The Soapmill comes with almost all the supporting libraries; the only thing you'll need is Java 1.4.1 and a servlet container like Jakarta Tomcat.
It has been tested on Mac OS X, Windows and Linux.
Here are the Soapmill versions we have the most confidence about.
Use the Soapmeter to debug your Soapmill software.
If you want to improve the Soapmill, we would more than welcome your contribution. Send me an email (kow at loria point fr), and i will add you to the developer list.
