How to transform Webdynpro Project to use Library DC

[Former Member]

We developed our project as Webdynpro(JAVA) project beforehand. However, with the growth of our libaries, the deployment time becomes unbearable. The reason is that the Webdynpro project doesn't support library as DC and therefore upload the whole jar datas onto server every time.

Our plan is to repack all the libraries into a library project and publish it on the server beforehand. Therefore we need only upload other normal java classes for each new deployment.

However, how to let the current web dypro project to use the library project?In other words, how to transform our web dynpro project to let it support referencing library DC?

Any advices will be very welcomed!

I add dependency on the library DC with both "Compiliation" and "Assembly" types. And the webdypro DC is now compiled successfully.

However, during the deployment (select "Deploy New Achieve and Run" in the Webdynpro DC), I got following errors.

I use NWDS 7.1 and JDK 1.5

Zenghuan,

Try doing just DEPLOY of the DC and then check your application thru Portal or complete Dynpro URL.

@Chintan,

The error already happened during the "Deploy" phase. Besides, there's no "Deploy" option in the context menu, only "Deploy new Archive and Run" is available in NWDS 7.1

I'm afraid the error lies on the fact that I already deployed a normal webdynpro project on the server before. Since the Webdynpro DC project is no other than a copy of the old project, there are maybe some conflicts.

Now I tried to create another instance on the server (with other port) and deploy the DC project on the new instance. However, I don't have much experiences on creating instances on Netweaver AS. Could you offer me some advices or links?

Hi Zenghuan,

Follow the Steps

-

---

1> Right Click on the web dynpro project

2> Select Properties

A Properties wizard will appear select

<b>Project References </b> from the left hand side pane and check your external library DC from the right hand side pane.

3> Click on OK.

4> Generate Application, Build Application and Deploy Application

Regards,

Mithu

Hi Zenghuan,

You are right if you are using latest versions EP server.

Check this wiki for more details.[wiki |https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/clusterwideexception-FailedtodeployWebDynprocontentforapplication&]

Hi Siva,

In your suggested blog, there's a step to rename all components. What should I do? Should I rename the component directly? If I do so, I get many error messages which I can't even understand. (I use "Refactor -> Rename" by right clicking on the old component name .

"Runtime exception occured while executing job "Refreshing repository state for resources": Attempted to beginRule F/warp2/src/packages/com/sap, does not match outer scope rule:

com.sap.ide.dii05.util.internal.job.InternalJdi$JdiLock@7e9f32"

Maybe the best way is still to create a new instance on Server....

Thank you for your suggestions, I now do like following:

1. Covert the normal Webdynpro Project to Webdynpro DC project

2 Create a Library DC project to hold all the jars as library

3 Add dependency to Library DC from the Webdynpro DC

Hi

Create a library DC and expose public parts, use this DC as a used DC in Webdynpro project.

Hi,

In order to convert your Web Dynpro project to DC, copy the src folder of your Web Dynpro project to src folder of DC.

Once you have converted your Web Dynpro project to DC then you can add/ use Library DCs in it.

Zenghuan,

You will need to convert your local project to a WebDynpro DC and create a Library DC for all your libraries.

Pls go thru below links for better understanding of same:-
