Supported Platforms

This document describes the various platforms and environments that are supported by Websydian as part of the license agreement.

Please note that Websydian applications can run in other environments than described here, but these environments are not part of the maintenance agreement.

If you need help with an environment or server not mentioned in this document then please contact Websydian Support for further information.

WebsydianExpress variants

These are the supported combinations of WebsydianExpress

• Pure IBM i variant, where application and database resides on an IBM i and the option of deploying the Web Server Component to either WebSphere on IBM i or a PC based servlet engine of your choice.
• Pure Windows variant, where application is deployed on a Windows PC and the database is deployed on a Microsoft SQL Server. The Web Server Component is deployed on a servlet engine of your choice.
• Pure Java variant, where the application is deployed as a servlet on a servlet engine of your choice and the database is deployed on either a Microsoft SQL Server or an IBM i DB2.
• A combination of Windows and IBM i programs, where the Websydian client part is deployed on a Windows PC and the database and back-end programs are deployed on your IBM i. The Web Server component is deployed on a PC based servlet engine of your choice.

We recommend using either a Tomcat or for the IBM i a WebSphere servlet engine and will provide support for these.

Distributed Websydian Architecture (DWA)

A Websydian application generated and built for the Distributed Websydian Architecture (DWA) is deployed in a 3-tier environment with a web server tier (Web Server Component), application tier (Application Service) and a database tier.

Web Server Tier

In DWA a Web Server Component is installed on the web server tier. The Web Server Component is a runtime component and is installed as either a servlet or as a CGI program.

The table below shows the web servers, servlet engines, and platforms where the Web Server Component is supported.
