i am using jdk 1.6.22 and IBM WebSphere
when i use poi-3.6-20091214.jar and poi-ooxml-3.6-20091214.jar to read .xlsx file. but i am getting following errors
The project was not built since its classpath is incomplete. Cannot find the class
file for java.lang.Iterable. Fix the classpath then try rebuilding this project.
This compilation unit indirectly references the missing type java.lang.Iterable

How to read the excel file using webdynpro abap?

Hi,
how to read and modify excel file using webdynpro abap?
Regards,
Pavani

For reading excel file follow the steps :
1. Use a File upload UI element and bind it with xstring.
2. Now your excel will be uploaded and stored in Xstring.
3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
4. Now split the string at new line so as to make an internal table .
Ex . SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE it_table.
here it_table is type table of string.
5.now loop at the internal table and separate the content of this table separated by tab.
Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
it_new type string_table.
6. For more info , refer this thread :

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.

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!!

Hi,
If you want to upload the data using EXCEL file use the function module ALSM_EXCEL_TO_INTERNAL_TABLE.
Examples for ALSM_EXCEL_TO_INTERNAL_TABLE.

Uploading Excel file using 'ALSM_EXCEL_TO_INTERNAL_TABLE'

Hi,
I am uploading excel file into an internal table using 'ALSM_EXCEL_TO_INTERNAL_TABLE' FM.
but I'm getting a popup with the message
'There is a large amount of the information on the clipboard. Do you want to be able to paste this information into another programme later.' and there are three buttons in the popup 'YES', 'CANCEL' and 'NO'. but for any choice there is no data in the internal table.
the progrsm is working in other systems but giving problem in customer laptop, can you please tell me is there any settings need to set for EXCEL or SAP.
system details are as below
OS: windows 7
MS-Office - 2007

Looks like there was an intention to clear the clipboard in the code, but this does not seem to work.
I copied the function module to my own version and added the following code, which seems to work :
* clear clipboard
refresh excel_tab.
call method cl_gui_frontend_services=>clipboard_export

Problem while uploading excel file to server

Hello,
I have created an excel file using OLE and saved it to local desktop. Then I use GUI_UPLOAD to upload the excel into SAP and attach it to mail. but while using Function GUI_UPLOAD I am getting dump for CNTL_ERROR.
If I skip the process of excel creation by OLE and passes the excel file created earlier then it gives no dump and is executed successfully.
Kindly help on this.

Hi Suchendar,
Try using the FM - F4_FILENAME to get the valid file name and use TEXT_CONVERT_XLS_TO_SAP FM to upload into SAP based on the required format.

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 Visibility in uploading the file using web DynPro java

hello,
i have gone through the tutorial " uploading & downloading the file using web DynPro java".
the upload functionalty is working fine. but i need to know thw path where these files are getting uploaded ??
Waiting for the reply..
Regards,
Viren Gupta

Hi Viren,
Are you are refering to the below tutorial for upload and download:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b0e10426-77ca-2910-7eb5-d7d8982cb83f?QuickLink=index&overridelayout=true
If yes, then answer is that the file is stored in the context of the application only as "com.sap.ide.webdynpro.uielement-definitions.Resource" object. Please read through the tutorial to understand the full process.
WD doesn't really upload to server automatically unless there is any explicit code written. All it does is to store the file in a temp context which you can access and write your own code to store it in a particular location.

Mahesh

Error in uploading excel file using Java pages

Hello,
We are using oracle ERP (R12.1.1) and we have developed one JSP page to upload an excel.
After selecting the excel and browse button is clicked we are gettign the OLE stream error when the excel file is .csv or .xlsx. There is no issue with .xls excel files. For loading the excel data to custom table we are using the "jxl-2.6.jar".
Can we get higher version of "jxl-2.6.jar to support CSV upload?
Thanks.

Are you Registered this jsp upload page to EBS before test?
You have to register the page to EBS first.
