I am trying to integrate Wicket (1.5.16) with the "Single Sign-On". In this process, IdP posts a bunch of attributes back to the Wicket application using HTTP POST.
If I use , it looks for life cycle and also adds some numbers to the form, etc. I am looking for the following solution,
1) Create a Servlet/Some Wicket class which can receive the POST requests.
2) If SAML authentication is successful, forward to a private Internal .
Please let me know if you have any submissions.
You can wrap Wicket in another Servlet Filter. This way your Filter will receive the request first and may decide whether to process it or pass it to Wicket.
To accomplish this you just need to define your <filter> above/before Wicket's filter/servlet in web.xml.

I've seen plenty of servlet filters in my time for doing all kinds of things but always on REQUEST never anything else. Does anyone have any use cases or examples of why it might be useful to write a servlet filter for another dispatcherType, other than REQUEST?
The DispatcherTypes as in javax.servlet package.
public enum DispatcherType {
FORWARD, INCLUDE, REQUEST, ASYNC, ERROR
}
Well the names are rather self-explaining. The REQUEST is indeed the most often used one and it's applied on the incoming request chain. Here is when you may need to use the others (because the REQUEST only dispatched filters will not be applied):
FORWARD - if you want to filter request/response when one servlet forwards the request to another servlet. Often this is used when a servlet forwards to a JSP page.
INCLUDE - if you want to filter request/response when one servlet calls another servlet in order to include it's response in the own response. Often this is used when a JSP page includes JSP page.
ASYNC - This is something I personally never used but AFAIK it's needed to be able to filter the asynchronous requests introduced in Servlet 3 spec
ERROR - if you want to filter request/response when the servlet call results in error.
See https://sling.apache.org/documentation/the-sling-engine/filters.html#filter-chains for some more details.
Sorry friends if this question is very easy but i am confuse i unable to find out solution.
As we all know in spring MVC framework we create controller which will handle multiple request from same page using #requestmapping annotation.
but same thing i want to do in servlet how can i do ?
Suppose i have a jsp which which will contain a jqgrid,and two forms i want to use only one servlet to load the data into jqgrid and that servlet only will handle request from both the form . Since we have only doGet and doPost in servlet how one servlet fulfill all three request. Hope you understand my question if you have and link where i get sample or and tutorial link plz reply me
Well, the only easy way to do this would be to use a request parameter to control how the processing happens.
In a very basic example, you may have something like a requestType value that gets passed as either part of the query string or the request body. You would assign values of 1-3 (or 0-2) with each value indicating a different type of request. Your servlet would then parse the request accordingly.
This actually is how the DispatcherServlet in SpringMVC works. There's only one servlet class instance and when a request comes in, it examines the query string along with other parts of the request to determine which controller should handle the request.
I want to secure (temporarily) my application by create front page with captcha and simple form. I suppose Spring Security is too complicated for this task. How can I catch all requests and check if some attribute in session is set? If it is set then all these #RequestMapping methods should be executed, otherwise redirect to one front page.
Have a handler interceptor defined and applied to all the handlers. The example in that link shows you also how to perform the redirect. Also check the mvc:interceptors for the Spring 3 - like configuration.
You can simply configure a Filter for this
I want to filter all requests to my web application through my "SecurityFilter" which checks that a session variable "authToken" is valid. The problem is that in order to get this token you need to hit the "AuthServlet" which is at /auth.
I need to filter all servlets except the /auth servlet with my "SecurityFilter". How can I do this via guice-servlet?
I thought of trying to no avail...
filterRegex("!((.)*auth(.)*)").through(PortSecurityFilter.class);
^((?!/authorize).)*$ worked.
i want a mechanism in my web app as described below:
user will enter mydomain.com/CompanyName , depending upon the CompanyNameit will show its logo and its customized page, and i will take that parsed parameter in session again upon each request i will compare the parsed CompanyName and one stored in session , and if they matched then application will show the requested page with user's data.else it will be redirected to login page.
and the main thing is i want this thing in JSF arch.
i tried taking a servlet that will resolve all request and it will parse and then will dispatch the request to prefered servlet,but problem is it goes in loop as again it resolves to the same controller servlet,
You can do this via a phase listener. You can define a global one in faces-config.xml (or using annotations, if JSF 2.0 is used)
<lifecycle>
<phase-listener>com.yourcompany.CompanyPhaseListener</phase-listener>
</lifecycle>
There you have access to the FacesContext, from which you can obtain the current request URI. Parse it and store the appropriate attributes in the request, which you can later read on your pages.
The phase listener is executed on the specified phase(s), and perhaps you should choose RENDER_RESPONSE

Use a Filter instead. It by default doesn't listen on forwarded requests, so you won't get an infinite loop on forwarding.
