JSF and links with parameters to restore jsf page state

Hi,
I've been developing a forum using JSF. It's going to be something similar to the one we are just using.
If a user, while browsing forum, find something interesting he should have a possiblity to copy URL form his browser and give it to his friend.
The URL should contain all necesary parameters to restore a same view (a subpage of a forum etc) a first user had. What's best approach to do it ?
Say, I have a few AJAX components on a forum page, how can I restore their states ? What's even more interesting how can I generate add parameters to URL in a browser ?
I've found a good solution for my problem:
[http://ocpsoft.com/prettyfaces/]
"PrettyFaces is an OpenSource extension with enhanced support for +JavaServer
Faces+ - JSF 1.1, 1.2 and 2.0 - enabling creation of bookmark-able,
pretty URLs. PrettyFaces solves the "RESTful URL" problem elegantly,
including features such as: page-load actions, seamless integration with
faces navigation, dynamic view-id assignment, managed parameter
parsing, and configuration-free compatibility with other web frameworks"

best approach would be http://www.phpbb.com/ :-)
seems crazy going to all that hassel, phpbb is so simple, infact a lot of jsf forums such as primefaces [http://primefaces.prime.com.tr/forum/] use phpbb, as you can have your fourm up and running in no time

  • Download link with parameters.

    I've created a generic download function that takes a couple of parameters. The function works but now I'm trying to find out how to provide a download link that has the parameters filled in based on some page items.
    Page items:
    P38_export_type: The user can select what kind of data to download
    P38_filename: The user can provide a filename
    What I've tried is to create a button: Redirect to URL
    #OWNER#.download_my_file?p_application_id=&APP_ID.&p_filenaam=&P38_FILENAME.&p_functie=Statistiek&p_parameter1=&P38_EXPORT_TYPE.
    Although this creates a link, the parameters are filled on page load. This is to early, I need the values at the time the button is pressed.
    Any ideas how to do this?

    Hi thanks,
    In the meantime I figured out something similar.
    function my_redirect ()
      redirect(html_GetElement('P38_OWNER').value+".download_my_file?p_application_id="+html_GetElement('pFlowId').value+"&p_filenaam="+html_GetElement('P38_BESTAND').value+"&p_functie=Statistiek&p_parameter1="+html_GetElement('P38_SOORT_EXPORT').value);
    } I struggled a bit with the owner value before I decided to put it in a hidden field. Passing it as a variable is a better idea.
    It seems that accessing the item values can be done in several ways.
    redirect or location.href=URL ? any preference?

    use the column link because I already use to

  • Runtime error after successful compile and link with cl.exe

    Finally, got the configuration for cl.exe and link.exe right and got a successful compile and link to produce a dll. Then ran the main method of my Java class.

    The dll I'm wrapping is C++ VC++ compiled.
    Would like to know what I do to trouble-shoot this error and hope to fix it?
    Jim

    Using Java print statement was able to show that the my JNI dll was being loaded and that the problem was in the first call to one of my JNI functions. Then by using "DebugBreak()" in that function and gradually moving it down line by line through the function was able to isolate the line causing the problem. Unfortunately it is the line where I call a function from the dll I'm wrapping. See newer thread.

