How to read url parameters from a decoded string

Hi,
Normally if I pass on a url string
test.cfm?name=abc&num=8, I can do url.name and url.num
to get the url parameters. But what if the url string is decoded by
javascript escape() function? The above url string becomes
test.cfm%3Fname%3Dabc%26num%3D8
How can I read url.name and url.num from this string?
Thanks!
Min

Escape is not really meant for urls because it encodes the
delimiters: ? &

Hi Santosh,
You can read parameters send from one WebDynpro Component to another component by adding code in "HANDLEDEFAULT" Event Handler method ( Window )of your target Web Dynpro Component.
data: lt_parameter             type tihttpnvp,
         ls_parameter             type ihttpnvp.
lo_api_controller ?= wd_this->wd_get_api( ).
   call method lo_api_controller->get_message_manager
     receiving
       message_manager = lo_message_manager.
   clear : ls_parameter.
   refresh : lt_parameter[].
* Read all URL parameters
   wdevent->get_data( exporting name = if_wd_application=>all_url_parameters importing value = lt_parameter ).
if not lt_parameter[] is initial.
     clear : ls_parameter.
     read table lt_parameter into ls_parameter index 1.
     if ls_parameter-name = 'ACTION' and
        ls_parameter-value is initial.
       lv_flag = 'X'.
       clear : lo_msg.
       lo_msg = 'Action Parameter Missing in URL Link !'.
*         report message
       call method lo_message_manager->report_error_message
         exporting
           message_text = lo_msg.
     else.
     endif.

Hi,
let me see if I understand you well.
BSP -
You wrote the code for catching the user name in the event OnCreate, which means that you know who´s working with the BSP application when it starts.
Somewhere you must have a button or something with text like "Call WDA application". When user presses the button, it triggers events OnInputProcessing. Here you must write the code for the cookie that "sends" the parameter(s), something like:
CALL METHOD cl_bsp_server_side_cookie=>set_server_cookie
EXPORTING
    name                  = 'MY_COOKIE'
    application_name      = 'ZUSER_NAME_GET'
    application_namespace = 'ZUSER_NAME_GET'
    username              = sy-uname
    session_id            = 'SAME_FOR_ALL'
    data_value            = PAGE_DATA
    data_name             = 'PAGE_DATA'
    EXPIRY_TIME_REL       = 3600.
you call then the URL for the WDA application.
WDA -
probably in method WDDOINIT of the component controller you´ll write the code for reading the "content" of the cookie:
CALL METHOD cl_bsp_server_side_cookie=>get_server_cookie
EXPORTING
    name                  = 'MY_COOKIE'
    application_name      = 'ZUSER_NAME_GET'
    application_namespace = 'ZUSER_NAME_GET'
    username              = sy-uname
    session_id            = 'SAME_FOR_ALL'
    data_name             = 'PAGE_DATA'
CHANGING
    data_value            = PAGE_DATA.
read more about the cookies in SDN, because I am not sure if this is the correct example for transmiting values. I´ve used it in conjunction of instructions IMPORT and EXPORT for transmiting an internal table.
if this is not working properly, then try with IMPORT TO MEMORY and EXPORT FROM MEMORY.

How to read configuration data from an xml file (not web.xml)?

Hi,
I want to separate the application specific configuration parameters in a separate xml file and read them as and when they are needed? I know that I can use the wb.xml but I want to separate them in a different xml file because I don't want the web.xml file to be played around later after deployment. If any change is needed then it should be done in the application-config.xml.
How can I read the parameters from this xml file in my jsp code and also what should be the location of this file if I have
../webapps/Root/application
directoty structure ?
Any help is greatly appreciated.

can you give an example of a property file and also
it is loaded in the jsp ?Hmm... loading properties in a JSP is not a very good idea. You should do it in a separate class, rather than mixing the logic with the display logic.
Properties properties = new Properties();
properties.load(UtilClass.class.getResourceAsStream("config.properties"));
// Add a try - catch block around the load
// for IOException...

Live view doesn't correctly pass URL parameters from HTML docs?

Running into something that I wonder if anyone else has seen. I've created a site in DW CS5 with a local testing server (XAMPP on Win7), and if I use LiveView to view an HTML page that has a link to a PHP page that includes a URL parameter, the parameter shows up in the LiveView address bar, but the page doesn't seem to use it (trying to display an image where the file is built using $_GET to retrieve the parameter). The same HTML page, displayed in a browser, works. And if I then save the HTML page as a PHP page in DW, identical code, LiveView works. Sure looks like LiveView will does not properly handle URL parameters from HTML documents...

Sorry if I wasn't clear... the navigation works correctly; I get to the page I'm tyring to get to. One of the things that page should do is display an image, the I use a URL parameter to build the image file name to retrieve. The link in the first page is something like <a href="gallery.php?pg=1">. Works fine if the first page (the one I'm navigating from) is a PHP page, doesn't work (with the same code which is only HTML) if the page is an HTML page.
