JSF Request dispatching in JSF2.

Hi,
I get an unexpected error when dispatching a request.
try {
     HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
     HttpServletResponse response = (HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
     ((ServletContext) FacesContext.getCurrentInstance()
               .getExternalContext().getContext()).getRequestDispatcher(
               "/xhtml/com/easypaygroup/global/view/configuration/parameter/searchparameter.xhtml").forward(request, response);
} catch (Exception e) {
     handlePropertyException(e);
}exception:

This one works
//forward JSF request
UIViewRoot viewRoot = facesContext.getApplication().getViewHandler().createView(facesContext, lastHistory.getUrl());
facesContext.setViewRoot(viewRoot);
facesContext.renderResponse();

Nested request dispatches when using RequestDispatcher in a Button action

Hi all,
I am new to JSF so I am probably missing something very simple, please help:
The test case is simple: I created one visual web page with one button and one normal JSP file(named test.jsp) using Netbeans 5.5 with visual web pack on Sun Application Server 9 PE. The code action for the button is as follows:
public String button1_action() throws Exception
        ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
        HttpServletRequest request = (HttpServletRequest) context.getRequest();
        HttpServletResponse response = (HttpServletResponse) context.getResponse();
        RequestDispatcher dispatcher = request.getRequestDispatcher("test.jsp");
        dispatcher.forward(request,response);
        return null;
    }Once the JSF page is loaded and the button is clicked, this exception occurs:
ApplicationDispatcher[WebApplication1] Servlet.service() for servlet Faces Servlet threw exception
javax.servlet.ServletException: WEB2651: Exceeded maximum depth for nested request dispatches: 20
at org.apache.catalina.core.ApplicationDispatcher.doInvoke(ApplicationDispatcher.java:837)
at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:697)
at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:532)
at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:465)
at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:353)
at webapplication1.Page1.button1_action(Page1.java:242)
Can anyone provide any advice on how to resolve this issue?

Hi Rachel,
As per the Servlet2.3 Javadoc:
The pathname must begin with a "/" and is interpreted as relative to the current context root.
If you make that change and include the complete path, then it would work fine.
Ex:
If your context looks like http://my.company.com/webapp1/ and if you were to have your forwardPortlet.jsp in a directory like:
webapp1
  |
  |-> htdocs
         |
         |-> forwardPortlet.jsp
then, your code would look like;
RequestDiscpatcher d = request.getRequestDispatcher("/htdocs/forwardPortlet.jsp");
HTH,
thanks,
harsha

Query Strings in Request Dispatcher Paths (PLT.16.1.1)

I'm having trouble using query strings in a request dispatcher include to a servlet.
I'm spitting debug out, and it looks like I'm calling:
PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher("/myServlet?myparam=myparamValue");
And myparam isn't being set for myServlet.
The same URL ("http://myhost:myport/myPortal/myServlet?mayparam=mayparamValue)
runs fine standalone....

I'm not sure of the exact dates (either this month or the next). But
JSR168 will be supported in the service pack.

There is a known bug in WLS's servlet container that results in this

Can you tell me when it will be available?
Also, when will JSR-168 v1.0 be supported?

Problem with Non JSF Request to JSF Page

Hi All,
I am working on dynamic controls generation based on the request come from non jsf page
For the first request, pageworks perfectly. but when we go for second request, it is not rendering and I am getting same old page.
What I have identified is if I have 2 pages as JSF, application is not giving any problem.
For this I have written small test application contains both JSF pages only.
page1 contains 3 submit buttons.
When submit buttons are clicked based on the request, I get, am able to see the dynamic controls.
SO there is no problem with JSF PAGE to JSF Page Communication
Now I have done some changes in First JSF page. Instead of submitting directly I am submitting the page through JavaScript which is nonb JSF request. There I am facing the problem and based on requested qaction I am not able to see correct rendered page based on the requested action.
Any Idea why it is giving problem for non JSF requests??
Thanks
Sudhakar

For Your Convenience in understanding the problem
I am pasting entire test code
Page 1 -- (here page2 is Page1 and Page1 is page2 - some naming convention errors :) )

