Web Dynpro ABAP - Java stack required?

Hey everyone,
We are currently planning an upgrade to ECC 6.0 and Netweaver 2004s. A source of debate during this planning has been whether or not to install the Java stack in our upgraded system.
I'm an ABAP developer, so I'm really looking forward to using Web Dynpro ABAP. Does anyone know if the Java stack is required to effectively use Web Dynpro ABAP? It seems like the two should be independent...but I just want to be sure.
Thanks in advance!!

No, you do not need the java stack to run WDA applications. It runs purely on the ABAP stack. You can develop your WDA app in SE80 and run it. It will run in a browser from the ABAP stack. If you have a portal, then you know that this runs on the java stack. Also, your portal is probably not running on the same box as your backend ERP system. If you running a portal, I would suggest installing both the java stack as well as the ABAP stack for you portal to run on. Then you will be able to use WDA to create applications to run in your portal.
So to sum up, the portal runs on the java side, if you have both stacks running under your portal you can development WDA and WDJ applications, which both can run on that same engine. To answer you question, you DON'T need the java stack to develop and run your WDA application, but if you want it to run in a portal, then you need a java stack to run the portal on top of. This can be a completly separate box and a standalone java stack. Did I confuse you even more?

Web Dynpro without Java stack?

Thanks

Hi Aleksandra,
Yes it is posible to develop and run Web Dynpro applications without Java Stack.
For Web Dynpro for ABAP :- Java stack not required, you can do with SAP System T-Code - SE80 if Web Dynpro Component available in your sap system.
For Web Dynpro for Java :- You must require Java Stack.
Hope this will helps you.

Theming Options for Web Dynpro ABAP/Java - Custom CSS

What options are available for creating a custom CSS for WDA? My project is going towards SAPUI5, and they want to apply the same look and feeavl to their Web Dynpro applications.
I know the Theme Designer is an option - but this customer is running on NW 7.3. Obviously to get the WD CSS to look similar UI5, it will require changing all of the WD selectors.
Finally, we have a 7.4 Sandbox. If I build the theme there, is it backwards compatible to their 7.3 landscape?

UI Theme Designer is the only supported way and it is available for NW 7.3 as well, assuming you are up to date on Support Packages. As long as you create a theme with UI Theme Designer the theme will work in any system that supports the same, there might be small functional and visual differences though depending on the SP levels of the source and target systems. SAP recommendation is to always use the latest version available to create (and consume) themes. You could start by using the Cloud version of UI Theme Designer, export and import into your own system. That said your NW 7.3 system needs to support UI Theme Designer to be able to use custom themes created by it.

Notification Service in Web Dynpro for Java?

Hello Experts,
I'm new on the topic "web dynpro for java" and have a question about a real-time-notification of web dynpro clients.
In web dynpro for abap ther is apparently a new solution called "Notification Service" (since NW 7.0 Ehp2).
Details: http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/f0802995-3433-2c10-2787-d7db51352891&overridelayout=true
But I found no hints how to solve the problem of a real-time notification in web dynpro for java.
Requirements for short: The server can trigger a refresh in one or more web dynpro clients.
Requirements a liitle more extended:
1. A web dynpro is running in a browser and shows data it gets from a DataBase table1
2. Now a function module1 is started by an event and changes the data in table1 on the server side, the web dynpro does not know about this event or the changes made by external components.
3. These changed data should be visible immediately in the running web dynpro after the event occurd --> trigger a refresh of the web dynpro from the function module1?
All I actually know is that: The web dynpro can update its context with the new data from table1 after a refresh of the gui (wddomodifiyview). Using a timed trigger I can get new data after x seconds (same way --> context update and gui refresh). Is there another way to refresh the web dynpro (that noticed requirements of #3) ?
Regards,
Anja Hormann

I recommend that you create another Web Dynpro application with this Timer to execute an RFC. This application would be in a Web Dynpro iView hidden from your SAP EP and shoot an event that would be captured by another application.
However I would take great care with this type of application.
And to answer your question at the moment, to my knowledge, there is no solution for this kind of integration between the ABAP and JAVA.

Angelo

Event handling for closing a browser window on portal in web dynpro abap

Hi,
I am new to portal as well as web dynpro. Is it possible to handle portal events in web dynpro abap? My requirement is whenever a browser window is closed on portal, if any new system messge has been added I want to display them in a pop-up. I checked examples from the package 'SWDP_TEST' but they trigger events in web dynpro and pass them to portal. I want to subscribe to the close event of portal and handle it in my web dynpro abap application. How can I achieve this? Please suggest.
Thanks and regards,

Hi,
I dont think that you can code to close IE browser window as you cannot access MS IE APIs in WD ABAP. I looked into closing IE browser and got http://p2p.wrox.com/general-net/16588-handling-ie-close-event.html . reading this, it seems the coding can be done in C#(asp) etc.
also refer Closing of IE window
I hope this is useful for you.

Want documents for   Web Dynpro ABAP

Hi All ,
Can anyone please send me the Docs or link for   Web Dynpro ABAP .
Thanks in advance
Rahul

Hi Rahul,
   Welcome to the interesting world of Web Dynpro ABAP !
For Web dynpro ABAP you will require SAP ECC 6.0 onwards and WAS 7.0
is a must. It has very good future propspects as this is best UI technology.
In web dynpro ABAP we follow MVC(Model View Controller) architecture.
In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.
e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
To start with Web dynpro ABAP you can try following tutorial:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e036712
You can start with tutorials and all. There are around six tutorials in SDN library.

