A quick question about WebDynpro SLD and R/3 with concurrent users

Hello ,
I have a very quick question about Webdynpros and SLD connecting to an R/3 system, when you configure a webdynpro to connect to an R/3 system using SLD, you configure a user name and password from the R/3 for the SLD to use. What I would like to know is when I have concurrent users of my webdynpro, how can I know what one user did in R/3 and what another user did? Is there a way for the users of the web dynpro to use their R/3 credentials so SLD can access the R/3? Like dynamically configuring the SLD for each user?
- I would like to avoid leaving their their passwords open in the code ( configuring two variable to get the users username and password and use these variables as JCO username and password )
Thanks Ubergeeks,
Guy

Hi Guy
You will have to use Single Sign On to achieve this. In the destination you have defined to connect to R/3 , there is an option to 'useSSO' instead of userid and password. This will ensure that calls to R/3 will be with the userid that has logged into WAS. You wont need to pass any passwords because a login ticket is generated from WAS and passed on to R/3. The userid is derived from this ticket.
For this to happen you will have to maintain a trust relation ship between R/3 and your WAS ,there is detailed documentation of this in help files. Configuration is very straight forward and is easy to perform

Doubt about webDynpro windows

HI Experts,
I have small doubt about webdynpro windows.
1) If i have only one application in webdynpro DC , what is use of using multiple windows.
2) If i have multiple windows in a DC which has single application, how i can i navigate between windows?
3)if i have multiple applications with multiple windows, then how will i know which window belongs to which application.
4)If i have multiple windows and multiple applications, then how can we navigate between windows? It means navigation betn windows and navigation betn applications...?
Please explain me, i browsed in SDN, i found the threads but they are explaining my doubts exactly
Thanks in advance.
Regards,
Bala

Hi.
Simply the Window is part of Web Dynpros public interfaces, and are needed whenever you want to access a graphic component from outside of your web dynpro component.
Web Dynpro uses the MVC design pattern. Model View Control.
In order to reuse components, Web Dynpro exposes the View and Controller to the outside world.
Internally the View and Control in MVC is just that:
Views
Component Controller and Custom Controller.
Externally the View and Control are exposed as
Interface Controller and Interface Views. The Interface View is the external part of a Window. (When a Window is created, an associated Interface View is created).
So, to be able to actually see anything from a Web Dynpro application. The browser would access a Interface View that opens the Window with some view in it.
An other example is that you have two Web Dynpro projects, where the first one have a View with an integrated view from the second Web Dynpro. The integration would be through the Interface View again.
Internally in your Web Dynpro component, you can use the views directly (i.e. navigate between views).
Opening an external popup would generate a new browser window. In order for the new browser window to display anything it would need to access an interface view. That's why you need to create a separate Window when you want to use a popup.
Regards.

Give me description about WEBDYNPRO

give me description about WEBDYNPRO

Hi,
https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro
There is a separate section for Webdynpro on SDN.
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.

FYI. Problem about webdynpro embedding

Dear Expert:
I encountered a problem with webdynpro embedded in portal.
Let's make it simple,
the source of a UI element Image in the webdynpro binds to a link   -> ftp://...../test.jpg
in my program I change the link dynamically after some action.
Everything works fine if I run this webdynpro.
But the strange thing is when I embed the webdynpro into portal, the image could not be displayed, even
it could not be shown if I bind it to the fixed link. (ftp:///)
I tried other source like http://///test.jpg, it works in portal,   but how FTP source fails?   I check there is no cache.
Thanks very much for your insight.

Please check your application log and/or default trace to see what exactly happened. It might have something to do with security (depending on your landscape between portal, Web AS, FTP site), how you generated the URL in your WD application. Please refer to this doc (p.18)

About webdynpro actions

hi to all
iam little but confusion among
ACTION ,, EVENT., EVENT HANDLER METHODS
can any one give me description about all these
thank u inadvance
ratan

Hi Ratan,
Method can be void and it can be return type.
Method with Event: it perform some system actions such as click, enter etc..
Action it performs system events. for example. You can use actions with UI Elements where as methods are not.
For example: Submit Button
onActionSubmit()
Note: Method with event and Action both are almost Similar
To avoid Confusion:
Use actions when use UI Elements
Use methods if you want write individual methods

