Creating Iview for Web Dynpro

Hi,
I am new to WebDynPro.I have created a Hello World Application in WebDynpro using Netweaver Developer studio.This Dynpro application has been deployed on SAP Enterprise Portal 6.0 SP9.I am able to see this application in Portal when I go to Content Administration -> Web Dynpro.
The problem is , how do I create an IView out of this web dyn pro application.When I try creating a WebDynpro IView it asks for a system name , Do I need to create a system in Portal for Portal ? If yes then what could be the WAS settings ?
Also I want to know , that is the right approach that I am following to create WebDynPro IViews.
Any help is highly appreciated.
Thanks,
Vivek

Hi Vivek,
yes, you need to create one system and corresponding alias for a WD iView. This system will define the system name where the WD application is running, it may be the same J2EE system where your portal is running, but still you have to create the system. In the iView property mention the system name and WD application name properly. Follow the Tutorial RK has suggested step by step. There should not be any problem.

Create iView for Web Dynpro Application

Hi guys,
I've created a Web Dynpro Application via NWDI and deployed to the j2ee server. Now, I'm trying to create an iView to link to that application. The steps I've done are:
1. Create iView for Web Dynpro Application
2. Select "Create iView from each application View"
3. Select my application.
That's when the error occurs at step 3. I select my application and click next, but an error msg keeps appearing telling me to "To continue, select at least one application" despite having already done so. Can anyone enlighten me on this? Thanks!
ZHenmin

Hi,
First make sure the applications runs fine standalone. Also the versions for WAS and EP are maintained correctly. Actually, this error seems to be occur for many users. Check this thread too.
Open new Web Dynpro iView in EP7
If nothing works, restart the server and try creating the iView again.

Create Transaction for web-dynpro ABAP

hi
Can you help me in creating a transaction for web-dynpro ABAP.
thank you.

If you want a SAPGUI transaction code that will launch your Web Dynpro ABAP application then I suggest creating a parameter transaction code that wraps around the SAP standard transaction code WDYID. You can use the parameter STARTMODE to decide if you launch your browser within the SAPGUI window or if it opens a new browser window. You will get SAPGUI based Single Sign On with this transaction code as well. Here is an example of a TCode I setup:

And here is what it looks like when running in place within the SAPGUI:

IView Personalization (Web Dynpro Java) for Anonymous User

Hello All,
Is it possible for anonymous user to see iView personalization (Web Dynpro Java) when personalized by an administrator? What I did was create new role and iView making available to anonymous user. This work fine meaning I can view iView using URL http://<servername>:<port>/irj/portal/anonymous . But the personalization I made to iView using administrator mode launching iView in preview mode and then using personalization dialog by choosing Ctrl and secondary mouse button to personalize is not showing. Iu2019m currently on EP7 SP15 and using iView type Web Dynpro Java for the development component sap.com/tcsecumewdenduser application name LogonHelpApp.
Any help is very much appreciated.
Many Thanks,
Gary

Hello Michael,
Yes, the Web Dynpro for Java Personalization is working perfect for non-anonymous users. The issue is when I view same iView using anonymous URL http://<servername>:<port>/irj/portal/anonymous the personalization is not showing just defaults back to the original Web Dynpro Java application settings. The iView that I created and personalized is the new Logon Help Dynpro Java application (LogonHelpApp). Is there some permissions that restricts anonymous user to view personalization?
Koti Reddy Iu2019m using the Web Dynpro for Java Administrator Personalization. Here is the documentation [http://help.sap.com/saphelp_nw70/helpdata/en/42/ed3ce7f8593eebe10000000a1553f7/frameset.htm |http://help.sap.com/saphelp_nw70/helpdata/en/42/ed3ce7f8593eebe10000000a1553f7/frameset.htm ]

Hi!
I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
I am running a newer version of NWDS:
SAP NetWeaver Developer Studio
SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
Maybe that's why things don't look the same?

Create iview for db

Hello,
Im very new in EP, I need to create iviews for accesing and retrieving data from an oracle and MS SQL Server database. Im using EP version 7.0, maybe you could guide me with this topic or give me some ideas about how to implement that. If you have some documentation about this topic would be welcome as well.
Thanks in advanced!
Luis

Hi Luis,
If you're into java you can use Web Dynpro (jdbc).
If you are used to ASP, try PDK.NET
Each of them has its own forum and you can look for
examples.

