Install on Jboss 4.2.1 with Apache 2.2.6 with mod_proxy_ajp

[Migrated From Jforum.net]

Hello,

I try to run jforum 2.1.7b3 on a server with Apache 2 with mod_proxy_ajp.
After installation I can't access the Page "http://a6.iwt-promotion.com/forums/list.page"

HTTP Status 404 -

type Status report

message

Any hint whats wrong?
An other simple struts application runs ok with a similar apache config.