Urgent, creating xml files dynamically, request dispatcher problem

hi all,
Problem 1:
There is a problem we are facing, while request dispatching.
The files CBECBC.XML & CBECBC_Envelop.XML,
both xml files. These files are created on request from the user, dynamically, and displayed on the browser,
by including them in a jsp page.
Here we face a problem when they are to be included into the jsp page.
The error is the following :
//////// Error ////////
Could not find request dispatcher for the url CBECBC.xml
Could not find request dispatcher for the url CBECBC_Envelop.xml
The created files are stored in the "d:\pstudio35\desks\bank\BankWeb\".
We are using " <jsp:include page="...."/> " (dynamic jsp include tag), to include the xml files.
Problem 2:
And could you just let me know how to include a xml file in a jsp file,
so that the xml file is displayed in the exact format of xml(with the tags).
I am using Pramati Studio 3.5
Its urgent!!!
Regards,
Deepa Datar

problem 2:
either translate all < en > into < and > or display the XML in a textarea

Request dispatcher null

          The forward code we have is like
          public void forward(String url, HttpServletRequest request,
          HttpServletResponse response)
          throws ServletException, IOException
          RequestDispatcher dispatcher = getServletConfig().getServletContext().getRequestDispatcher(url);
          dispatcher.forward(request, response);
          My question is:
          As per the documents
          The pathname must begin with a "/" and is interpreted as relative to the current
          context root.
          if my URL is "http://www.abcz.com/<somepage>
          request dispatcher is null? and on one server (say A) that is a problem but other
          server(say B) when given the full URL behaves ok.
          on server A I am getting a null pointer exception , which on tracing happens to
          be the request dispatcher is null.(If http://www.abcz.com/<somepage> is URL) but
          no null pointer exception if url is "/<somepage>"
          On B its behaving fine when given the "http://www.abcz.com/<somepage> " as URL
          to the method.
          Both server A and B are running wl6. Is the difference in service pack cause of
          the problem?
          Internally does wl6 parses the URL to find a relative URL?
          Any help will be greatly appreciated.
          Thanks
          Rumpa


And the reason for that is, RequestDispatcher is per application
          scope. And RequestDispatcher comes from the ServletContext which is
          the current application scope. So it has to be relative url. If you
          need to forward to an absolute url, you can use sendRedirect instead.

Request dispatch problem

To all
The problem is that my request dispatching is not forwarding the request and I haven't got a clue why. I have a upload servlet which is working fine as it parses the request and the forwards you to the same jsp page or the next jsp page according to what values it extracts. However I have set up a bean to display the contentType() of each request which is sent to it from the jsp pages, however nothing is displayed when the request is forwarded from the upload servlet. this is what is happening .....
public class upload extends HttpServlet {
public void doPost( HttpServletRequest req, HttpServletResponse res ) throws ServletException, IOException {
HttpServletRequest request = _req;
HttpServletResponse response = _res;
parseMultiForm pMF = new parseMultiForm( _req );
Hashtable values = new Hashtable();
String param;
while ( ( param = pMF.getNextParameter()) != null) {
String value = pMF.getParameter();
values.put(param, value);
if (values.containsKey("submit")) {
String url = (String) values.get("reload");
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/" + url);
dispatcher.forward(request, response);
if (values.containsKey("continue")) {
String url = (String) values.get("next");
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/" + url);
dispatcher.forward(request, response);
The above servlet forwards the request to a jsp which does the following....
<jsp:useBean id="info" scope="session" class="InfoBean" />
<jsp:setProperty name="info" property="request" value="<%= request %>" />
However infoBean does not receive anything when the request is forwarded from the servlet??
Can anyone see anything obviously wrong?? is it to do with the JSP asking for the <%= request> and not receiving it because the request dispatcher has altered it in some way?
Thanks in advance anyone
Andy.

I have exactly the same problem. I can�t make the servlet pass the request object to the target jsp.
Try not changing the request nor the response. Unfortunatelly due to the kind of job i do inside my servlet there's no way i can't touch the request. So if you can make it work with mi advice please let me know.

