The Domain of the WebDynpro Componenet

[Former Member]

Hi

I am developing a WebDynpro local DC i have a doubt while creating a DC

1)if see the Name filed drop down is greyed out where as next input filed takes only eight charecters, but if isee some the examples there is is entered more than eight charecters? is there any suggestions

2)in domain there are various domains which one i have to selct. Let's say i am developing a testWD DC which Domain

i have to selct, in case i am developing WD DC for some Customer how do i judge i have to selct htis domian only.

is there any relation between Domain and DC.

3) I have gone through the following Links

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/49f2ea90-0201-0010-ce8e-de1...

Here the tutorial only mentioned how to import and deploy and run, i followed all steps still i am getting following errors

Hi Murali,

Here are the answers:

1) The name field can take more than 8 characters. However if you read the message carefully it states that ".....The length over 8 signs is not recommended".

So you can have dc with a longer name but its not recommended.

2) Domain of the DC specifies ID of the development area (bank components, controlling, and so on) for which the new DC is to be created. Its like to specify the area for which you are developing the functionality.

3) Please let me know your WAS and NWDS version. Also tell me which tutorial were you testing when you encountered the mentioned error.

4) Here is the example you are looking for.

Hi,

Well, step by step:

1) create WD DC "utils"

2) create WD Component "Component1"

3) In interface controller define method or event or context strucure (here i defined a method sayHello)

4) Right click on "Component1", select "Add to Public Part". Specify name (Utils). Build DC.

5) create WD DC "component"

6) In Used DCs of "component" add public part "Utils" from component "utils"

7) create WD Component "Component2"

😎 Add used Component for "Component2". Click "browse..." and select Component1, specify name (Comp1UC).

9) Open view from Comopnent2 and add Comp1UC (Web Dynpro Component Interface Controller) as Required Controllers???. ( I am not getting this step)

Now you can call methods:

wdThis.wdGetComp1UCInterface().method(); (this code has to be in view of Component DC)???

Subscribe to events, and use context mapping with Interface Controller from Component1.???
