How to passing lowercase values to RFC/BAPI using webdynpro for JAVA

Hi Exerts,
When we sending values to RFC/BAPI through webdynpro (JAVA), the values are sent in capital (uppercase) letters to ECC.
So if we fill xxxx, it is send like XXXX. Why? and how to avoid this?
Thanks in advance,
Joeri

Hi,
There could be two possibility if you are storing this value in ABAP table.
1. You are entering value in UPPERCASE in your webdynpro application.
2. The data stored in ABAP table, converts value in small to upper case.
1. Can you tell me how you are passing this value, is user entering value in some input field which is binded to some context and this value are you passing to RFC/BAPI...???
Or else before passing value to RFC/BAPI you can use toLowerCase string function and the npass this value to RFC/BAPI
e.g String name = wdContext().currentContextelement().getName().toLowercase();
Now pass this name to RFC/BAPI is should go as lowercase only..
This is from webdynpro java side..
2. If you are storing this value in ABAP table, check the domain/type of variable in ABAP table for which you are storing the value. Ask ABAPper, so that this value are stored in small case letter.
There is one tick in domain which you need to remove so that it stores in lower case. I dont have exact information but you can consult this with ABAPer.
Hope this information helps guy ..!!!!

Accessing knowledge management documents using webdynpro for java

Dear all,
iam having some documnets in KNLOWLEDGE MANAGEMENT documents folder in portal using webdynpro for java clicking on a link means perner(employee no) i should get that perpicular employee number documents.
examples documents are stored like this in knowledege management folder 20016319.pdf , 20016397.pdf , 20016398.
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!!

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.

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.

How can I read cookies in WebDynPro for Java

Hi,
in WebDynPro for Java I found a possibility to to get a "request-object" like the standard "HttpServletRequest-object"
IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
IWDRequest request = protocolAdapter.getRequestObject();
debugEnabled = (request.getParameter("Debug") != null);
With this request-object I can read request-prameters but I couldn't find a possibility to get cookies from the request.
There is no method like the "getCookies().method" in the HTTPServletRequest-Interface:-((
Has anybody an idea, how I can read cookies in WebDynPro for Java ?
Regards
Steffen

Hi,
This is the latest update I could look for regarding cookies and webdynpro.
Panic - WebContextAdapter is depracted - no more cookies now?

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");

File open using Webdynpro for java

Hi,
I have a file "SAP.JPEG" in remote machine location "
SAP\NetWeaver\WebDynpro".
In my webdynpro application...I have a button and the action "OpenFile"...
My question is on click of the button, how can I open the file "SAP.JPEG".
Please advice me how to proceed with this.
Rgds,
Patana

Hi,
it is possible to access the file from the remote system using webdynpro java. your requirements is quite possible.
the prerequisites are:
the SAP WebAS Server and the remote system are in the same network, and the folder (in your case "SAP") is shared folder with access permissions.
let us assume your remote system name is remSys09.
add an ui element image in the layout. and create an attribute named "image " bind it to the property source
use this below code to show the image.
try {
          File f =new File("////remSys09//SAP//NetWeaver//WebDynpro//SAP.JPEG");
          BufferedInputStream bis= new BufferedInputStream(new FileInputStream(f));
          byte[] image = new byte[bis.available()];
          bis.read(image);
          IWDWebResource webResource = WDWebResource.getWebResource(
          image,
          WDWebResourceType.JPG_IMAGE);
          wdContext.currentContextElement().setImage(webResource.getURL());
     } catch (Exception e) {
          // TODO Auto-generated catch block
