Abap WebDynpro or Java WebDynpro

Hi All!
Which differenced are existing between Abap WebDynpro
and Java WebDynpro. Is it e.g. possible whether
one IView which has been created through Abap
technology combinable or adaptable with an Ivew which has been
created through Java Technology? Or is it a decision in principle
(policy decision)at the bgeinning of a project which one you take ?

Displaying both ABAP webdynpro and Java Webdynpro tasks in the UWL

Hi,
We have two an issue when trying to get the UWL to process two different types of workflow tasks : ABAP webdynpro and Java webdynpro.
Examples of these tasks are:
TS12300097 u2013 LeaveRequestApprover u2013 Java Webdynpro
TS17900100 - ASR_PROCESS_EXECUTE u2013 ABAP webdynpro
We have two backend systems configured
SAP_ECC_Financials u2013 This has the WAS host pointing to the java stack (xxx:50000)
SAP_ECC_Workflow u2013 This has the WAS host pointing to the ABAP stack (xxx.80xx)
In transaction SWFVISU all the tasks which use Java webdynpro have been configured to use the u2018Javau2019system (SAP_ECC_Financials) using the SYSTEM_ALIAS parameter
In the UWL configuration the system SAP_ECC_Workflow has been registered
In addition to this all u2018Javau2019 tasks have had an extra UWl config XML created to ensure that the SYSTEM_ALIAS is set to SAP_ECC_Financials
The system SAP_ECC_Workflow has been re-registered
The UWL cache has been cleared
However when we try to launch the java webdynpro tasks the system is trying to access the ABAP stack (It is still trying to access the Web AS location for the system SAP_ECC_Workflow even though the system alias was specified as SAP_ECC_Financials )
The ABAP webdynpro tasks (in this case a HCM process and form) are launched correctly
If we try the reverse (i.e register the Java system SAP_ECC_Financials and change the SYSTEM_ALIAS parameter for the ABAP webdynpro tasks to system SAP_ECC_Workflow) then the reverse happens. The java tasks can be launched and the ABAP tasks cannot.
Does anyone have a solution to this problem. Surely other people have implemented both ABAP and Java webdynpro workflows?
Any help much appreciated
Andrew

Thanks a lot for all your replies..
The workitem type registration has been done already, but still it doesn't work..
But here is the actual problem...
There is a link 'Execute Workitem' in the inbox of the approver, or the second level manager...
In the leave application, when we click on this link it is taking to the portal as the task is the Webdynpro Java application task. Whereas, when using ABAP webdynpro application task, it is taking to R/3 - which means that the user cannot access this link without R/3 access. The users are given only portal access, they don't have access to backend R/3.
The requirement is that the link has to take the user to portal directly instead of R/3 - i.e it should ask only for the portal id and password.
Since it was working fine with leave application, I changed the task to Java webdynpro task, but I think the Java Webdynpro application is not deployed in the server.
Please can anybody suggest.
Best Regards,
Sushmitha

Adobe Interactive forms - ABAP Webdynpro or JAVA Webdynpro?

Hi,
I am an ABAPER and I got few requirements for Adobe Interactive forms Offline Scenario/Online scenarios & ALV reports.
I have practiced a session ( How Tou2026execute an RFC model with inputs from Interactive Formswith RFC Module ) -JAVA webdynpro where it interacts with SAP via BAPI.
Now my question is I am bent more towards ABAP.. I want to do this in ABAP but unfortunately I haven't found any similar material for ABAP webdynrpo.Could anyone pls suggest me !
FYI.. We are also developing some ALV Webdynpro reports and I am using PURE ABAP which i like it.
So the other reason is we don't want install NWDI and complicate this structure as we don't have ESS/MSS requirment here. Just we need some forms/reports on portal.
Any suggestions and links which can help me here?

Hi Vara,
You can develop Interactive forms using WD ABAP also.
[E Learning- Interactive Forms using WD ABAP|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/media/uuid/c766e918-0b01-0010-99b1-c2b78cd059b3]
WD Java is useful in case, when your ABAP system is less than ECC 6.0. Otherwise you can achieve same functionalities in WD ABAP also.
Hope this will help you.

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.
Cheers,
Darshna.

