How pass url parameters on init webdynpro app.?

Hi all,
i want to pass a parameter to my wd app. when its start. How can i do it? where do i have to do it?
Thanx in advance
CP

You can define parameter using two methods:
1. Via properties of the iview you have created, system will pass these parameters automatically to the iview.
2. Via Code, you can use Portal Navigation and pass parameters at runtime. Check following sample code:
          WDPortalNavigation.navigateAbsolute(
                    "ROLES://portal_content/myIview/LoadEmployees",
                                WDPortalNavigationMode.SHOW_INPLACE,
                                (String) null,
                                (String) null,
                                WDPortalNavigationHistoryMode.NO_DUPLICATIONS,
                                (String) null,
                                (String) null,
                                "action=E");
The last parameter is for passing parameters, in the example parameter name: action and its value: E.

Passing URL parameters to WD application

Hi!
To pass URL parameters to WD application I currenly inbound plug 'defauld' (of type 'Startup') of main window. I use following code:
types:
    begin of param_t,
      name type string,
      value type string,
    end of param_t.
data: params type standard table of param_t.
data: param like line of params.
wdevent->get_data(
    exporting
      name = '_ALL_URL_PARAMETERS'
    importing
      value = params
It works fine but this plug is called after init methods of the component controller an of the view. So if I want to do something with parameters, I must do in this plug.
Is there way to pass URL parameters in a WD app. so that they were available from the very beginning of the application work i.e. in init method of the component controller etc.?
Thanks!

I had the same requirement too. There are a couple of threads on the subject as well, I've posted in one of them but had no answer:
Re: Read URL Parameters programmatically
The workaround i've used is this, it's definitely not as neat as I would like to since you end up having two initialization methods per controller, WDDOINIT and the one you create (for each controller you want to run code in using the received parameters). Nevertheless, it works:
1) Create an event in your component controller, for example INIT_COMPLETED.
2) Define a new method in your component controller, e.g. INIT_AFTER_WINDOW. This method receives an Importing parameter TYPE tihttpnvp. It uses this received HTTP parameters for the initialization logic and finally raises the INIT_COMPLETED event (This is the method that "replaces" WDDOINIT).
3) In the Window's Inbound plug handler, you get the HTTP parameters (with wdevent->get_data) and afterwards call the method WD_COMP_CONTROLLER->INIT_AFTER_WINDOW (maybe you need to declare the usage previously in the Window to have the reference available).
4) Finally, if you need some of the Views to be initialized afterwards the component controller's INIT_AFTER_WINDOW runs (for example to show some initialization messages), you'll have to replace the WDDOINIT method with an INIT_AFTER_COMPCTRL method and subscribe it to the component controller's INIT_COMPLETED event.
I hope you got the idea, and more importantly, that we get some cleaner solution from SAP for achieving this in the future.

INIT_AFTER_WINDOW is the method to be called on step 3

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.

Trouble Passing URL Parameters between Applications

Hi All,
I am having trouble Passing URL Parameters between Applications for BW queries as data sources. I know I am getting the data from the sending application correctly, because I an printing to the screen using a Text Component.
Date From: 1/1/2008
Date To: 3/14/2014
Here is the code from the sending application On Select :
"http://localhost:56572/aad/web.do?APPLICATION=WIMO_SUMMARY_OPEN_DETAIL&designersessionid=37a1cfaa7e734cd9afa35cb4cd627d41" +
+ DS_1.getVariableValueExt("ZPORDAT3") +
+ DS_1.getVariableValueExt("ZPORDAT5"));
Here is the code from the recieving application Global Script Variable"
Xv_DateFrom     String     True
Xv_DateTo         String     True
Here is the code from the receiving application On Startup"
DS_2.setFilter("0CALDAY",[Xv_DateFrom, Xv_DateTo]);
When I click the results of the sending Application the popup window opens for the receiving application but I get all the records for the BW receiving query, it does not restrict to the values in ("ZPORDAT3") 1/1/2008 and ("ZPORDAT5") Date To: 3/14/2014.
So, I would expect it is my receiving code, but I am not sure.
Hope you can help?
Norman

Hi Norman,
As Jörg said, please put "&" before each of your variable names at your url. For the second part,I didn't try it for date intervals but keep in mind just in case:
APPLICATION.openNewWindow("http://localhost:56572/aad/web.do?APPLICATION=WIMO_SUMMARY_OPEN_DETAIL&designersessionid=37a1cfaa7e734cd9afa35cb4cd627d41" +
"&Xv_DateFrom=" + DS_1.getVariableValueExt("ZPORDAT3") +
"&Xv_DateTo=" + DS_1.getVariableValueExt("ZPORDAT5"));
Here is the code from the recieving application Global Script Variable"
Xv_DateFrom     String     True
Xv_DateTo         String     True
Here is the code from the receiving application On Startup"
DS_2.setFilterExt("0CALDAY", {"low": Xv_DateFrom , "high " : Xv_DateTo});

