Creating a Web Dynpro?

I am new to Web Dynpro. I am trying to create a simple Web dynpro following an SAP tutorial.
The directions are as follows:
step 1)In this step you first create a new component. To do this, call the Object Navigator and choose Web-Dynpro-Comp./Intf in the object list.
I do not see "Web-Dynpro-Comp./Intf " in the object list? I am in SAP version ERP Central Component 5.0.
However, I can select "edit object" and go to Web Objects tab and create ZMYCOMPONENT that way. But when I do, I cannot perfrom the second step below for selecting the component controller, I do not see it.
step 2) Now double-click on the ComponentControllerobject of your new component. The Context tab page of the controller is automatically displayed, and you now have the option of defining a context. Make sure that the Workbench is in change mode.
Thank-You

Hello,
WebDynpro ABAP was delivered with NetWeaver 7.0. So you would need to be running SAP ERP 6.0 or ECC 6.0 in order to use it. ECC 5.0 runs on NetWeaver 6.40, so it is not available for you. However, NetWeaver 6.40 does support Web Dynpro Java, but that most likely will not help you.

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!

How to create a Web Dynpro Project from Downloaded zip file?

Hi,
I have been working in Java Web Dynpro for last 1 month but not able
to create any Web Dynpro from Downloaded zip file?
Can anybody tell me how to create a Java Web Dynpro Project from
Donloaded zip code?
Regards
Kaushik Banerjee

Hi Kaushik,
You can add the existing zip file into your workspace by the following way -
First open the NWDS and create a new project by clicking file -> new -> Project -> Simple -> Project
and then File -> Import -> zipfile and then browse the zip file into the newly created project.
or else you can also unzip the zip file into a folder and then Use the option of Import an exisitng project into workspace. You can find this in the File-> import -> Existing project into workspace. and then use the Browse option to browse to the existing folder.
After importing the project you need to rebuild the project

Problems with tutorial: "Creating a Web Dynpro Tree"

Hi!
I'm a rookie and therefore I'm practicing on compleating some tutorials like "Creating a Web Dynpro Tree" (https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f0ec6622-8da5-2a10-349b-868b6a553efa)
I did just as the tutorial told me to (I think) but still I get a java.lang.NullPointerException when I deploy and run my application.
In the bold line is where it is something wrong:
public static void wdDoModifyView(IPrivateTreeView wdThis, IPrivateTreeView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
    //@@begin wdDoModifyView
       if (firstTime) {
            IWDTreeNodeType treeNode = (IWDTreeNodeType) view.getElement("TreeNodeType");
            /* parameter mapping from parameter "path" to
parameter "selectedElement"
            treeNode._mappingOfOnAction()._addSourceMapping("path", "selectedElement");
            /* parameter mapping from parameter "path" to
parameter "element".
            treeNode._mappingOfOnLoadChildren()._addSourceMapping("path","element");
    //@@end
What I don't understand is what the function/meaning of the parameter path is. The parameters selectedElement and element I do recognize and have written. And I don't understand why there is a difference between the two underscored line of code (see above) even though the comments claim that it does the same kind of mapping.
Best regards
/Johan

I tried to get "addSourceMapping()." underscored so people would better understand what I was referring to but it didn't work and that's why it looked weired.
Thanks for your help Armin, now it works fine.
It was as you said.
if (firstTime) {
IWDTreeNodeType treeNode = (IWDTreeNodeType) view.getElement("TreeNodeType");
When I changed "TreeNodeType" to it's real ID, "TheNode" I didn't get a nullPointerException. I think it must be wrong in the tutorial because I followed the instructions which said to name it "TheNode" but then the author mus have forgot to change it from the default ID ("TreeNodeType").
Best Regards!
/Johan

The test performs the following:
1. Checks the validity of the system ID in the system object.
2. Checks if the system can be retrieved from the PCD.
3. Checks if a SAP system is defined in the system object
4. Validate the following parameters: WAS protocol; WAS host name
5. Checks if the host name of the server can be resolved.

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

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.
<b>my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme</b>
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
<b>my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme&sap-wd-client=PieClient</b>
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

Problems creating new Web Dynpro ABAP application

All,
I am following this tutorial to create my first Web Dynpro ABAP application
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/fc/501b42b5815133e10000000a155106/frameset.htm
In this tutorial I was asked to create a component as Local object.
But after giving the name of the component, I get an alert saying
"Object can only be created in SAP Package"
When I confirm this, I was shown a "Create Object Directory entry" dialog box which asks for attributes like Package.
And this box has Local Object button, when clicked I get the message "Test Objects cannot be created in foreign namespaces".
I found some other article through Google
http://www.octavia.de/fileadmin/octavia_files/content_bilder/Hauptnavigation/SAP_NetWeaver/WebDynpro/Web_Dynpro_Part_I.pdf
According to this, I tried to give $TMP as Package. But still have the same error
"Test Objects cannot be created in foreign namespaces"
Where am I and what should I do to create a new project?
Thanks.

Thanks Abinav.
My problem is with naming convention only. Component name starting with Z solved my problem.

Created in Web dynpro Java or Web dynpro ABAP

hi all,
I have a web application running. Its UI is created either in web dynpro java or web dynpro ABAP. Is there any way by which we can find out that in which form of UI technology is it created; in web dynrpo java or web dynpro ABAP ?

Hi,
I am really not sure if this is recommended..
Try some negative testing on the application. If the application crashes, the trace of the error occured will tell you what kind of development has been adopted for the Web Dynpro application.
Another hint can be the port number in the Application URL. If it is not 50xxx, and is somewht like 8xxx, it is surely Web Dynpro for ABAP.

Alka.
