Just a question how this application share its data....
We want to add a new screen and need to share data...
...and can see that the Central application controller interface IF_FPM_APP_CONTROLLER is placed in web-dynpro component PLMU/WDC_FRW_APPL_CNTRL.
And no IF_FPM_SHARED_DATA ?
Hmmmm.
Why ?

Few basic ques on Web Dynpro

Hi All,
I have few ques on Web Dynpro basics.
1. Why is Web Dynpro said to have language-neutral metamodel.
2. What is meta-model.
3. What is declarative programming approach.
4. Why is a dictionary used. The simple type and a structure can also be declared in a Controller. Is it just a Global Declaration.
5. Where does the code of dictionary reside.
Shall be grateful for the answers.
Regards
Nikhil Bansal

Hi Nikhil
Here is the answers for your questions.
1.Why is Web Dynpro said to have language-neutral metamodel
A.the user interfaces developed in webdynpro is platform independent because of meta model/data generated by webdynpro framework is independent of all languages.This metamodel you can transfer to any system so that the application is executed in that system.So generated meta data is independent.
2.What is meta-model.
Metamodel is data about the application.Webdynpro framework have seperate tools to generate this metadata in xml files.These files contains all information about your application.Views,components,actions every thing.
Metadata/model means data about the data in general
3.What is declarative programming approach
Declarative approach is the one with out coding most of the things required to implement User interfaces (design,appearence,data) are specifying at design time by choosing right properties.So this eliminates most of the coding.So this is the declarative model.
4.Dictionary
This is again having two types like simple and structure,Here basically we store the data in dictionary datatype or populate the data in this type in runtime.Usually this datatypes are used to display the data in dropdown box or to display large data.
5>Where does the code of dictionary reside
The Dictionart classes are generated by the frame work for simple type,For complex type the data you are populating in view controlleres depending upon the conditions
For clear classification

Are there any standard web dynpro ABAP or JAVA for material creation(mm41)?

Hi SDN,
I have got the requirement to provide Web Dynpro application for material creation (transaction code is MM41) and I would prefer to enhance standard Web Dynpro more than develop from scratch. Now I got only the Web dynpro ABAP component for create sales order called "LO_OIF_MAIN_COMP" and GUI HTML for purchasing order that come with business package Eh4.
Anyone who know please kindly help me.

>but I afraid that I'm not able to find out what is its component name from application
You could just lookup the WD Application in SE80 and then it will show you the component name. From SE80 choose Edit Object from the toolbar. Go to the Web Objects tab in the dialog. Type in the WD Application name and hit enter. You will then see the details of that application.

As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.
The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.
Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
First of all start doing SAP SDN tutorials .

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 .

If you need some standard examples then do WDR* and you'll get a big list in se80 transaction. Also SWDP_DEMO is a good package to refer to. Check for WDR_TEST_UI_ELEMENTS and WDR_TEST_EVENTS for UI operations and their various events.

Web dynpro material

Hi
iam new to web dynpro. can anyone please provide me some good learning notes for wd.
thank
sai.

Well where to start?
SDN has a whole section for this topis here:
https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro
At first help.sap.com is always a great start with its tutorials:
http://help.sap.com/saphelp_nw04/helpdata/de/15/0d4f21c17c8044af4868130e9fea07/frameset.htm
Then you will find a couple of very good artikles here in SDN, just to mention a few:

And there is also a good book out about this stuff called Inside WebDynpro that i can highly recommend.
And this was only the Java stuff. With NetWeaver 2004s there is now also WebDynpro for ABAP.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/63a47dd9-0b01-0010-3d8e-de27242bf011
And you will find a lot more of this here in SDN. Just search for it if you made it through these few items.
Have fun,
ok

How to create a user in UME Database using web dynpro java custom application

Hi,
Can you please suggest me how to create a user in UME Database using web dynpro java custom application.
My Requirement is user can register his/her user id in SAP Portal 7.3 UME database.
Please suggest me.
Thanks and Regards,

Hi Amit,
Generated Documentation (Untitled)
This is what you're looking for, there's no real cook-book -- though Amey mentioned there might be some material on SDN, perhaps some tutorials.
You should be looking into com.sap.security.api.IUserFactory, methods newUser(String) which gives you and IUserMaint and commitUser(IUserMaint, IUserAccount) -- IUserAccount can be obtained using com.sap.security.api.IUserAccountFactory, method newUserAccount(String)
Hope it helps,

Using the XML returned by XI to populate table in Web Dynpro UI

Hi,
In Web Dynpro,I have a scenario where i have to generate reports. For this, I enter the "Customer number", "Date" & "Item No" in 'Generate report' page and hit the "submit" button. These details are sent as XML to XI which interacts with the ABAP R/3 system, performs the search and returns the search results as an XML
Now, I want to display search results contained in this XML by populating it in a table.
From, the point where the XML is returned by XI, could you please tell me the step by step process to populate this XML in a table. Please include code, if any.
Kindly help.

