Using an exsiting BI query in Web Dynpro

I am interested in using an existing BI query in Web Dynpro. The NetWeaver Developer Studio 7.0.06 contains some good documentation about how to create and execute an MDX statement on a BI cube. However, I find this approach both complicated and impractical and I'd like to maintain my queries solely in the BI Query Designer. I cannot find any documentation on importing an existing BI Query and using it within Web Dynpro. I find this odd since the BI Java SDK Developers Guide specifically recommends this. Is it the case that a BI Query can be treated as a cube within the Java code and found through IBIOlap? Further, I cannot find any examples that show me how to construct a graph from the data as portrayed in the "BI Java SDK: A Business Scenario" portion of the NetWeaver documentation, or, place the result set on a table that can be used in an IView. Also, all of the examples in the documentation are Servlet based. I'm looking to create IViews for Portal deployment. In summary, I'd like to create a table and graph combination, based on a BI Query, that I can deploy to the Portal using Web Dynpro. Can you provide some insight on these questions and point me to some concrete examples of how to do these things?

Vitaliano,
You make a very good point. And it is probably the way that we will go. However, my task is to evaluate Web Dynpro and Visual Composer for our needs. Especially since the graphing capabilities in Web App Designer are limited for our needs. We will, at some point, have a need to combine warehoused information in BI with real-time data in R/3. I'm anticipating that this is where Web Dynpro will be useful for us. Therefore, my questions as stated regarding Web Dynpro. I just find it strange that none of the SAP documentation elaborates on the topics that I am concerned with, even though tantalizing capability summaries are dangled throughout.
Thank you.

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

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'
Steps i followed are as below:
1. Created Adaptive Web Service Model for this i select WSDL source as "Local File System or URL"
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.

Using RepositoryFrameworkWS in web dynpro Java 7.1 CE

Hi All,
I am new to KM, and i have a requirement to create a document in KM of 7.0 from a web dynpro java application developed in NWDS 7.1 CE. I know i can use RepositoryFrameworkWS web service to achive this. But I need some help to start with it.
So it would be of great help, if i am provided with some Documents, Code snippets or links regarding this.
Thanks & Regards,
Vishweshwara P.K.M.

Hi Mukhuti,
I had tried setting ParentCollectionRid as "\documents" and when I execute the application i get the exception stating "Exception on execution of web service with WSDL URL 'http://<URL>' with operation 'createDocument' in interface 'RepositoryFrameworkWSVi_Document'".
Also is it mandatory to set UserId and password to create new document, if yes is it an admin Id.
Thanks & Regards,

Caching in Web Dynpro Java

Hi Experts,
I am trying to develop a web dynpro for java application based on RFC model.
I am using an RFC that brings the Countries and States from the R/3 and will be used as dropdowns in the views controllers.
The question is:
I would like to cache the Countries and States in my web dynpro application. The idea is not to execute the model everytime. The model should be executed only once. I would like to store these countries and states in a local java dictionary or etc. and use them for UI element designing.
Is there any way to do this in Web Dynpro Java? I would like to follow a better approach to avoid performance problems.
I do not want to follow this approach: executing the model in the wdInit method of the controller. Executing this model in this method also causes performance problems. Because the model is brining approx 1540 records from R/3.
Please advice.

Hi All,
Thank you for the suggestions.
I am a beginer in wd java. i am starting with amit's suggestion.
Step 1: Execute RFC to fetch data preferably use doInt method for it.
Should I execute the method in wdInit of the view controller/component controller?
I defined a method "executePMPReadBAPI" in component controller.
public void executePMPReadBAPI( )
    //@@begin executePMPReadBAPI()
   try{
        wdContext.currentPMPDoctorReadElement().modelObject().execute();
        }catch (Exception e){
        logger.errorT("Error in executing PMP Read BAPI");
wdInit of View controller:
          IWDAttributeInfo countryInfo =
               wdContext.getNodeInfo().getAttribute(
                    wdContext.currentContextElement().COUNTRY);
          ISimpleTypeModifiable countryType =
               countryInfo.getModifiableSimpleType();
          IModifiableSimpleValueSet countryValueSet =
               countryType.getSVServices().getModifiableSimpleValueSet();
          for (int i = 0; i < wdContext.nodeCountries().size(); i++) {
               IWDNodeElement CountryNode =
                    wdContext.nodeCountries().getElementAt(i);
               String countryKey = (String) CountryNode.getAttributeValue("Land1");
               String countryText =
                    (String) CountryNode.getAttributeValue("Landx");
               countryValueSet.put(countryKey, countryText);
This coding is working, I am able to populate the dropdowns. The problem is the application is slow.
I am guessing this much coding is not necessary in the view conroller's wdInit method.
Why the binding approach like mentioned below is not working (model>Conroller>View)? How should I execute the RFC in the wdInit of the component controller? Is this possible?
wdInit of Component Controller: Below coding and proper binding is not sufficient to populate dropdowns? Please advice.
     Zhr_Ess_Address_Input ReadInput = new Zhr_Ess_Address_Input();
          wdContext.nodeZhr_Ess_Address_Input().bind(ReadInput);
          try {
               wdContext
                    .currentZhr_Ess_Address_InputElement()
                    .modelObject()
                    .execute();
               wdContext.nodeOutput().invalidate();
          } catch (Exception e) {
               logger.errorT("Error Reading the BAPI");

