WebDynpro with ABAP or JAVA?

Hi all,
I am a veteran in ABAP. I wish to learn web dynpro. I never worked on JAVA. Can anybody advice me which programming language i should use to learn WebDynpro development. Also let me know which companies have webdynpro projects in India?
Thanks in advance..

Hi Buddy,
         Welcome to intresting world of Web Dynpro.
         As veteran ABAPer you should go for WebDynproABAP .
         Now why ?
Point 1:
In my view WebDynpro ABAP and Wd Java are not same.
Basically WebDynpro ABAP and Java are two different webDynpro provided by NetWeaver Stack.
Basic conceptual base of WD ABAP and WD Java is same.I mean to say concepts like Context binding , node , elements , Layout both support are same.
But when you provide background functionality to your Web Screen then Java or ABAP come in to picture.Just take case , you want do some thing on click of some button then
1) in case of java may you will call some ejb or you will may write some java code on click.
2) but in case of WD ABAP you have to do same thing with ABAP classes . You will call some call or some method of some system defined class.
Ulimately point I want make
1) WD ABAP and WD java 's Base is same but you code in completely different way.
2) Purpose for which SAP came with two different WDynpro is different. Java can be used for developing quite sophistcated Web services.
Point 2:
another help for you .Just go thr' following thread
How much of oops ABAP is required for ABAP Webdynpro .
Point 3:
You can start with tutorials and all

WebDynpro for ABAP Vs Java

Hi all,
I have recently started learning Web Dynpro for ABAP.
I have worked in WebDynpro for Java.
1)I wanted to understand pros and cons of WebDynpro for ABAP and Java.
2)What are the functionality that are available in Web Dynpro for Java but not in Web Dynpro for ABAP.
3)What should be preferred when considering performance issues - WD for ABAP of Java?
Any Web Log or Link in this context will be helpful.
Thanks a lot,
Rashmi

Hi,
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
see the links below, Understand them and start developing.

Webdynpro with abap

Hi All,
How to pass local parameters between views in webdynpro abap ?.....plz help me..
Edited by: charan143 on Nov 11, 2011 5:53 AM

In Componenet controller, attributes tab declare a variable.
Assign this varible the value from view A. Fetch this variable from component controller in View B .
Use the below code for assignment:
Let gv_x be the variable declared in attribute tab of component controller
View A (Method):
DATA lo_componentcontroller TYPE REF TO ig_componentcontroller .
       lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).
       lo_componentcontroller->gv_x = 'X'.
View B:
DATA: lo_componentcontroller TYPE REF TO ig_componentcontroller,
             Y    TYPE string.
       lo_componentcontroller =   wd_this->get_componentcontroller_ctr( ).
       Y =   lo_componentcontroller->gv_x .

IDM7.1- Synchronization with ABAP and JAVA

hi all
we are planning to Integrate EP(datasource: LDAP) and CUA/ABAP system with IDM7.1.
Can somebody tell me How IDM takes care of CUA syncrhonization with LDAP and EP. Synchronization is obsolete or its done by IDM internally.
Please suggest us.
regards

Hi Jai,
1) Connection establishment between LDAP, EP & ABAP.
2) We define a Synchronization Job in IDM to sycn data between all the above
3) When there is a change in LDAP or ABAP, Event Agents (out-of-box idm) detects the change and runs the synchronization job.
How to define the synchronizaiton job is depends on the requirement.
hope the above helps you.

Possibilities Web Dynpro for ABAP versus JAVA

Hello,
I would like to know whether WebDynpro for ABAP and Java have the same options, abilities and possibilities. e'm I able to produce the same results with WebDynpro for ABAP as Java. I would like to standardize on just one of the two and be sure that it will to limit me later.
Thanks in advance.

Hi Maurice,
If you make have to make a choice you have to consider the followings:
- Which release do you have? Java version is available since 6.30/6.40, the ABAP only as of 7.00.
- Performance. If you have your WD4ABAP and backend (eg ERP) in the same system you gain a lot of performance
- Other small difference, that Java version has a much nicer graphical editor, which I miss from the ABAP version
These are, which came to my mind.
Best regards,
Peter

ADS in ABAP and JAVA on different servers

Dear community,
I need to run ADS with ABAP and JAVA on different servers but after read and apply every step on The ADS Configuration Guide, still getting doubts and problems. Those steps work succesfully on a server with ABAP+JAVA on same server. Those are the problems:
When I perform the report test FP_TEST_00 i get this error:
ADS: com.adobe.ProcessingException: Problem accessing d(200101)
I haven't found a a detailed procedure to set on ABAP and JAVA on different servers...
Do you know any procedure to set this scenario??
As a result, I don't know which role i must assign to adsuser on Java UME because i did not found any SAP_ADSCALLER role as i have ridden on some forums or blogs...
I try to set ADS on ABAP+JAVA on different servers by this official guides:
The ADS Configuration Guide:

HI again,
ADS_AGENT now has sap_all but still same problem:
Creating or Changing the Destination Service, On Visual Administrator/Destinations/HTTP/ FP_ICF_DATA_<SID>
When I set the URL http://<hostname>:<HTTP_port> i am getting error Received HTTP response 502
- If I paste the http://<hostname>:<HTTP_port> +
- Enter the appropriate client number of the system, where the service user ADS_AGENT exists into the client field. Keep the other fields System ID and Language empty +
- Under Logon Data, choose BASIC in the Authentication field. +
- Enter ADS_AGENT in the Username field and enter the same password as given for this service user in the SAP NetWeaver AS ABAP in the Password field
- Choose Save and Test and Received HTTP response 502 appears.
But if I paste on Explorer http://<hostname>:<HTTP_port>/sap/bc/fp/form/layout/fp_test_00.xdp, request User (ADS_AGENT) +Pwd and work ok, so error only appears by Visual Administrator...
Anybody knows how can resolve this doubt?
Thanks in advance

Run SAPehpi for ABAP + standalone Java

I have run SAPehpi several times for NW04s ABAP+JAVA. Because ABAP and JAVA are on the same server,
the process is very smooth and easy.
Now I try the same thing on a NW04s with ABAP and JAVA on seperated servers.
Could you share your experience on how to coordinate the dual stack with each on different server?
Blogs and links are very helpful.
Thanks a lot!

