How to access(connect) BI Data in webdynpro for java applications

Hi ,
is there any way to access and display the BI data in portal using webdynpro for java applications like we did in Visual composer.
if not how to integrate the BI data in webdynpro applications ?
Regards,
Govindu

Hi,
Yes there are ways to do it. But may your scenario and the scenario for which I have done may differ.
You can use openhub to get the data in a flat file and then read it into weddynpro through a java service OR
You can use DBlink(which i have done).
Please refer the link below:
[Link|Data from BW to Oracle.;
This I have done in NW04s. Not sure whether a better solution is available in the newer release.
Hope it helps.

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
<b>I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?</b>
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

how to access those employee using webdynpro for java for perticular employee number if i want 20016319
Send me the code for above requirement and where i have to wrirte that code exactly
Regards

Dear Kishore,
To get the Employee ID you have to create a Adaptive RFC Model (call BAPI) which will return you the employee pernr, for this
1. Create a model using : BAPI_EMPLOYEE_GETDATA
2. Get User ID using the code
public java.lang.String getUserID( )
    //@@begin getUserID()
     String userID = new String();
          try
                // getting Logged in userid
               IWDClientUser myUser = WDClientUser.getCurrentUser();
               userID = myUser.toString().substring(19).trim();
               StringTokenizer filterdUID = new StringTokenizer(userID,")");
               userID = filterdUID.nextToken();
          catch (WDUMException e)
               e.printStackTrace();
               return userID;
    //@@end
3. Execute the BAPI
public java.lang.String getEmployeeID( java.lang.String userID )
    //@@begin getEmployeeID()
     String employeeID = new String();
          Bapi_Employee_Getdata_Input employeeData = new Bapi_Employee_Getdata_Input();
          Bapi_Employee_Getdata_Output outData = new Bapi_Employee_Getdata_Output();
          Bapip0105B comm = new Bapip0105B();
          com.sap.aii.proxy.framework.core.AbstractList list = new Bapip0105B.Bapip0105B_List();
          list.add(comm);
          employeeData.setUserid(userID);
          Calendar cal = Calendar.getInstance(Locale.UK);
          Date date = new Date(cal.getTimeInMillis());
          employeeData.setDate(date);
          employeeData.setAuthority_Check("");
          employeeData.setCommunication(list);
          outData.addCommunication(comm);
          wdContext.nodeBapi_Employee_Getdata_Input().bind(employeeData);
          wdContext.nodeOutput_BAPI().bind(outData);
        try
               wdContext.nodeBapi_Employee_Getdata_Input().currentBapi_Employee_Getdata_InputElement().modelObject().execute();
               wdContext.nodeOutput_BAPI().invalidate();
        catch (WDDynamicRFCExecuteException e) {printMsg("Failed to Obtain Employee Data");
             e.printStackTrace();
        employeeID = wdContext.nodeBapi_Employee_Getdata_Input().nodeOutput_BAPI().nodeOrg_Assignment().currentOrg_AssignmentElement().getPerno();
        return employeeID;
    //@@end
Hope it Helps!!

Basic TableUI element to Reset Data in WEbDynPro For Java

Hi Experts,
I am new to webdynPro for java . Can anybody plz help me out.
i wrote the following code to retrieve data from DB. which is working very much fine.
public void
onActionGetRecords(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
while(rs.next()){
tabstrip.comp.wdp.IPrivateSearchEmployee.IEmpDetailsElement elt= wdContext.nodeEmpDetails().createEmpDetailsElement();
                      elt.setSNo(rs.getString(1));
                      elt.setName(rs.getString(2));
                      elt.setPlatform(rs.getString(3));
                      elt.setPhNo(rs.getString(4));
                      elt.setCity(rs.getString(5));
                      wdContext.nodeEmpDetails().addElement(elt);
Now my problem is when i call this action its adding the rows to Table UI elements.
Can anybody please help
how to reset values in TableUI element when i click on reset button OR when i call onActionGetRecords(-----) methods,
Please help me .....
thanks and Regards,
Shashikiran

hi,
if you want the data to be erased(reset)
in your code
tabstrip.comp.wdp.IPrivateSearchEmployee.IEmpDetailsElement elt= wdContext.nodeEmpDetails().createEmpDetailsElement();
elt.setName("");
elt.setPlatform("");
elt.setCity("");
wdContext.nodeEmpDetails().addElement(elt);
by this way you can reset all the values present in the table
and can you make it more clear for on action getrecords
or you acn use the remove method to remove the table element
wdContext.nodeXXX().removeElement();
thanks and regards

PDF generation from Webdynpro for java application

Hi all,
I have a scenario in which a PDF has to be generated from the datils present in a table in the same view, on click of a button. I have found many solutions for generating interactive forms but I need to generate it from the code directly. I have also found an application for generating an excel sheet from the table data but it is not working with PDF.
So anybody suggest me how to do it or please refer any applications that have been done.
Thanks in advance.

Hi marco,
Sorry for the late reply.
I have got an application to generate an excel file and i will paste that code here for your reference.
    byte[] excelXMLFile;
    IWDCachedWebResource cachedExcelResource = null;
    String fileName = dataNode.getNodeInfo().getName() + ".xls";
    try {
      // create Excel 2003 XML data as a byte array for the given context node, attributes and headers
      excelXMLFile = this.toExcel(dataNode, columnInfos).getBytes("UTF-8");
      // create a cached Web Dynpro XLS Resource for the given byte array and filename
      cachedExcelResource = this.getCachedWebResource(excelXMLFile, fileName, WDWebResourceType.XLS);
      // Store URL and filename of cached excel resource in context.
      if (cachedExcelResource != null) {
        wdContext.currentContextElement().setExcelFileURL(cachedExcelResource.getURL());
        wdContext.currentContextElement().setExcelFileName(cachedExcelResource.getResourceName());
        // Open popup window with a link to the cached excel file web resource.
        this.openExcelLinkPopup();
      } else {
        wdComponentAPI.getMessageManager().reportException("Failed to create Excel file from table!", true);
    } catch (UnsupportedEncodingException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
    } catch (WDURLException e) {
      wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
In the above code "excelXMLFile" is a byte array in which the data that has to be appended to the pdf (in xml format) is present.
the toExcel method is used to convert the data in the table(i.e., the data that gets populated in the nodes of the view) in to XML format.
My Problem is when i change the filename to .pdf extension and the WDWebResourceType.XLS to WDWebResourceType.PDF and execute the application the Acrobat reader is getting opened but it says
"unsupported file type or the file has been damaged" .
I mean i am unable to put data into the file.
So, please help me in this regard.

Hi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.
