Advantages and dis advantages of web dynpro java

Hi Guys,
May i know what are the advantages and dis advantages of web dynpro java?
Regards,
Madhu

Hi Madhu,
Web Dynpro (WD) is a proprietary web application user interface technology developed by SAP AG and exists in a Java (Web Dynpro for Java, WDJ or WD4J) and an ABAP (Web Dynpro ABAP[1] , WDA) flavor. Both have in general the same functionality, but usually one flavor is improved after the other, so temporary one flavor is more advanced than the other. Hence, the decision for one of the two flavors shall be based on organizational and business circumstances, but not on functionality.
WD follows an adapted MVC pattern and a model driven development approach ("minimize coding, maximize design") with a large number of dedicated hooks in generated code to place custom coding. It is intended for business applications that shall follow standardized UI principles, connect to backend systems and be scalable.
Main advantages of Web Dynpro over other technologies
typed access for design time checks, e.g. navigation links and messages are accessed via types instead of string keys like in JSF
diverse services for backend access, like aRFC, JEE and Web Service data models
integration with SAP Interactive Forms by Adobe, which are interactive PDF forms, during design (same IDE) and run time (data sharing)
integration with business process management and business rules management (since NetWeaver CE 7.1 EHP 1)
designed to support development big scale applications by adding multiple grouping layers on top of Java packages (DCs, SCs, products)
runs on different clients e.g. web browser, mobile device, widget engine
comes with a big collection of UI elements providing a wealth of functionality and only have to be configured but not programmed
Main disadvantages
proprietary, running only on SAP servers
less flexible due to support for multiple clients (i.e. custom html is not possible). To reduce the limitations, several measures have been taken. For example, WD supports so-called "islands" for e.g. flash applications that enrich the Web Dynpro UI element collection by rich UI elements. This disadvantage doesn't seem so serious but in fact basic features that user expect to receive cannot be implemented (e.g. coloured rows in table, colours in general, advanced aligning of simple UI elements (due to nonexistence of more complicated ones), selecting multiple rows in tree-like tables (this is due to preserving basic concept of WD) and many more). Having the flash feature means that developer completely avoids WD UI (And thus cannot use other features).
rendering speed in browser for larger tables (>1000 rows)
The designtime and runtime environment is part of SAP NetWeaver 7.0[2] (also known as Netweaver 2004s) and following releases.
The name comes after the original Dynpro library, whose name meant "Dynamic Program".

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.
regards,
Sharam

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
6) Full integration in the reliable ABAP development environment
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/77/3545415ea6f523e10000000a155106/frameset.htm
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.
for more see:
http://help.sap.com/saphelp_nw2004s/helpdata/en/15/0d4f21c17c8044af4868130e9fea07/content.htm
The concept of Web Dynpro ABAP is identical with Web Dynpro Java and offers more or less the same functions

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?
Regards,
Thomas
PS: The 7.0 procedure, which can be found in various posts, doesn't seem to work any more for CE 711.

Date Column not getting sorted in a table in web Dynpro Java

Hi All,
I am facing an issue while sorting the date column in a table in my web dynpro java application.
When the date is displayed in the sql format in tha table, I am able to sort the date column successfully but when we convert the date field from sql format to util format in our table and then sort it does not work.
Kindly let us know the steps to be followed in this case to sort the date column of a table in Simple Date format as we do not want date in the sql format to be displayed.
Thanks & Regards,
Anurag

Hi,
You might want to check whether both your browser's language settings are identical. The browser language could also determine the date format.
As a workaround, you could add an extra attribute to your context, and set the calculated property to 'true'.
In your table, add a new column and bind to this new attribute, and hide your original date column
If you sort using the date column that's hidden now, you could use the calculated field to fixed-format your date the way you prefer (by using the SimpleDateFormatter class for instance)
Cheers,
Robin

Hi Amit,

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)

