Class LauncherBootstrap

java.lang.Object

LauncherBootstrap

public class LauncherBootstrap
extends Object

This class is used as a wrapper for loading the org.apache.commons.launcher.Launcher class and invoking its main(String[]) method. This particular class is primary used by the Windows 95, 98, ME, and 2000 platforms to overcome the difficulty of putting a jar file directly into the JVM's classpath when using batch scripts on these platforms.

Specifically, the problem on thse platforms is when Windows uses the PATH environment variable to find and run a batch script, %0 will resolve incorrectly in that batch script.

The way to work around this Windows limitation is to do the following:

1. Put this class' class file - LauncherBootstrap.class - in the same directory as the batch script. Do not put this class file in a jar file.
2. Put the jar file containing the launcher's classes in the same directory as the batch script and this class' class file. Be sure that that the jar file is named "commons-launcher.jar".
3. Make the Java command in the batch script invoke Java use the following classpath arguments. Be sure to include the quotes to ensure that paths containing spaces are handled properly: -classpath %0\..;"%PATH%"
