Question

I’m programming a homepage and I need to connect to JAVA and send some encrypted information to java and getting some back. How should I do this?

Answer 1

Just give you an idea

1. compile and build your JAVA program, and your program should accept command line arguments as input and write output to STDOUT (i.e. write to System.out using System.out.print and such.)
2. Then, in PHP, use exec() to execute that jar file.