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
Regards
Piyush

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks

Web Dynpro Java - Light Portal Desktop

Hi Guys... I have a web dynpro java application that I want to display on a Light Portal Desktop, but when I display the iview... it gets cut. I mean I can see only part of my application and there is also a right scroll bar... It looks like the height size of the iview is set to "FIXED" but it's not. I Actually modifed all values for size even on the Light Framework Page used...to FULL_SCREEN. I don't know what's wrong. If I display the same iview using a Default Framework Page it looks fine... I'm using SAP EP 7.00 SP 16.
Is there any restriction for using Web Dynpro iviews for Light Porta Desktops?
Thank you.
David

David,
Webdynpro content is considered heavy and I dont think we can use it in LPD.
Update:
Note 916545 - Central Note for External-Facing Portal (NW 7.0)

" APPLICATION NOT FOUND" while deploying Web dynpro java Application

Hi, I am getting a message that "application not found " While deploying the web dynpro java application .......... please give me a solution for this .

Hi Ram,
This error comes generally when your webdynpro project does not have an application. To create an application in your webdynpro project follow the underlying steps:
<Project>->WebDynpro->Applications ---> right click and create New Application.
Follow the steps to create the application.
Now if you create archive and deploy, it will not give you the error again.

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
 //@@begin onActionUpload(ServerEvent)
 IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
 IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
 IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
 getModifiableSimpleType();
 IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
 String fname = binaryType.getFileName();
 wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
 try {
 wdComponentAPI.getMessageManager().reportSuccess("Successful"); // Statement 2
 InputStream in = new FileInputStream(fname);
 HSSFWorkbook wb = new HSSFWorkbook(in);
 wdComponentAPI.getMessageManager().reportSuccess("Successful"); //Statement 3
 int sheetsNo = wb.getNumberOfSheets();
 for (int i=0;i<sheetsNo;i++) {
 HSSFSheet sheet = wb.getSheetAt(i);
 Iterator rowsNo = sheet.rowIterator();
 while(rowsNo.hasNext()) {
 HSSFRow rows = (HSSFRow)rowsNo.next();
 Iterator colsNo = rows.cellIterator();
 while(colsNo.hasNext()) {
 HSSFCell cell = (HSSFCell)colsNo.next();
 wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
 "successfully");
 if(cell.getCellType()==1) {
 wdComponentAPI.getMessageManager().reportSuccess("00000"+
 cell.getStringCellValue());
 else if(cell.getCellType()==0) {
 String str=""+cell.getNumericCellValue();
 wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
 catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
 //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

Consuming External Web Services in Web Dynpro Java

Hi All,
I an trying to consume external web service in Web dynpro java using Adaptive Web Service Model.
But getting below mentioned error while executing the web service
Exception on execution of web service with WSDL URL 'D:\Web Service Project\CurrencyConvertor.asmx.xml' with operation 'ConversionRate' in interface 'CurrencyConvertorSoap'

In next step i select No logical destination radio button and click on next
In next step, browse the WSDL file and successfully import the WSDL file.
2. After successfully importing the WSDL file i wrote below code in Init method:
WebModel modelweb = new WebModel();
Request_ConversionRate reqConversion = new Request_ConversionRate(modelweb);
ConversionRate conversion= new ConversionRate(modelweb);
reqConversion.setConversionRate(conversion);
wdContext.nodeRequest_ConversionRate().bind(reqConversion);
3.After that execute the model - code is given below :
    IWDMessageManager manager = wdComponentAPI.getMessageManager();
    try
      wdContext.currentRequest_ConversionRateElement().modelObject().execute();
      wdContext.nodeResponse().invalidate();
      wdContext.nodeConversionRateResponse().invalidate();
    catch(Exception e)
      manager.reportException(e.getMessage(), false);
Please let me know how to resolve this.
Thanks

Hi,
You need to use destinations for metadata and modeldata.
Configure those destination in Visula admin.
you can refer to following link.

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...
Regards,
Saleem Mohammad.
