Examples of 'calling a web dynpro application with parameters'

Hi!!
I'm I have been watching manual 'Web dynpro for abap: advanced concepts' in the sections 'url parameters' and 'calling a web dynpro application with parameters'.
Is there some example where these terms are seen.
Thanks in advance.

Hi Ana,
a window inbound plug can have parameters.
These parameters are automatically fished out of the URL by the framework.
So your inbound plug handler method has easy access to the parameters.
URL
http://<host>:port/sap/bc/webdynpro/sap/<your application>?param1=xyz&param2=abc
The application is configured to call an inbound interface(window) and plug.
The plug can be declared with parameters.
Double click on window inbound plug and add your parameters.
The parameters are made available by framework if present in Launch URL.
You can also call an application that has parameters directly entered on the parameters tab.
ie Parameters can be part of the application launch.

Phil

Calling a Web Dynpro Application from POWL feeder class

Hi,
I know this question is asked before but never answered, but I try again......
I have a own POWL feeder class where I defined a button in method IF_POWL_FEEDER~GET_ACTIONS.
I know that this action can be handled in method IF_POWL_FEEDER~HANDLE_ACTION.
When pressing the button I want do call another web dynpro application.
How can I do this? -> Any Example Coding?
Thank you and best regards, Edgar

Hi Vineet,
it works, thanks a lot!!!! Best Regards, Eddy
P.S.: Here is the coding for triggering the event and passing parameters for the selected POWL table line:
METHOD if_powl_feeder~handle_action.
DATA: ls_parameter TYPE powl_namevalue_sty.
DATA: lt_flights TYPE ty_flights.
DATA: ls_flight TYPE sflight.
DATA: ls_selected TYPE rstabix.
FIELD-SYMBOLS: <lt_fligts> TYPE STANDARD TABLE.
IF i_actionid = 'EDIT'.
* Important: this triggers the event
 e_portal_actions-fire_wdevent = abap_true.
* Pass parameters to event
 ASSIGN c_result_tab TO <lt_fligts>.
 lt_flights = <lt_fligts>.
* Determine the first selected row
 READ TABLE c_selected INTO ls_selected INDEX 1.
* Read selected POWL data
 READ TABLE lt_flights INDEX ls_selected-TABIX INTO ls_flight.
 CHECK sy-subrc = 0.
* Pass parameters
 ls_parameter-key = 'ACTIONID'.
 ls_parameter-value = 'I_ACTIONID'.
 APPEND ls_parameter TO e_portal_actions-parameters.
 ls_parameter-key = 'CARRID'.
 ls_parameter-value = ls_flight-carrid.

Passing a parameter while calling a web dynpro application on portal

hi
I am having a web dynpro application which retrieves data from R/3 system via RFC using Jco destinations define in the Portal.
Now we have different kinds of portals running on the same WAS, now I want the application to run which access data from different R/3 systems thru different JCo destinations.
I need to create a logic such that mu application runs fine on any portal with any Jco destination.
Is there any provision to achieve this.
kindly let me know about this.
Thanks and regards
kris

Gopi,
there's an parameter called "sap-wd-arfc-useSys" you can pass to the application, to change the used JCo-Connection (read more at http://help.sap.com/saphelp_erp2005/helpdata/en/f4/651741f163f023e10000000a155106/frameset.htm)
so, if you're running the WD-aaplication on one WAS and call it from different portals, you have to create three (or six with the META-connections) JCo-Connection on your WD-WAS.
In a WD-application you can access URL-Parameters with:
WDWebContextAdapter.getWebContextAdapter().getRequestParameter("<your URL Parameter-Name>");

Calling a Web Dynpro application from a web application

Hi everyone, I've got a problem I hope someone can help me resolve.
What I wanna do is to show a login form, which is part of a J2EE web application (contained in a SAP Web AS), an after the user submits the required information, I have to redirect the user to a Web Dynpro application, which is contained in the same Web AS, but I have to redirect this user using single sign on.
I'm not sure about what I have to do, I'm new in these technologies, I think I need to use UMFactory, but I have made some investigation and I'm not so sure about what I have to do yet, can anyone give me a hand with this?

but it is not working
thanks

Hi Mahesh,
You need to setup a Single Sign On between SAP Portal and ECC system where yoy are doing the development.
Ask basis team to setup the single sign on and usually this is the job done by Basis teams. Refer the below link to get some idea on SSO setup:

Seems like your example requires some other DCs as well, which don't appear to be part of the zip you mentioned.