/people/marilyn.pratt/blog/2005/12/20/web-dynpro-for-abap
Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .
Wait not just that SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )
See packages like SWDP_DEMO , SALV_WD_DEMO
there are many more .

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
 I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
 procedure"
 Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
 signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

How can I call a java object from Web dynpro ABAP application?

I made Web dynpro ABAP application and posted it to SAP EP.
For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
Is there anybody who experienced this kind of java interface issue?
I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,
Raymond, ABAP Consultant

if you have jco configured, then you can make calls to java api from ABAP .

Web Dynpro Java to Web Dynpro ABAP

Hi all,
I am a web dynpro java developer with more than 3 years of portal development experience.
I am now put into a project with web dynpro ABAP(ESS/MSS customization).
Would like to know whether I should start concentrating more on ABAP or SAP HR?
I dont have any ABAP programming exp except that attended a training few years back.
And on SAP HR,dont have much exp except that have some knowledge on ESS customization in dynpro java.
Please let me know where I should start to get myself refreshed before starting my work.
Any advice/docs are invited.
Also,please let me know whether there is any NWDI required for ESS/MSS customization in webdynpro ABAP.
Thanks
Meena

Hi Meena,
As you have good experience of Web Dynpro JAVA.
I think you just need to comcentrate on ABAP skills.
You need not concentrate on SAP HR as ur work is technical your functional guys will take care of HR module and will help you.
For starting i would suggest you to just go through the basics of ABAP like Work areas , internal tables etc.
Then start doing some WD ABAP hands on.
My scenario is similar.
I am a portal and WD JAVA person and this is my first WD ABAP assignment.
I followed the above approach.
You will find many concepts similar to WD JAVA as this is just the ABAP flavour of Web Dynpro.
The below link will help you a lot

It always advisable to go to service.sap.com/instguides.
slow and steady wins the race.
good luck.
It's advisable to have quad processor with atleast 8GB ram.
If it's a nw04s then at a shot you can select AS ABAP. JAVA, EP, PI(XI) and proceed.

Created in Web dynpro Java or Web dynpro ABAP

hi all,
I have a web application running. Its UI is created either in web dynpro java or web dynpro ABAP. Is there any way by which we can find out that in which form of UI technology is it created; in web dynrpo java or web dynpro ABAP ?

Hi,
I am really not sure if this is recommended..
Try some negative testing on the application. If the application crashes, the trace of the error occured will tell you what kind of development has been adopted for the Web Dynpro application.
Another hint can be the port number in the Application URL. If it is not 50xxx, and is somewht like 8xxx, it is surely Web Dynpro for ABAP.

Alka.

Web dynpro abap or java ?

Hi All,
Our client wants a web front end for the SAP system and has asked us to search which web dynpro ABAP or Java will be suitale ?
They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?Also is there demend for web dynpro developers in the market ?
Thanks & Regards
Gaurav Jain

>They were of the opinion that web dynpro for ABAP is not that good for web interfaces is it correct ?
What do you mean by Web Interfaces? Web Dynpro ABAP and Java are well suited for created browser-based (or rich client based) business application User Interfaces. If by Web Interfaces you mean Internet facing, highly customizable user interfaces - then no - neither web dynpro abap or java are really well suited for that situation. WDA and WDJ are both designed to create consistent Business Application user interfaces.
Now if you just want to compare WDA and WDJ - that is a very different question. The differences in capabilities are relatively minor. Generally it comes down to which programming language you have more of a skill set in and how close to the underlying data you need to be. Also are you planning to extend existing SAP applications? WDA is primarily used by SAP within the Business Suite (ERP, SRM, PLM, etc) - two exceptions however - WDJ is used in ESS/MSS (although newer portions of that solution are in WDA) and CRM uses BSP/CRMUI. WDJ is used by the middleware components (Portal) and edge or composite applications.

Hardware requirement for Web Dynpro for JAVA

Hi Friends,
I am a starter in Web Dynpro for JAVA and about to develop web dynpro application in JAVA.Can anyone please guide me on the hardware requirement for this application of SAP?
Presently I have ECC 5.0 installed in 1 GB RAM using 160 GB harddisk.
Regards
Ashish.

Hi Ashish,
If you want to install NWDS only then as said 1g.b is sufficient.
But if it's Personal System then you have to install Portal also( WAS).
You will require minimum of 2g.b of RAM and 120g.b of hard disk.

Diff in web dynpro abap and Java

Hi Friends,
   I am new to web dynpro ABAP and Java.
     1) Please give me idea about about these two
      2) In which Scenarios these are helpfull
     3) From which version   onwards these are existing
Thanks for your help.
Thanks,
Asha

Hi Ravi,
The following are basic differences between ABAP and JAVA WD.
1. ABAP WD can be developed in ABAP Workbench thru transaction SE80 whereas Java WD needs SAP NetWeaver Developer Studio.
2. Since ABAP WD is a part of the ABAP Workbench, it has direct access to ABAP dictionary. Hence access is faster.
3. In order to develop on ABAP WD, you will need basic knowledge of ABAP objects, whereas in Java WD, dev is using Java

Web Dynpro JAVA VS. Web Dynpro ABAP

Hi,

Hi,
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

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.

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
