WebDynpro quastions

[Former Member]

Hi all,

I need to know:

- In order to use WebDynpro, SAP portal is needed or only ICF and ICM?

- controller context variables can have a scope like session, application or request ?

Thanks in advance,

Hi ,

webdypro for abap needs just sap portal since we already have repository and we need not hav any j2ee engines installed in it.But we need to make some configurations in system 32 for browser settings..

Controller context it is something like global definations..since it is backbone of all components it can mapped with other contexts like to other views context.this terminology is for webdynpro for abap again if it is for webdynpro for java then we need to have sap netweaver installed into our system ..

Hi Sana,

Thank you for your answer!

I think that SAP portal is a great effort prerequisite in order to use WebDynpro. Don't you think? I mean if my customer has a SAP standard installation, in order to use Webdynpro in my project I have to ask a new installation.

Can I ask you another question?

Can I translate a WebDynpro for JAVA in a WebDynpro for ABAP easily? Or They are completely different objects?

Thanks in advance,

Hi Piercarlo,

No using web dynpro doesnt take much effort since we nedd not make much configuration than compared to java webdynpros. since we have se80 there in abap .If ur customer wants webdynpro then no need of new installtion but make sure tht webdynpros work only frm Ecc6.0.sap gui as 7.that is mandtory rest all will be simple while compared to webdynpro for java since we need to ge installed with sap netweaver,.

NO there is no such tool for converting .Webdynpro for java to webdynrpo for abap they are entirely different objects..

and i am sending u some links where in u can feel tht webdynpro is quite interesting.Check these links...

Hi Sana,

I'm sorry for the late reply.

What do you mean with: "compared to webdynpro for java since we need to ge installed with sap netweaver"? I know that from 640, every SAP system needs the installation of SAP Netweaver.

Besides on official "WebDynpro for ABAP" configuration guide I see the only prerequisite is Netweaver. SAP portal is not a prerequisite for WebDynpro.

Webdynpro for java to webdynrpo for abap they are entirely different objects. But is there a different repository for java objects?

Thanks,

As far as repository's for WD ABAP versus WD Java go...

WD ABAP is handled entirely on the ABAP stack, edited via SE80 and managed with the normal transport management system.

WD Java on the other hand can have 2 main forms - local where the objects are all held on the developers local machine within their NDS workspace; and via the NWDI (Netweaver Development Infrastructure) which is a J2EE implementation similar to the TMS, with CVS type functionality. It allows team development and transport and change control of Java type objects, including Web Dynpro. In both cases the local and remote developments can be built and deployed to DEV, QA and Prod Java stacks but the NWDI method allows for more control and better team working. Again, there is lots of valuable information on this within the SAP on-line help for Web Dynpro Java and also here on SDN.

Thank you Gareth!

Really It's difficult to find clear information on service/help and sdn.

Now it's clear.

Could I ask you one more question? It's all the morning I'm trying to find this information

Is there any Development Roadmap for the WebDynpro? I mean, I heard at SAP TechED that in future we can generate WebDynpro for ABAP, for Mobile devices and for any UI technology we like. But where are the plans?

Thanks in advance,

Hi,

Besides... is it possible to define your own Widgets?

Hi,

I'm pretty sure that you DON'T need an Enterprise Portal for Web Dynpro. Similar to BSP's, when you create a Web Dynpro application a URL is generated that points to the access point of that application. I'd say that if you are working with ABAP WD then you just need the full ABAP Netweaver stack - create your application via SE80 and then test it there, you will just get a browser window opening with the applicaton running; if working with Java WD then you need the Java Netweaver stack - create your applications in NDS and test from there, again you will just get a browser window with your app runnning.

Web Dynpro applications will just run in a browser as a standalone application but obviously can be incorporated into an enterprise portal if desired.

For more info, I'd suggest you look at the on-line SAP help for Web Dynpro which has lots of useful information on getting started and also look at the tutorials and blogs available here on SDN for both ABAP and Java WD.
