JumpLoader is a Java applet designed to upload files from the client to a server. This is a valuable replacement for <input type="file"> rudiment of HTML.
This is suitable tool for webmasters who wish to provide a better way for users to upload files to their websites. This could be photo galleries, web hosting providers or any kind of service that requires user files retrieval.
JumpLoader is free.

Known issues
Jumploader doesn't upload files in Opera browser. This is due to poor Java Plugin support by this browser (HTTP POST request never send to network, if utilizing HttpURLConnection). Will think of workaround for this issue.
Fixed since 2.80- If applet doesnt load and java console displays similar message:
java.lang.ClassFormatError: Incompatible magic value 1014264382 in class file...
most likely web server sends wrong mimetype header for JAR file. Consider registering following mimetypes for typical java files:
application/java-archive=jar
application/octet-stream=class
