Answer 1

public void doPost( HttpServletRequest request,
HttpServletResponse response ) throws IOException,
ServletException
System.out.println("request.getContentType()" + request.getContentType());
ServletContext sc = getServletContext();
// Here I want to put my files on server ..
String path = sc.getRealPath( "/testfiles" );
org.apache.commons.fileupload.DiskFileUpload fu = new org.apache.commons.fileupload.DiskFileUpload();
fu.setSizeMax( -1 );
fu.setRepositoryPath( path );
try
List l = fu.parseRequest( request );
Iterator i = l.iterator();
while (i.hasNext())
FileItem fi = (FileItem) i.next();
File file = new File(fi.getName());
fi.write( new File(path,file.getName()));
catch (Exception e)
throw new ServletException( e );
String forwardFileName = (String) request.getParameter( "h" );
if (forwardFileName != null)
if (forwardFileName.indexOf( ".jsp" ) == -1)
forwardFileName = forwardFileName + ".jsp";
response.sendRedirect(forwardFileName);
