I got an executable jar file out of eclipse and I want to distribute my application to my clients. But the glitch is I donot want them to have JDK/JRE installed on their machines.
Is there anyway I can do that ?
This was a bigger deal 10 years ago than it is now. I'm not sure why that is, but I guess people don't distribute stand-alone Java applications as often, or stand-alone programs at all for that matter. Anyway, what you probably need is a Ahead-of-time (AOT) compiler. There's a good article about it here.
More commonly now people use Java Web Start. If you set it up correctly, you just post your application on your website and the JNLP code in your web page takes care of making sure the user has the correct JRE on their system.
(I disregarded your desire for the user to not have the JRE on their machine because it seemed misguided. Why would you not want that?)
