Application

Java

The supported Java version is Oracle Java 11 OpenJDK.

We recommend and test with AdoptOpenJDK version 11.0.8+10.

Application Server

The supported Application server is Tomcat 9.

The supported Proxy protocol is the Apache JServ Protocol (AJP).

Webserver

Instead of specifying specific web servers like Apache and IIS, we support the protocol/connecter to Tomcat 9. To allow for clients currently running Apache 2.2, we will support both the HTTP proxy and the AJP proxy for a number of releases to allow for an easier transition.

Support for the HTTP proxy was discontinued after Nov 1st, 2019.

We strongly advise that if you are running Linux that Apache 2.4 is configured with an AJP proxy to Tomcat 9.If you are using Apache 2.2, then you will need to use an HTTP proxy with your Tomcat connector configured as follows:

Please contact our Support team, who will be happy to advise on the best configuration to suit your technology base.
