Yes, if you use Java Uploader on 000WebHost... however it is glitchy and misses files out... so if you do use it, you will need to check through every folder and find any missing files...
If you're going to use x10Hosting, you can upload the ZIP file of the Mys script, and extract it, and then select ALL the files inside the "Installation" folder, and move it out and then delete the folder.
