Need to create a Web Dynpro Application for SRM Portal

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?

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.,

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!

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.

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

URL error while excuting web dynpro application for file upload in IP

The following error text was processed in the system DB1 : WebDynpro Exception: ICF service node for application /sap/public/bc does not exist
The termination type was: RABAX_STATE

Hello,
have you typed the web manually? try using transaction SICF and "test" the service so the URL is generated by the system. You should find the webdynpro application under /SAP/public/bc/
If the error continues re-import the transports.

hi,
i did the same thing den code is working and values are coming from the property file but i m going to place this application in the Internet.
There i can't ask user to enter User-Id and PWD.
I tried to use IWDClient's object and through this i m accessing getSAPUser().
here is the code that i m using:-
wdClientUser = WDClientUser.getCurrentUser();
manager.reportSuccess("wdclientuser-"+wdClientUser);-value is coming for that
sapUser = wdClientUser.getSAPUser();
manager.reportSuccess("sapUser -"+sapUser );Null is coming for that
//create an ep5 user from the retrieved user
ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
resourseContext = new ResourceContext(ep5User);
resourseFactory = ResourceFactory.getInstance();
pathRID =RID.getRID(/documents/IDBDevelopments/Propertyfiles/JobOpportunity/DateofBirth.properties");
resource = (IResource) resourseFactory.getResource(pathRID,resourseContext);
In that point i m getting Null as value.coz it's description says that if user is Anopnymous this function will return Null.
Coz of that i m not able to create Resource context for reading the property file.

Create iView for Web Dynpro Application

Hi guys,
I've created a Web Dynpro Application via NWDI and deployed to the j2ee server. Now, I'm trying to create an iView to link to that application. The steps I've done are:
1. Create iView for Web Dynpro Application
2. Select "Create iView from each application View"
3. Select my application.
That's when the error occurs at step 3. I select my application and click next, but an error msg keeps appearing telling me to "To continue, select at least one application" despite having already done so. Can anyone enlighten me on this? Thanks!
ZHenmin

Hi,
First make sure the applications runs fine standalone. Also the versions for WAS and EP are maintained correctly. Actually, this error seems to be occur for many users. Check this thread too.
Open new Web Dynpro iView in EP7
If nothing works, restart the server and try creating the iView again.
