Making java bytecode easier to execute

[kestrel7]

Hi
I am wondering if there is an alternative to distributing Java programs with the JVM.

For instance, I am wondering if anyone has seen a Java compiler that produces machine code rather than bytecode? I've heard of them, but never ever seen them
(Yes, I know I lose the 'compile once, run everywhere' property but I'm willing to make that sacrifice

Alternatively, what is the easiest way to make the Java class file seem 'executable'
(but using the JVM). My Current approach is to use a bat file (or shell script). With the bat file I simply associate my .class files with it and I can then run it by double-clicking the class file containing my main method. However, some people find this a bit confusing since they are not used to running .class files. Is there a better way of achieving this?

If you are supporting Windows, look into converting the program into a .exe file. I can't remember the process exactly(and I'm not at my PC), but a search in java forums(like SUN or another java forum) should point you in the direction.

Hi

Thanks for your help. I've had a look on the Sun forum but the best I can seem to come up with is a shareware proggy that does this. However, I was looking for something a bit more permanent (and a bit more free ) .... so any other ideas would certainly be appreciated.

Has anyone heard/seen a compiler that compiles java code to machine code?

Whenever the java/c++ speed debate comes up, someone ALWAYS mentions the existence of a java compiler to compile directly to machine code which is supposedly narrowing the speed gap ... I, however, have never seen anything like that. So I'm wondering if it's a myth (like dry land) or does it really exist?
