Webdynpro Application slowness

Hi everyone,
I am working in Netweaver 7.0
I have a webdynpro application which uses ARFC in order to execute a BAPI model object connected to the Action handler of a button.
The response, after the button is clicked for the firsttime , is taking a long time.
But once the response has been shown, the subsequent execution of the model object takes very less time.
Why is this difference?
Is there anything we can do to improve this ?
Share your ideas,
Thank you

Hi,
The following comments I will make is based on my experience.
As per your hyperlink, you would be right. Having "many" FM's per "Model" would be "best practice", but I think this takes into consideration only connection pooling.
In the real-world, this leads to inflated Models, barely re-usable, very 'costly' in Development Time, Build Time and Deployment Time. A fine tuning of JCO Connections is usually better than follow that (again, this is my opinion as a software developer).
Another thing you should be aware of is how the underlying layer works (JCO). If the Model has never been used (Not Cached!) it will take expensive time to build the metadata and modeldata into the destinations. As a 'work-around', (I've never did this, I'm not even sure if this would work) is to create a J2EE Application and 'read' the whole thing at server startup.
Also, be sure to be "caching" both destinations, this is a good 'performance' improvement.
Hope this information helps somehow,
Daniel

To get login details of portal into webdynpro application

Hi All,
How to get the portal login details(user name) into my webdynpro application.
Thank you,
Harsha P.

Hi,
If you want to have portal login details from backend system (with ABAP) you should ask this question in some portal forum and ask if it is possible. This has nothing to do with workflow or UWL. Even if you get the portal user ID to the backend system, then what? Do you want to manipulate the portal roles etc. from your ABAP WD application? Then you will have even more complicated requirements to achieve with ABAP. It is not that straightforward to call different portal functionalities from backend system. You might need to do some "portal development". And eventually your ABAP WD application might come just an unnecessary wrapper component for calling some web services or whatever in portal.

Needs a background webdynpro application running at the server side

Hi All,
We have a requirement wherein we need to have an application running all the time at the server side to capture the response coming from a web application. Based on the response that the application receives, it needs to update some backend R/3 tables.
We are thinking of a webdynpro java application.
Can anyone suggest what kind of application needs to be implemented here?
And what would be the steps required to run the application at the server side without calling the application.
Thanks & Regards,
Anurag

Hi Robin,
Thanks for the detailed explaination.
This may sound silly to you but I've another doubt which is as follows:
As you mentioned that the external web application will be sending requests to our Web service(in SOAP envelopes) and rest of the functionality can be achieved by our web service.
Actually, we are expecting only responses from the external web application. The thing is that we are sending the requests to the external web applications from our custom webdynpro application and in return the web application will be sending us 2 responses.
First response would be back to our WD java application URL(to the browser in which WD java app is running) which would get the response and display some message based on the response.
Second would be to this web service which you have just suggested. We are having two responses so that even if the browser in which the WD java application is running gets accidentally closed, the response from the external web application must get captured somewhere else and should not get lost in any case.
So, now since we are only expecting the response from the web application and we do not want any requests from the web application to our web service; how is this possible?
I am asking the above question because you have mentioned that the external web application has to request our Web service but we want is only this web service to capture the response coming from the Web application.
Or is it like the web application will send us the response string as request string to our Web Service and the web service will capture these response parameters as request parameters from the web application and do the further processing.
But in that case, we do not want any response to be sent by the Web Service to the external web application.
Please suggest if this is possible.
Once again, many thanks for the help so far.
Thanks & Regards,
Anurag

SSO b/w portal and webdynpro application customized login??

Hi,
I have one webdynpro application which has a login screen (Created as Webdynpro view). If user enters user/passord, the same gets checked from a custom table in the db (Method for checking user credtentials has been written in view controller). if user credentials are correct it performs some actions defined in webdynpro application.
I want to configure SSO b/w portal and this webdynpro application sothat when user logon to the portal and open this webdypro application, Login page of webdynpro application should not be shown i.e user credentials should be passed from portal and corresponding authentication method in webdynpro should be called to authenticate the user.
How to do the same without touching webdypro application ?
Can we call a method of webdynpro application from portal?
Regards
Deepak

1) To enable ticket authentication for the web dynpro iviews, you must maintain the definition of the system running the Web Dynpro application and set logon method to "SAPLOG"
2)Since you have customized login screen, you need to bypass this screen manually when you login from portal.
Add parameter to the application while defining the iview.Give some constant value.
Check value of this parameter in webdynpro and fire to next view.

