Front-end upload form and JS in the Jqupload download has a simple code to achieve, simply add the form element as required.

The code in the servlet is referenced as follows:

Smartupload mysmartupload = new Smartupload ();
Mysmartupload.initialize (Getservletconfig (), request,response);
try {
Mysmartupload.upload ();
catch (Smartuploadexception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
Request req = Mysmartupload.getrequest ();
for (int i = 0; i < Mysmartupload.getfiles (). GetCount (); i++) {
Com.jspsmart.upload.File File = Mysmartupload.getfiles (). GetFile (i);
if (file.ismissing ()) continue;
try {
File.saveas ("z://uploadtemp//" + file.getfilename ());
catch (Smartuploadexception e) {
TODO auto-generated Catch block
E.printstacktrace ();
}
}
