The standard installation requires Jakarta-Tomcat, at v5.0.19 for a production-network service and v5.0.28 of a development-network service. Other containers, and other versions, of Tomcat might work but may introduce subtle errors. No other containers and versions are supported; Tomcat v5.0.28 is only supported in the sense that it is being used for AstroGrid's internal development.
The web-application will probably not work in containers other than Tomcat. If you try one and get it to work, then please let the AstroGrid project know. If you try a container and hit problems, then it is likely that the web-application would need to be changed to run in this container. This is not a bug: AstroGrid components are not designed to work with other containers.
Tomcat versions in the 5.0.x series can probably run the web-application. Versions after 5.0.19 are most likely to work.
Tomcat versions in the 5.5.x series cannot run the web-application when Tomcat runs with Java 1.5; this has been shown empirically. Tomcat 5.5.x reconfigured for Java 1.4.x might work.
Tomcat versions in the 4.1.x series might work.
Tomcat versions in the 3.x series cannot run the web-application. They support an older edition of the servlet standard; the web-application requires servlet v2.3.
