Upload Files into Server in OAF Dynamically

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 -- xxcustom.oracle.apps.fnd.fileuploaddemo
 
2. Create a New Application Module (AM) 

Right Click on FileUploadDemo > New > ADF Business Components > Application Module 
Name -- FileUploadAM
Package -- xxcustom.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 -- XxchrFileUploadPG 
Package -- xxcustom.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 XxchrFileUploadCO processFormRequest
import oracle.cabo.ui.data.DataObject;
import java.io.FileOutputStream;
import java.io.InputStream;
import oracle.jbo.domain.BlobDomain;
import java.io.File;

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