How to learn webdynpro for java/ABAP

hI Experts,
i am new to webdynpro technology.
and i am having the knowlgedge on Portal contenet development&administration,and having the strong knowledge on Visual composer7.0,7.1 and also trined in ABAP(currently i am not useing it).
now i wants to learn webdynpro for java/abap.
is it right choice i am taking ? i.e moving to Webdynrpo for java/abap.
what are the minimun skills i need to be a good webdynpro developer for java/ABAP. ?
is it requires straong java knowledge since i am not familiar with that too much ?
please give your valuable inputs
Thanks&Regards,
Govindu

SAP uses Webdynpro to build portal content, which later will be configuted as an Iview in the enterprise portal. Webdynpro comes with Java and ABAP flavors. Both have in general the same functionality,the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
If you are good in ABAP go with ABAP Webdynpro, if you are good in JAVA, go with JAVA Webdynpro. But you will get good opportunities in JAVA Webdynpro compare to ABAP Webdynpro.
Thanks,
Chenna.

ESS/MSS in ECC 6.0 are Abap or Java WebDynpro ?

Hi ,
We are on ECC5.0 and have ESS/MSS on Java WebDynpro . For ECC6.0 are ESS/MSS in ECC 6.0 are Abap or Java WebDynpro compoment ?
Any watch out when updrading from ECC5.0 to ECC6.0 ?
Thank you .

in ECC 6.0, ESS/MSS are WebDynpro Java calling ABAP backend function modules. However, be careful, there is a switch that enables SOME ESS services as ABAP WebDynpro (Especially in the Travel management area). Unless you use that switch all services are WebDynpro Java.
when upgrading from ECC5.0 to ECC 6.0 you need to test again all ESS/MSS services. In ECC5.0, services are written as Portal iViews, so customizations you made to ESS in ECC5.0 may be lost.
let me know if you still have questions.

Your opinion on: BSP or Java Webdynpro or ABAP Webdynpro?

Could you please give me your opinion on the business scenario we have here:
We are implementing SRM 4.0 with backend R/3 4.6C, WAS 6.4 and Portal 6.0. SRM has its typical shopping cart applications mainly for procurement and the workflow trail displaying the approval. The client wants us to build a few custom forms on the web frontend of SRM (or may be in Portal). The idea is to store these forms and display when needed with the status info just like a shopping cart.
<b>Now the requirements for these forms are as follows:</b>
1. These forms will have multiple fields which need to have the F4 kind of help. (the F4 options will reside in SRM or R/3)
2. The form should have some kind of a ALV grid (autoexpanding feature) which will allow the user to put in multiple line items so that they could submit more items on one form.
3. Users need to be able to attach a spreadsheet to the form which should not be editable once the form is submitted. The attached spreadsheet should be stored. (We are planning on using Archivelink Filenet for this)
4. Upon submission, a workflow will be kicked off as per the defined Org structure for approval of the form.
5. After submission, the user should be able to go and view the approval status of the form and also print the summary of the values that he entered in the form. (may be a smartform could be provided for this)
We looked at different options to accomplish this task:
<b>BSP:</b>
Creating BSP pages and giving access as links to the user on the webfrontend of SRM. Now, if we go the BSP route, we need to develop in SRM as the R/3 4.6 c does not have BSP development capabilities. If we take this approach, I am not sure if all the above requirements (specially like attaching spreadhseets) will be met with BSP pages.
SAP Webdynpro Java:
It seems that the Webdynpro is easier to use because of the graphical tools available. But the only problem if we go this route is that we will have to find a java guy.
SAP Webdynpro ABAP:
We currently have WAS 6.4. As per the documentation, the ABAP Webdynpro development tool is available from NW04s onwards. So, we are still not sure if we could use it. But, we want to push towards upgrading if necessary. Being an old time ABAPer, developing ABAP Webdynpro seems do-able. (i know it may not be that easy).
Last but not the least, DIALOG Program:
Creating a dialog program in R/3 or SRM seems fairly simple. Then, an iview could be created on the portal for this transaction, though at this point I am not sure how a spreadsheet could be attached and stored within a dialog program.
The creation of the workflow may not be that bad after the original form is designed. The graphical display of the approval trail might be difficult, but we might get away with a report for that. For printing the details of the form, I guess I could develop a smartform and put out a button on the screen to print it out in the display view.
Could you please give me your opinion / best approach for accomplishing this task, keeping in mind the complexities of these new dimension products?
Thanks
Sri

