Questions tagged [javaw]

The javaw tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.

The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear. The javaw launcher will, however, display a dialog box with error information if a launch fails for some reason.
