Portal Events in web dynpro

Hi All,
I have created two web dynpro application iviews on the same page.
Now there is a button on the first application and when that button is pressed then I am triggering an event TRIGGER from it using method FIRE.
There is a text edit element on the second application.
I have registered the event TRIGGER in the second application in method WDDOINIT using method SUBSCRIBE_EVENT and assigned an action RECEIVE to it.In the method ONACTIONRECEIVE I have set data to be displayed in the text edit element.
However the above scenario is not working.
In methods subscribe_event and fire there is a parameter to be passed which is PORTAL_EVENT_NAMESPACE.What exactly is this parameter and what value to be passed to it.
Please provide any source code if any.
Thanks in advance

Hi Aman,
If you are still not able to do the Portal eventing then to make portal eventing work you should access portal using FQDN (fully qualified domain name).
Check Sap help for [Fully Qualified Domain Names |http://help.sap.com/saphelp_nw70/helpdata/en/67/be9442572e1231e10000000a1550b0/content.htm] also check the SAP note 654982.

Portal Eventing between Web DynPro Java iView and non-Web DynPro iView

Dear Experts,
I have 1 Web DynPro Java iView and 1 non-Web DynPro (using JSPDynPage and JSP) iView, both attached to a page. When Web DynPro Java iView fire a portal raise event, the portal iView did not execute the javascript function tied to the event subscribed.
Here is the code snippet which reside in the Web DynPro Java iView that is used to fire the event
String param = "test";
WPortalEventing.fire("urn:com.company.Test1", "TestEvent", param);
This the code snippet that is in the jsp page
function notifyTest(param)
     // Code to print param value here
EPCM.subscribeEvent("urn:com.company.Test1", "TestEvent", notifyTest);
Note:
1. When Web DynPro Java iView fire the portal event the entire page is refreshed, including the non-WDP iView.
2. When EPCM is replaced with window.top.EPCM, the page is refreshed, it is totally hanged with progress bar.
Can anyone help to solve this problem?

hi
Please write the below code snippet in ur jsp for notifyTestjavascriptfunction
function notifyTest( eventObj ) {
     eventParameter=eventObj.dataObject;
     // code to print the parameter "eventParameter"
Thanks

Eventing between Web Dynpro iView and regular DynPage iView

I have seen, done eventing between two dynpage iviews and two webdynpro iviewsHowever, and gone through "How to Use the Portal Eventing for Web Dynpro iViews". However, I have been trying to have a webdynpro iview talk to a dynpage iview but they just won't communicate. Is this even possible?
Ok basically I have a portal page in a popup window with no masthead and top level navigation. The page has two iviews - the top one being an iView that points to a webdynpro application on Server A, and the bottom one being a dynpage iview on the Portal Server B.
In the webdynpro iview, the code for when a button is clicked is
public onSomeAction(Event event) {
    WDPortalEventing.fire("urn:myUrn","eventName","value");
In the dynpage iview, the code i have for it is
myServ = (IEpcfToolbox) PortalRuntime.getRuntimeResources().getService(IEpcfToolbox.KEY);
myReceiver = myServ.getClientEventReceiver(request, "urn:myUrn", "eventName");
form.addRawText(myReceiver.getWrappedScript());
try {
    if (!myReceiver.isReceived()) {
        form.addComponent(createMainScreen());
    } else {
     form.addComponent(new TextView("event received!"));
} catch (Exception e) {
    form.addComponent(createErrorScreen());
I tried all the things I could think of but the receiving iView just won't get the event fired.
Can someone confirm that this should work? and correct me where I've done wrong.
Please help. this is very urgent. your help will be greatly appreciated. thanks in advance

I am no direct access to the boxes so I can't try your suggestion. It really makes sense that eventing won't work if the iViews are on different domains. I know they are in the same domain but different subdomains.
Anyway, good news I got eventing to work with the mentioned set. I found that that the SAP Java EPCFToolbox API had a bug that kept throwing javascript errors when I tried to have the web dynpro iview fire an event and the SAP one subcribed to it.
I got around it but using the EPCF Javascript API instead.
Code:
response.write("<script>");
response.write("EPCM.subscribeEvent('urn:dla.telework', 'createPdf', doSomething);");
response.write("function doSomething() {");
response.write("window.location = self.location + '&eventReceived=true';");
response.write("}");
response.write("</script>");
So basically just output raw text through the response object and it just works.
On a similar topic, since eventing can only pass string parameters back and forth, I'm still looking for a way to pass other more complex Java objects between web dynpro and sap iviews. From what I haven't they don't share the same session object (which I thought they did). So basically I can't just stick stuff in the session and pull it down on the other end. I'm clueless right now. If anybody has some tips, plesae share. Thanks

