JumpLoader
Java File Upload Applet

Home

JumpLoader screenshotJumpLoader 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.

Websites having java applets should be hosted through some best web hosting (try also Linux Hosting) company with low budget, and for wordpress we recommend to check wordpress hosting services.
