[java] How to find where javaw.exe is installed?

So, for a project I am working on, I need to find out where a javaw.exe is located on a user's machine. How do I do that? Assuming that user is on Windows machine

The method that I used is limited to English versions of Windows only.
I looked for where the OS is installed, locate the Program Files directory, locate Java, jdk directory, bin, then javaw.exe. I know this will not work on non-English versions of Windows.

What is the human-language-independent way to do this ?

Open a cmd shell,

cd \\
dir javaw.exe /s

To find "javaw.exe" in windows I would use (using batch)

for /f tokens^=2^ delims^=^" %%i in ('reg query HKEY_CLASSES_ROOT\jarfile\shell\open\command /ve') do set JAVAW_PATH=%%i

It should work in Windows XP and Seven, for JRE 1.6 and 1.7. Should catch the latest installed version.

It worked to me:

    String javaHome = System.getProperty("java.home");
    File f = new File(javaHome);
    f = new File(f, "bin");
    f = new File(f, "javaw.exe"); //or f = new File(f, "javaws.exe"); //work too
    System.out.println(f + "    exists: " + f.exists());

Try this

for %i in (javaw.exe) do @echo. %~$PATH:i
