Implementing WebDynpro ABAP in JAVA Portal

Hello
We have a JAVA enterprise Portal and we would like to create an iView of WebDynpro ABAP application.
We have done it in our QA portal by creating a system and in the property editor configuring the "Web AS Host Name" & "Web AS Path".
It works great becuase there is only one ABAP application server.
However, in Productoin we have several ABAP application server and one central instance.
If i create a system using template and choose "SAP system with load balancing" , still In the property editor i see only "Web AS Host Name" .
How can i set in the system's property editor a group of servers that hold WebDynpro ABAP application ?
Does anybody have a clue ?
Adi J.

Hi Adi,
For load balancing purposes you should use the SAP Web Dispatcher. The Web Dispatcher will know all you web application servers and will redirect the requests to the app server with more resources available.
Thus you can set the Web As hostname and port to the Web Dispatcher.
You should avoid using the message server for load balancing purposes. I can suggest you the following SAP notes for further information:
1225587 - WebDynpro ABAP with Loadbalancing in the Enterprise Portal
1040325 - HTTP load balancing: Message Server or Web Dispatcher?
945516 - Web Dynpro ABAP in a portal environment
I hope this helps.
Best regards,
Cristiano

How to deploy the webdynpro ABAP application in Portal

Hi,
Can someone provide me, all the steps involved to deploy the webdynpro ABAP application in Portal.
Thanks,
Kundan

Hi Kundan,
First create a WD abap component and then you have to integrate in the portal.
Refer this article [Integrate a Web Dynpro Application into the SAP Enterprise Portal|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/7bfea990-0201-0010-44a7-84a74971b795&overridelayout=true].

For sap mdm do i need to know webdynpro abap or java

hi
i want to learn sap mdm, then do i need to have knowledge in any of following languages?
1. webdynpro abap
2.webdynpro java
3. normal java( core java/j2ee )
4. normal abap
thanks
akhil

If you are using ABAP APIs then normal ABAP knowledge will come in handy
If u want to connect your MDM server to a portal system, then Portal knowledge will come in handy
Even the basic MDM scenarios are generally done by using Exchange Infrastructure
so basic knowledge of that is essential

Exit from Webdynpro abap application in portal environment

Hi,
I created one custom service in Webdynpro ABAP in ESS and also integrated in the portal environment
I need to put Exit button in every page ( OVERVIEW, EDIT, REVIEW). When user click on 'EXIT' button from any one of page , it should return back to PERSONAL INFORMATION in ESS Homepage.
I have used Exit plug in window , but i read in SAP Library Exit plugs will not work in portal environment.
Let me know which way i should proceed to acheive the Exit functionality.

HI,
Add the following code in action of exit and also add the application parameter which gets the area page from the portal.
Apart from this, do the configuration settings in these screens ( Define resources, Define services ) in SPRO.

Apply custom themes to WebDynpro ABAP application in Portal

Hi,
We have just upgraded the E-Recruitment to EHP4. We have two instances of ECC in which one acts as HR instance and the other one for E-Recruitmet. We have created custom themes for portal and need to apply the same for the WebDynpro ABAP applications for E-REcruitment. I have downloaded the theme and from portal and uploaded the same in MIME folder using SE80 transaction. I have also added the parameter sap-cssurl=/sap/public/themes/<my custom theme folder name>.
Also tried giving the url in application parameter as
SAP-EP-THEMEROOT=http://<hostname>/irj/portalapps/com.sap.portal.design.portaldesigndata/themes/portal/customer/<custom theme>
Is there any other way to apply themes for WD ABAP applications. I dont want to customize the standard applications and just want to apply the themes.
Any suggession on this is highly appreciated.
Kind Regards,
Vivek.

Hi,
to create theme for webdynpro abap application, use Eclipse Plugin. Please remeber to check the version of theme file before using theme.

Putting Webdynpro ABAP application on portal

Hi all,
We have SAP ECC 6.0 as the ABAP system and EP 7.0 SP 6 is the portal. I want to show a Webdynpro ABAP application on the portal which I have created in the ECC system.
I have an created an application in the back end with the following parameters :-
Webdynpro Component name :- ZTESTWEBDYNPRO
Webdynpro Application name :- ztestwebdynpro
I then created a Webdynpro ABAP iview with following parameters :-
Application name :- ztestwebdynpro
Namespace :- sap
System :- SAP_ECC_SERP (this has been tested and is working).
We also have SSO configured with logon ticket to the ECC system.
But I am getting a "Page cannot be displayed" error when I execute the application.
Any idea why this can occur?
Thanks,
Hari

Hi Hari,
So assuming you have tested the connection to the system,
perhaps another service, BSP, ITS , whatever
and that it is creating WEB DYNP ABAP iviews that is the drama.
Under EP 7.0, be sure to choose Iview type WEB Dynp ABAP.
the properties page with application parameters is:
SYSTEM -> As created to access system, available in dropdown
Namespace - > sap
Application name ->     <your WDA>    case as created in SE80
So it looks like you have entered correctly to me.
Perhaps the portal Forum has more info if you have continued issues.
regards
Phil.

Webdynpro ABAP from enterprise portal

Hi,
We have an portal which can be accessed from internet through webdispatcher. Now we have developed certain Webdynpro ABAP based based application in (R3). The WD ABAP iviews are been created on portal. But we are not able to access this application when portal is opened from internet.
The R3 is not available on internet. So how can we manage these thing so that Webdynpro ABAP can be accessed from internet?

