrayList of string which i must be able to handle using the YUI. For this i took the help of example from YUI site and able to hit the action but my problem is that how can i get the access to the arraylist which my action is populating when its execute methos is called .below i m pasting the code from my action calss as well as the YUI code. Plaese let me know how can i get this arraylist in my YUI code * YUI CODE* var div = document.getElementById('container'); var handleSuccess = function(o){ alert("pass"); if(o.responseText !== undefined){ alert("test11"); div.innerHTML = "Transaction id: " + o.tId + " "; div.innerHTML += "HTTP status: " + o.status + " "; div.innerHTML += "Status code message: " + o.statusText + " "; div.innerHTML += "HTTP headers: "; div.innerHTML += "" + o.getAllResponseHeaders + "
Server response: " + o.getList().toString + " "; div.innerHTML += "Argument object: Object ( [foo] => " + o.argument.foo + " [bar] => " + o.argument.bar +" ) "; } } var handleFailure = function(o){ alert("fail"); YAHOO.log("The failure handler was called. tId: " + o.tId + ".", "info", "example"); if(o.responseText !== undefined){ div.innerHTML = ""; } } var callback = { success:handleSuccess, failure:handleFailure, argument: { foo:"foo", bar:"bar" } }; var sUrl = "YUITestAction.action"; function makeRequest(){ alert("test"); var request = YAHOO.util.Connect.asyncRequest('GET', sUrl, callback); } *MY ACTION CLASS* public class YUITestAction extends ActionSupport{ /** * */ private static final long serialVersionUID = 1926031204500756104L; ArrayList list=new ArrayList(); public String execute() throws Exception{ System.out.println("inside the execute method"); return SUCCESS; } public ArrayList getList(){ list.add("test1"); list.add("test2"); list.add("aum"); list.add("arun"); list.add("mannu"); list.add("umesh"); return list; } } any help in this regard is much appricaited --shekher
