Hi there,
it seems that they strongly recommend to drop Tomcat 4 in favor of Tomcat 5, probably because the new versions of Java seem to be not anymore fully suitable for Tomcat 4 (also because of the new Java Auto-Update feature).

As a result, the next DimensioneX distribution will be based on Tomcat 5, and the installation procedure in the README will be rewritten.

Should you experience installation problems, please let me know so I can fix the documentation.

Thanks!