Unable to use Request Dispatcher; Duke $ Post;

I am using a Controller Servlet to transfer control to a JSP using Request Dispatcher within doPost()
RequestDispatcher rd;
rd=req.getRequestDispatcher(URL);
rd.forward(req,resp);
I am seting a request object
req.setAttribute("XXX",obj.func());
prior to the Redirect;
The page gets redirected to a JSP. I am unable to access req object in there.
if i use
String XXX = req.getAttribute("XXX");
i get an error in the jsp as
"req cannot be resolved"
Do i need to import some directives? Please Reply

The page gets redirected to a JSP. I am unable to
access req object in there.
if i use
String XXX = req.getAttribute("XXX");
i get an error in the jsp as
"req cannot be resolved"
Do i need to import some directives? Please ReplyThat's simple. Your req (which is the HttpServletRequest object) in the servlet becomes request in the JSP. That's always there. The compiler would not recognize req
Use request.getAttribute("XXX"); in JSP

Request dispatcher between 2 servers

dear sear:
can i use request dispatcher to go from one servers to another whith the same session.
thanks,
hamdi.

Nope, Request dispatcher works with in its servlet container.
May be you can you Request.sendRedirect()..
not sure.

Passing Attribute in Request Dispatcher

Hi,
I am using servlet#1 to pass the value of an Attribute to servlet#2
servlet #1 code
ServletContext sc = getServletContext();
request.setAttribute("name",value);
RequestDispatcher rd = sc.getRequestDispatcher(url);
rd.forward(request, response);
servlet #2 code
ServletContext sc = getServletContext();
String string = (String) sc.getAttribute("name");
when I run servlet #1 request dispatcher forwards request and response to servlet #2 but the Attribute value is not passed along
what am I missing ?
thanks VERY much for your response in advance and past responses !!
Rick

Hi rickdd,
In servlet #2 you should get the value from
servlet's Request object rather than ServletContext,
because parameter is set with Request Object not with
ServletContext.
So modifiy the code as given below...
     /* Parameter is passed with servlet's Request Object.
      * So Next line needs to be commented.
     //ServletContext sc = getServletContext();
     //Here get the value from servlet's Request Object
     String string = request.getAttribute("name");
   This will work.

Request dispatcher method--help needs

Hi,
I used request dispatcher method to redirect the from one servlet to another servlet.But when i use get method it is functioning well.
But when i use post method it is giving error...
I need to use post method...
How can it possible..
Thanks,
Babu B

you have code for request.RequestDispatcher.forward(""); method in both doPost and
doGet methods for the servlet. However your initial form is not set with method
to POST.
By default the method is GET and it will execute code in doGet and not code in
doPost() method. so in your first form use method as POST instead of keeping
it to default i.e no method specified.
let me know where are you using RequestDispatcher.

Request dispatcher vs redirect

if there is the request dispatcher already,
          then what exactly is the point of having response.sendRedirect(url)
          is there any situation in which one should use sendRedirect over using the
          request dispatcher?
          thanks

          1. You cannot forward to a file thats not this server. But you can use
          sendRedirect
          2. By using sendRedirect you are also informing browser regarding change of the
          location.
          3. When you post data to server and use of browser relaod posts data back to
          server in case of dispatcher.

Can Request Dispatcher include 2 Jsp's ??

HI ...
can Request Dispatcher include 2 Jsp's.....in which
second Jsp is accessing some parameters from First Jsp....
From my point of view , both jsp's are get compiled seperately hence
2nd Jsp is not getting parameters from 1st Jsp..
Any other way to solve this problem....???
rdTop = sc.getRequestDispatcher("/Reports/top.jsp");
rdTop.include(req,res);
rd1 = sc.getRequestDispatcher("/Reports/MenuTrail.jsp");
rd1.include(req,res);
Thanks

No Actually ,i am using include becoz Top .jsp includes our menu,& menu trail also contains our menu...i am displaying both Jsp's thru
servlet hence i have used Include.....
Thanks

What is the best way to Process non-JSF request??