About webdynpro

hi guysfirst of all i thank u all guys out there..
for extending ur support.
here i have a doubt
we can develop webdynpros for abap on following environment
1. ecc6 or crm 5( i mean which are on was abap 7)
2. the two files which i have downloaded from sdn.sap.com
that is was 7 + webdynpro UI
so here my doubt is what is the difference in therse two environments
ok.. some how we have developed webdynpros for abap then what we do with that webdynpro for abap? do we need publish its url so that people can have access to our server which is ecc6 or crm5?

hi,
I suggest you to kindly go to the elearning link in sdn.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/b1203f5e-0501-0010-bb88-915402c954f2 [original link is broken]
there are a lot of documentation and saptutors available.
you do not require to publish webdynpro abap applications.
If you are providing it as iview links in portal.
Or if you check sicf transaction you will get the node of your webdynpro abap application.

reward points would be appreciated

A question about primary study

I have the frame1 and a button in it ,i want to click the button to show the frame2.
How can show the frame2,which method shall I invoke.

Yeah...as Ikeda says,
the class that extends Frame (called say, Frame2) needs to be instantiated in the actionPerformed method that gets invoked when the button is pressed.
public void actionPerformed(ActionEvent ae)
Frame2 f2 = new Frame2();
// This should invoke the Frame2 constructor and create a frame and also set the visibility to true.
// Once this is done, the above statement should automatically display the other frame.

About webdynpro techniques!

I have to read data from reference database(read-only) (SAP) by calling Function to access database then I have to calculate and store it somewhere and other person can access and get this data. I wonder where can I store these data. Does web-dynpro support any techniques to do this?

Poll: Development in ABAP Objects / Webdynpro vs. classical Dynpro

Hey there ABAP developers,
I just want to ask if you can give me one or two minutes of your attention for two poll questions.
At the moment I´m writing my master thesis about the development of a monitoring tool in ABAP. One of my bigger chapters is about the decision, which programming paradigm should be used for new development projects in SAP. And another important one is about WebDynpro vs. classical Dynpros.
Because of the fact, that I can´t create any polls in here, I just started this discussion and hope for many replies .
It would be very nice if some of you could give me an answer to the following questions (only 2 ), so that I can maybe use the result of this poll in my master thesis, if there are enough responses.
1. What percentage of new development projects are you developing in ABAP Objects? (Not to be considered small reports that just runs for only one time)
     A. 0 %
     B. less than 25%
     C. 25% - 49%
     D. 50% - 75%
     E. more than 75%
2. Which GUI technology do you prefer?
     A. Classical Dynpro
     B. WebDynpro
     C. Business Server Pages (BSP)
     D. others (please mention)
I want to thank you in advance for answering the questions,
Best regards,
Christoph

Hi,
Present SAP Implementation projects are very rare, maximum projects are support and up gradations only .
If they want Implement the SAP newly , defiantly they should creating ABAP Objects.
Why Because ABAP Objects are Object Oriented Concepts, so, for future reference and re usability..etc .
Now Come to the First Quetion.
if it is implementation project   ABAP Objects are 25% - 49%.
if it is Support project ABAP Objects are 25%
Now Come to the Second Quetion.
Depend upon Reqmnt, but Most of the Applications are Webdynpro . i.e 70%.
Remaining 30% All ( BSP and GUI ....Etc..)
This is my opinion.

Webdynpro application history navigation

Hi people,
I have a question about webdynpro navigation. I know that der are many threads
about this topic, but I think I don't find an answer for my question:
The scenario: I have a webdynpro application running in the enterprise portal.
The application is linked with ONE IView in the portal (and running on a different
application server). The application has about 20-30 webdynpro views, which are arranged
in different viewsets.
I need a navigation history (similar to the history in common web browsers like iexplorer)
in my application. Because of the multiplicity of navigation possibilities within the
application, it doesn't make sense to programm a static view navigation.
My question: Is there a standard way in webdynpro to realize my needs? Can I use the
PortalNavigation API, or is this API only for navigation between portal IViews? Can I
use the Breadcrumb Navigation UI Element?
I'm developing on a WAS 7.00 (Netweaver 2004s).
Thanks in advance for your effort,
regards,
Thomas

Hi,
You can use PortalNavigation. Take a look at the historyMode parameter of the navigateAbsolute() method. Find the documentation <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/56/b4544251dcc153e10000000a1550b0/frameset.htm">here</a>.