Synchronization in Web Dynpro JAVA

Hi All,
I have a Web Dynpro JAVA application, for which an iView has been created and is assigned to a role. Now I have the below requirement,
If two users tries to access this application at the same time then the second user has to get a message stating that "A user is already accessing this application please try later". Basically the thread concept. Is it possible to achieve this in Web Dynpro JAVA. If yes please provide me some pointers on how to achieve this.
Thanks & Regards,
Vishweshwara

Hi Vishweshwara,
Create the Custum table with UserID fields.
Create the RFC with UserID fields as input parameters and result field as export parameter.
Write the logic in RFC if Custum table contains any value in UserID Field then return error message like " This application is already using by <UserID>"
else
stor the values UserID and LoginStatus(which you are sending from Webdynpr java app) in custom table and return success message.
Create webdynpro java component and create two iview called main and info view
import the RFC in webdynpro java app and do the binding from model to component controller and component controller to view controller of main.
Write the following code in wdDoInit() method of main view to get the login userid and sending that to RFC.
String userID = null;
IWDClientUser clientUser = WDClientUser.getCurrentUser();
IUser User = clientUser.getSAPUser();
if (User != null)
try
IUserAccount[] acct = User.getUserAccounts();
if(acct[0] != null)
userID = acct[0].getLogonUid();
wdContext.current<RFCNodeName>Element().setUserID(userID);
catch(UMException e)
//Raise some error msg according to your scenario.
//code for calling the RFC
wdThis.wdGet<ComponentControllerName>().execute();
String msg = wdContext.current<OutputNodeName>Element().getResult();
if(msg != null && msg.lenght() !=0)
if(msg.equalsIgnoreCase("This application is already using by <UserID>")
wdThis.wdFirPlug<PlugName>();// code for naivigate from main view to info view
the navigation between main view to info view needs to defined in navigation moduler area.
if you foolow the above specified way u can achive your requerment.
Revert back if you any quaries.
Thanks & Regards,

Web Service Consumption in Web Dynpro Java

Hi,
I'm using NetWeaver 2004s for Java. I have generated a Web Service out of a BAPI. I use that Web Service in a Web Dynpro Java Application as Model. Model generation works fine. But when I call the Web Service during execution of the corresponding Web Dynpro Application, I get the following Exception:
"java.rmi.RemoteException: Service call exception; nested exception is: java.lang.Exception: Call to returned http code 500 with unacceptable content type (text/html; charset=iso-8859-1). <HTML> <HEAD> <TITLE>Unknown Host</TITLE> </HEAD> <BODY BGCOLOR="white" FGCOLOR="black"> <H1>Unknown Host</H1> <HR> <FONT FACE="Helvetica,Arial"><B> Description: Unable to locate the server named "<EM>us0308.wdf.sap.corp</EM>" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again. </B></FONT> <HR> </BODY>"
Testing the Web Service via transaction WSADMIN works fine. Can anybody give me an advise how to solve that problem?
Thanks in advance!
Regards,
Frank

Had Exactly same problem with authorization issues on the server hosting the webservices.
Create a CPIC user Id on the server hosting the webservice. The user id should have authorization to execute the webservice.
Create a webservice destination in VA for the said webservice using the user id
1. Log on to the J2EE Engine as an administrator using the Visual Administrator.
2. Expand -> Server ->Services.
3. Select the Destinations service.
4. Under Destinations, select HTTP and choose New
You need to create two destinations one for matadata and another for execution data.
Use the destinations while creating the WS model in NWDS.
if you have issues importing the model using the URL, you can create the model using the WSDL and use the WS Destinations to execute it.
I am following the same approach after i had faced similar issues with webservices on PI7.1 and Portal 7.0
About the option to use _setusername, _set...., not all webservices come with the _set methods.
and moreover if you do that, it would be more of hardcoding in the code, which should be avoided.