Passing URL parameters to WD app in URL IView

Hi experts,
I'm using EP 7.2 and as I found out this version doesn't support Web Dynpro Java iview template so I'm using URL iview template for my Web Dynpro Java application. My requirement is to somehow pass some URL parameter (which is id for something in my app) to the WD app in the URL iview. So in this scenario setting the URL parameters and their values during design time for the iview is not suitable. I tried DynamicParameter=id%3D154 for example but it doesn't work. Do someone has any ideas to solve this problem? Any help will be appreciated.
Regards,
Martin
Edited by: musaka on Oct 27, 2009 1:12 PM

Hi Musaka,
If i am not mistaken, your requirement is to display a URL iView to user with some parameters (contained within the Address Bar of the Browser) to be passed to the iView. Initially as no parameter value can be defined on previewing the iView or opening the iView, no value is passed to iView. But in case, when you directly enter the Parameter Values against Parameter Names in Address Bar and then say go, the page should reload and pick the parameter values from URL in Address Bar instead.
Steps to follow:
1. Put CustomerId=0&RequestId=0 in the Application Parameter property of the URL iView.
2. Put the following lines of code in the wdDoInit() in the implementation tab of the View Controller to retrieve and use the passed parameter value in the View of the application and then say Organize Imports from the context menu.
int customerId = WDProtocolAdapter().getProtocolAdapter().getRequestObject().getParameter("CustomerId");
int requestId = WDProtocolAdapter().getProtocolAdapter().getRequestObject().getParameter("RequestId");
Please revert in case of any issue.

Passing an XML file from WebDynpro app to ABAP function module

Hi all,
I'm stuck with a problem, and am hoping one of you could let me know how to proceed:
I need to pass an XML file (or at least the entire content of the XML) from my WebDynpro application to a backend ABAP function module. What I tried was this:
In my WebDynpro app, I read the XML and convert the content into one long string (using java.io.FileReader and java.io.BufferedReader). In my ABAP function module I created an import parameter of type String. I then imported the ABAP Function module into my WebDynpro app as a model. I then tried to pass the XML string to the ABAP module. What happens is this:
If the size of the string (XML) happens to be less than 255 characters, then it works. That is, the string is passed to the ABAP function module and I can see the contents. However, if the XML string happens to be greater than 255 characters, then it does not work. The string at the ABAP side is empty. Surprisingly, the ABAP module does not throw an error either. It just displays an empty string.
Could you please tell me what the problem is?
Thanks & Regards,
Biju

Hi Biju ,
Welcome to SDN.
If the import parameter is defined as type string it should work, however did you check whether your application pass it properly?
I have applications using strings as import parameters working fine. (webapplications (BSP) to RFC)

Reading URL parameters in ABAP webdynpro

I have a requirements to run my ABAP Webdynpro application view based on two parameters passed to it from portal. How can I read the parameters in ABAP webdynpro and use them to write my condition in the run time. I would appreciate it if someone has any code that would help me also.
Again your help and support is highly appreciated.
Lily

Hi Lily,
To read the URL parameters, you need to right the following code in the HANDLEDEFAULT method
of the your default window controller.
DATA : it_parameter TYPE tihttpnvp,
         wa_parameter TYPE ihttpnvp.
DATA lo_nd_url_param TYPE REF TO if_wd_context_node.
DATA ls_url_param TYPE wd_this->element_url_param.
" Get all URL parameters
CALL METHOD wdevent->get_data
    EXPORTING
      name = if_wd_application=>all_url_parameters
    IMPORTING
      value = it_parameter.
" Get parameter values
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'PERNR' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-pernr = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'SUBTY' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-subty = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'BEGDA' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-begda = wa_parameter-value.
ENDIF.
CLEAR wa_parameter.
READ TABLE it_parameter WITH KEY name = 'ZZPRNTOPT' INTO wa_parameter.
IF sy-subrc EQ 0.
    ls_url_param-zzprntopt = wa_parameter-value.
ENDIF.
" Save URL parameter to context
lo_nd_url_param = wd_context->get_child_node( name = wd_this->wdctx_url_param ).
lo_nd_url_param->set_static_attributes(
     static_attributes = ls_url_param ).

Many Thanks
Ganesh

Hi Mick,
Thanks for your reply. However my problem is still not resolved.
I have created a Omniportlet with lists the staff details. When I click on the staff link I am passing to parameters as follows
http://servername/pls/portal/url/PAGE/CCM_MIS_PORTAL/TUTOR_HOME/Course_Info?Param1=10017031/M2523&Param2=001434
on the receving page I have a omni portlet which must receive these 2 parameters and pass it on to the query and filter the results.
On the received page I have created 2 page parameters (Param1 and Param2)
I have assigned these 2 paramaters to the portlet paramers through page parameters' section
on the omni portlet in the query I have created 2 bind variables (p1, p2) and the default value of the bind variable is set using ##Param1## and ##Param2## so the received values from page is passed to to bind variable and hence to the query.
However the omni portlet is not received the parameters and I can not figure out whats wrong?
Is there any problem with my URL (guide says I should use relative URL)
Please help

