如何从java代码创建* standalone * linux可执行文件

Question

I know that java intent is for gui and multi platform, but the problem I'm facing it how to release a java application into a linux servers, which I don't have control on, ie I dont know what java vm is installed if at all.

So, how do i compile this into a true standalone linux exe, do not assume any pre installed package on the target linux.

public class MyTest {
    public static void main(String[] args) {

        System.out.println("You passed in: " + args[0]);

    }
}

Answer 1

You need to specify as a requirement an installed JRE.
Otherwise you would need to deliver a JRE yourself as part of the deliverable application

Answer 2

The GNU COmpiler for Java does exactly this. Keep in mind that it will work properly only for small programs, either way you'll need a JVM.

There's also Avian , which has another approach and allows to deploy a lightweight JVM with jour application, but it still hasn't all the features of a full JRE.

Answer 3

Creating one binary from java may not be that good. You may consider tools like http://launch4j.sourceforge.net/ for creating a full installation along with appropriate jre.
