Executing java apps without individual JAR file entries in CP???

Question

Hi all,
I'm used to having to specific EACH separate jar file in the CLASSPATH when executing a java application. See the batch file example below.
Is there a way to not have to spell out EACH JAR file separately in this fashion? Eg just refer to the JAR directory?
What do people usually do here when delivering a java application to someone else, given the application has your own class files in a JAR, plus other 3rd party class files? Do you always have to build up a long JAVA batch file like the one below to enable the application to be run?
-----------example-------
c:\Progra~1\jdk1.3.1\bin\java -classpath .;deploy\mail.jar;deploy\activation.jar;deploy\xerces.jar;deploy\commons-digester.jar;deploy\commons-collections.jar;deploy\commons-beanutils.jar sns
Cheers
Greg

A simple way is to have a class inside your program load all the JAR files needed.
That way, when the main class file starts, place a call to the class that will load
the classes for you. Like this one below...
import java.lang.*;
public class MyJarLoader {
public MyJarLoader() {
System.load(String); // replace 'String' with the file pathname of a JAR file.
// you will need to do this for each JAR file, just add another call to System.load() here
