Re: Class generator

Hello Rolf,

I'll do my best to the JDOM community :-)

This example was compiled with JDOM 1.1.1 and jdk 1.3.1 on a j2se 1.2
eclipse environment, because my Ubuntu 11.10 won't execute the java 1.2.1
binaries (only my virtual CentOS 2...).

About your observations: my first post was about asking if there was a
"tool" that would create those classes automatically from a xsd file (or a
xml file like EditiX). In my approach, the only "hard" work is to copy the
toXML() method to each class. But in the end, you're right :-)

Maybe a ToDo tool for JDOM :-)