Nitin

About Flash Islands In Web Dynpro Java

Hi All,
We developed a sample Web Dynpro Java application with Flash Islands. It executed fine. We used the Flex 2.0.1 Hotfix 3 Compiler. But now we have a requirement to use Flex 3.2 complier. But if we use SWF files in Web Dynpro, comipled with Flex 3.0 complier, It is not rendering the UI components. How can I resolve this problem. In some thread, I saw this problem is resolved in latest patch of CE 7.1 EHP1. Is it?. If so what is that patch and from where I can download this patch?
Thanks,

Database operation with web dynpro java

Hi,
Our portal installed on MaxDB database.We need to develop web dynpro java application has some database opeartions (insert,update, delete, select) on MaxDB database.
1- Is there a blog or sample how can it be done over MaxDB?
2- Is there exploring tool for MaxDB to create tables?
Thanks.

hi,
point 1, it is just pure java programing
you can go with this:
ResultSet result = null;
try
InitialContext initialcontext = new InitialContext();
DataSource datasource = (DataSource)initialcontext.lookup("jdbc/<DataSourceName>");
Connection connection = datasource.getConnection();
Statement statement = connection.createStatement();
result = statement.executeQuery( <Query>);
connection.close();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
2. maxdb has standard client you can use to manage the database

Create a Table Dynamically in WEB Dynpro Java with diferent type of column

Hi everyone, I have a question if is possible to create a table dynamically in Web Dynpro Java?, depending of the RFC consults create the rows dynamically, ,this table must have diferent type of columns, for example link column (when the user click this link execute an action and show a adobe interactive form in another view), image column (show an image depending of the information)
Thank you everyone
Atte Israel

Hello,Israel.
Yes , it is possible through dynamic programming in wdModify of the View.
You can do this ,for example, using cell variants.
IWDTable tab = (IWDTable) view.getElement("TABLE_NAME");
IWDTableStandardCell cellV= (IWDTableStandardCell) view.createElement(IWDTableStandardCell.class,"TableStandardCell"+i);
cellV.setVariantKey("NotEditableVariant");
cellV.setCellDesign((WDTableCellDesign)wdContext.nodeTableDaysTitle().currentTableDaysTitleElement().getAttributeValue("CellDesign"+i));
IWDTextView textViewi= (IWDTextView) view.createElement(IWDTextView.class,"TextView"+i); // -- here you control the type of the object that is displayed in the cell
textViewi.bindText(dayAttrib);
cellV.setEditor(textViewi);
tabColumn.addCellVariant(cellV);
tab.addGroupedColumn(tabColumn,tab.numberOfGroupedColumns());
Using this code you can control even specific cells in the table and not only columns.
Hope this helps you,
Constantine

Kill the RFC connection as soon as the call is completed in Web Dynpro JAVA

Hi Experts,
Please guide us how to kill the RFC Connection from web dynpro java as soon as the execution is completed.The FM connection (Adaptive RFC) isnt getting closed in IS-U side. Please guide us how to close them explicitly.
We are getting the following error
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300)

hi suvankar ,
wdContext.current<Modelname>_InputElement().modelObject().modelInstance().disconnectIfAlive();
use this option after executing your rfc, it will remove the connection to the r/3.
adn this
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300) -- is occuring because the pool size defined the jco destination is not sufficient, ask your basis team to increase the pool size.

Problem of refreshing a tree in web dynpro java

hi all,
I'm facing a problem for refreshing a tree in web dynpro java for SAP HR.
I created a viewset with 2 cells( 1 view for each).
In the 1st view I created a droplistbyindex to select the unit ID and in the 2nd view ( defaut=false) I called a method to populate my tree according to my selection in the 1st view ( method called in wdInit).
When I make the first selection everything is ok.
But when I select another unit ID, the tree is not changed and I know the context is well changed according to my selection.
So I think the method is executed only the first the view is called.
In this case, how can I refresh my tree on real-time?
Thanks for your help

May be u can write the code wdDoModify instead.

How to display smartform as PDF in web dynpro java

Hi,
Where can I find sample program to display smartform as PDF in web dynpro java.
Thanks.
Regards,
Henry

1. Create a smart form in the R/3 side
2. Now create a function module with the corresponding export parameter:
3. Make sure that the function module is marked remote enabled.
4. In NWDS create an Adaptive RFC model which points to the FM created in R/3 under the webdynpro application
5. Now create an application and view inside it to display the PDF and Insert a frame inside the view
6. Create a value node and an attribute say url of type string inside that node and bind it to the source
7. In the doInit() method place the following code
>    ZTest_Pdf_1_Input input = new ZTest_Pdf_Input();
>    wdContext.nodeZTest_Pdf_Input().bind(input);
>    try {
>            wdContext.currentZTest_Pdf_InputElement().modelObject().execute();
>            }
> catch (Exception e) {
>                        e.printStackTrace();
>            }
> wdContext.currentInternalElement().setUrl(convert(wdContext.currentOutputElement().getBin_File()));
Inside that view create a method to convert the string to url so that it can be passed as a string to the setUrl method of the currentContextElement() , say convet(byte[] doc_content) which return a string.
Inside that methos write the following code,
