U0093Class not foundu0094 for Web Dynpro API class

Hi,
After installing Web AS 6.40 (Java) and the Netweaver Developer Studio (2.0.12) I tried a simple hello world example (just a WebDynpro view with a static text, without any further view elements or program logic).
When deploying and starting I constantly receive the following runtime message (top of stacktrace):
java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/progmodel/api/IWDEventHandlerId.
IWDEventHandlerId is a class delivered with Netweaver Developer Studio. It should be found as further down in the stacktrace I read
at com.sap.tc.webdynpro.progmodel.generation.ControllerHelper.createDelegate(ControllerHelper.java:68) and
at com.sap.tc.webdynpro.progmodel.generation.DelegatingInterfaceView.<init>(DelegatingInterfaceView.java:44).
Classes ControllerHelper and DelegatingInterfaceView are obviously found and they are contained in the same jar file as IWDEventHandlerId! The jar file is \JDT\eclipse\plugins\com.sap.tc.webdynpro.runtime\lib\_webdynpro_progmodel.jar.
Has anyone had a similar problem and found a solution / a workaround?
Thanks in advance
Thomas Bellinghausen

Hi Thomas ,
Please repair and repload the project and deploy&run.

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

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

JCO Connection for web-dynpro tutorials (EP 6.0 SP9 downlaod from SDN)

Hello,
I have a question regarding JCO connections for web-dynpro example/tutorials. I have installed WAS 6.40 sneak preview from EP 6.0 SP9 download from SDN. Installation instruction says: Choose "No SLD available"
but the web-dynpro example/tutorial asks to create JCO connections by going to web-dynpro -> content admin..etc on http:<host>:50000..Here, all the tabs relating to creating JCO connections appear to be "protected" on my screen. so I can't do anything further. By going to http:<host>:50000/sld, I also tried to add SLD server..but that is not helping. There is some "import" button, but which CIM file (in which folder etc) am i supposed to import for a simple test system? What are the steps for a bare minimum setup so that I can use the WAS 6.20 system at work-place as my backend & try out the web-dynpro examples? Do I really need SLD setup? Where is documentation about all this after one installs the WAS 6.40 JAva? I was expecting it somewhere at least in the eclipse IDE help-documentation..None of the web-dynpro tutorials explain this !
thanks

Thanks everybody.
NagaKishore, after doing all the steps, when I goto
localhost:50000-> web dynpro -> content administartor, and try to "maintain JCO Destinations" I am getting this error: (full stack trace not included)

Cant find control pallet in se80 for web dynpro

hi,
i can not see control pallet in se80 for web dynpro. what i have to do for it?

I think you have to use the Objekt-Tag like
<OBJECT codetype="application/java" NAME="theNamer"
WIDTH = 100 HEIGHT = 100 classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = NAME VALUE = "theName" >
<PARAM NAME = CODE VALUE = theClass.class" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3.0">
<PARAM NAME = MAYSCRIPT VALUE = true >
<PARAM NAME="scriptable" VALUE="true">
<EMBED NAME="theName" MAYSCRIPT=true scriptable=true type="application/x-java-applet;version=1.2" java_CODE = "theClass.class" WIDTH = 100 HEIGHT =100 pluginspage="http://java.sun.com/products/plugin/1.2/plugin-install.html" </EMBED>
</OBJECT>
Then you can acces the JApplet with document.theName.method();

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
I am using NW 701

Shooping cart creation in SRM 7.0 using web dynpro ABAP classes.

Hi,
We have recently upgraded to SRM 7.0 from SRM 4.0. We are using customized portal application for the creation of the shopping cart.I am planning to create custom FM which will use the standard Web dynpro ABAP classes to create the shopping cart.
Could you please guide with the classes that are need to be implemented and the sequence of the classes used in the shopping cart creation.
I think these are the classes that are used in the standard web dynpro ABAP component.
CL_FPM_EVENT ->                  Creates an instance of this class based on an event ID.
CL_BADI_FLT_DATA_TRANS_AND_DB -> Data Handling: Transport and Database.
CL_EXITHANDLER ->               Class for Ext. Services Within Framework of Exit Technique.
CL_EX_BBP_DOC_CHANGE_BADI ->     BAdI Class CL_EX_BBP_DOC_CHANGE_BADI.
CL_BBP_OBJECTS_ACCESS ->         Access Functions for Object Types.
/SAPSRM/CL_PDO_BO_SC ->          Shopping Cart BO.
Your expert comments will be appreciated...

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.

Alternative for web dynpro for abap

Ok,
After a previous question we found out that if we want to use web dynpro for abap, we should upgrade to NW2004S.
Now, are there alternatives for web dynpro for abap?
currently (WAS 6.20 - R/3 4.7)
Thanks in advance,
Tom

Hi Tom.
On 6.20 you can use BSP. But this is not a real alternative to WD4A when lookin at the comfortable development. But a alternative as web application technology.

Adobe Flash Islands for Web Dynpro ABAP Data Binding problem

I have downloaded the NetWeaver 7.1 Trial (includes Adobe Flash Islands for Web Dynpro ABAP). I try to create a very simple FlashIslands component running within the Web Dynpro Application, everything looks good. However, all binding to the Flex component is not working. Does anyone know why?
Since it's trial version, I login as BCUSER into NSP system. When I load up the build-in sample, such as Chart Demo, the binding to Flex seems working. I suspect if it has anything to do with package? I could only create my Web Dynpro under the $TMP package, as all the build-in sample are defined in SWDP_DEMO.
Please help.
Alan

hi,
Check out this link. It will give you an idea how to integrate Aobe island comp with web dynpro.

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 .

BASIS settings for Web Dynpro ABAP

Hi Team,
I need to know of settings required (configuration) for Web Dynpro ABAP. Please help me on this. Please also let me know of how these settings can be implemented.
Regards,
Amit

Hi Amit
First you have to check the domain, if it is not maintained then maintain the domain in your operating system.
To do this, follow below path :
-- Right click on My Computer >> Computer Name tab >> Click Change >> Click More >> Enter your domain name in the format u201Ccompanyname.comu201D in the section Primary DNS Suffix of this computer
u2013 Click OK
And then go to your SAP to set "icm/host_name_full" in transaction RZ10.
Choose your Instance profile, click on Extended Maintenance and then click on the Change button
As "icm/host_name_full" is not present for you, add it by using the New parameter button
set the value to <hostname>.companyname.com (hostname can be seen through transaction RZ11).
Save and activate your profile and after that restart the R/3 server to take effect.
Hope this will solve your issue.
Regards
Brillion
