How to have java code close batch script??

I have a .bat script that launces an .exe and a java app:
:BEGIN
start /d “c:\Program files\xyz” /b xyz.exe
C:\j2sdk1.4.2_01\bin\java -classpath class_path=”.;C:\Program Files\xyz\abc\src” xyz_java.Application
:END

And i need to know how to have teh xyz_java.Application app close teh bat file on exit. Any one have any ideas?