Userid of a Portal-user in Web Dynpro ABAP

Dear colleagues,
we want to migrate our application from BSP to Web Dynpro ABAP and I'm looking for a procedure how I can get the userid of a Portal-user in Web Dynpro ABAP which is running inside an iView ?
In BSP I used iView application parameter user_id and in the BSP the event handler for data retrieval with:
userid = runtime->server->request->get_form_field( 'userid' ).
Found a lot of entries how to do it in Java but no one for WDA ?
Thanks in advance
Michael

Hi Michael,
Actualy it is not so trivial. You have some options:
1) In case user_id is parameter of iView you can read URL parameter like described here Webdynpro ABAP url-parameters
2) In case user_id is not iView parameter you can use usuall ABAP <i>sy-uname</i> system variable.
But pay attantion that it is not really EP user. Here we have 2 options: user mapping and SSO. In case of user mapping <i>sy-uname</i> will contain R/3 user which is mapped to EP user. In case of SSO <i>sy-uname</i> will contain same user name like in EP, because by using SSO user must ne the same on issuing and accepting systems.
Best regards, Maksim Rashchynski.

Push data/ trigger event in Web Dynpro app

Hello All.
I'm a newbie with web dynpro. I have a need to push information to a web dynpro application. Is there a way I can trigger an event in web dynpro to refresh the screen from another application running on the Netweaver J2EE? Is it possible to implement an ActiveX or AJAX application to retrieve server data and communicate with a web dynpro app running on the enterprise portal?
Your help will be appreciated.

Handling standard iview event from web dynpro

Hi all,
I hav w a search iView which is SAP standard, when you click an element on the result list it triggers an event. The link contains the following:
javascript:{jsCode="
EPCM.storeClientData('urn:com.sap.bor:BUS1001','objid','12002');
EPCM.storeClientData('urn:com.sap.bor:BUS1001','AllKeys','objid');
EPCM.raiseEvent('urn:com.sap.bor:BUS1001','select','','a very long url');"};if(opener!=null&&self!=opener){opener.execJS(jsCode);}else{execJS(jsCode);};
On the other side I'm developing a custom WebDynpro iView whick needs to handle this event. By adding to wdInit() the line WDPortalEventing.subscribe("urn:com.sap.bor:BUS1001", "select", wdThis.wdGetGetReportsListForMaterialAction()); I was able to catch the event. But I can't get the parameters from the event.
For what i've learned browsing the forum the javascript code above stores the parameters in the "client data bag", and are not directly passed in the event.
Is there any way to retrieve these parameters from the Web Dynpro iView ?
Thanks in advance,
Diego.

Hi all,
As a workaround I made a Portal Component application which receives the event and parameters from the standard iView and lanuchs a new event setting the aprameters in the event as Web Dynpro expects them (without using the client databag). Then I inserted this Iview in the same page as the others, but hidden. It's not elegant but is working.

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks

Can the role info be passed from portal to ABAP web dynpro application

Hi,
We have some roles in the portal. We call the ABAP web dynpro applications from the portal. Is it possible to pass on the role from the portal to the Web dynpro ABAP application so that we can use this role information in the application.
Thanks,
Pooja

Hi,
you can try to add the expression
role=<IView.PCDUnit>
as part of the Application Parameters in the iView. This will be the role in 99%. However not all iViews started in the Portal must belong to a role. You can start iViews using page navigation that are not part of a role. Therefore the PCD does not talk about roles but about "units" which is the superordinate term.
the value will be the PCD path of the role - e.g:
portal_content/myFolder/roles/myRole

On Blur, On Click Events in Web Dynpro - How can it be done ?

Hello All,
I am wondering if it would be possible to have
On_CLick
and
On_Blur
events using Web Dynpros, it would be great if any one can tell me how it is done or provide me some documentation, I have done it using HTMLB but dont know how to do it using Web Dynpros.
I would appreciate any help.
Best Wishes,
John.

Hi John,
As Maksim said you can use the onClick event with some of the UIElement.
for example:
Add a button UIElement to your view
create a new action in the view.
Write in the action something like:
wdComponentAPI.getMessageManager().reportSuccess("Hello John");
In the properties of the button you will see an onAction event. Bind it to the action that you created.

Using KM and Collaboration API in portal component and web dynpro

Hi,
I have to develop portal components and Web Dynpros (JAVA) which have to use the following functions:
- copy, delete KM documents
- sending E-Mails
Can anyone give me some actual documentation links for the KM and Collaboration APIs ?
Which references do I need in portalapp.xml for KM/collaboration and which jar-Files do I have to add to the project?
We are using NetWeaver 7.01 SP18.

