By nature, Java programs are usually interpreted by a JVM. The Java process you see is that JVM instance in fact.

To make what you want, you have to encapsulate the JVM in your own program so that you have apparently only one executable (and no JVM dependencies for your users).

I recommend you to have a look to these free projects:

Doing a query like "java to exe" in Google can also helps to find the latest news. Looking into gihub could also help to find latest tools.

Note that if you do that, you loose one nice feature of Java which is cross-platform portability.

There are alternatives like JNLP and others.

A really simple way would be to make a copy of java.exe (or javaw.exe) under the name you want, and call this instead of java(w).exe

Something I have seen is that you could create your own executable file which in turns launches your Java application as a child process; you can name your executable file as you wish. Your parent process will wait until the child process returns (it is killed or finished), additionally you could add some logic so that if the parent process is terminated, the child process will also be terminated (but this could be tricky to implement and may not work for a hard abort or SIGKILL).

The big problem with this solution is that you will have to create code that is platform independant.
