URGENT: Get a parameter through the request of the onSubmit() method

Hi,
I am passing a parameter from a SimpleFormController to another SimpleFormController and i don't know why i cannot get it by the request of the onSubmit() method. The code will help you understand what i m trying to say
This is the first SimpleFormController that passes the parameter:
 
public class LoginController extends SimpleFormController
{
    public LoginController() 
    {   
    }
 
    private RSSUserService rssUserService;
    
    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, 
                                    BindException bindException) throws Exception 
    {
        RSSUser rssUser = (RSSUser) command;
        List<RSSUser> rssUsers = getRssUserService().login();
        Integer userId = null;
        for (int i = 0; i < rssUsers.size(); i++) 
        {
            if (rssUsers.get(i).getUsername().equals(rssUser.getUsername()) && rssUsers.get(i).getPassword().equals(rssUser.getPassword())) 
            {
                userId = rssUsers.get(i).getId();
            }
        }
        return new ModelAndView(getSuccessView(), "userId", userId);
    }
 
    public RSSUserService getRssUserService() {
        return rssUserService;
    }
 
    public void setRssUserService(RSSUserService rssUserService) {
        this.rssUserService = rssUserService;
    }
    
}
 
And the following controller is supposed to receive the parameter:
 
public class LoadRSSController extends SimpleFormController
{
    public LoadRSSController() 
    {
    }
         
    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException exception) throws Exception 
    {
        RSS rssObject = (RSS) command;       
        String url = rssObject.getUrl();
        Element eRSS = getXmlParsingService().getElement(url); 
        String idStr = request.getParameter("userId");
        Integer id = null;
        if (!idStr.equals(null)) 
        {
            id = Integer.parseInt(idStr);
        }
        RSSUser rssUser = getRssUserService().getRssUserById(id);
        RSS rss = getRssService().loadRSS(eRSS, url, rssUser);
        getRssItemService().loadRSSItems(eRSS, rss);
        getRssImageService().loadRSSImage(eRSS, rss);
        return new ModelAndView(getSuccessView());
    }
 
But after debugging the result of the request.getParameter("userId") is always null.

Can you please supply the view?
If you are expecting the value come back to another controller, then the view (i.e. the html page) must supply the form and input tags so that the requestParameter is sent back to the other controller.

i.e. the jsp page (or similar) should contain something like:

<form:form>
           <form:input path="userId" />
</form:form>

where the path depends on your mapping.

nick0306Author Commented:
The view of the login page looks like:
............
<form:form commandName="rssUsers" method="POST" action="login.htm">
<form:input path="username" size="40px"/>
<form:password path="password" size="40px"/>
<input type="submit" value="LOGIN"></input>
<form:errors id="wrongCredentials" />
</form:form>
............

And the view of the LoadRSS page looks like:

............
<form:form commandName="loadRSS" method="POST" action="loadRSS.htm">
<form:input path="url" size="80px"/>
<input type="submit" value="SAVE"></input>
<form:errors id="required.url"/>
 </form:form>
...........

Bear in mind that both are simpleFormControllers and they have a different commandClass, the first has RSSUsers object for class and the second has the RSS object for class

Thanks

I don't know if i am missing something here, but as far as i understand, the view should hold a field with name userID, so you can get it with request.getParameter. I don't see such a field in your views.

@objects: yes, it is passing it to the view, and the view passes it to the other controller. At least that's how i understand it.

KuldeepchaturvediCommented:
use

String idStr = request.getAttribute("userId");
instead of
String idStr = request.getParameter("userId");

remember once the request is created, you cant change the parameters in it, but you send around attributes associated with your request, thats what struts, or spring or other most framework use to send things around.

nick0306Author Commented:
Okay, the getAttribute is not working, and i tried to catch the parameter in the view but still is not working.
I changed the view of the loadRSS to:

.....................
 <c:catch var="userId" />
<form:form commandName="loadRSS" method="POST" action="loadRSS.htm">
<form:input path="url" size="80px"/>
<input type="submit" value="SAVE"></input>
<form:errors id="required.url"/>
 </form:form>
........................

and then in the controller: String idStr = request.getParameter("userId")
but i cannot understand how my variable in the jsp and from where will get its value..

objectsCommented:
its being passed to the success view of your login controller
are you passing it from that page to the load controller?

