Implementing Logging in Web Dynpro

Hi All,
I was able to define a new Log Controller of type location and able to write the traces(logs) into the default trace file according to the severity.
But When i change the severity for the exsisting Log Configurator "com.sap.tc.webdynpro" which was defined by the WD framework its not getting reflected. Only the error messages are written.
Other thing is i defined a new path for my own trace(log) file in the Log Destination -> Pattern as "C:\usr\logs\mylog.txt" but all the messages are written to the default trace file.
How can i implement my own trace(log) file and write my own trace(log) entries to it.
Thanks
Gopal

No. There is no container for displaying SAPGUI inside of Web Dynpro. The closest you could get to this would be the SAPGUI for HTML running inside an iFrame, but that is completely different than what you are talking about (and also not recommended). Dynpro/SAPGUI output is a very different technology thatn Web Dynpro and the two can't be mixed directly. You need to find a way to extract the data you need without any calls to visualize it.

ESS Implementation based on Web Dynpro Abap(WDA)

Hi All,
I would like to know if anybody can share experience in implementing ESS based on WDA using ESS business package 1.50 on portal. I would like to know how different this implementation compared to configuration using Web Dynpro Java(WDJ).
Thanks in advance.
Khairul

The difference can be due to deployment, ie if you want Portal to be used if you are already not using ECC 500 or 600
You can be a ramp up customer or wait for it wide release in march end or april
the key difference is most of the customisation of the roles can be done from backend!
Just read these links for better understanding of this

Problem: Changing Language for Web Dynpro Java within NW Portal (i18n)

Hi Experts out there,
I hope all you had a nice Christmas and a big New Years Eve :)!!!
i got a challenge for you about WD Java and internationalization (i18n)
Here is the scenario:
We are using a SAP NetWeaver Portal 7.0 and my task is to implement some smaller Web Dynpro Applications.
These Applications must be i18n conform, so i just created (according to the corresponding WD Java tutorial) some ".xlf" files.
Okay...Everything is working fine. The user can log at the portal and the application is displayed in his language, which is "english" or "german". (the application is just a simple form)
So far so good...Now here comes the point where it's getting tricky...
When the user wants to change his assigned language (of the portal user) he can use the "personalize" button in the Masthead (-> change portal language). All the portal content should now be displayed in his new chosen language.
For example the user is logged into the portal with "german" as portal language and now changes his languages settings into "english". After this everything in the portal (navigation, portal iViews ) is displayed in the changed language (from english into german) ...
BUT: my Web Dynpro Java Application stays as the original languages setting was. That means the whole portal is now english, but my WD Java Appl. stays german .
Only if the user logs of and logs in again, the WD Java Appl. is displayed in the corresponding portal language...
VERY Strange?!?!
Can anybody give me a hint how to solve this problem?
I guess i have to re-initiate the Web Dynpro Application some how ...(like killing the application and restarting it ...) but is just a "weak guess"...
Any Help / Hint is more than welcome !!!
Cheers
Stefan

Hi Stefan,
This correct see SAP Note [947081|https://service.sap.com/sap/support/notes/947081]
If the locale for the Web Dynpro iView is changed in the portal (through portal personalization), this is not reflected in the running login session. The user needs to logoff and login again, in order to see the locale change in the Web Dynpro iView.

Leo

Accessing ABAP Functions in Web Dynpro

Hi all,
for testing reasons I would like to implement a simple Web Dynpro Application which access APAP functions (or BAPIs) on a remote SAP backend system. The problem is that I dont have a SAP backend system
There is a tutorial :
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526</a>
which states some prerequisites.
My question:
Is it possible to comply to all these prerequisites by installing NetWeaver Preview and minisap as remote SAP backend system ? Where can I get minisap ?
I'm quite new to SAP so I'm al little unsure which part belongs where.
Maybe someone can give me a hint.

ISR in Web DYnpro ABAP

Hi,
I am new in Internal Service Request (ISR) and I need to understand if it is possible to implement it using Web Dynpro ABAP views.
I have seen a sample Web Dynpro application APB_ISR_UI_FORM. I would also like to know if it is easier to implement ISR in Adobe forms than Web Dynpro ABAP.
Thanks & Regards,
Preethi.

Preethi , interestingly the APB component you mention is part of new work done by SAP to port the ISR tools to Netweaver 7.02, therefore independant of ECC. The more complex your UI is the more useful Adobe form input becomes because it is highly precise in its presentaiton.
Cheers

Web Dynpro JAVA VS. Web Dynpro ABAP

Hi,
I'm interested in advantages and disadvantages of WD JAVA & WD ABAP. Could anybody give me some "detailed" information about it?
We need any information you can give us.

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

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.