Hi Yogalakshmi,
thank you for the link and the information. Now I managed to work with the KM documents.
One more Question: to get the resource Context, I use this code:
portalUser = WPUMFactory.getServiceUserFactory().getServiceUser("cmadmin_service");
IResourceContext resourceContext = new ResourceContext(portalUser);
The method getServiceUser is deprecated, also the com.sapportals.portal.security.usermanagement.IUser is deprecated. Is there an other possibility to get the ResourceContext. (perhaps with com.sap.security.api.IUser) ?

Catch event from Web Dynpro for Java

Dear guru's,
we have a working Web Dynpro for Java. It delivers a company code that needs to be routed to a visual composer model. In the Web Dynpro we use the WDPortalEventing.fire command to trigger an event named 'ShowCompanyCode' in namespace com.sap.vc:epcm. In the visual composer, I used a 'signal in' for the same namespace and event name. However, the supplied value for the company code is not received. Both iviews (from VC and Web Dynpro) are on one page.
I have enabled the flash debug console and did some testing with a VC model that consists of two iviews on one page. Here it does work. I have found some differences in the debug output that points in a direction.
In the case of the VC iviews, I get the following string in the debug console: signalinAHAPP -<Params version="2" ><Row STR1="1000" /></Params>. This results in a correct transfer of company code value '1000'.
When getting the info from the Web Dynpro iview, I get the following string: signalinAHAO8 -1000. It seems that the web dynpro does not supply the values in a correct way. However, the same mechanism is used to supply the data to another web dynpro iview and that works fine.
Do we have to use special coding to be able to fire the event to a VC iview? Any help will be appreciated and points will be awarded!
Thanks,
Arno

A. Van de Camp,
You can create two iViews that communicate with each other on the same page, using client-side eventing, so that the output of the first iView serves as the input to the second. Eventing in the portal is based on the use of the Enterprise Portal Client Manager (EPCM), an object defined by the portal client framework to handle functions such as client eventing.
To define eventing between an iView created and existing in the portal(web dynpro iview), and an iView created in Visual Composer:
1.Check the properties of the existing portal iView and find out its EPCM event name.
2. In Storyboard, open the iView that is to be the second part of the eventing scenario and create the required port: as input or as output.
3. Double-click the newly-created port and in the Configure Element task panel, enter the portal event name in the Signal name field and the EPCM event in the EPCM event field.

Sami

Portal DC consuming Web Dynpro DC? possible?

Hello
I am trying to consume a web dynpro DC in a portal DC (PAR) and have been unsuccessful so far.
Can anyone help me with this? Any useful links or articles?
The scenario is that I am using Web Dynpro - Adaptive RFC model to connect to the backend and get some data. I want a portal DC (PAR) to consume this web dynpro DC and use the data from the backend.
Regards,
Aditya

Hi Aditya
>I want a portal DC (PAR) to consume this web dynpro DC and use the data from the backend.
It depends on what you have in PAR...
If this is a Portal service you can invoke the service from the WebDynpro application and pass any backend data as you want.
If this is a Portal application then you should use Portal client events (EPCF).

How to catch URL parameter from Portal URL in Web Dynpro iView

Hi All,
I have a web dynpro application running as a portal iView successfully. Now the client wants to make it internationalized with 7 languages. Currently they access the portal - and via role assignment they get to the portal tab with the wd iView. Now they want to send a parameter for the language key with the portal URL. So when they are typing in http://myportal.mydomain.com now they want to type in http://myportal.mydomain.com?sap-locale=de or so. My question is how can I catch this parameter in the WD application when it is running inside a portal iView? Is it at all possible?
I have written a very small application which is trying to catch a URL parameter named PARAM. The code I have written is the default one as below:
String paramValue = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("PARAM");
When I run the application standalone and add the PARAM=something in last of the URL I can catch it. But when I create an iView and while previewing it I add the same PARAM value it is coming as null all the time. Same when I add this iView to a role and show it via role assignment in protal. Please help to let me know how to achieve this. I think if I can read the parameter value from Portal URL in the WD iView - then I can set it as the default locale of the application and then show language specific file to achieve internationalization.
Your urgent help will be highly appreciated.
Warm Regards,
Shubho

Hi Shubhadip
Even if you get the parameters, how do you internationalize your application? Are you not following the standard way as described in the following link. In this case you never need to capture any such parameter. This is done by the WD runtime automatically .
<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/f4/d95664da179b4db731e21c2e470b72/frameset.htm">Internationalization of WD projects</a>
You can retrieve application parameters specified at the creation of iview by "adding parameters(with the same name as in iview application parameters) to the default plug of the Component Interface View of the WD application". "onDefaultPlug" method of the interface view controller you get these values as parameters, which you can save in the context node of component controller for later use.This is guaranteed to work.
But again this is not what you want exactly. You want the user to specify the value at runtime. If you have just 7 languages, you can create 7 set of iviews with different application parameter value indicating language key, and assign to 7 different set of roles, each representing one set of users with common language.
I hope you find a solution.

kk