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?
Cheers,
Noel

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

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen

How to create calendar in web dynpro abap

Hi ,
how to create calendra in web dynpro abap.
Thanks in advance.
Regards, Chetan

hi,
For calender control, there is Date Navigator under "complex tab". You can just click and drag it and provide calender control.
One more easy way is to create a input field. In the context, create a node and attribute of type "D"(which means DATE). And bind the context to your input field under "values" in property window. While running the program, you will see an calender attached to lt on the input field.

How to call custom themes for Web Dynpro ABAP Application?

Hi,
I need to change the appearance of Web Dynpro ABAP application. So far I followed below steps,
1.     Created theme folder u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019 ).
2.     used program BSP_UPDATE_MIMEREPOS to dowmloaod content of u2018sap_tradeshowu2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> sap_tradeshowu2019) to desktop.
3.     Modified the themes using Eclipse Theme Editor.
4.     used program BSP_UPDATE_MIMEREPOS to upload modified themes to MIME repository u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019) .
My current URL is like http://server.name:XXXX/sap/bc/webdynpro/sap/hrrcf_a_startpage_int_cand?sap-client=XXX.
Now I want to know how custom themes called for Web Dynpro ABAP Application.
Is my approach correct?
...Naddy

Hi Naddy,
What you used is one way and even I failed when tried that method,
Instead go to SE38 - WD_THEMES - and you need to upload the zip file and you need to follow a folder structure.
it is case sensitive, atleast the zip file.
Make a zip file by name "Project.zip" -
Create a Folder Project and have the below folder structure,
1 data - all the properties files and also the designinfo file, below is the code
2 themes - (to get all the files download the theme from portal and you will have all the folders)
   2.1 ur
     2.1.1 name of the theme
       2.1.1.1 common
       2.1.1.2 csf
       2.1.1.3 r
       2.1.1.4 ur - all the css files (would be good if you can get the files from the server.)
       2.1.1.5   WSRP
3 war - empty folder
*.designinfo
isVisible=true
version=7.0.14.1.0
isDefault=false
isSapDesign=false
designName=**** name of the theme
Once done create a zip file and click on Start Import and give the path and will ask for transport request, it will take a while to upload once done as mentioned in the use the parameter sap-ep-themeroot="path"
This will resolve the issue.
Cheers-
Pramod

Coding standards for Web dynpro ABAP

Hello all,
Can anybody please help me by providing the code review checklist for Web dynpro ABAP?
Thanks and Regards,
Rohini Shankar

Hello friend,
WebDynpro     *
1     Do not implement Data intensive operations in UI layer
2     Avoid database selects in the WebDynpro code.Use the corresponding BAPIs ,Methods
3     Are ABAP OO Classes like Assistance class are being used for application coding ?
4     Are Windows/Views only used for the sole purpose of hosting views and context?
5     Are a reasonable number of views put in a single WD Component instead of creating multiple WD Components ?
6     Unneccessary usage of dynamic programming and dynamic component avoided
7     Are singleton nodes used in case of nesting in the context ?
8     Is deep nesting of containers, Groups and Tabstrips avoided ?
9     Is the UI element TreeByKey or TreeByTableNestingColumn used instead of the Tree UI element ?
10     Is the checkbox "Accessibility Checks Active" ticked in the WD Component properties
11     Are the WD Component Instances deleted when no longer needed (IF_WD_COMPONENT_USAGE=>DELETE_COMPONENT)
12     Are the OTR texts defined for all the labels, texts(where ever appropriate) in properties of all the UI elements
13     Has the Generation limit been checked for all the components developed
14     Sufficients commets are written at the beginning of every major block to explain the processing logic.
*Error Handling     *
1     Is SY-SUBRC checked after CALL function modules
2     Use Assertions if you face unexpected errors which usually never ever occur!
Extended Check and Clean Up
1     Have following been removed :
     ·      Unused variables
     ·      Unused text elements
     ·      Unused tables from TABLES statement
     ·      Commented out parts of the code
     ·      Code segments which do nothing
2     Is extended program check completed and all errors/warnings removed
These are the things which i used for my project.

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.