I would say that all four solutions to solving your tasks are technically feasible. Here are some thoughts that I had however:
First ABAP Webdynpro: it is true that ABAP webdynpro is only available with Netweaver04s. 04S is still in ramp-up which means that only a subset of the customer base is allow to implement it. It will not become generally available until later this year (check the service marketplace for current release estimates). That being said, it probably elimintes WDA as a possiblity for your project unless you are will to wait and to upgrade.
However having worked with WDA for a while it is probably the best tool to custom develop what you describe. It has excellent built-in F4 value help. It also has a damn fine ALV grid implementation. The spreadsheet could be just as simple as file upload in binary or your could try your hand at office integration. Finally for the form you could use Adobe Interactive Forms which also has very nice integration into WDA.
Now to Dialog Programming: You could of course use dialog programming. It seems a little bit of a waste to custom build something so large if WDA is in your near future. There are obvious disadvantages (little OO structure, no MVC, etc). You would have ALV grid, office integration and of course F4 help. You could still use Adobe forms if you implement this on the 640 system. However there are integration points with dialog and Adobe Interactive Forms. You could still use printed forms however. If you did the dialog program on the 640 system, you could use the integrated ITS to expose it to the web. The integrated ITS in my experience has quite nice performance although the look and feel remains just like the SAPGui.
The Java Webdynpro route: Well you hit the nail on the head - if you don't have a Java programmer already and you don't have the bandwidth to invest in learning Java, this can be a problem. The Java Webdynpro environment is quite nice. There are some things I like better than ABAP and some things that ABAP is defintely still better at. However when it comes to heavy integration with an ABAP backend - ABAP Webdynpro is still the way to go. Java Webdynpro does have a help feature (OVS), but it isn't "for free" or nearly as nice as the ABAP Webdynpro (perhaps it will get there some day). That is one of the major advantages of WDA - its closeness to the business data brings several framework advantages like F4 and field help. WebDynpro Java in 640 also doesn't have an ALV grid implementation. I am sure that this is something both environments will eventually have, but right now ABAP has the advantage. On the other hand, Webdynpro Java has equal support when it comes to office integration, file upload, and Adobe Forms support. You would have a more difficult time integration SmartForms however.
Finally we come to BSP. Honestly if I were in your position I would probably choose BSP (unless you could wait for the ABAP Webdynpro upgrade). You could build a nice MVC OO application using BSP (stateful or stateless). The BSP product is mature and quite well documented thanks to SDN. You have the BSP Extensions which when used in Design2003 use the Unified Renderer. That means that your output will look nearly identical to the same UI elements in Webdynpro. Also BSP supports portal integration (session management, eventing, and themes).
The downside to BSP is that it isn't a full framework (also one of its advantages). You can insert all your own html and javascript (unlike webdynpro). But this also means that SAP doesn't delivery as many framework services. For instance there is no ALV or Value Help. There is no Office Integration or Adobe Forms integration. There is some farily good Smart Forms integration. Now the upside- many people have already hit these limitations and overcame them. In the weblogs on SDN and in a certain SAP Press book (cough, cough) you will find out of the box solutions for many of these problems. You can find ready to use solutions for Adobe Integration, Office Integration (using Microsoft Office Web Controls), and F4 help. It will mean investing a little more time up front to get this "home grown framework" up and running - but it is perfectly feasible.
There is a learning curve to all these new technologies however. This sounds like an abmious project. I wouldn't want to try and tackle this project in any of these technologies if I was new to them. With Webdynpro or BSP - consider giving yourself time to learn the environment and cut your teeth on some demo apps before jumping into such a huge development.

How to launch Java WebDynpro From ABAP?

I have a requirement to launch a Java WebDynpro from ABAP code. Has anyone done this? If so, does anyone know of documentation/sample code or at least an ABAP class/function group I could look at?
Thanks in advance.

