Mandate OneClass packs all your Java application classes into a single .class file! It provides four key benefits to developers. 1. Improves usability and the end-user's experience. 2. Eliminates Classpath Headaches. 3. Discourages decompilation and reverse engineering. 4. Creates trial editions that expire after a certain time or use count. On execution .classes are never unpacked to disk, just executed out of the single file, delivering convenience while increasing protection
