I am writting a DLL that can be used in a Java program and should not be used in another programs without express permission. I want to identify the program that is using my DLL and I want to know how can I do it. I have thought about accessing the JVM and finding out wich classes are loaded, and then storing the CRC of those classes in my DLL database. But I would not know what I could consider a Java 'program'. I have also thought about learning from the JVM somehow wich class was the first one loaded [the one with a static main()] and then locating its .class on the disk. But that would leave me on the same dillema: what else could I consider part of the 'program'?    More>>