    Soniya Kapoor

    Hi,
    Ad Code #1
    First of all the key for BKPF consists of:
    BUKRS, BELNR and GJAHR so I think you should use all key fields in your SELECT statement:
    select single * from BKPF into I_BKPF
    where BUKRS = l_s_DTFIAP_3-BUKRS and
          BELNR = l_s_DTFIAP_3-BELNR and
          GJAHR = l_s_DTFIAP_3-GJAHR.
    And why do you test SY-SUBRC after CLEAR ?
    Your IF statement should be after SELECT...
    And last but not least when you are using SELECT SINGLE you always get only one record so what is the purpose of LOOP statement ?
    Try following code:
    case I_datasource.
    WHEN '0FI_AP_4'.
      loop at C_t_data into l_s_DTFIAP_3.
        l_tabix = sy-tabix.
        select single * from BKPF into I_BKPF
          where BUKRS = l_s_DTFIAP_3-BUKRS and
                BELNR = l_s_DTFIAP_3-BELNR and
                GJAHR = l_s_DTFIAP_3-GJAHR.
        if sy-subrc = 0.
          if (I_BKPF-TCODE = ‘FV50’) OR
             (I_BKPF-TCODE = ‘FB01’).
            I_FINAL-BELNR = I_BKPF-BELNR
            modify I_FINAL.
          endif.
          modify C_t_data from l_s_DTFIAP_3 index l_tabix.
        endif.
      endloop.
    endcase.

  • Add a link with command to print some pages document automaticly of a PDF

    Hello, I have a PDF document of 200 hundred pages. I would like to create a link which one will print determined pages when I click on.
    How can I do this ?
    For exemple, I have a link zone and when I clik on this zone I want to print automaticly the pages 3 to 14.
    Thanks a lot,
    Éric Gervais

    Use Acrobat JavaScript for the link's action:
    this.print(false, this.pageNum, this.pageNum);
    // Print a file silently
    this.print({bUI: false, nStart: 2, nEnd: 13, bSilent: true, bShrinkToFit: true, bPrintAsImage: false, bReverse: false, bAnnotations: false});

  • JSf and work with Clipboard

    Hello,
    I have this problem:
    I have JSP page with datatable and on disk I have an Excel file.
    I want to copy and paste from Excel file to datatable and vice-versa.
    To access the Clipboard I use:
    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();and so on. It works in standalone application.
    But when I use copy or paste its used the Clipboard of server instead of client clipboard.
    Any idea how to solve this problem will be appreciated.
    Thanks

    Run it at the client side. If you want to use Java for this, use an applet or webstart application.
    By the way, that´s an odd requirement .. Copypaste from Excel on disk to a JSF datatable .. ?
    What´s the use of it? Where´s that disk which you´re talking about? At the client machine or server machine? If the client machine, do you realize that the server would only be able to access the client´s disk when they both runs at physically the same machine? The only way to let the server access the client´s file using a web application is to let the client upload the file to the server. Otherwise you can´t go around an applet or webstart application.

  • Problem to create a link with parameters using a PL/SQL function body

    Hi everybody,
    I need some help to create a link on a SELECT statement.
    I have a region report with type "PL/SQL function body return SQL query".
    I would like to use a link using HTML tag <a href>.
    I know how to do the link, but I don't know to pass a parameters in <a href> statement.
    Always I tried it doesn't work well.
    My PL/SQL anonimous block is, (just with link) :
    DECLARE
    q vARCHAR2(4000);
    BEGIN
    q:='select     "INDICADOR"."NRINDICADOR" as "NRINDICADOR",';

    Thanks for any help,
    Alessandra

    Your code is in a default value for an item, right?
    You need to make sure :P33_YEAR is not null and handle the error in the PL/SQL if it is.
    How is P33_YEAR populated? do you pass it in? check to see if it is making it there..

  • Trying to use form or dynamic link with parameters in a portlet

    I have created a dynamic page and published it as a portlet. The dynamic page is my own customization page for a chart.
    Ont he same page as the portlet I have the chart I want to customize. I have tried defining the form action as the page itself with the extra custom parameters in the url and I have tried just building up a url and callong that url (if we have a link on the chart names that is what happens and it works). However, it doesn't work.
    It should read (and does when I use a javascript alert): http://ogg:7777/servlet/page?_pageid=134,148&_dad=portal30&_schema=PORTAL30&_mode=3&city=Berlin
    but instead using a form it reads:
    http://ogg:7777/servlet/page?city=Berlin
    and using the link building method it reads:
    http://ogg:7777/servlet/
    What is happening to the link in either case? Why is it being altered? I've left the form action blank and also tried hard coding the URL but still get the same response.
    null

