JBoss AS and .Net Integration Offerings
Since Microsoft has standardized its web services implementation around SOAP, a good way to integrate .NET and Java is via web services. Our web services implementation does support SOAP messages. http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossWS is a good launch point to learn more. .NET clients, if they communicate via web services, can talk to our JBossWS back-end via SOAP. Also, you can expose any SLSB (Stateless Session Bean) as a web service, http://docs.jboss.org/jbossas/getting_started/v4/html/ws.html.