I am engaged in new project using JSF.
We came across the serious problem that there is no-way
to let JSF execute action method of managed bean at the
first request.
That is because, JSF gets method binding information only
from pre-displayed UIComponent, it seems impossible to
let JSF know about the method binding info when they receive
the request from external system, or from non-JSF pages i n the
same system.
I get to two ways to solve this problem.
1. develop a custom-servlet
The tasks of the custom servlet is,
- receive a request from external system or non-JSF pages.
- get managed bean and execute it's action method.
- get next page info
- dispatch to next page through FacesServlet
2. use bridge-JSF page as a intermediation
This is kind of last resort.
As I described above, JSF can get method binding info, only
from components of pre-displayed pages.
So, I use bridge -JSF page to let it work as a intermediation.
It displays nothing, just click the commandbutton automatica
lly(by JavaScript).
Of-cource, I prefer 1 to 2.
Codes below are custom servlet sample , I made.
Pls let me know if it's ok or not.
thanks
public class FESFacesServlet extends HttpServlet{
    public void doPost(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {

                                        FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
        Lifecycle lifecycle = lFactory
                                .getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);
        FacesContextFactory fcFactory = (FacesContextFactory)
                                            FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
        FacesContext facesContext = fcFactory.getFacesContext(getServletContext(), request, response,lifecycle);
        Application application = facesContext.getApplication();
/* set from-view-id */
        ViewHandler viewHandler = application.getViewHandler();
        String viewId = request.getParameter("fromviewid");
        UIViewRoot view = viewHandler.createView(facesContext, viewId);
        facesContext.setViewRoot(view);
/* find managed bean and execute it's action method */
        ManagedBeanBase managedBean = (ManagedBeanBase)application.getVariableResolver().
                                                resolveVariable(facesContext, request.getParameter("command"));
        String outCome = managedBean.start();
/* look for next page info */
        NavigationHandler navigationHandler = application.getNavigationHandler();
        navigationHandler.handleNavigation(facesContext, null, outCome);
/* dispatch to next page throw FacesServlet */
        facesContext.getExternalContext().dispatch("/faces" + facesContext.getViewRoot().getViewId());
        facesContext.release();
    public void doGet(HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException {
        this.doPost(request,response);
-

the common approach is kind of like your number 2)
but you dont need a commandButton
just have your first page redirect to your start page
e.g.
index.html
<html>
<head>
<!�redirect to startPage -->
<meta http-equiv="Refresh" content= "0; URL=index.faces"/>
<title>Start Web Application</title>
</head>
<body>
<p>Please wait for the web application to start.</p>
</body>
</html>

http://groundside.com/blog/DuncanMills.php?title=j2ee_security_a_jsf_based_login_form&more=1&c=1&tb=1&pb=1
I have added this code in login.java
     ExternalContext ectx =    FacesContext.getCurrentInstance().getExternalContext();
     HttpServletRequest request =    (HttpServletRequest)ectx.getRequest();
     HttpServletResponse response =    (HttpServletResponse)ectx.getResponse();
     RequestDispatcher dispatcher =   request.getRequestDispatcher("loginnew.jspx");
RequestDispatcher dispatcher =   request.getRequestDispatcher("j_security_check");
    request.setAttribute("j_username", username);
    request.setAttribute("j_password", password);
     dispatcher.forward(request,response);
When it tries to execute dispatch statement, it goes in an infinite loop and finally gets me a stack overflow error and also in the cosole it prints series of exceptions like
ActionListenerImpl><processAction> javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: Could not initialize class oracle.adf.controller.ControllerException
javax.faces.el.EvaluationException: javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: Could not initialize class oracle.adf.controller.ControllerExceptionI have to validate the user against database hence i created a login.jspx with a backing bean so that i can access the username and password and validate the credentials against db and redirect user to the appropriate page.
The functionality i want to implement is very simple but i just cant get it to work using adf security.
any help is highly appreciated.
thanks

Hi Pedja,
Thanks for the prompt reply.
I have been following the link you mentioned to create ADF security and successfully implementedthe first part where if i directly give any internal page url it redirects me back to login page.
Instead of using weblogic-sql authenticator, i wanted to manually authenticate the user in loginbean.java where i check the username passowrd against the db.
I had also implemented the method to access username,password mentioned in the following thread
Re: ADF security on my jspx page as login page
Insted of using authentication.login, i am calling the db method to do the validation.
The thing is after my db validation it does redirect me to the success page(menu.jspx). but when i click links on menu.jspx it redirects me back to login page.
so i understand that user is not yet set in the session.
I am stuck at the point how do i code the login.jspx, currently my login.jspx does not have any j_security_check and i think this is what is creating the problem.
while searching for adding jsecurity in jspx i landed on the blog of 2006 and started using that.
Can you please point me to some link which explains how to code login.jspx , i have been trying hard for couple of days.
Thanks again
