How do I best install your product

Since AXT is written purely in Java you can install it on various Operation Systems. You can always run as many Gateways on each systems as you want, just ensure that every Gateway has its own directory. This even works on Windows as the Java applications are not entered in the system registry. If you want to run Accent XML Transformer under Windows you can use AtYourService (http://www.prismmicrosys.com/atyourservice/ atyourservice-index.htm) to run it as a service that will automatically start with the server. This option will also allow you to catch the error if an error occurs, isolate the wrong file and restart the service. This has been used by many of our customers to ensure a flexible SLA approach.