HTTP reciever adapter pass URL parameters

Hello all,
I have a question regarding passing parameters as querystring in the url of reiever HTTP adapter. This is an RFC> XI> HTTP scenario and we're posting to an external URL. Here are the details
URL: xxxx.yyyyy.com

It works fine with these. I want to pass a parameter called "bulk" with value "1".
How should I do it. Should I append it to the Path directly like

or enable Apply URL Parameters under Adapter Specific MJessage Attributes and fill in
Parameter 1 : bulk=1
Could somebody clarify this please?
Thanks

Webcenter Portal PPR Navigation and Passing URL parameters

Hi,
We have pages that will be URL parameter based so that it can be bookmarked and should be partially page navigable. Basically some pages are specific to project numbers i.e a project-page is opened by passing something like project-page?projectNumer=111. We have a partial page navigation something like this..
<af:commandLink id="pt_cl22"
actionListener="#{navigationContext.processAction}"
action="pprnav" text="#{menu.title}"
styleClass="primaryNav">
<f:attribute name="node" value="#{menu}"/>
</af:commandLink>
The problem is this pprnav doesn't allow us to pass http parameters. Is there a way to pass parameters through the URL without actually refreshing the whole page (using goLinks). It is important for us since most of the pages have obiee dashboards which take time to load. Or how to parameterize the pages with pprnav enabled. We tried unbounded taskflows but doesnt go well with webcenter portal.
Thanks,

may be u should try to set the action programatically. using the approach specified in this blog..
http://andrejusb.blogspot.com/2011/10/how-to-disable-action-conditionally.html
(just follow the approach defined for setting pprnav programatically). before setting the ppnav set some variable in the parameter list of in the pageflowscope.. and use the pageflowscope in the next page

Pass URL parameters to parent window, which is not in VC

Hi,
I developed a web application which is calling a VC iView in a new browser window, now I have the problem that I have to pass back URL parameters to the parent window. Is there any possibility to use JavaScript or is there some other solution?
Thanks fpr your help.
Kind regards,
Timo

Hi Mario,
thanks a lot for your answer. If I understand correctly your solution works only if the other web application in the parent window is also located in the portal, unfortunately my web application is outside the portal.
Is there a solution for this, or should I look for something else than using Visual Composer?
Kind regards,
Timo

Passing Data Back from a WebDynpro App to a Portal App

Hello all,
We have an iView in the portal that has a link to a webdynpro application. When the link is clicked, it opens the webdynpro app in a new window. When a user selects data on this window and clicks a button, I want that data selected transferred to a specific field on calling window.
Prior to using webDynpro, we were able to do this by using the code below on the called page.
<SCRIPT language='JavaScript'>
function SelectUser() {
var selectedUserAdmcd=document.all["EMP_ADMCD_RET"].value;
window.opener.document.forms[0].ADMIN_HR_CODE_NEW.value=selectedUserAdmcd;
Any suggestions will be appreciated.
Thanks,
Mike

Hi Mike,
The SAP Enterprise Portal 6.0 supports client-side eventing. I dont thhink you cannot write Java Script code in a Web Dynpro application, a Java wrapper enables you to implement portal eventing. You can subscribe to and unsubscribe from specific portal events. This means that the SAP Enterprise Portal can react to an event that is triggered by a Web Dynpro application.
Sample code for the same
In the sender application, On action of the button click event.
String parm=wdContext.currentContextElement().getInput();
WDPortalEventing.fire ("urn:com.sap.tc.webdynpro.example.portaleventing", "Event Name ", parm);
In the listener application
In the Init method subscribe the portal event
WDPortalEventing.subscribe("urn:com.sap.tc.webdynpro.example.portaleventing","Event Name ", wdThis.wdGetReactPortalEventingAction() );
Create an action ReactPortalEventing. Add the parameter data of type java.lang.String.
wdContext.currentContextElement().setOuput(dataObject);
The value of the element Input recieved in the Sender application will mapped to the element Output of the listener application.

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.

Web Dynpro iView - how to pass URL parameters?

I have a Web Dynpro application that is housed in the Enterprise Portal. We have a requirement where we need to provide an external link to the iView/Web Dynpro component - for the sake of this discussion, assume it's email. As part of this URL link, we need to pass a parameter that will cause the Web Dynpro app to fetch some data.
The Web Dynpro has a startup plug parameter - call it 'id'.
I can invoke the Web Dynpro application directly, and pass the id paramter on the URL - the application can see the parameter just fine. However, when I try and do the same via a Roles-based URL, the parameter does not survive. I've tried two different methods:
http://host:port/irj/portal?NavigationTarget=ROLES://path/to/iview&id=1234
and
http://host:port/irj/portal?NavigationTarget=ROLES://path/to/iview!26id=1234
neither of which work.
is there a way to do what I'm trying to do? Note that the 'id' paramter is dynamic - I can't code it in the Web Dynpro iView configuration.

Hi,
please try the following:
http://host:port/irj/portal?NavigationTarget=ROLES://path/to/iview&DynamicParameter=<encode(id=1234)>
The value of the DynamicParameter value must bei encoded.
For details please have a lool to

This book will be also available in English soon.
