Poor performance of web dynpro application

Hi,
I have developed web dynpro application which fetches data from R3 system using JCO connection.Large amount of data is transferred between R3 and application,because of which it is taking too long for displaying result.
After displaying timestamp before and after RFC execution code I came to know that, it is taking approx. 5 min for RFC execution, resulting in poor performance.Time taken for rest of processing is negligible.Is there any way by which I can reduce time for RFC execution or data transfer?
Thanks in advance,
Apurva

HI Apurva,
I think u r displaying the whole data at a stretch in the front end. So it will take some time for rendring. So try to reduce the display elements (For example, for tables, display only 10 rows at a time).

Measuring the Performance of Web Dynpro Applications

I am trying to measure the performance of the ESS MSS WebDynpro applications. I am following the instructions at http://help.sap.com/saphelp_nw04/helpdata/en/bb/fdc4402418742ae10000000a155106/frameset.htm
but no performance data shows up for the ESS MSS WebDynpro components.
has anyone able to see any performance data for the ESS MSS WebDynpro components?
Thanks,
Tiberiu

Thanks Armin,
You are absolutely right.I have displayed all the 150 rows in the table on loading.This is the requirement which I should do for my Customer.(Displaying all rows)
If I give 40 rows to display,it takes 35 seconds to upload the file.But it takes 30 seconds to go to next page of table ,when I click Page Next property of Table.
Is there any way to reduce this display time.
Regards,
Dan.

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!

Error while accesing ABAP web dynpro application

Hi Experts,
We are getting warning symbol on web page status bar, when we are accessing the ABAP web dynpro application
only first page of application is getting loaded and when we click on page it is showing error on status bar and we can perform any thing.
once we double click on warning icon,
below details are coming:
Line: 1491
Char: 3
Error: Object Expected
Code: 0
URL: url of the ABAP web dynpro application
This scenario is occuring for many ABAP WD application for a client.
Please guide how to solve this issue?
Thanks!
Piyush

Hi
First try a very simple application with nothing in it just one text saying Hello World
Run it and see what happens.
Also check if your url uses FQDN name. something like https:
company.name.co:50000\.......
If you do not use the FQDN it will always show a script error on the bottom and some functions will not work e.g
dropdowns.

The Web Dynpro Application 'XssMenu' has expired

Hi,
we implement an ESS Scenario, with One Enterprise Portal 6.0 SP17, a mySAP ECC 5.0 System with ERP2004 and a seperate server with a java stack, because our customer don´t want to install and use a java stack on their HR/ERP systems. They want to minimize the performance.
After some configurations, we get the startpage for ESS. If I click on a service like travel management it has no effect. If I click the second time, I got an error "500 Internal Server Error" with the message
The Web Dynpro Application 'XssMenu' has expired. Please restart the application either with the refresh button or click the following link XssMenu.
Same error comes, if I choose travel management in the second navigation level and click the service. And same message on every service.
Now I tried anotehr way. I call the ess startpage directly on the external java stack. And here´s no problem. All WebDynpro-Services works fine.
Can anyone help me, why the WebDynpro Service doesn´t work in the Portal?
Best regards
Christian

We had exactly the same problem. We had multiple java servers and our switch was not retaining stickiness. So it would send the user to a different java server which hadn't got any session data for that user.
If this could be it, get something like httplook to do a trace of what is happening. We saw it switching java servers.
If you do not have multiple servers it could be switches chopping out cookies, causing the same issue.

Web Dynpro application does not apply portal theme

Hi Guys,
We created a new portal theme and assigned it to our users. The portal desktop gets assigned succesfully and portal applications also show the new theme colors. But all web dynpro pages still show in the blue SAP theme. This issue only occurs on our development portal, when we import the same theme on our test portal is all works fine.
I also tried to assign the WebDynpro parameters "sap.useWebDynproStyleSheet" and "sap.theme.default" and then the web dynpro applications are indeed forced into the portal theme. However, that is no soluition since all web dynpro applications then use the theme including SAP applications like the NetWeaver Administrator.
We looked at OSS note '1446099 - Web Dynpro application not displayed
in customer theme' but the stylesheets are not different.
sap portal sytlesheet: UR=7.31.0.14.1
Web Dynpro Style sheet: UR Version=7.31.0.14.0
The portals in which the theme does work have the same stylesheet versions as mentioned above.
We also created an OSS message for this so if we solve it that way I will update this message. But if there is anyone on this forum that might have an idea that it would be highly appreciated. If the problem takes too long to solve we will perform a refresh from a portal that works but I hope that we will be able to find the reason of this behavior.
Kind Regards,
Nico van der Linden...