How To Get GP Process Parameters in a Webdynpro Application runtime

Hi ,
Iu2019 ll hope you can help me to solve my problem with GP process.
Iu2019 m trying to get GP process parameters from a Webdynpro application.
I have to get parameters during the process runtime in every step of the process using
a webdynpro application with the following code:
      IGPRuntimeManager rtm = GPProcessFactory.getRuntimeManager();
      try {
            IGPProcessInstance processInst = rtm.getProcessInstance(processId,userContext);
            IGPProcessInstanceInfo procInfo = rtm.getProcessInstanceInformation(processInst.getID(),
userContext.getSAPUser());
            IGPStructureInfo inputstructInfo = processInst.getTemplate().getInputParameters();
            IGPStructure inputparams = GPStructureFactory.getStructure(inputstructInfo);
      } catch (GPEngineException e) {
            // TODO Auto-generated catch block
//          e.printStackTrace();
            manager.reportException("GPEngineException:"+getStackTrace(e), false);
      } catch (GPInvocationException e) {
            // TODO Auto-generated catch block
//          e.printStackTrace();
            manager.reportException("GPInvocationException:"+getStackTrace(e), false);
But printing the values of attributes with u201Cinputparams.getAttributeAs... ("param name")u201C the value returned is always 0. On the contrary if I check the same parameters structure in the runtime
GP view of the portal, the values are those that I have set in the start process wizard.
Have you a solution for this question?
Thanks in advance

hi Abhimanyu
I believe originally access to session was deliberately not made available inside WDA.
Growing security concerns due to misuse of session information and
perhaps other reasons as well.
X.509 is considered a better approach.
This may not help you in your problem.
But you may see a trend in WDA pushing more robust and client independent
approaches.
Full x.509 access should remove the need for session fiddling.
Also when developers access such session info directly, there is a possiblity
when they dont understand the technology exactly that they create a security hole.
You may know how to do safely, it is however discouraged.
Im not aware of a way to get at the session info inside the WDA framework.
Well not without a mod to the framework.
It may be possible without a mod, but I dont know the trick.
If someone has a little trick... please post.
You may need to use BSP, if your only solution requires access to the session info.
regards
Phil

Hi Experts,
I have a strange requirement ......
We have a Webdynpro Application which is connected to
say (using JCO connection)
client:- A
now i want to connect the same Webdynpro application to
Client:- B which is again in the same server as the client A.
Please help me how to handle this.
how it possible to connect a single Webdynpro application to two different clients using JCO Connection.
Please help.
Points would be rewarded to helpful answers.
Regards,
Sanjyoti.

Hi experts
                    We have to use wd application for both client at a same time e.g. as follow
Client A -

Storing the output of BAPI for further use in Webdynpro application

Hi,
In my webdynpro application, a BAPI_A is called multiple times from a backend.
All the previous outputs of the BAPI_A need to be stored in the webdynpro application as they serve as a complete set of input parameters for BAPI_B at the end.
Can anybody shed light on this temporary storage mechanism of the outputs of the BAPI_A.
Regards
Meesum

Hi Meesum,
Your BAPI structure
BAPI_A
--Output (0..n)
Field1
Field2
Field3
Field4
Value node structure
vnBAPI_A (0..n)
--vnResult (0..n)
vaField1
vaField2
vaField3
vaField4
1. Declare objVnBAPI_A (between begin and end)
2. Initialize in the vnBAPI_A in the wdDoInit()
3. After each execution of the BAPI (BAPI_A), create the vnResult and populate the fields of vnResult (from the BAPI_A --> output)
4. Add the vnResult object to objVnBAPI_A
Hope this should help you.

Calling a Webdynpro Application in using WDURLGenerator.getApplicationURL

Hi,
I have to call a webdynpro application in an external window using the application name. Please note that no iViews are created out of the application which i am going to call.
I have DC1 and DC2 and from the Comp Controlller of DC1 , i need to invoke the application in DC2.
String depObjectName =wdComponentAPI.getDeployableObjectPart().getDeployableObjectName();
WDDeployableObjectPart depObjectpart=WDDeployableObject.getDeployableObjectPart(depObjectName,"TestApp",WDDeployableObjectPartType.APPLICATION);
String url = WDURLGenerator.getApplicationURL(depObjectpart) ;
window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(url,"Test View");
window.show();
Is this the correct API to get getDeployableObjectName which is in the different DC.
Please let me know the correct API which i can use to get the getDeployableObjectName and the subsequently the Application which is availbale in the different DC.
Thanks and Regards,

