Webdynpro for ABAP vs WD for Java

How different is WD for ABAP from WD for Java?
I have a good knowledge of WD for Java and I know ABAP. But how good and efficient is WD for ABAP? Would it be better to use WD for ABAP or WD for Java for SAP based portal development?
Thanks in advance,
Reena

1. We can embedd the Web Dynpro for ABAP applications in SAP screens in ABAP environment. I don't think it is possible using java web dynpro.

Yes, you probably can, since the application can be fired simply by a URL, there is not reason that you couldn't have an HTML control in your dynpro and point to this URL.
To answer the original question, the development model for each is pretty much the same, just two different flavors. I think that some things make WDA better, one being that it is totally integrated into the ABAP development workbench and the Transport/change control system. On the WDJ side, you development locally and "deploy" your changes using the DTR and CBS. I'm not exactly comfortable with this quite yet, which is why I like WDA better..
Another thing is that we have some built in stuff with WDA, like automatic search help functionality, ALV Grid, and Select-option functionality. I do believe that SAP is working on some of these for WDJ.

Webdynpro for ABAP - Popup apearing for userid and pwd

Hi Experts,
We have implemented ESS and gone live. Now we have created one custom application in webdynpro for ABAP and attached with portal.
Initially there was a problem, the application was not getting executed because of system configuration, then I have configured the host name, port number correctly. Then the iView is getting loaded in the portal.
The problem is, when I am trying to access the iView, the popup apearing for the user id and password. This is happening only the webdynpro abap application, this is not happening for all sap standard iViews.
Could anyone help me with this issue?
Thanks
Jay

Hi Jayanthi,
as you had mentioned this is not happening for sap standard iViews(do you mean simple transaction iViews for which you have used a system alias, which was the same you had used for ABAP web dynpro iview)?
Of courese ESS iViews works with their own JCOs which is no way helpful or connected with wd ABAP.
So I believe if your SAP id and Portal id are different(or if they are same but SAP Logon ticket is not configured properly) then only it woudl ask for the authentication again- for Wd ABAP to work fine, only the connector property and WAS to tbe configured in the system object(aka system alias) used for ABAP iview. Now once you enter the login credentials, it is working fine right, then could you please test the user mapping under the user you are logged in, select the alias that you had used while creating the abap wd iView and provide userid/password here, then run the wd ABAP application, it definitely would work.
N.B: if you had provided the credentials once, then it woud be stored in the browser cache, so if you perform the user mapping in user admin, log off from portal, close all your browser windows, then clear cache,(cookies etc). then login to portal, run the wdABAP application, I am sure this would work(it worked for me!!!).
Thanks,
Jakes.

You are on right track thinking about enhancement framework.
My approach is would be in the following order.

Shortcut keys or Hotkeys for ABAP UI Elements for Navigation

Can we create shortcut keys or hotkeys for ABAP UI elements on an ABAP screen where the user can directly navigate to a particular UI element?
E.g.: Screen containing 5 tabs where the user can directly navigate to a specific tab.

Use Variant for abap in Sapgui for Java 7.00r2 (Mac)

Hi,
When i want to use a, already existing, Variant for a program i get the error message 'Choose a valid entry'.
This also happens whith a newly stored variant.
The Mac version also has problems with the enter key in SE38.
Seems to me the are new bugs in revision 2.

Hello,
both bugs are fixed in rev 2.1, which I made available just few minutes ago. see ANN: SAP GUI for Java 7.00 rev 2.1 available for download

WebDynpro for ABAP F4-help for KAGRU like PERFORM f4_groups in KSB1

Hello,
I must realize a search-help in a WebDynpro-Component which looks like the F4-help in the transaction KSB1 for field KAGRU.
In the report RKAEP000 it looks like this.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR koagr.
PERFORM f4_groups USING    'KSTAR'
                             gs_tka01-ktopl
                    CHANGING koagr.
But in WebDynpro the Function   'K_GROUP_SELECT' wil generate a short dump.
Has anybody an idea, how to make this in WebDynpro?
Greetings

How are you trying to use the search help? You can set up value help in the component itself. Go to the component controller context of your web dynpro component. Select the context node attribute for which you would like to have value help. Now go down to the properties. Next to "Input Help Mode" select "Automatic". If your node attributes were brought in from a table (SAP or custom), then if there is an existing search help it will automatically be brought up now next to "Determined Input Help". Save your changes and activate.
If a search help is not brought in when you change the input help mode to automatic, then you can still create your own method to provide the search help. In this case you will need to create your method in the controller of the view where the user will be entering a value for the field. The method type should be "Method". Make sure to call your search help method within the method WDDOINIT of the view. In the search help method you will need to navigate to your mode, select the values for the field, and then set the attribute value set using those values. You will have to look into K_GROUP_SELECT to see where it is getting the values for KAGRU. I don't think you can call K_GROUP_SELECT directly because it creates a pop-up.
A third option is to use an OVS (object value selector) component. Please see this document for help with OVS:

Is DD/MM/YYYY supported in webdynpro for abap application

Hi All,
We are using 2 different time statements one developed in webdynpro for java and other in webdynpro for abap.date format in java is DD/MM/YYYY but in webdynpro for abap is DD.MM.YYYY.
is DD/MM/YYYY supported in webdynpro for ABAP application or even if user enters DD.MM.YYYY can we convert that to DD/MM/YYYY so that we will maintain uniformity in both the applications
Thanks

How can we benefit from WebDynpro for ABAP over Normal ABAP

Dear Guru's,
Please guide me what are +Ves of WebDynpro over Normal ABAP. Once all Applications are developed how can we organize them. For Example In SD module there is sequence of Tcodes to be executed this is true for all modules . Is there any concept involved in this new technology.
For What purpose we can suggest someone to implement in an Organization.
Many Thanks in Advance.
Regards
Ram