In theory, these versions should work correctly.
You can compare the patch levels applied on your dev portal and test portal - specifically compare the version/patch for the component EPPSERV*.SCA - and see if you have any differences there.
Thanks,
Shanti

Problem deploying Web Dynpro Application Definition

Hi,
I have written a Web Dynpro and then deployed it to an EP6 NW04 server without first defining the Web Dynpro Application (silly me, I know - how could I do such a thing?). Anyway, afterwards, I created the Web Dynpro Application definition, but no matter how many times I redeploy, it does not add it to the Web Dynpro now sitting on the server.
Können Sie mir bitte helfen?
Martin

Hi
Martin,
Although server is being maintained by third part(one option is though visual admin since you can't access it) other option is use youe web browser with url http://your server IP address:50000/index.html u will find webdynpro link as mentioned below
Web Dynpro
Web Dynpro is a User Interface technology available within the SAP NetWeaver Developer Studio.
Various Web Dynpro tools provide administrators and application developers with performance measurement and application administration capabilities. The Web Dynpro runtime is already deployed.
Now Click on Web Dynpro link
you will find Content administrato and web Dynpro administrator u will b directed to login page after entering with UID and passwd u can see all deployed applications ( u can check ur application) and details...
I hope this may help u..

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>");

Amr Azim,
You must have logged in thru a dedicated connection to any server through say VPN before deploying.This way the sdm uses the same login as that of already establised connection.
So 'sign of' all connections to any servers before deploying and redeploy your application.Here you will be prompted to supply the sdm password and deployment shall proceed.

I have checked this error description in ST22 :
What happened?
    The exception 'CX_WDR_RT_EXCEPTION' was raised, but it was not caught anywhere
     along
    the call hierarchy.
    Since exceptions represent error situations and this error was not

Error analysis
    An exception occurred which is explained in detail below.
    The exception, which is assigned to class 'CX_WDR_RT_EXCEPTION', was not caught
     and
    therefore caused a runtime error.
    The reason for the exception is:

Looks to me like you are trying to fire a navigation plug within WDDOMODIFYVIEW. According to the rules of the WD Phase Model this is not allowed.

Error while implementing a web service in web dynpro application

HI All,
I am trying to use a webservice in a web dynpro application.
Web service description:- This is a very simple application which takes two String inputs and when submitted displays the string in the concatenated form.
Web dynpro:- I used this web service in the web dynpro as an adaptive web service model.
The Layout design consists of two input fields which are mapped to the request fields
ex : - Request_Add.Add.S1 and Request_Add.Add.S2
A text area to display the response:- Request_Add.Response.AddResponse.Response
And a button which invokes the execute method
public void onActionWebserviceCall(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
 //@@begin onActionWebserviceCall(ServerEvent)
 wdThis.wdGetWebserviceCompController().executeRequest_Add();
 //@@end
When I am trying to run the application I am getting error:-
Exception on execution of web service with WSDL URL 'http://<Host>:<Port>/EjbWebservice/Config1?wsdl' with operation 'add' in interface 'EjbWebserviceVi_Document'
Kindly reply.
Thanks

Hi,
Yes I have tested the web service in Navigator . The WSDL is also properly generated.
I have not publish the web service in UDDI but as per my understanding this is not necessary. please correct me if I am wrong.

Hi Neha,
It seems that there is problem with your SDM server. It seems that during J2EE engine configuration SDM server is not configured. Actually this configuration is done by Basis Team.
By the way try out your Server setting:
Go To:: Windows -> Preferences -> SAP J2EE Engine
[Mention the required details over there]
And Check whether you are getting Active SDM Server under J2EE Engine.

At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
"http:
<hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
Provide those details in the NWDS.