Hi Chintan Virani,
Thanks for your reply.
Is it possible to get to know through the APis that the Webdynpro Application Deployed in the server is started.
I hope some API's will be available.I need to open this application only when it is started.
I tried this,
IWDDeployableObject deplObj = WDDeployableObject.getDeployableObject("TestApp");
if ( deplObj.getState() == WDDeployableObjectState.STARTED ) {
// do something

WebDynpro Application for WinMobile 6.5

Hi Experts,
Can anybody tell if there is an official SAP statement that WebDynpro supports or not Windows Mobile 6.5 devices? I can not find anything about that in the PAM.
WebDynpro supports the URL Parameter sap-wd-client=PieClient to render WebDynpro applications on mobile Devices (Pocket Internet Explorer in our case). Our application works fine on a 5.5/6.0/6.1 device but with view bugs on a 6.5 device (seems that using ParameterMapping on IWDButton and IWDLinkToAction is ignored).
Regards
Michael

Hello Michael,
Windows Mobile 6.5 device has to be certified and for this the customer vendors should contact SAP to get it certified.
So, new devices that come out with 6.1 and later versions shall be supported by SAP, provided the devices are certified. Certification will be on a "device-level".
So, all you have to do is to ask your device vendor to get the devices certified with SAP.
So, if a device vendor wants to get a device certified - then they can approach SAP. We shall do the testing and then certify that the device can run SAP NetWeaver Mobile client. So, it does not matter if the device OS is 6.0 or 6.1 or later. We shall certify the device, and then customers can run the application on the certified mobile device.
I hope this helps you.
Regards,
Blanca

WebDynpro Application issue consuming asynchronous webservice from SAP PI

Hello experts i ask you for help thie following issue:
i am developing a webdynpro application which is supposed to
send some data from inputfields, and a file, in order to achieve it, that dynpro application is consuming an asyncrhronous webservice , this service is running in SAP Process integration .it uses only a component.
Iam having serious problems at mapping the asynchronous PI web service model -->to -->controller >and then to->view
since when i deploy the application into the SAP portal´s application server, it runs , but inputfields cannot be written.i dont mean unabled, what i mean, is. cannot write anything on them.ECXEPT the file upload UI element.
I have reviewed sap help page, 3 sappress books, about dynpro, and the procedure i am performind is agree with them.
endpoint test answers the folloiwng:
Message Servlet is in Status OK
Status information:
Servlet com.sap.aii.af.mp.soap.web.MessageServlet (Version $Id: //tc/xi/NW04S_20_REL/src/_adapters/_soap/java/com/sap/aii/af/mp/soap/web/MessageServlet.java#1 $) bound to /MessageServlet

Lookupname for remoteModuleProcessorLookupName: null
ModuleProcessorClass not instantiated
ModuleProcessorLocal is Instance of com.sap.aii.af.mp.processor.ModuleProcessorLocalLocalObjectImpl0_0
ModuleProcessorRemote not instantiated
what i did is the same as before(in another projects weh i used to import rfc models):
1.- import webservice model,and add it to component
2.-map web service model to controller context
3.-map controller´s context to view context
4.-create actions and methods
5.-binding context controller to ui elements
Dear experts, my questions are:
What am i doing wrong?
should i permorm another steps because the web service is in another application server (SAP PI)?
Should i create a stand alone proxy and then access it from webdynpro?
when i call the web service model excution it seems does not run, neverthless the invocation does not have any syntax error , what coul it be?
Thanx in advance!!

just for the sake of other who may hit this thread , the solution is to add sap-client=<clientno> in the url for wsdl

Webdynpro application history navigation

Hi people,
I have a question about webdynpro navigation. I know that der are many threads
about this topic, but I think I don't find an answer for my question:
The scenario: I have a webdynpro application running in the enterprise portal.
The application is linked with ONE IView in the portal (and running on a different
application server). The application has about 20-30 webdynpro views, which are arranged
in different viewsets.
I need a navigation history (similar to the history in common web browsers like iexplorer)
in my application. Because of the multiplicity of navigation possibilities within the
application, it doesn't make sense to programm a static view navigation.
My question: Is there a standard way in webdynpro to realize my needs? Can I use the
PortalNavigation API, or is this API only for navigation between portal IViews? Can I
use the Breadcrumb Navigation UI Element?
I'm developing on a WAS 7.00 (Netweaver 2004s).
Thanks in advance for your effort,
regards,
Thomas

Hi,
You can use PortalNavigation. Take a look at the <i>historyMode</i> parameter of the <i>navigateAbsolute()</i> method. Find the documentation <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/56/b4544251dcc153e10000000a1550b0/frameset.htm">here</a>.
