java - image corrupted by FileUpload -

i need make http server recieving , sending images , text(less 100 characters) client. planning use json or google protocol buffer.

i studied "httpuploadserver" example in netty 4.0.6 package.

then, deleted in handler except things dealing multipart post requests.

here's part struggling with.

private void writehttpdata(interfacehttpdata data) {     fileupload fileupload = (fileupload)data;     try {         file file = fileupload.getfile();         file.renameto(new file("c:\\savedfiles\\"+file.getname()));     } catch (ioexception e) {         e.printstacktrace();     } } 

when call getfile(), gives me corrupted file. i've tested zip files, , images(png, jpeg). (btw. using postman add-on test server, wrong headers not problem)

is there way make right?

found answer on github

change

private static final httpdatafactory factory = new defaulthttpdatafactory(defaulthttpdatafactory.minsize); 

to

private static final httpdatafactory factory = new defaulthttpdatafactory(false); 

or

private static final httpdatafactory factory = new defaulthttpdatafactory(true); 

for me setting true worked!
