thanks

That's really weird...your screenshot is missing the part of the screen where you define which kind of object you want to edit (and it's name). It's there where you must select "Web Dynpro comp./intf" and enter the name...it should be right below the "Test Repository" pushbutton...
Maybe it's a SAP GUI issue...i'd try reinstalling

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

How can i do?
Thanks

Hi,
There is something wrong in the definition of component usage in your component. Maybe you forgot to instantiate the use component, maby the name you are using is not correct. Try to find it in that direction.
Good Luck,

Web dynpro component interface, can't create a instance

Hi guru,
I have created a web dynpro component interface, and implemented it through some components.
But when I use the interface in another component, there comes a runtime error. The following is the error message.
Error when Creating Component YHREFM_OBJSEL_INTERFACE. YHREFM_OBJSEL_INTERFACE Is a Component Interface, Therefore, an Instance Cannot Be Created. Name of Component May Not Be Specified. (Using Component: YHREFM_PRINT_FORM_SE, Component Usage: USAGE1)
Need your help!
Best Regards,
Guo Guo Qing

Hi,
I have found the cause of the problem. I have mapped some context in the component interface to componenet_A. Then I active component_A, and test it. Then the exception on the top of the Thread is raised.
What's wrong with it? Could someone give me a solution?
Thank you very very much.

No component usage created in enhanced web dynpro component

Hi experts,
I am facing the following problem:
I'd like to enhance a web dynpro component in order to add a popup window. The popup is triggered by the process_event method. So far everything works just fine.
But the popup needs to know some context attributes from the main component, and I cannot create a component usage in order to set the context mapping.
Does anybody know how to solve this issue?
Thanks and regards
Jan Phillip Höft

Hi!
Thanks for your answers first of all.
I need the popup to be a stand alone web dynpro component, so I guess the assistant class doesn't do the trick because I can not access it in the popup component.
The popup is called when the business object is saved. So that the user is asked to notify other users that the document has changed. In this popup the user should fill in the message and click a button to send it and close the popup.
So I tried the OBN approach as well but with two problems :
1. I cannot close the popup component by coding (button click) because it has no direct parent component
2. The save event is not run through properly so the document stays locked by the user. But I didn't look into this yet.
So it would be perfect to have an embedded popup component which is based on a stand alone web dynpro application so it can be closed properly but it need at least access to the guid of the main component.
Anybody got an idea for this?
Thanks and regards

How can we call methods of one web dynpro component in another one

Hello Team,
How do I call one Web Dynpro component methods in another Web Dynpro component.
How do we use public parts.
thanks

Hi,
You want to use Comp2's getData() method in Comp1
If both the WebDynpro components are in the same DC:
1. Create a wrapper method (with the same signature) in the Comp2's Interface controller. And invoke the Component contorller's getData() method in this method using the below code.
wdThis.wdGetComp2Controller.getData()
2. Now Go to the Comp1 and right click on UsedWebDynproComps and add this Comp2 as a UsedWebDypro component.
3. Now go to the Component Controller of Comp1 and in properties tab add the usage declaration of Interface controller of Comp2.
4. Now using this below code you can access the method of InterfaceController of Comp2.
wdThis.wdGetComp2Interface().getData();
If both the WebDynpro components are in different DCs:
1. Right click on Comp2 and select Add to public part on Comp2 in DC2.
2. Now Add this public part in DC1 UsedDCs.
Now repeat the above stpes 1...to..4. of "If both the WebDynpro components are in the same DC" same.

Calling session bean's business method through web dynpro component

Hi All,
Can anybody tell me how to call a session bean's methods through a web dynpro WITHOUT java-model or web service model ??
I have following scenario:-
1. Stateless Session bean having two business methods
2. Web Dynpro component
3.Now i want to call business methods without using any model. I have got following piece of code but I dont know how to go about it.
4.Where do i have to set JNDI name for session bean? which interface will be looked for?
5. Do I have to declare public part for EJB DC? If yes, how?
//This is inside web dynpro component
InitialContext context = new InitialContext();
o = context.lookup(JNDIName);
TestSessionbeanHome homeRef = (TestSessionbeanHome) PortableRemoteObject.narrow( o,
TestSessionbeanHome.class);
TestSessionbean beanRef = homeRef.create();
<returnValue> = beanRef.<ejb method name>
Please help to get a step-by-step approach to this case.
Thanks and regards,
Amey Mogare