    We are doing something similar with our own customization form and the report it affects on the same page. We will also be doing the same thing with charts in the future. It took a great deal of trial and error, but we finally have a technique that works (even if it isn't ideal).
    1. The following is entered in your form in the "On successful submission of a form, execute this PL/SQL block or PL/SQL procedure" (this will retrieve your parameter value from your form and then call the page your form and report (or chart) are on):
    declare
    hv_myvariable varchar2(2000);
    l_store portal30.wwsto_api_session;
    begin
    -- Note that you have to add the 'A_' in front of your form field name!
    hv_myvariable:=p_session.get_value_as_varchar2(
    p_block_name => 'DEFAULT',
    p_attribute_name => 'A_MYVARIABLE'
    -- call the url of the page
    go ('http://host:node/servlet/page?_pageid=65&_dad=portal30&_schema=PORTAL30&_mode=3&myvariable='&#0124; &#0124;hv_myvariable);
    end;
    2. The following is entered in the report's "Additional pl/sql code- Before displaying page" to retrieve the parameters from the url:
    portal30.wwv_name_value.replace_value(
    l_arg_names, l_arg_values, p_reference_path&#0124; &#0124;'.myvariable',
    portal30.wwv_standard_util.string_to_table2(get_value('myvariable')));
    3. At this point, the process should work, but it will clear out your form fields when you refresh your page. To prevent this, enter the following for the default value of your form field:
    portal30.wwpro_api_parameters.get_value('myvariable','FORM_MY_FORM')
    Let me know if this works for you or if you have found other ways to accomplish some of these things. If anyone else can show us a better way to do this or any other useful techniques, we would greatly appreciate the help!

    Is it possible to print a multiple page pdf document as well as any imbedded links in that document - with one click?

    Hi Sunnihval,
    No there isn't any option to print the mails as well as attachment with one go.

  • Hyper Link With Parameters

    I have an display item on Page 1, which is a link.
    In the default box of its attributes I have
    @a href="f?p=&APP_ID.:197:&SESSION."@@font color = 'Red'@My [email protected]/[email protected]
    In the post I have replaced the < and > with a @
    This works perfectly well
    What I would like to do is when the link is clicked, go to Page 197 and set the Search field to equal a value from Page 1.
    ie, where :P197_SEARCH = :P1_TEXT
    Can I put this in the link ?

  • AddEventListener and Function with Parameters

    Hello guys
    I got this situation
    nameTxt.addEventListener(FocusEvent.FOCUS_IN,formTextHandler);
             private function formTextHandler(text:String):void{
    where i want to send some additional information too
    so how could i do that?
    Thanks

    hi,
       it seems like you will need to extend your text Component and Event class as well. Its not clear from your code that what component you are referring to . so generally you will extend your required component .
    you will need to addEvent Listener
    FocusEvent.FOCUS_IN
    in your custom extended component and in the handler of that focusEvent you will dispatch your new custom event with the parameters from this FocusEvent you received and as well as new parameters that are also required by your new extended Event.
    Method of extending events is straight forward. e.g this a sample for extending Events you will need to modify it with the paramaters you require in your event .
    package
        import flash.events.Event;
        public class AccountEvent extends Event
            public var accountObj:Object
            public static var NewAccount:String='newAccount'
            public function AccountEvent(type:String,newAccount:Object)
                super(type)
                this.accountObj=newAccount
    and here is the code how to use this event
    package
        import flash.events.Event;
        import flash.events.FocusEvent;
        import AccountEvent
        import mx.controls.TextInput
        public class customText extends TextInput
            public function customText()
                super();
                addEventListener(FocusEvent.FOCUS_IN,onFocus)
            private function onFocus(e:FocusEvent):void{
                dispatchEvent(new AccountEvent(paramaters.....///here you will add your custom paramerters and 
               //you will catch this event in your main application rather then catching the focus in event