0
 
nick0306Author Commented:
Yes, i pass it from the login controller (getSuccessView(), "userId", userId) (btw successView = redirect to loadRSS) and then i catch it in my loadRSS.jsp like : <c:catch var="userId" />
and then in the loadRSSController when the onSubmit is called i get it like: String idStr = request.getParameter("userId");

Results:
Debugging shows that the parameter is passed alright but in the loadRSSController i get no value.
I don't know how to check my jsp if getting it

nick0306Author Commented:
Btw i tried to create a session in the login controller:
HttpSession session = request.getSession(true)
session.setAttribute("userId", userId);

And then get it from the loadRSSController:
request.getSession().getAttribute("userId");

but still doesn't work....

and to be honest i would prefer to have it in a session from which every controller of mine would have access
0
 
objectsCommented:
the map won't be passed in a redirect

not sure why the session isn't working, have you checked it is the same session

nick0306Author Commented:
No it's the first time i use spring mvc and i m a bit lost...
Can you please tell me how to check if it is the same?

objectsCommented:

KuldeepchaturvediCommented:
so if I understand it correctly..

your flow is
loginpage--> loginpage controller--> RSSpage--> RSScontroller.

there is one user id which you get hold of in Logincontroller and want to use it later in RSScontroller...

If that is the senario, your session should have worked (provided you are in the same webapp)..

Also in order to the userId in RSSController.. you need to have that value available in your RSSPage as well..

another way of doing this will be to introduce the UserId in your RSS Bean and then using

<form:input path="userId" />

on your RSSPage..

Also do one test to see if your userId is reaching to your RSSPage ( here I am assuming that RSSPage is the successview of login)..

add
<c:out value="${userId}"/>

& see if the user id is printed there
0
 
nick0306Author Commented:
No it is a different session id... the think is in the loadRSSController i use this line of code in the onSubmit() method: String idStr = (String) request.getSession().getAttribute("userId");
and i am not sure if it is the way to get the session we created in the login controller.

nick0306Author Commented:
Yes my flow is like that but i didn't really understood what exactly to do... My loadRSS bean has a command class of rss object and cannot enter the rss user object...

KuldeepchaturvediCommented:
Did you try the last item of my post?

i.e. putting the <c:out on your rss page?

nick0306Author Commented:
Just a simple question:  I create a session called session in the login controller and i put an attribute in it.
        HttpSession session = request.getSession(true);
        session.setAttribute("userId", userId);

How do i get access to that session and to its attributes from any other SimpleFormController in this web app?

nick0306Author Commented:
i tried now.. it stucks... it doesn't forward to the loadRSS when i submit from my login page...
The code is :
Login controller:
return new ModelAndView(getSuccessView(), "userId", userId); (which has a value is already tested)

LoadRSS.jsp:
......
 <c:catch var="userId" />
  <c:out value="${userId}" />
  <form:form commandName="loadRSS" method="POST" action="loadRSS.htm">
     URL: <form:input path="url" size="80px"/> <input type="submit" value="SAVE"></input> <form:errors id="required.url"/>
     <br></br>
    <a href='<c:url value="listRSSFeeds.htm"/>'>LIST ALL RSS FEEDS</a>
    <p class="one" align="center"><a href='<c:url value="logout.htm"/>'>Log out</a>
  </form:form>
  </body>
......

