Try changing the context name of the jboss-net.war
An alternative is to add your own Axis servlet (JBoss.NETis basically Apache Axis), with it's own context. As the Axis libraries are already on the classpath as part of the jboss.net install the only files needed in the war for the axis servlet are web.xml and the axis config. This also allows you to enforce servlet security on individual webservices by putting them behind different servlets. the apache Axis documentation describes how to configure and secure Axis servlets.
