Webdynpro Java and Webdynpro ABAP

hi all,
Im working in webdynpro java. Im confused about WD java and WD ABAP. which one we should select for what? And now a days people are telling that SAP is coming up all business packages in WD ABAP. Is it true? Which one is better either WD Java or ABAP?
Thanks,
J.Smitha.

Smitha,
It's tough question to answer. Which one to choose either Web Dynpro java or Web Dynpro ABAP , it depends on which technology you are comfortable. In relation to the business packages SAP already provided allmost all of them in java and in the future all the Business packages also available in ABAP. It's all how you want to develop the application. In sap portal world some applciation which we can develop with ABAP Web Dynpro and some applications with JAVA Web Webdynpro as SAP Web AS available as dual stack.
If someone already has a strong ABAP background and has WD for ABAP available they should probably use that. If they are a J2EE developer they should probably use WD for Java but it is likely they will also then need some ABAP support for the backend systems.
I think more customers may be asking for WD for Java projects simply because it has been around longer and is more widely available to customers where as some cutomers prefer to develop their application using ABAP Web Dynpro because of SAP propritary. But ultimately it's again all our interest and customer.
Thanks

Start both Webdynpro JAVA and WebDynpro ABAP from UWL

Hi all:
We are facing a situation. We need to start both JAVA dynpro and ABAP dynpro applicaiton from uwl. The JAVA dynpro application is the ESS absense request. And we also developed other workflow which use ABAP dynpro as work item . The problem is when we regist our ECC system to UWL, the system can only provide WAS java information or WAS ABAP. So there are alway one type of our work items can't start correctlly. How can I modify the UWL configuration to meet our requirement?
Anyone knows please notify, thank you very much!
Wayne

Hi,
when you try to register backend system , you will choose system alias which was already existing in the portal which has WAS hostname and port.
that is sufficient. Based on visualzation parameters , you can launch webdynpro abap/java tasks.

Webdynpro java and oracle DB connection..

Hi,
I have a good knowledge of WD (web dynpro java) projects having ECC as backend as i have done lot of projects where ECC is backend and WD JAVA is front end.
but in my new project i have wd java as front end but my backend is oracle DB. I want to know how to create/setup connection betwen webdynpro java and oracle DB, how to proceed on this ? wat all settings I have to do in VA (visual admin) and all.
please let me know how to proceed on this. Any document/tutorial on this will be very helpful..

Hi Rahul,
Create a DataSource to the oracle db in Visual Admin, give the datasource an alias name and connect to the db from WebDynpro by calling the alias name.
These document might be useful:

Comparision matrix of Webdynpro Java and Adobe Interactive form

Hi Experts,
In our project we have to choose the GUI between Webdynpro Java and Adobe Interactive forms. Can anyone help me out with strong comparision parameter's in order to select the right technology.
Thank you in advance.

Hi ,
Depends on your project requirement : if you project is simple and want to use less UI controls then use Adobe Interactive Forms (AIF).
But In your project needs large number of UI controls and to show huge amount of data then best option is Web Dynpro Java.
Web Dynpro provides wide varieties of UI controls for designing your web application . Adobe Interactive Forms have limited controls .
Web Dynpro take care of your Client side eventing which is not possible in AIF . AIF Developers needs to know Adobe scripting too.
If your Client data is huge AIF take so much of time to render your content and also this depends on your reader version installed on the end user too . Web Dynpro Java is Client neutral & it won't take much time to render the content.
Use AIF to show/process Business data in any Web application. ideally it is not suited for complete GUI of your project .

Rakesh Kumar

BI Java and BI ABAP -RSPLAN issue

Hi All
We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
Already run the template intaller for BI Java and ABAP integration.
But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
Since this is not correct and it should open BI Java portal instead of ABAP stack page.
Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
There the default Url is BEx Portal Server and the url is
http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
Can anybody let me know why this is going to ABAP server instead it should go to Java.
Regards
Ajay

Webdynpro JAVA VS Webdynpro Abap

Hi all,
which one is the best platform of webdynpro (JAVA OR ABAP)
Regards,
Antony.A

SAP announced a number of years ago that Web Dynpro Java had reached maturity and would be developed no further, only maintenance updates and fixes would be rolled out. WD ABAP however is still be enhanced.
Ultimately, if you want to consider non-ABAP web development you should be looking at SAPUI5/OpenUI5.
Having said that, WD Java is still a powerful tool and I enjoy working with it - as Shai Lapidot has mentioned with the link above, there is life in the old dog yet...

Webdynpro Java and ESS/MSS

Hello,
It has been a rumour for a long time and now it seems that SAP will convert all ESS/MSS services into Webdynpro ABAP....so i want to know what's the plan for Webdynpro Java ...? what areas will it be used...? and what are the options for Webdynpro Java Developers....? ...one thing for sure is to learn Webdynpro ABAP...
Regards,
Anil

As far as I know, SAP has changed travel management and HR administraor from WDJ to WDA as of EhP1.
Do you have any ideas about any other BP?
Actually, I wonder SAP has been developed any new BP based on WDJ after EhP is introduced.

Hi Santosh,
This is pretty basic stuff in the world of Web Dynpro Java - I'd suggest you search SCN, read content on help.sap.com and then come back here with more specific questions.

Hello Nag,
there are two possibilities to use your ejb in WD4J:
1. Via JNDI Lookup
try {
        InitialContext ctx = new InitialContext();
        <YourEJBInterface Class> service = (<YourEJBInterface Class>) ctx.lookup(<JNDI-Name>);
} catch (NamingException e) {

How to configure the connection between AS JAVA and AS ABAP

Hello,
I have installed a SAP Netweaver 7.3 AS JAVA and I would like to connect this JAVA Instance with 3 ABAP Systems (ECC 6.0) .
On help.sap.com I have found the following instructions: http://help.sap.com/saphelp_nwpi71/helpdata/en/3b/0c4b428f96ab53e10000000a1550b0/content.htm
Could you please advise, if the above configuration steps are OK?
Or could you please help me with the exact procedure?
Thank you in advance!
Noemi

Noemi,
I'm not sure how exactly you want to use ABAP and Java so it is hard to answer your question.
The link that you posted describes the steps to configure ABAP as a Security Assertion Markup Language (SAML) service provider. As a service provider, the AS ABAP enables you to off-load the authentication of users onto an identity provider. The identity provider enables you to federate identities across domains for Single Sign-On (SSO).
Check the following wiki page for a good overview of all the ways that you could connect to ABAP

One JAVA and multiple ABAP Instances

Hello All,
Till now i have done configurations for Billerdirect on one Java instance and one ABAP instance.
Now my situation in production we have multiple ABAP (1 CI + 4 Dialog) and only one production Java instance.
So in XCM configuration using method group_connect i have created XCM configuration this is working fine.
so here is our problem after doing this .
For self user Registration we have created JCO_RFC_Server in XCM this configuration is working only in one situation.
Since JCO_RFC_SERVER can be created only for one instance when ever self user registration goes to other instance it fails , which is happening frequently
Can anyone please help me understand in creating XCM configuration for multiple ABAP instances so that i can create multiple JCo_RFC servers.
Over View:
From one Java instance i want to establish multiple connection to ABAP (CI + DI) so that i can create one JCO_RFC server for each connection.
When i want to access system i will access using XCM connection name at the end.
eg some thing like this.
http://myserver:53000/bd/public/frameset_top_html.jsp?SYS=MYSYS1
http://myserver:53000/bd/public/frameset_top_html.jsp?SYS=MYSYS2
Please help in moving forward.
Thanks in advance.
Regards,
Vardhan.