Hello Sandeep,
Create context node with following strucure:

result
-CustomerNumber
-ItemNumber
-Material
-OrderDate
Create data handler:
public class XIDataHandler extends DefaultHandler {
 private String lastAttribute;
 private IWDNodeElement newElement;
 public void startElement(String namespaceURI, String localName, String rawName, Attributes atts) {
 if ("Result".equals(localName)) {
 newElement = wdContext.createResultElement();
 wdContext.nodeResult().addElement(newElement);
 } else {
 if(null!=newElement)
 lastAttribute = localName.trim();
 public void endElement(String namespaceURI, String localName, String rawName) {
 if ("Result".equals(localName)) {
 newElement = null;
 lastAttribute = null;
 public void characters(char[] data, int off, int length) {
 if(null!=newElement && null!=lastAttribute) {
 final String value = new String(data, off, length).trim();
 if(!"".equals(value)) {
 newElement.setAttributeValue(lastAttribute, value);
And parse XML in appropriate place within your application:
try {
 SAXParserFactory factory = SAXParserFactory.newInstance();
 SAXParser parser = factory.newSAXParser();
 //Loading XML from string (XI_DOCUMENT), change if source differs
 StringReader sr = new StringReader(XI_DOCUMENT.trim());
 InputSource is = new InputSource(sr);
 parser.parse(is, new XIDataHandler());
} catch (Exception e) {
 final StringWriter sw = new StringWriter();
 final PrintWriter pw = new PrintWriter(sw);
 e.printStackTrace(pw);
 wdComponentAPI.getMessageManager().reportException(sw.toString(), true);
Create table and table columns and map your context to it.

Using External JARs in a Web Dynpro Project

Hi,
I'm having some difficulties building and deploying a Web Dynpro application that uses the Apache JaxMe libraries. We're using SP11 of Developer Studio and WebAS and we're using JDI Scenario 2+ for building and deployment. Thus far here's the procedure I followed:
1) Created a DC of type "External Library"
2) Added the necessary jars to the "libraries" folder of the External Library DC project (the jars that I added were jaxme2-rt.jar, jaxme2.jar, jaxmeapi.jar, jaxmejs.jar, jaxmepm.jar, jaxmexs.jar, xercesImpl.jar, xml-apis.jar all of which were pulled from the Apache JaxMe implementation download)
3) For each of the jars in the libraries folder I right-clicked, selected Develoment Component then clicked "Add to public part"
Then after reading this note:
https://websmp206.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=012006153200000038152005
I created a J2EE Library Component DC following these steps:
1) Created a new DC of type J2EE Server Component / Library
2) Added the External Library DC that I had just created as a "Used DC"
3) Edited the DC so that it is used a Build Time and Run Time
Finally I went to the Web Dynpro application and included the J2EE Library Component DC as a Used DC at build time and run time.
I was able to build all of the project successfully (doing a DC build for each) then I was able to succesfully deploy the applications to my local development WebAs (by doing a DC deploy for both the J2EE Server Component and the Web Dynpro application) The problem is that at runtime the Web Dynpro application cannot find the external libraries. For example, I receive the following error when running the application:
java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
The "missing" class is included in one of the jars but for some reason these jars are not accessible to Web Dynpro at runtime.
Any help you can provide on this problem is very much appreciated.
Thanks in advance!
Jason

I created the JAR with the following class (structure):
com.sap.tc.webdynpro.tests.utils.TableSorter.class
I have followed the steps that was suggested in the forum:
==========================================================
1) creating an Extneral library DC
2) import the JAR "com.sap.tc.webdynpro.tests.util.jar" to the libraries folder of the External Library DC project
3) Right-click on the JAR imported to the project and add them to the public part.
This DC is now ready to be used as a build-time reference that will allow CBS to build the "main" Web Dynpro application that will use the external libraries. Next, we have to create a new Web Dynpro DC to hold the class files here are the steps:
1) Create a new Web Dynpro DC
2) Create a new public part, selecting the "Can be packaged into other build results" option
3) Rename the JARs as Zip files and extrct the full content (folders and class files) to your root folder
4) Import the folders and files to the src/packages folder
5) Expand the public part node that was created and select the "Entities" node, right-click it and choose Edit
6) In the Entity Type list select the "Folder" option then in the selected entities tree pick each of the folders that you imported in step 5 (above)
7) Now do a DC build and a DC deploy of the project
Then check-in, activate, and release any activities you have associated with creating these two projects. In the DC perspective, refresh the Active DCs and Inactive DCs to ensure that both new DCs appear in the Active list. Now we have to setup the references to these DCs in our main Web Dynpro application. To do this, follow these steps:
1) Open the Web Dynpro perspective and right click the Used DCs node then choose "Add Used DC.."
2) Pick the public part of the External Library DC that we created (first) and set it to have a Build Time dependency
3) Again, right click the Used DCs node and choose "Add Used DC.." then choose the public part of the Web Dynpro DC that we created and give it a Run Time dependecy (weak) and click finish.
4) Now, due to what I think is a bug. You must right click on the Web Dynpro "used DC" that you just added in the previous step, and set the run time dependency again (it seems to revert to the default values for some reason)
5) Now do a DC build and a DC deploy on the "main" web dynpro application.
6) Check-in, activate, and release any activities associated with adding these references and then others on your team may use the classes in the external libraries within the Web Dynpro project.
However, when I executed, the following exception occurred:
===========================================================
Error stacktrace:
java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/tests/utils/TableSorter
at br.com.embraer.materiais.zdplmm001.view.Zdplmm001_0500View.wdDoModifyView(Zdplmm001_0500View.java:138)
What's missing????