The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions
hope it helps

A question on component design in Web Dynpro

Hi experts,
We currently working on our console which we want to implement them using Web Dynpro framework.
During design time, questions have been raised: we have like 100 EJB methods for our application, about 8 EJBs, we want to have faceless component taking care of persistence.
The question is what is the best way to distribute the methods in terms of performance and supportability (for ease of development )? We discussed the following options:
1.     One faceless component with one component controller implements 100 methods (maybe this is the worst)
2.     Many faceless components, one for each EJB, here the question came up: performance because we have a tab strip in the UI that accesses 6 EJBs, would it take a long time to load/unload these components every single time we switch among the tabs ?
3.     One faceless component with one custom controller for each EJB, here the question is: can we expose the custom controller in other to use them in the tabs? Compared to option 1 we clearly separated the methods, so it is easier to support. Furthermore we should have a performance gain since the custom controllers are only loaded on demand.
What do you think?
Regards,
Dat
Edited by: Dat Triet Banh on Jul 4, 2011 4:47 AM

Hi
Better to segregate the EJB's and put it in seperate controller keep atmost 30 in one controller (you have around 3-4 component ). Any component which is going to use in other component is basically based on create on demand priniciple automatically by framework.
or
as given in point third create a component , with say 8-10 Custom Controller implement the all the methods and put a same method signature in Component Controller, call the same through interface thats it.

HTML, JavaScript, Applets possible in Web-Dynpro Applications?

Hello Community,
I'm developing a JEE5-Application using Web-Dynpro for the User-Interface. Web-Dynpro works fine for the most functions and processes of the application. But there are some special requirements i don't know to implement them using Web-Dynpro.
So my question is, if there is the possibility for:
using HTML-Code in a Web-Dynpro UI-App (the HTML dynamically generated by Web-Dynpro)
using JavaScript in the Web-Dynpro UI-App
using Java-Applets (for example to interact if local computer resources)
using an HTML-Editor for editing Texts in the Application (for example freeware Edtior fckeditor)
or do i have to use JSF in that case?
regards
Matthias

Hi Matthias,
I will answer your question point wise, in short:
1) Using HTML-Code in a Web-Dynpro UI-App (the HTML dynamically generated by Web-Dynpro)
Ans: it is possible to put the HTML code in the WebDynpro UI App. Use the IFrame Ui element to do the same. See this:
http://help.sap.com/saphelp_nw04/helpdata/EN/e9/7652a84fada444bd11ca73670ce7dc/frameset.htm

Displaying HTML in WebDynpro View
2) Using JavaScript in the Web-Dynpro UI-App
Ans: Not Possible.
3) Using Java-Applets (for example to interact if local computer resources)
Ans: Not Possible.
4) Using an HTML-Editor for editing Texts in the Application (for example freeware Edtior fckeditor)
Ans: Not possible.
I hope this helps!

Want docs for Web Dynpro ABAP

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

Hi,
Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
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).
Web Dynpro offers the following advantages for application developers:
? The use of declarative and graphical tools significantly reduces the implementation
effort
? Web Dynpro supports a structured design process
? Strict separation between layout and business data
? Reuse and better maintainability by using components
? The layout and navigation is easily changed using the Web Dynpro tools
? Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
? Automatic data transport using data binding
? Automatic input check
? Automatic operation of the Web Dynpro application using the keyboard
? User interface accessibility is supported
? Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
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
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
? Data flow between the front end and back end
? Layout of the user interface
? Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
? An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
? An interface for calling Web services
? A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
? The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
? The view is responsible for the representation of the data in the browser.
? The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.

Portal SSO Web Dynpro ABAP

Hello,
We have implemented a long time ago, Portal 7.0 SSO and AD and it works perfect.
Now, we implemented the first web dynpro abap, with most users, wda application works fine, but for some users to access the same window will appear loguin.
In SAP, we set the parameters:
login/create_sso2_ticket = 2
login / password_change_for_SSO = 0
If the user with the problem, uses another PC, it can access the application normally. We imagine it's some configuration of PC or Internet Explorer.
Anyone ever happened something similar?
We can help us solve this problem.
Regards,

We solve the problem by adding an exception proxy.
Portal is accessed by a dns (http://name), the solution we found is to add the exception of proxy (http://name.com) and it works perfect.
Thank you very much,
Regards,

Custom Layout for Web Dynpro Proxy page

Hey all
I have a requirement to display 4-5 Web Dynpro for ABAP iViews on a page.
I have the option of using the standard PRT page to display these iViews for which I can create a custom layout using com.sap.portal.layouts.default.par and the simple JSP layout file in it.
However, they should really be on a Web Dynpro Proxy page but custom layouts created using above component wont work.
In the document [Integrating Web Dynpro and SAP NetWeaver Portal|https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/0c7b2f25-0c01-0010-f2a2-f8a65a9dcad9] it says -
Within the SAP NetWeaver 04s release it is not possible to define application specific page layouts for Web Dynpro pages. Within the SAP NetWeaver 07 release this will be possible. Layouts for Web Dynpro page are implemented then as Web Dynpro components implementing a special ILayout Web Dynpro component interface.
Has this been released as yet?
Anyone find the APIs or workaround for this?
Cheers

I have the same question, but can't find any good solutions for this.
For standard portal applications you can use com.sap.portal.design.layouts and modify layouts via JSP. But all webdynpro proxy pages are using their own layout.
I'd like to change that layout too.
Anyone?

Noel
