Instantiating an upload bean

Class
Mysmartupload.initialize (PageContext);
Set the maximum upload value
Mysmartupload.setmaxfilesize (500 * 1024*1024);
Uploading files
Mysmartupload.upload ();
Loop to get all uploaded files
for (int i=0;i <mysmartupload.getfiles (). GetCount (); i++)

Get the uploaded file

Get filename with no suffix
String suffix=myfilename.substring (0,myfilename.lastindexof ('. '));
Get suffix Name