Hi Valery,
thanks for this great idea. Indeed, there is no channel set up to communicate feedback/suggestions/questions to Web Dynpro tutorials or articles in a standardized way.
WebLogs can be commented on the WebLog page itself and they are announced in a special ;\ New Web Dynpro Weblogs which can be opened via the <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/49f2ea90-0201-0010-ce8e-de18b94aee2d">Web Dynpro Feature2Sample Matrix</a>. Actually the section 'Further Information' lists all related articles, WebLogs etc. These links are regularly updated so that the Sample Description Pages helps to keep all links to valuable information in a central place.
The 'Sample Description Page' should additionally comprise a section 'Discussion' with a link to the above 'Article Comment Thread' in the Web Dynpro forum. The reader downloads the material from the sample description page and also finds a link to the related 'Article Comment Thread' there.
For all new articles (which are combined with a related 'Article Comment Thread') the Further Information links could point to the 'Article Comment Thread' (which then itself links to the article) but not directly to the article resource. The reader can then also have look at the existing comments to the related resource. As an alternative the article PDF itself should have a permanent link to the 'Article Comment Thread' in the Web Dynpro Forum.
Please post your comments on this idea.

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

Sequencing Problem in Web Dynpro ABAP

Hi Web Dynpro (ABAP) Guru's,
Can anyone tell me how to read a parameter from the WDA url in my view? The situation is like this: My WDA is being rendered in the Portal EP 6.0 as an iView. When my WDA is called the portal also appends in the URL the plant number. I want to grab that plant number and use it in my view to show some default data.
As per other weblogs/forum posts I defined a parameter "PLANT_NO" in the "Default" startup plug of my Main window. I'm using the Get_Data method to read this parameter in the plug. I'm able to read the URL parameter here and so far it is good. Read below for the problem..
If I understand the order of operations correctly, doesn't the views get created, then the default plug code is run, then the views are placed on the window and then shown to the user. Since my views are created before my default plug is run I DO NOT get the URL parameter value in the WDDOINIT of my view. When I debug the application, the WDDOINIT of the embedded view gets called before the Default startup plug. Am I missing something here?
If someone can tell how to read the URL parameter in the WDDOINIT (instead of Default Startup) of the view I could default in the data I want to display. OR any other suggestions to get past this problem would be appreciated.
Does this make any sense and does anybody have an idea of where I could find some info about how to do this?
Thanks much for your help. Points will be awarded.

Thanks Klaus for the response.
I don't want to read the parameter from the default plug, but need to access the URL parameter and display default data in my view. Let me explain the scenario:
My Web dynpro application is called from the Portal. The Plant number is passed in the URL as:
http://...../sap/bc/../../<Web Dynpro Application name>?PLANT_NO=0012
I want to show Material Stock values in the view for Plant "0012". To access this value I've defined a parameter with same name (PLANT_NO) in the default startup plug of my main window. I get access to the URL parameter through this plug parameter.
I have only ONE view embedded in this window where the Stock values are selected from table MARD for the specified plant. I want to get the plant value from URL in my WDDOINIT method to make this selection from database. I'm then binding the results to the view table UI element. My problem is that the URL parameter is read in the Default plug, but the data selection and view binding happens before in the WDDOINIT method where I don't know the plant.
Again, I don't want to read the plug parameter, but I want to get the URL parameter (PLANT_NO) and then render the view based on the data selected for this parameter. Please let me know how this can be achieved by reading the URL parameter in WDDOINIT method (Constructor) so that it can be used subsequently in the application.
Thanks for your help and looking for a resolution.....

Generation of document no in web dynpro

Dear All,
I have requiriment where i have to generate document no when material ,plant , storage location ,deliverydate
etc are entered into table fields and save button is clicked in a web dynpro application. Then the above details must be saved into a custom table along with the generated document number.
Thanks and Regards,

hi,
Create a number range object in SNRo T-Code ans Use NUMBER_GET_NEXT using the number range.
Use this number for saving the data.