Hi Ram,
Here Are some comparisions I made w.r.t Webdynpro for ABAP (also some benifits over Java):
1     "Pros:it will be easier to move your development project through the system landscape if both the UI and business logic are in the same development environment.(Update: This is is less of a concern now that CTS+ lets you bundle your WD Java UI developement with ABAP development objects into a single transport, with SPS13. )
2     tons of custom ABAP business logic is easier to access via WD for ABAP
3     WD for ABAP has a code wizard, so easy to build
4     SAP List Viewer and ALV handled better
5      The biggest thing is the NWDI. Most of the SAP customer have ABAP stack, but not everyone has the Java stack. To develop WD Java you need to set up the NWDI envrionment, like SLD, CMS, CBS, DTR, etc. which is a huge effort if you don't have them in place. While for WD ABAP, the environemnt is normally there as given for most of customers if they have the right version.
6     If your business is in SAP system, I would prefer WD ABAP. There are many WD components available in WD ABAP like select-option, Alv table, F4-help which are not available in WD Java. Beside in WD ABAP you can deal the context node in form of internal table which is much more performant than dealing with the contextelement which is the case for WD Java.

How to create a proxy object for MOSS integration via WebDynpro For ABAP

Hello all,
I have a question about the creation of an ABAP proxy class in SE80.
When i follow this link:
[https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/6066fbe8-edc4-2910-9584-a9601649747d&overridelayout=true]
i see on page 7 that there is: a tab under create called Enterprise Service/ Web Service with under this tab a tab called proxy object.
When i do this in my SE80 i only see Enterprise Service and not proxy object.
Screenshot
[http://picasaweb.google.be/panneels.robin/SAPScreens#5377623235095894546]
Is there a extra configuration or add-on needed to do this action? Or is there a work-arround for this?
Because we need this for abap web dynpro for communication with MOSS.
Thanks in advance for all your help.
With kind regards,
Robin Panneels

Hi James,
If you like to use SAP web dispatcher as a solution for load balancing portal application, you no need to create system object under systems..
You have to install web dispatcher as separate instance where you need to configure portal apps into it..
Configure web dispatcher like to hit the admin port, use http://<webdisp-server>:<adminport>/sap/admin
For normal portal access, use http://<friendly URL>/irj/portal
The good news is that the webdispatcher knows that the portal supports SSL
Another advantage of this config, is the webdisp, will just replace the apache redirect server. Users will access mycompany.com, without any port number, since we are redirecting 80 to the backend j2ee. Also, https should work like in the normal world.
Profile will be like below...
SAPSYSTEMNAME = WEB
SAPSYSTEM = 00
INSTANCE_NAME = W00
DIR_CT_RUN = $(DIR_EXE_ROOT)/run
DIR_EXECUTABLE = $(DIR_CT_RUN)
Accesssability of Message Server
Message Server Parameters ##########
NOTE: The "ms/http_port" must match the profile on the Central Instance
rdisp/mshost = <FQDN of portal CI Host>
ms/http_port = <Ms port of portal>
SAP Web Dispatcher Ports
#icm/server_port_0 = PROT=HTTP,PORT=81$$
icm/server_port_0 = PROT=HTTP,PORT=80, TIMEOUT=3600, EXTBIND=1 (some OS will not allow to bind ports <1024)

ESS framework in web dynpro for ABAP?

Recently, I need to start an ESS project using web dynpro for ABAP. Unlike web dynpro for java, we have ESS framework in every track, like pcui/xx DCs and ess/per DCs in the track. And as there are existed projects in the DCs like ESS/JP/ADDRESS, we can just follow suit.
My question is: are there ESS frameworks in web dynpro for ABAP? Or existed ESS projects based on web dynpro for abap?
Thanks for your help!

Hi,
As far as i know, it would need really a huge amount of effort to develop ess on Webdynpro for ABAP. As you know that it is not a part of SAP standard delivery, you really have to start it from the scratch.
It would be a custom developed application.

Modelling Info Required for ABAP Work bench

Dear All,
   We need your help in the below issue. Please try to provide your valuable inputs for the same.
   We are trying to develop a solution in the R/3 system which tries to compare different table/fields and checks the consistency of the data in these tables.
E.G: Say we have 2 tables like BUT020 and ADRC, now we would need a modelling tool which sort of maps the primary keys of these tables in the front end and checks whether the data in this table is correct.
    So we would need to write some generic code at the back end which picks these tables/field details at run time and checks the data for inconsistencies. Now at the back end we are comfortable in writing this Generic code in ABAP.
   But we need help in the front end where we can have a modelling tool which say would have a pre-defined set of tables and which would allow us to map these fields in the UI and pass the data to the back end.
    Do you know which modelling tool or a UI which we could use for this purpose. We tried checking with Visual Composer for the UI, but I heard this integrates only with the ESA Repository and we should BO's modelled for the same. So this option was not feasible.
    Please let us know in case you know any tool which can use in the front end to map the tables.
Any suggestion will be highly rewarded.
Warm Regards, Vinay

Hello Sandeep
The reason why it's no longer available is because it's not recommended to install Dual Stack.
The recommendation is to install seperate SAP systems (one SID for ABAP, another SID for Java, a database for each of them).
There are several reasons for that recommendation, refreshing procedure, system copy procedure, setting database parameters seperately for each and so on.
So you would have something like AA1 + Database and AA2 + Database and you connect them using the post configuration steps (template runs etc).
Most or all of the future SAP products will be focused on one engine (either fully ABAP or fully Java).
Kind regards
Tom

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.
