Problem in creating a web dynpro application in netweaver developer studio.

Hi,
I have installed Netweaver developer studio. while creating a webdynpro project by selecting File->new->project, It doesn't display "web dynpro" option in the project wizard dailogue box.
Please suggest how to resolve this issue.
Thanks.

Hi Babu,
Make sure following plugin folder
"com.sap.ide.webdynpro.ui_xx.yy.zz(for ex:com.sap.ide.webdynpro.ui_2.0.0)"
exists in your ecclipse root folder (for ex:C:\Program Files\SAP\IDE\IDE70\eclipse\plugins\)
It is responsible for the UI selection elements in File->New Project->WebDynpro selection.
If it's not there you will have to copy it. check also other webdypro plugins installed correctly. these plugins comes with default installation of SAP WEBAS.
if all plugins not installed then redo the whole installation but at the same time make sure all plugins installed correctly.
reward points if usefull
Thanks

Problem of Creating a web dynpro application based on a car rental web serv

Based original SAP developer studio examples shipped with the developer studio, I first create J2EE application QuickCarRental. It works at http://192.168.254.4:50300/QuickCarRental.
A web service QuickCarRentalWebService is defined in J2EE application QuickCarRental. My web dynpro application TutWD_CarRental is web service consumer invoking QuickCarRentalWebService.
When I deploy TutWD_CarRental on SAP J2EE engine and run the application at http://192.168.254.4:50300/webdynpro/dispatcher/local/TutWD_CarRental/CarRentalApp, i can see the web dynpro web application interface right.
however, I get the following error when I input some data and Click button rent a car.
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (404) Not Found.
when i click Display all bookings, the error is:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (404) Not Found.
I install SAP developer studio on my winXP desktop, and the SAP developer studio version is 2.0.10.
I have my SAP Web application server and J2EE engine Version 6.40 run on a different machine. the SAP server IP address is 192.168.254.4
could anybody give me some clue on this. is that because i miss some configurations on SAP server for enabling web services of QuickCarRentalWebService?
Thanks!

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:

- Im able to start the application out of the Web Dynpro content manager with run => only the user interface is displayed without any functionality
- The normal start over the NWDS fails => error text
com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/J08_Flugdat_Daventdcflight~xxx.com' and application 'FlightListApp' are not deployed on the server. Please check the used URL for typos.
There two different URLs in use.
Start via NWDS:
http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
Start via web dynpro content manager:
http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
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!
Best regards
Christoph

What to after Creating a Web Dynpro Application

Hello,
My question might a little stupid so please don't mind. I have created a web dynpro application where the user enters a sales order no and the output of is shown in an ALV format in web dynpro. My question is what next, I mean how do I give it to the users to use it. They should only be given the URL which is generated?
Also if i directly enter the URL it asks me for my Username Password of the SAP Logon. can this be avoided like some reports where one cant make any changes in the database just get the output this Username Password thing be skipped

Hi.,
You can create a Transaction for Web Dynpro Application to dispaly in browser as well as in SAP GUI.,
check this: can we create a tcode for webdynpro application?
else you can integrate it in Portal by creating iviews.,
check this article: [How to integrate Web Dynpro ABAP in Portal|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/008fc414-997f-2e10-3899-fd895ec8eb5e]
hope this helps u.,

We need to recreate the start page for SRM Portal - (Supplier Self-Services) - without any images (as was delivered out of the box) - basically we need to break it down into 4 iViews: All Purchase Orders; All Sched Agreement Releases; All Invoices and Credit Memos; and Account History. All these iViews contains links.
How would one create a Web Dynpro Application to create the above iViews?

Problem in Closing a web dynpro application

Hi experts,
I wanted to close the application when the user clicks on the close button.
I created a out bound plug "EXIT" of type 'EXIT' in my window.
I also created a parameter "CLOSE_WINDOW" of type "WDY_BOOLEAN" for the outbound plug
Now in action of the close button i have done the below code:
DATA: l_ref_ywd_maintain_catalog TYPE REF TO ig_ywd_maintain_catalog .
l_ref_ywd_maintain_catalog = wd_this->get_ywd_maintain_catalog( ).
l_ref_ywd_maintain_catalog->fire_exit_plg( CLOSE_WINDOW = 'X'
where ywd_maintain_catalog is my window name.
when i check the program i am getting the below error:
get_ywd_maintain_catalog_ctr is unknown or protected or private.
I refered the standard web dynpro component "WDR_TEST_EXIT_PLUG" to implement the logic
Pls help
Regards,
Vinod

