We have downloaded JBoss-EWS (Enterprise Webserver from Redhat). From what I could see it is just a bundle of Apache 2.2.17 and Tomcat 5.5.x ot Tomcat 6.0.y. The version of mod_cluster I think is 1.0, because we still have the bug that needs ServerName www.application1.nl:80 instead of www.application1.nl The mod_cluster is the RHN one, yeah.