The webdynpro application can be triggered simply by a URL, so this is really easy in ABAP.
All you need to know is the URL for the WDJ application running on your java engine.
report zrich_0001.
data: url type string.
url = 'http:\www.sap.com'.
call method cl_gui_frontend_services=>execute
EXPORTING
DOCUMENT = url.

For ESS which one is better ? (Webdynpro for Java or Webdynpro for ABAP)

Hello ,
For developing Employee Self Service(ESS) which one is preffered Is webdynpro for java and webdynpro for ABAP ? Why ?
What are the differences ?? Please give me clearly.
Thanks
Risha

Hello Olivier ,
Thank you for gvg quick reply.
For dessert which one is preferred : apple pie or chocolate pudding ? - I am not able to decide
Actually I have requirement for developing ESS in Portal. I am new to ESS and heard presently using WDA for ESS.
I did't get reasons why using WDA. basically I am from WD for Java.
If possible give me differences.
Thanks

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.

Issuse with WebDynpro iViews - Java or ABAP

We frequently get calls from users who complain that they can't see a screen in the portal, and it is usually because they have accidentally collapsed an iView.
The problem we have found is that it doesn't seem to work with WebDynpro iViews - Java or ABAP.

Rohit,
You can also hide the tray display on you portal by setting the iView property "Show Tray" to "Yes".

MSS, Webdynpro for Java(EHP4) , Webdynpro for ABAP

Hi Experts,
We have EHP 4.0 with MSS in Java webdynpro iviews and are primarily interested in the ECM portions of MSS.
We wants to stay with EHP 4.0 standard iViews and make minor changes to accommodate their business conditions u2013 without making any enhancements directly on the Java iViews. No setup for Netweaver Developer Studio environment or other tools for Java development.
We have to achieve the following without enhancing the Java iViews directly. Making use of existing standard error messages and RFC calls are some of the solutions suggested by the client.
1.)Display error messages on the Java iViews based on some employee infotype consistency checks
2.)Disable employees for input when they fail consistency checks
3.) For employees with multiple performance ratings, display a Java-less popup which will have a table of information as a u2018display onlyu2019 window.
Can anyone help me on any of the above given points.
Thanks,Shilpa.

Hi,
I wouldn't call myself an expert with WDJ but we've made some changes to the XSS WebDynpro's without modifying the SAP delivered WebDynpro's. This was mostly done by creating a new page layout and adding javascript to it. By placing the XSS WebDynpro's in the new pages we could manipulate some parts of the functionality.
However, now that we have NWDI in place we prefer the route where we modify the application instead of workiarounds.

ADS configuration error - PDF form not displaying for Java WebDynpro

Hi Experts,
Sub : Problem with configuring Adobe Document Services
We have installed .. NW2004s SP12 on HP-UX OS.
As of now all the services are working fine, recently started configuring "Adobe Document Services", followed all the instructions given in the guide.
Environment :
=============
- Configuring ADS Webservice for "BASIC" Authentication, not for SSL
- Poratl (AS JAVA) and BI (AS ABAP) are running in different systems.
- Portal using UME as the data storage.
- OS is HP-UX
Configuration Check for Interactive Forms in Web Dynpro for Java
=================================================================
1. Checking the User and Password ---
http://<server>:<port>/AdobeDocumentServices/Config -- the system displays the version number of the Adobe document services in the response area.
2. Configured Webservice for Basic Authentication -- success
In the process of testing this configuration -- i've developed a Java Webdynpro interactive form and deployed into my DEV server (NW2004s Sp12).
Unfortunately, form is displaying in my sneak preview version (Nw2004s SP9), getting error when deployed into Dev server - NW2004s SP12 on HP-UX.
We haven't installed ADS separately, making use of ADS comes with the default installation.
Error :

I found that the following directory is empty in DEV server ... /usr/sap/EPL/JC03/j2ee/os_libs/adssap/XMLFormService, but not in sneak preview version.
Please do let me know to solve the problem.
Thanks

Thanks for quick response.
Installed Reader in my PC, i can view the deployed interactive form thru sneak preview, but getting the following error when running the same application thru my development server.
java.net.SocketTimeoutException: Reatimed out