Securing Web-Dynpro application with Netegrity

Hi,
I'm developing a web-dynpro application that will be secured by Netegrity SiteMinder. SiteMinder is a reverse-proxy that authenticates the user and adds the user details as additional headers to the HTTP stream. According to the documentation I found in SDN with regards to JAAS and NetWeaver it looks like SAP has added callbacks so that I can retrieve HTTP headers in my custom login-module. I've implemented a simple login-module and deployed it, but now am stuck with the following issues:
(1) I can't seem to be able to debug the module (even when I create a simple HelloWorld.jsp and require the use of this module in the visual administrator, the debugger seems to ignore the break-points).
(2) I can't find any possibility to configure the engine so that this specific module is required for authenticating my deployed web-dynpro application.
My questions are as follows:
(1) Is it possible to use standard JAAS authentication with web-dynpro applications?
(2) How do I debug JAAS login modules?
Regards, Chris.

Hi Adrian
During the Life cycle of your application Your connection will be Released when it is inactive for particular Time (The inactive time limit will be specified in the JCo Pool Settings that would be in milli seconds)
The RFC Connection can be Monitored using the Gateway process .
There are Some Predefined Connections in the Gatewway Process and each connection Requires approximately 200Kb of Memory.
So the memory cosumption of the Gateway process is proportional to the number of Active RFC Connection.
For More Details Check This

Closing window of web dynpro application with exit-plug don't run in the EP

Hi everybody,
I want to close a window that contains a Web Dynpro with a close button, because it's used and create as a popup from an other iView (that's not created with web dynpros) in the EP. I read the different threads how to close a window in web dynpro, like JavaScript in WD
I create a HTML file with the javascript code to close the window and it works fine, when I start the application separately.
If I used it in the portal and click the close button I get the following error message:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Exit-Plug must no be triggered with an URL when running in portal. Use portal navigation instead to navigate to another application!
I tried also: ...wdFirePlugExit("javascript:self.parent.close();") or some other javascript code, but got the same error message.
Then I tried:
WDPortalNavigation.navigateAbsolute(url,WDPortalNavigationMode.SHOW_INPLACE,(String) null, (String) null,(String) null);
instead of fireing the outbound plug in the action of the close button
(...InterfaceViewController().wdFirePlugExit(url);)
but than a new window with the EP open and the old is still there!
We use the NWDS2004s an the EP 7.00.
It must be possible to close a (this) window!
Thanks for any hint
christian

Hi,
This is what you can do:
1. You have already created the HTML file with the necessary javascript in the foloowing folder structure :
src->Mimes->Components-><your component name>-><fileName.html>.
2. Create a new iView of type URL in your portal.
3. Get the absolute URL of this HTML file inside your project. This will be in the following format:
http://<server>:<port>/webdynpro/resources/sap.com/<development ComponentName>/Components/<namespace>/<fileName>.html
You can find it thus:
try {
String u = WDURLGenerator.getAbsoluteWebResourceURL(wdComponentAPI.getDeployableObjectPart(),"filename.html");
wdComponentAPI.getMessageManager().reportSuccess(u);
} catch (WDURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
4. Now enter this URL string as the URL for the iview.
5. Do a normal portal navigation to this iview on-click of the button.

Satyajit.

Call another Web Dynpro with Configuration

HI to all
I have a Web Dynpro Components, and i have made Application configuration.
So I want call this Web Dynpro Application from an other Web Dynpro Application with the configuration I have made before.
Is this possible if so what have I to that this works, has some one a code example for me.
Thanks & Regrets
Hermann

Hi Hermann,
When you run an application with a special configuration, you may notice the additional URL-parameter
&sap-wd-configId=my_configid
. Just add this as a parameter to the application URL, and it will work.
Ciao, Regina

Call a ABAP Web-Dynpro-application via a BSP-Application

We have a BSP-Framework, that call several applications among other things other BSP-Applications, ITS-Application and other systems. Now I want to integrate a ABAP Web Dynpro-Application.
For the moment I can call the ABAP Web Dynpro-Application from our application.
This application runs in the same session as the Framework (verify in transaction sm04).
When I want to call another application in the Framework, the session will be killed (no more sessions in sm04). This happens also, when I want to call the ABAP Web Dynpro-Application a second time.
I guess, that the ABAP-Framework thinks I want to go outside the system (for example www.google.de) and close the session. I found out, that this wouldn't happen, if the application were suspended. But I found no way to tell the application via a url-parameter to suspend.
Can someone help me?

