9. Create Controller for page FileUploadPG

Right Click on PageLayoutRN > Set New Controller

Package Name: fileupload.oracle.apps.fnd.fileuploaddemo.webui

Class Name: FileUploadCO

Write Following Code in FileUploadCO processFormRequest

import oracle.cabo.ui.data.DataObject;
import java.io.FileOutputStream;
import java.io.InputStream;
import oracle.jbo.domain.BlobDomain;
import java.io.File;
import oracle.apps.fnd.framework.OAException;

public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
{ super.processFormRequest(pageContext, webBean);

if(pageContext.getParameter("Submit")!=null)
{
upLoadFile(pageContext,webBean);
}
}

CODE #1 -- If Page has not deployed at instance, testing at Local Machine, use following Code

public void upLoadFile(OAPageContext pageContext,OAWebBean webBean)
{ String filePath = "D:\\vishnu";
System.out.println("Default File Path---->"+filePath);

String fileUrl = null;
try
{
DataObject fileUploadData = pageContext.getNamedDataObject("MessageFileUpload");

//FileUploading is my MessageFileUpload Bean Id
  if(fileUploadData!=null)
  {
   String uFileName = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_NAME");
   String contentType = (String) fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE");
   System.out.println("User File Name---->"+uFileName);

FileOutputStream output = null;
InputStream input = null;

   BlobDomain uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, uFileName);
   System.out.println("uploadedByteStream---->"+uploadedByteStream);

   File file = new File("D:\\vishnu", uFileName);
   System.out.println("File output---->"+file);

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.close();
   input.close();
  }
}
catch(Exception ex)
{
  throw new OAException(ex.getMessage(), OAException.ERROR);
}
}

CODE #2 -- If Page has been Deployed at Instance, Use Following Code

public void upLoadFile(OAPageContext pageContext,OAWebBean webBean)
{ String filePath = "/u01/app/apnac03r12/PRajkumar/";
System.out.println("Default File Path---->"+filePath);

String fileUrl = null;
try
{
DataObject fileUploadData = pageContext.getNamedDataObject("MessageFileUpload");

FileOutputStream output = null;
InputStream input = null;

   BlobDomain uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, uFileName);
   System.out.println("uploadedByteStream---->"+uploadedByteStream);

   File file = new File("/u01/app/apnac03r12/PRajkumar", uFileName);
   System.out.println("File output---->"+file);

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);
