OAF Page to Upload Files into Server

1. Create a New Workspace and Project
File > New > General > Workspace Configured for Oracle Applications
File Name – FileUploadDemo
 
Automatically a new OA Project will also be created
 
Project Name -- FileUploadDemo
Default Package -- xxupload.oracle.apps.fnd.fileuploaddemo
 
2. Create a New Application Module (AM)
Right Click on FileUploadDemo > New > ADF Business Components > Application Module
Name -- FileUploadAM
Package -- xxupload.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 -- xxupload.oracle.apps.fnd.fileuploaddemo.webui

4. Create a New Item messageFileUpload Bean under MainRN 
  
Right click on MainRN > New > messageFileUpload
Set Following Properties for New Item -- 
ID:MessageFileUpload
Item type:MessageFileUpload 



Write Following Code in FileUploadCO processFormRequest
import oracle.cabo.ui.data.DataObject;
import java.io.FileOutputStream;
import java.io.InputStream;

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