Thx for the tip,
but I can't firea suspend plug. Because I'm in BSP. I understand the docu so, that you have the option to call a other apllication like BSP from a ABAP Web Dynpro.
I want to call the ABAP Web Dynpro form BSP like this way.
1. Start BSP-Framework
2. Call ABAP Web-Dynpro-Application from BSP
3. Call another Application from BSP without automatically logout by unload ABAP Web Dynpro. (I have a chance to call the ABAP Web Dynpro again via url to suspend before I call the other app.)

Error - Creating a Web Dynpro Application Accessing ABAP Functions

Dear All,
we are trying to implement a web dynpro application with accessing ABAP functions.
Previous tasks:
- insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
- equipped the JCO connections with the web dynpro content manager (ping and test = OK)
Its the standard tutorial out of the SDN called Creating a Web Dynpro Application Accessing ABAP Functions.
Some hints:
- There are no errors after the implementation and the rebuild of the project in the NWDS
- The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager
- The In the build log I found these entries:

There two different URLs in use.
Start via NWDS:

Start via web dynpro content manager:

For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
Any ideas about the system behaviours (different URLs and missing functionality)?
Thanks a lot in advanced!

Web Dynpro Application Deployment need server restart?

Hi Everyone,
When deploying Web Dynpro application on production environment, do we need to restart the sap portal system and server?
I have this issue that when ever we deployed new develop Web Dynpro application with new Abap Function module we need to restart our Enterprise portal production server. Is this really necessary. Is there other way to deploy Web Dynpro application with new Abap function module without restarting the server.
Please help,
Michael Mondelo

Hi michel,
for example , assume you imported a RFC bapi_flights from r/3 to webdynpro dc , and both rfc requests and webdynpro application is deployed to the development server and then moved to quality server.
now you have done some changes in the rfc bapi_flights i mean change in the structure .
case 1 : now with out reimporting the change to webdynpro application and you move the request to the quality r/3, your application dumps . because the structure change is not incorporated at your webdynpro DC.
case 2 : you have re imported the rfc incorporating the changes to the web dynpro applicaiton dc, now with out moving the structure changes request to the quality r/3 and you deploy the webdynpro Dc having the changes to your quality EP , still the applicaiton dumps because your appliction refers to the rfc with out structure change in quality r/3.
case 3 : you have moved the abap request having the strucutre change and also the webdynpro development component where the changes are also incorporated , now on moving both , your application might dump , because the meta data cache might have been not updated with the new structure change in the quality ep server. so you have invalidate the cache in the JCos you have used to import the rfc. or else on restarting the EP server , the new structure change will be updated in the server.
most of the cases Invalidation of cache works and in some cases you have restart the server fo the changes to update.

Navigation Error in Web Dynpro Application

Hi All,
I developed a web dynpro application with 2 views.
I implemented the navigation paths(in and outbound plugs). I have a Next button in the first view and when
I clicked the next button it opened the second view.
It was working fine until, i created custom controller
and defined model node and model binding by calling RFC.
In the first view, i created a model node corresponding to the custom controller model node and defined the context mapping between the first view and the custom controller.
When I run the application (the first view displays data calling RFC) once I clicked the next button i got this error message.

Can anyone please tell me what is the reason for this?

Hi
Are you having any inputfields in your next view?If yes then check if you have bound the context attribute to it.
I think you haven't done that.

How to get User Id in Web dynpro application

Hi Experts,
I am running web dynpro application with authentication checkbox set. I want to display user id of the user in my application. I am using following code in Init method of component controller.
IWDClientUser wdUser = WDClientUser.getCurrentUser();
WdContext.currentContextElement().setUserName           (wdUser.getClientUserID());
Here I am getting some integer value as userId.
I am not using Portals, so solutions suggested for portal are not useful for me .
Is there any way to get this uset id.
Thanks in advance

hi
try this piece of code
          IWDClientUser wdUser = WDClientUser.getCurrentUser();
          IUser user = wdUser.getSAPUser();
          if (user != null)
                    IUserAccount[] acct = user.getUserAccounts();
                    if(acct[0] != null)
                              String strUserid = acct[0].getLogonUid();
wdContext.currentZtms_Fm_Regupdate_InputElement().setAssoid(new String(strUserid));
Note: Defining the IUser will show an error. To resolve this, within the properties of
the project, choose Java build path -> Libraries -> Add external jars ->
com.sap.securities -> lib -> com.sap.security.api. Open this file and retype the code.
