Uploading File into server from local machine

Hi
Friends, I just inform to you that, the following article is published by mukul's, but even though i want to publish this article for my friends and dearest one's.

Through my OAF page i want to upload the file from local to server.

Step 1: Create the page with two items
               
           a. MessageFileUpload Bean
           b. Submit Button.
Step 2: Now write the below logic in the controller class

 public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
  {
    super.processFormRequest(pageContext, webBean);   
    if(pageContext.getParameter("Submit")!=null)
    {
             upLoadFile(pageContext,webBean);     
    }                     
  } 
 public void upLoadFile(OAPageContext pageContext,OAWebBean webBean)
  {
                    System.out.println("Action Performed");

                    String filePath = pageContext.getProfile("FILE_UPLOAD_PATH");

                    System.out.println("Default File Path---->"+filePath);

                    String fileUrl = null;

                    try

                    {

                      DataObject fileUploadData =  pageContext.getNamedDataObject("FileUploading"); //FileUploading is my MessageFileUpload Bean Id

                       if(fileUploadData!=null)
                      {

                        System.out.println("BeanId is also Not null");


                        String uFileName = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_NAME"); // include this line

                        String contentType = (String) fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE"); // For Mime Type

                        System.out.println("User File Name---->"+uFileName);

                        FileOutputStream output = null;

                        InputStream input = null;

                        System.out.println("am In try block---->");

                        BlobDomain uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, uFileName); 
                        System.out.println("uploadedByteStream---->"+uploadedByteStream);
                       // File file = new File("/export_home_dev/user/oracle", uFileName); //once you deploy the page uncomment this line and give your server path according to your fish
                        File file = new File("D:\\santhosh", uFileName); // comment this line once you deploy the page into server
                        System.out.println("File output---->"+file);

                       // output = new FileOutputStream("D:\\Kumar"+uFileName);

                        output = new FileOutputStream(file); 

                        System.out.println("output----->"+output);

                        input = uploadedByteStream.getInputStream();

                        System.out.println("input---->"+input);
                        byte abyte0[] = new byte[0x19000];
                        int i;
 
                       while((i = input.read(abyte0)) > 0) 
                        output.write(abyte0, 0, i);

                       // output.write(uploadedByteStream.getBytes(0,(int)uploadedByteStream.getLength()));
                        output.close();
                        input.close();
                      //  fileUrl = (String)file;
                      }
                    }
                   catch(Exception ex)
                    {
                      throw new OAException(ex.getMessage(), OAException.ERROR);

                    }     
   
  }
Step 4: Now Run the page and see the output.

Step 5: Before going to see the output, i will show you, in my local mahcine i don't have file called
"BT_GEOCode_Order_To_Cash.xls" file
     

Step 6: Now Run the page and Browse the file
   

Step 7: Now check the Browsed file called  "BT_GEOCode_Order_To_Cash.xls" file in the local machine

Note: This application is working in local machine only , because i gave my local path for the saving purpose, so if you want to save the file from local to server, then you need to do the following things

a. First change the local path to server path
b. then deploy the page and related .class and .server files from local to server
c. now run the page in the application not in the local machine(jdeveloper).