Hi,
If I comment out the part that is using session bean's business method, DC is building fine.
And if I uncomment, then compiler is unabl eto resolve business method(s).
And i would like to mention that my EJB + J2EE App DC is building properly, but it havent yet deployed properly as I am waiting for data-source-alias name prefix to be configured by ERP team. So will this be a reason why Web Dynpro DC is not able to resolve business methods ??
Because Web Dynpro DC is able to resolved all interfaces of Session bean and entity bean. But when it comes to business method, its not able to resolve.
Any more ideas why it is not happening?
Pls help.
Now i went through some forum posts regarding this and found that we also need to add EJB DC to Java Build Path for WebDynproDC>Properties>Java Build Path.
I did this and now it is able to resolve business methods and DTOs as well. So to summarize I did following:-
1. Added EJB DC (complete DC) as a Used DC to Web Dynpro DC with Buid-n-Deploy-n-Run time dependency
2. Added Sharing reference of J2EE application DC to Web Dynpro DC -->Properties
This reference I constructed as follows:-
<vendorname>/<name of j2ee application as appearing under display name tag in application.xml (replacing '/' with '~')>
So my Sharing Reference becomes:- <vendorname>/reqpstapscreqpstapja_reqid
3. Added EJB DC to Java Build Path in Web Dynpro DC's properties
4. Then I added following piece of code to get object of SessionBean class
InitialContext context = new InitialContext();
Object o = context.lookup("java:comp/env/ejb/SessionRequestIDBean");
SessionRequestIDHome homeRef = (SessionRequestIDHome) PortableRemoteObject.narrow(o, SessionRequestIDHome.class);
SessionRequestID beanRef = homeRef.create();
beanRef.<business method>
But After doing this I am facing another problem :-
The build fails saying it is not able find the package for DTOs. But when I see the Component Controller's code it is not showing any red or yellow marks.
Can anybody pls help me out here?
Thanks and regards,

Context from Web-Dynpro-Component-Interface & Customer Extention Fields

Hello all,
A main component uses a Web-Dynpro-Component-Interface and defines an external maping to it. Web-Dynpro-Component-Interface has a context and a window. At runtime implementaion of Web-Dynpro-Component-Interface is provided.
All works fine, but how can i create an implementation with view which contains customer extention fields? Unfortunately only fields from context of Web-Dynpro-Component-Interface are visible. I can not even extend the context of Web-Dynpro-Component-Interface via enchancement framework.
I assume, it is possible with dynamic programming, but why is it not possible in declarative way?
thanks
regards
Paul

Hello,
I found this documentation:
Implementation of Interfaces for Customer Developments
Using interfaces in a Web Dynpro component benefits customers by giving them a clean basis for their own further developments. When creating a local development, you can implement a used interface in a separate component and add your own aspects to an application delivered by SAP.
http://help.sap.com/saphelp_nw70/helpdata/en/a9/19eebc1e2943dbb2d443095d017ae9/content.htm.
I think it must be a correct way to extend SAP programms with customer fields. Please reply, issue is very important.

Paul

Dynamic Use of web dynpro component

Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.

Doubts while doing example on WDJ-Using Web Dynpro Component Interface

Hi
I am doing the example mentioned in the PDF file WDJ - Using Web Dynpro Component Interface Definition.
In the PDF file its mentioned the following code inside onActionCreateDC1:
g_Usage.createComponent("com.sap.wd.childdc1comp.ChldDC1Comp");
wdThis.wdGetWDCompInterfInstInterface().passInfo(
"Created Child DC 1");
I have one query that what is com.sap.wd.childdc1comp.ChldDC1Comp?Is it the component name of DC or the package name of DC?
I have deployed the application.When i click on button Create Child DC1 i am getting follwing exception:
com.sap.tc.webdynpro.services.sal.deployment.api.WDDeploymentException: Failed to load deployable object part 'com.wartsila.test.ChileDC1Comp', type 'Component' of deployable object 'wartsila.com/DP_TutWDInterfaces'.
When i click on Create Child DC2 i am getting follwing exception:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException:Failed to create delegate for custom controller com.wartsila.test1.ChildDC2CompInterfaceCfg. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)
Can anybody tell how can i solve it?
Is it required to deploy the two child component also that is ChildDC1Comp and ChildDC2Comp?If yes then how to deploy these two child DC as when i am tryng to create application for these two component then default plug is showing blank thats why i am unable to deploy these child Dcs.
Thanks
Susmita

Hi Susmita,
Is it required to deploy the two child component also that is ChildDC1Comp and ChildDC2Comp?
Yes , u have to deploy both the components.
when i am tryng to create application for these two component then default plug is showing blank thats why i am unable to deploy these child Dcs.
U need not create an Application for deploying the component .Right Click on ur project --> Deploy.
The problem is with ur Component, while creating a Component u should have created a Interface view and default StartUp plug.
Just check whether u have Created the startup plug for ur interface view.
Open the controller editor of ur interface view --> Select Plugs Tab .
and in the plug tab , check whether u have Default Start plug (in Inbound Plugs Table).
if there is no Default Start Plug , then click the Button New to create a Default Plug .
in the pop up window -- select Stsrt Up and Give the name of the plug as "Default".
After doing this , select the default plug and Right click on the plug -->copy and Open the window Controller editor -- > select Plugs Tab --> check whether u have default plug (in Inbound plugs) in the Window controller .
if the plug is not there , then paste the plug in the Window's Inbound Plug Table .
Hope it helps
Thanks and Regards