Hi all,
This is my requirement when i click on a close button the application should close.
i refered to a web dynpro component "WDR_TEST_EXIT_PLUG" where they have explained the way to use exit plug.
They have created a outbound plug in the window called "EXIT" of type exit. and in the action of the button they have used the below code to fire the outbound plug.
method onactionfire_exit .
data: l_ref_wdr_test_exit_plug type ref to ig_wdr_test_exit_plug .
l_ref_wdr_test_exit_plug = wd_this->get_wdr_test_exit_plug_ctr( ).
l_ref_wdr_test_exit_plug->fire_exit_plg(
url = 'http://www.google.de/'
endmethod.
I followed the similiar approach in my code:
I created a out bound plug "EXIT" of type exit in my window.
then in the action of the close button i have done the below code:
DATA: l_ref_ywd_maintain_catalog TYPE REF TO ig_ywd_maintain_catalog .
l_ref_ywd_maintain_catalog =wd_this->get_ywd_maintain_catalog_ctr( ).
l_ref_ywd_maintain_catalog->fire_exit_plg( CLOSE_WINDOW = 'X'
The problem i am facing is i am getting the error "method get_ywd_maintain_catalog_ctr is unknown or public or private"
I am referred to the below URL to do it :

Creating mobile web dynpro application which customized theme

Hi guys,
I have created a mobile web dynpro application and a theme with Theme Editor. Then I have appended this theme with the sap-cssurl parameter to my application.
my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme
It works well in my first testing on my laptop.
In order to test it on my mobile device I have also appended sap-wd-client parameter to my application. Now my URL looks like
my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme&sap-wd-client=PieClient
It doesnt work. My application layout looks as if I dont use the theme. Did somebody have the same problem and can help me by finding a solution.
Thanks for your answers.
Marita

Hi Marita,
Mobile Web Dynpro supports several handheld mobile devices. I guess yours is a Pocket PC. Except the newest Pocket PC 2003, all the other versions don't have CSS support. Therefore the current Pocket PC client "PieClient" of Web Dynpro lacks the ability for customized themes. On the other hand, themes are supported for more advanced devices, such as Nokia Communicator 9500/9300.

Wei

Problem with starting the Web Dynpro Application

Hello,
I have a problem with my web dynpro application, which is in our SAP Portal. We have three different systems (development, test, production). In production always the follewing error message occurs:
The URL https://zsil2401.servers.wacker.corp:9004/sap/bc/webdynpro/sap/ZPLM_EN_FORM_300MM/ was not called due to an error.

Some User get this message also in test an development. What could be the reason?
Note: Nothing has changed in coding or context.....this error occurs without any changements
Thanks for your help
Best Regards
Martin

Hi,
May be you can put an external breakpoint in the method "_get_attribute_rtti"(of class CL_WDR_CONTEXT_NODE_INFO).
From that you can find out which attribute is causing the dump , and try to solve the issue . May be some data dictionary object is not transported to production.(Assuming that you have permission to put breakpoints in production system..:))

Build Web Dynpro project EAR without Developer Studio

Is it possible to build Web Dynpro project EAR file without Developer Studio? All possible solutions are welcome (console, scripts, java etc.) I want to integrate the project into CI Server and try to find way for automatic build.
Thanks.

Yes. Sure. But as i can see, during generation of EAR there are some files like (Project)App.xml, (Project)Component.xml that regenerated each time i create EAR from Developer Studio. I don't know the logic of creation of these files. Is there standard ant build script from SAP which i can use?

Authorization Missing error while creating web dynpro Application

Hi experts,
I am new to web dynpro and trying to learn it by myself. I am getting an authorization error while creating a web dynpro application. I am not getting any errors while activating Views or Windows. But when I created a web dynpro application and tried to save it, it thew me a warning saying that " You are not authorized to use function Netzwerkadministration " . Still I could be able to create the application, but not able to run it.
What settings should be done to have this authorizations ?
Any suggestion would be helpful.
Thanks,
RVSS

Hi,
Get your BASIS person to give you authorization to Tcode SICF and also authorization to create and activate services in Tcode SICF.
You need authorization to object S_ICF_ADM apart from authorization to tcode SICF

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?