Why do you need a sequence if they are standalone systems?
I normally in any other scenario apply ABAP and then JAVA so I would proceed in the same way.
Don't forget the backups :-D

How to integrate WebDynpro for ABAP application with SAPEnterprisePortal7.0

Hi WebDynpro for ABAP Experts,
We developed an WebDynpro for ABAP application on R/3, and now we are planning to show this as an iview on SAP Portal EP7.0 (SAP j2EE Engine--Java stack). is it possible to integrate this application with portal?
If so can you proviode me the way how can we achieve this?
ADV Thanks
Regards
Phani

Hi Alex,
Thanks for your response.
I already created the system object R/3 Backend.
Actually some WebDynpro java applications/iViews are currently running on Portal. and the developers developed these in NWDS and deployed the .sca files on the Portal server and we created Webdynpro for java iViews.
but now the requirement is creation of webDynpro for ABAP views.
The developers developed WebDynpro for ABAP on the R/3 system. So what are the parameter values we need to give at teh time of creation of WebDynpro for ABAP iview like the Namespace, Application name etc which are mandatory values and how the Portal server detects the application, this means no need to deploy the application on the Portal server?
Shall we need to maintain any JCo Destinations or not?
Pl share your ideas.
ADV Thanks
Regards
Phani

IS Webdynpro for ABAP/JAVA is same?

Hi Friends,
I'm a SAP technical consultant. I would like to learn webdynpro for ABAP. Can anyone of you tell me webdynpro for ABAP and webdynpro for JAVA are same? with webdynpro for ABAP Can we acheive what we can do with webdynpro for JAVA?
Thanks in advance,
venkat.

hi,
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the following features that build on the classic dynpro model:
·        Clear separation of business logic and display logic
·        Uniform metamodel for all types of user interfaces
·        Execution on a number of client platforms.
·        Extensive platform independence of interfaces
Web Dynpro is available both in the Java and the ABAP development environment.

Abap vs java in webdynpro

hai..
creating webdynpro in ABAP
creating webdynpro in JAVA
which one of the above is a better option....I mean which has a better future...
Please someone put me out of this confusion.
will be rewarded if helpfull.
Regards,
Jhansi

Hi,
In most areas Web Dynpro Java and ABAP are alike, they are based on the same programming model.
In WDA you have the advantage of the integration into the complete development infrastructure, with transport system etc.
As to functionality, there are some UI elements in WDA that are not yet there in WDJ e.g. FormattedTextView.
Web Dynpro ABAP, on the other hand, does not support mobile devices.
For more information on WDA, Refer these threads..

ABAP Vs JAVA WebDynpro

Hi friends,
I have 6yrs of experience in SAP ABAP/4. I am new to WebDynpro. I have a pretty small question.
Among ABAP WebDynpro and JAVA WebDynpro, which one will have more demand in future wrt market requirement.
Thanks in advance for the information.
Rgds,
AK

Hi AK,
I have worked on both and following is the difference:
Web Dynpro for ABAP:
Web Dynpro for ABAP or Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web applications in the ABAP environment. It consists of a runtime environment and a graphical development environment with special Web Dynpro tools that are integrated in the ABAP Workbench (SE80).
The use of declarative and graphical tools significantly reduces the implementation effort
1) Web Dynpro supports a structured design process
2) Strict separation between layout and business data
3) Reuse and better maintainability by using components
4) Automatic operation of the Web Dynpro application using the keyboard
5) User interface accessibility is supported
6) Full integration in the reliable ABAP development environment
for more see this:
http://help.sap.com/saphelp_nw2004s/helpdata/en/77/3545415ea6f523e10000000a155106/frameset.htm
Web Dynpro for Java:
Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
Web Dynpro helps you with the development of Web applications by:
1) Ensuring platform-independence with the meta model approach
2) Minimizing the implementation effort through declarative programming
3) Supporting a structured design process by applying the model view controller paradigm
4) Providing reuse and better maintainability by using components
5) Providing graphical support with tools in the Web Dynpro perspective
6) Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/content.htm
The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions
Hopw this will help you.

Comparison between WebDynpro for ABAP vs. WebDynpro for Java ??

Hi,
Can someone tell me when should we go for WebDynpro for ABAP and when WebDynpro for Java. Is there any link where SAP recommends the one for the other.
Thanks in advance
Regards
Mukesh

Hi Mukesh,
Both are having its own strengths!! )
I think it all depends on your project requirement and the availabel resources.
If the developer is good in OOPs ABAP then he must go for Web Dynpro ABAP. But if anyone is good in JAVA then that person should go for Web Dynpro JAVA.
*In Short almost all Features supported in webdynpro ABAP are also Possible in webdynpro Java.
1] Webdynpro Java
Supports,
webservice
RFC Models
Accessing Portal information in Java
Easy sending E-mail
Strictly follows MVC architecture which seperate Business logic and Process flow.
Webdynpro Java is webbased programming model to develop SAP Applications.
Easy to learn
Easy to integrate in Enter prise portals.
Dynanamic Programming
*Easy access to R/3 Via RFC technology (Models)
2] Web Dynpro ABAP
As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
Hope this helps and solve your Problem
Cheers,
Darshna.