First of all let me clear few misconceptions created from above replies.
1. You dont need public IP address for your R/3. All you need is R/3 should be accessible to webdispatcher.
2. While opening ABAP Webdynpro/ITS iviews through portal, its not portal which is trying to communicate with backend. Its the browser who does this. You can see this through http trace at browser.
It is due to 2 that your ABAP webdynpro are blocked. Bcoz no one will open R/3 to internet. Probably its blocked at firewall. Its a security issue.
For ABAP WD,
Browser > Webdispatcher > R/3.
This is how it is designed.
This is very common problem and you will find many discussions in sdn regarding this.
You can either convince your security team that R/3(ICF) should not be blocked. For which they would never agree.
Another option could be create a virtual host at R/3 and create webdynpro services(ICF services) in this virtual host and specify this virtual host in your webdispatcher.
Another expensive option could be create a Webdynpro runtime engine(WEB AS ABAP) where webdynpro applications should run and they do an RFC call with R/3. I am sure security ppl would love this.
It becomes Browser > Webdispatcher > WD runtime >(through RFC) R/3.

Implementing SRM-MDM with WebDynpro ABAP or JAVA and OCI

Hi,
I have the following situation at one of our clients.
They have implemented the SRM-MDM catalog. Via MDM the SRM server displays the catalog via ITS.
Now I want to make a WebDynpro which can talk to SRM-MDM catalog and sends the data to the shopping cart and then to SAP. How to do this? Is this possible?
It is also possible to make an iview in the portal, which reads the catalog directly from MDM. Then another iView with my own WebDynpro. Via portal eventing, I can receive which item is clicked in the catalog. Then I can show the right webdynpro view. Can I then directly call the BAPI in SRM to send the order?
What is OCI in this case exactly? Do I need that? I am new on this topic, any help is appreciated.
Sandhya

Are you basically trying to put a new User Interface (UI) on top of MDM because you do not want to use the standard MDM UI? If so, then yes you could write a custom WebDynpro and use the MDM API. We evaluated WebDynpro as an option, but instead we built a new Adobe Flex based UI that sits on top of the MDM Catalog and it totally awesome! There is a sample on our website (www.simplifying-it.net), but we are making some changes to the look/feel... however, the sample demo on the website should give you an idea.
If you have any questions, please let me know.
Thanks,
Mark

Standard Transaction Vs Webdynpro ABAP development in Portal ?

Hi All ,
I just need to know that if we do some kind of enhancement/modification in sap standard screen using the classical tools like screen painter etc. when we deploy these transaction on portal we will have those changes on the web based GUI or we need to developed the whole new development for that transaction to show on the portal ?. I know webdynpro for ABAP can be used for new developments but what if we just need a simple change on screen and we can achieve the goal using simple screen enhancement ? do we need to develop the screen again in webdynpro ? Kindly can anybody explain this ?
Thanks a lot in advance.
Laeeq.

SAP ABAP screens are used by SAPGUI for Windows and SAPGUI for HTML and are presented exactly as the screen designer lays them out. The portal can start either SAPGUI variant.
WebDynpro has nothing to do with existing SAP ABAP screens. You build new screens and then call BAPIs etc to populate the fields.
The portal can start a Web Dynpro application.
To change the look of an existing SAP ABAP screen you need to change the screen. If you want to completely change the screen, start building Web Dynpro programs.
Cheers

Debugging the webdynpro abap application from portal.

I developed a WebDynpro application and integrated in portal. I have to catch some portal events.For that i have written some code in my application. I tried to debug the application from portal by using all the available break-point types.but we could not .
Anybody have an idea how to debug a WebDynpro application from portal.
Thanks,
Kumar.

Hi
Few links to check:
External debugging is not working
Re: Debugging Abap webdynpro appln
Re: Unable to Debug WD ABAP application
Dedug is not working in Production Server.
a) Check on number of R/3 sessions opened at a time.
b) Check that user ID configured in portal using System Mapping Under 'Delegate User Administration' is the same user for which you are setting external breakpoint in backend system.

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 ABAP iView not picking Portal Theme stylesheet

Hi,
We are facing issues in integrating the WebDynPro ABAP application in Portal . The WebDynPro ABAP iView is not picking the portal theme. It is picking its actual color.
We are in EP 6 SP 14.
Can anyone let me know what can be the reasons.
Best Regards
Sid

Hello,
for the web dynpro for abap application you can create a application configuration. To create the configuration
right click on the application -> create/Change Configuration -> and once you create the configuration, it will open up in browser and you can see 2 tabs structure and parameters
In parameters tab you will find an option Force Use of External StyleSheet check the box and save the configuration. Once done with this process.
Go to the iView Properties of the applications and set the application configuration name and it would take the Portal Theme.
hope this helps.

WebDynpro ABAP application opening blank in portal

Dear All,
There is a strange issue which is being faced by one user. when the user tries to access a Webdynpro ABAP application in Portal then it opens in new window but nothing is displayed in the tray. Now when the user right clicks on the opened window->properties and copies the url from properties and pastes it in new tab (IE 8 is used) then the application opens and works fine.
The portal and backend roles are fine for the user as he can access/work when the application is opened using the copied url.
Please suggest what could be the problem for the user. For other users the issue mentioned is not there.
Regards,
Samir