Search for ABAP Webdynpro Best practice or/and Evaluation grid

Hi Gurus,
Managers or Team Leaders are facing of the development of SAP application on the web. Functional people propose to business people Web applications. I'm searching for Best practice for Web Dynpro ABAP Development. We use SAP Netweaver 7.0 and an SAP ECC 6.0 SP4.
We are facing of claims about Webdynpro response time. The business wants to have 3 sec response time and we have 20 or 25 sec.
I want to communicate to functional people a kind of recommendation document explaining that in certain case the usage of Webdynpro will not be a benefit for the business.
I know that the transfer of data, the complexity of the screen and also the hardware are one of the keys but I expect some advices from the SDN community.
Thanks for your answers.
Rgds,
Christophe

Hi,
25s is a lot. I wouldn't like to use an application with response time that big. Anyway, Thomas Jung has just recently published a series of video blogs about WDA performance tools. It may help you analyzing why your web dynpro application is so slow. Here is the link to the [first part|http://enterprisegeeks.com/blog/2010/03/03/abap-freakshow-u2013-march-3-2010-wda-performance-tools-part-1/]. There is also a [dedicated forum|Web Dynpro ABAP; to WDA here on SDN. I would search there for some tips and tricks.

How can I call RFC FM from webdynpro application for ABAP? Please help!

Hi Experts,
I have a requirement where I have to make a call to RFC enabled function module passing some data from webdynpro for ABAP application. How can I achieve this? Any tutorial or links or docs will be very helpfull.
I have seen some tutorial on Adaptive RFC but it talks about webdynpro for Java.
Can I use "Call function XYZ destination A10" statement in webdynpro for ABAP application?
Thanks
Gopal

am doing same thing for my current SRM implementation.I am taking data to SRM server from another R/3 server .
This is solution I have used
1) First of all I have made ABAP connection in SM59 .
Go to SM59 .In ABAP Connection creat ABAP connection with system with which u want communicate .
Eg I am connection with Systems PB1.
So i developed Connection call PB1CLNT800.
2) In my requirement I have taken data in my context from another r/3,
I have give called RFC in my supply function of node.
Call to RFC is as usual.
In my case,
CALL FUNCTION 'RFC_MATNR'
DESTINATION 'PB1CLNT800'
TABLES
IT_MATNR = IT_MATNR.
Onwards I have read my itab IT_MATNR and populated data to context.
Hope solution will serve your purpose.
Give point if it works .If any problem i have other ways.
Cheers

How to include a Bapi or a TCD into my Java WebDynpro

Hello all,
Yesterday I finished my first Java WebDynpro Application ("Welcome"). That means, I am a beginner
But like I mentioned in the subject, I need Information about, how I can include a Bapi or a TCD into my Java WebDynpro.
This could be any information: verbal statements, Powerpoints, How-To-Guides, *.pdf's or something like that.
Thank you in advance and regards,
A. Cetin

Hello Ayşegül
You can find some information about webdynpro below link. But I dont understand exactly what do you want to do? You can call any BAPI easily inside webdynpro java.

Interfaces in webdynpro java

Hi all,
I have a doubt about the programming in webdynpro java interfaces . what is the main concept underlying in context of a particular view, why to use the follwing code for referring to context attribute
IPrivate<viewname>.I<NodeName> node = wdContext.node<NodeName>();
IPrivate<viewname>.I<NodeName>Element ele = node.create<NodeName>Element();
ele.set<Nodeattribute>("xxxxx");
node.addElement(ele);
Is the context is a Interface ?
please explain me the above code or any relavant documents for Interfaces implementation in webdynpro java
Total no of interfaces in webdynpro java list.
Thanks
prasad

Hi Prasad,
Web Dynpro controller has a data storage area known as the context. This is a hierarchical repository within which all runtime data used by the controller is stored..Context is not an interface in the code you are trying to set some value to the context attribute by getting that particulat context node reference.
Find the below links which explains you clearly about webdynpros and interface concept
