We are going to create Jar Store the way like App Store works, but for Java Developers.
Everyone will able to submit and sell custom .jar library which solves some little problem, but solves it very good to save other developer’s work time.
The only undecided question is how to prevent .jar copying or publishing bought .jar to the Net.
EDIT: This can probably achieved by using strong copyright policy? Suggest please!
EDIT 2: I imagine Steve Jobs asking:
How we can prevent iPhone Apps from copying? — You can't it's just a files on the iPhone which can be easily copied by anyone.
