Description:

The Launcher Component is designed to be a cross platform Java application
launcher, originally coming from the Jakarta Tomcat 4.0 project.

Commons-launcher eliminates the need for a batch or shell script to launch a
Java class. Some situations where elimination of a batch or shell script may
be desirable are:

* You want to avoid having to determining where certain application paths are
e.g. your application's home directory, etc.
Determining this dynamically in a Windows batch scripts is very tricky on
some versions of Windows or when softlinks are used on Unix platforms.
* You want to avoid having to handle native file and path separators or native
path quoting issues.
* You need to enforce certain system properties e.g. java.endorsed.dirs when
running with JDK 1.4.
* You want to allow users to pass in custom JVM arguments or system properties
without having to parse and reorder arguments in your script. This can be
tricky and/or messy in batch and shell scripts.
* You want to bootstrap system properties from a configuration file instead
of hard-coding them in your batch and shell scripts.
* You want to provide localized error messages which is very tricky to do in
batch and non-bash specific shell scripts.
