Creating URLs referencing a JSF application
by Bill-124
::
Rate this Message:
Hi all,
I've gotten a request for one of my JSF applications for users to be able to directly link to pages within the application. The application simply takes a bunch of form inputs and returns some images derived from these inputs...it doesn't require any 'state' information so it should be pretty straightforward. Is there a way to do this without having to manually create a GET type URL myself? I start doing this, but it became apparent that this would be very tedious... -Bill |

Hi Bill,
Do you mean you want to redirect to another pre-existing page as in: try { ExternalContext externalContext = getFacesContext().getExternalContext(); String pageURL = externalContext.getRequestContextPath() +"/faces/YourPage.jsp"; externalContext.redirect(pageURL); } catch(IOException ioe) { ioe.printStackTrace(System.out); System.out.println(ioe.toString()); } Or do you mean you want to load an image file based on what the users select?

Lets say you have 2 pulldowns, with id's "pd1" and "pd2" on a page
"page.jsp" for your website "www.example.com". If you create a form using these and submit then, there is no 'GET' type of url for them to bookmark, copy/paste. You'd simply be on the same page: http://www.example.com/page.jsp So I'm looking for something that will automatically create this URL for me like: http://www.example.com/page.jsp?pd1=selection1&pd2=selection2 On Thu, Jul 17, 2008 at 7:39 PM, Rick Fincher <rnf@...> wrote: > Hi Bill, > > Do you mean you want to redirect to another pre-existing page as in: > > try { > ExternalContext externalContext = > getFacesContext().getExternalContext(); > String pageURL = > externalContext.getRequestContextPath() +"/faces/YourPage.jsp"; > externalContext.redirect(pageURL); > } catch(IOException ioe) { > ioe.printStackTrace(System.out); > System.out.println(ioe.toString()); > } > > Or do you mean you want to load an image file based on what the users > select? > > Rick > > > Bill wrote: >> >> Hi all, >> >> I've gotten a request for one of my JSF applications for users to be >> able to directly link to pages within the application.

Anyone have any ideas? Am I not explaining this clearly?
I would think linking into a JSF application, with arguments in the URL, would be a pretty common usage...

I don't think i am understanding the question correctly; but , in
page.jsp , can you try 'response.sendRedirect("http://www.example.com?pd1=selection"); Alternatively, you could have a 'Create URL' button on the page that can construct the url and show it to the user. Of course, within a web application, one needs to be careful and ensure that a bookmarked page can be accessed independently. For instance, if the webapp requires a login, then when a user accesses a page directly with a set of parameters and has not logged in yet, the page should preferably show the login page to the user. regards, karthik Bill wrote: > Anyone have any ideas?

Hi Karthik,
This is exactly my point...Can JSF construct this URL already or do I have to do it manually and parse the arguments myself?? I started doing this manually, which is pretty easy for pulldowns and the like, but what happens when the users suddenly have JSF component Date fields to deal with? JSF handles the input as a Date class, so now I'd have to write a String to Date converter to convert a date in a String argument to a Date class in my code. I know this can be done...I just didn't want to have to do all this manual work which JSF is supposed to eliminate! -Bill On Fri, Jul 18, 2008 at 1:18 PM, Karthik <Karthikeyan.Rajeswaran@...> wrote: > I don't think i am understanding the question correctly; but , in page.jsp , > can you try 'response.sendRedirect("http://www.example.com?pd1=selection"); > > Alternatively, you could have a 'Create URL' button on the page that can > construct the url and show it to the user. > > Of course, within a web application, one needs to be careful and ensure > that a bookmarked page can be accessed independently.

I don't have a problem getting the query string. The problem is that
JSF does not create a query string for a form submission so there is no query string to get. As I posted in my earlier example, lets say I have 2 pulldowns "pd1" and "pd2". In "pd1" I select "optionA". In "pd2" I select "optionB" and submit the form. The application DOES NOT create a query string like "?pd1=optionA&pd2=optionB". If you look @ the URL @ the top of the browser, there is no query string. So there is no way that I know of to allow a user to revisit that submitted form page via a bookmark or direct link. Instead, every time they want to go to the page where pd1 = optionA and pd2 = optionB, they have to select the options in the pulldowns and submit the page. I don't want them to have to do this! I want to be able to give them a link that does this form them. Does this make sense?

Okay, I also know how to construct the URL myself ;)
I know how to get the values the user has submitted. I know how to create a URL from it. I also know how to read the parameters in from the URL, process them, and give the user the page they want. This to me, however, defeats the whole point of using JSF. JSF should do this for me, shouldn't it? What's the point of JSF if I have to get into the parameter parsing business?

Re: Creating URLs referencing a JSF application

Hash: SHA1 Bill, One of the drawbacks of JSF due to the built-in life cycle is that HTTP GETs are not directly supported, since application state is stored in the life cycle. I realize that your app does not need this state, but that doesn't matter, since JSF forces you to use this. If you need to use a GET, then you need some sort of intermediary servlet or something that takes the passed parameters, drops them into the JSF session, then redirects to the page that you want. Good luck, Bill Bill wrote: | Okay, I also know how to construct the URL myself ;) | | I know how to get the values the user has submitted. I know how to | create a URL from it.
