J2Exe is simple application that makes an executable file or windows
service for
your java application. The output file uses default java which is
installed on
PC in order to launch your java application. You can start it with
specific
java version if you put it in bin directory of this java version.
Supported
versions till this moment are JDK1.1.x, JDK1.2.2, JDK1.3.x, JDK1.4.x
and
JDK1.5.x of Sun Microsystems, Inc.

Produced executable file (or windows service) might be an
application with
standard console, without it or with managed console. Applications
without
standard console are similar to java application started with javaw.
Applications with managed console are my idea. They are new type of
java
applications. If you build executable file (or windows service) with
managed
console then you can find a menu item in system menu of every frame
of your
java applications. This menu item will give you the possibility to
show and to
hide console of your applications. This is useful for testing
purpose because
you can show standard console and to dump stack traces of all
threads. During
the rest of the time the console is hidden and your taskbar is free
of it.

J2Exe project is distributed as three independent modules:

J2Exe: Generates standard executable file.
J2TrayExe: Generates standard executable file with "tray"
capability. User can
minimize your application into tray area. There are provided 2
additional
classes - WinTray.java and WinTrayListener.java. Developer can use
them to
embed his own menu items into tray popup menu of application and to
receive
notification events when user clicks one of them. No additional
natives are
required.
J2WinService: Generates standard windows service.
J2TrayWinService: Generates standard windows service with "tray"
capability.