LoadRSS Controller:
    protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException exception) throws Exception
    {
        RSS rssObject = (RSS) command;      
        String url = rssObject.getUrl();
        Element eRSS = getXmlParsingService().getElement(url);
        String idStr = (String) request.getParameter("userId");
        Integer id = null;
        if (!idStr.equals(null))
        {
            id = Integer.parseInt(idStr);
        }
        RSSUser rssUser = getRssUserService().getRssUserById(id);
        RSS rss = getRssService().loadRSS(eRSS, url, rssUser);

nick0306Author Commented:
Sorry it was stucking because of a stupid test i did....
The code i wrote above doesn't print any value....
0
 
rbrindlCommented:
As i said before:
Want to get a parameter from a HTTP Request, that parameter needs to be present in that request.
For that you need to submit it in the HTML Form, i.e.  you need some field with the name userId, that holds the value.
In you would do that with a <form:input path="userId"/>.
That way, the HTTP request will contain a Parameter with name userId, and Spring MVC will take care that the value gets populated from your login Controller. ( By the return new ModelAndView(getSuccessView(), "userId", userId);)
If you don't want the value to be displayed, use a hidden field.(form:hidden instead of form:input )

getSession(true) creates a new session each time, so you will not be able to see the attribute you set in the previous session.
If you want to get the current session associated with the current request, use getSession(), then the session attribute approach should work, too.
But i suggest not using sessions if not necessary, as it reduces scalability.

nick0306Author Commented:
Okay i did that... I get the following error:
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'userId' available as request attribute
I suspect is because the commandClass of the bean loadRSS is rss and not rssUser

rbrindlCommented:
I am not a spring MVC specialist myself, only servlets and jsp. but please have a look at http://forum.springsource.org/archive/index.php/t-37068.html,
someone else is having the same issues.
It is about how spring handles models internally.
Please also see

In this code

<c:catch var="userId" />
  <c:out value="${userId}" />
  <form:form commandName="loadRSS" method="POST" action="loadRSS.htm">

    <p class="one" align="center"><a href='<c:url value="logout.htm"/>'>Log out</a>
  </form:form>
  </body>


remove the <c:catch var="userId" /> at the top, its declaring the variable and you will not see any value from c:out..

just use <c:out and let me know if it still comes as blank. ( it should not)

nick0306Author Commented:
I don't see anything in the page.. Is there another way to check its value?
0
 
nick0306Author Commented:
Something else which i find strange...
If i use handleRequestInternal() or formBackingObject() i can get the parameter from the request by using
request.getParameter("userId").
It's only the onSubmit() that does not get it...
And if i use handleRequestInternal then i cannot return a modelAndView without errors
0
 
KuldeepchaturvediCommented:
do right click view source and see if you see it there..


in spring when you send the model&view along with the name and object.. the jsp page def will have access to it..

so IF your logincontroller's success view is RSS page, I can see why you will not see the value of user id there..
0
 
KuldeepchaturvediCommented:
>>It's only the onSubmit() that does not get it...
And if i use handleRequestInternal then i cannot return a modelAndView without errors

its because onSumbit works with the commandbean that you have set up on your form.. until the variable is not there in the commandbean, you wont get to it.
0
 
nick0306Author Commented:
I saw the source and there is nothing there. It looks like i haven't entered the line:<c:out value.....

This is why i prefer to do it with a session so i can have access of that userId from all the controllers without the need to pass it all the time.
0
 
KuldeepchaturvediCommented:
implementing of the session should be working as long session is created once and used everywhere...

(i.e. using request.getSession(true)) at the start and then later on using request.getSession()....
I do not see a reason why it will not work unless there is something wrong\missing in spring config or setup files..

your xmls look alright, I dont see why a session will not work in this senario... tonight if I find time, I will try to see if I can work out a POC and see that the session is working as it should.

Bug is in your code:
 for (int i = 0; i < rssUsers.size(); i++)
        {
            if (rssUsers.get(i).getUsername().equals(rssUser.getUsername()) && rssUsers.get(i).getPassword().equals(rssUser.getPassword()))
            {
                userId = rssUsers.get(i).getId();
            }
        }
        return new ModelAndView(getSuccessView(), "userId", userId);

There is no break after matching the username. so the next loop again assigning null.
