My Findings ...: OAF Page to Upload Files into Server from local Machine

OAF Page to Upload Files into Server from local Machine

1. Create a New Workspace and Project

File > New > General > Workspace Configured for Oracle Applications
File Name – PrajkumarFileUploadDemo

Automatically a new OA Project will also be created

Project Name -- FileUploadDemo
Default Package -- xxcmn.oracle.apps.fnd.fileuploaddemo

2. Create a New Application Module (AM)
Right Click on FileUploadDemo > New > ADF Business Components > Application Module
Name -- FileUploadAM
Package -- xxcmn.oracle.apps.fnd.fileuploaddemo.server
Check Application Module Class: FileUploadAMImpl Generate JavaFile(s)

3. Create a New Page
Right click on FileUploadDemo > New > Web Tier > OA Components > Page
Name -- FileUploadPG
Package -- xxcmn.oracle.apps.fnd.fileuploaddemo.webui

4. Select the FileUploadPG and go to the strcuture pane where a default region has been created

5. Select region1 and set the following properties --

Attribute	Property
ID	PageLayoutRN
AM Definition	xxcmn.oracle.apps.fnd.fileuploaddemo.server.FileUploadAM
Window Title	Uploading File into Server from Local Machine Demo Window
Title	Uploading File into Server from Local Machine Demo

6. Create messageComponentLayout Region Under Page Layout Region
Right click PageLayoutRN > New > Region

Attribute	Property
ID	MainRN
Item Style	messageComponentLayout

7. Create a New Item messageFileUpload Bean under MainRN
Right click on MainRN > New > messageFileUpload
Set Following Properties for New Item --

Attribute	Property
ID	MessageFileUpload
Item Style	messageFileUpload

8. Create a New Item Submit Button Bean under MainRN
Right click on MainRN > New > messageLayout
Set Following Properties for messageLayout --

Attribute	Property
ID	ButtonLayout

Right Click on ButtonLayout > New > Item

Attribute	Property
ID	Submit
Item Style	submitButton
Attribute Set	/oracle/apps/fnd/attributesets/Buttons/Go

9. Create Controller for page FileUploadPG
Right Click on PageLayoutRN > Set New Controller
Package Name: prajkumar.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:\\temp";
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:\\temp", 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 = "/Unix Path/";
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("/Unix Path/", 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);
}
}
