Question

How to send HTTP File from Java App

Asked by: mscproj

I have a servlet which can accept the follow HTTP Form File operation, and save the file into the server's File System

<FORM METHOD="POST" ACTION="http://localhost:8080/servlet/servletUpload" ENCTYPE="multipart/form-data">
   Select the file to upload  : <INPUT TYPE="FILE" NAME="FILE1" SIZE="25"><BR>
   <INPUT TYPE="SUBMIT" VALUE="Upload">
</FORM>

How can I write a Java Client that does the same thing?

E.g.
java JavaUpload file_location
e.g. java JavaUpload "c:\data upload\abc.txt"

Thanks!
