Observe the following in the java executable documentation:

http://java.sun.com/j2se/1.4.1/docs/tooldocs/linux/java.html#-jar

Using the -jar command makes java ignore all other classpath settings 
except what is specified in the JAR's manifest file.

What I would recommend that you do is put all the JARs that MyMail.jar 
requires in the same directory and add the following to MyMail.jar's 
manifest:

Class-Path: xerces.jar jdom.jar

See the following for more information about the format of the JAR manifest:

http://java.sun.com/j2se/1.4.1/docs/guide/jar/jar.html#JAR%20Manifest

Ciao,
Gordon
