Running Railo 3 on JBoss 5
Edit: Better way of fixing the classloading errors (credit to http://nagpals.com/blog/post.cfm/classloader-conflicts-in-railo-on-jboss for the solve, and other good stuff):
The correct way to fix this issue is to make JBoss isloate classes loaded for different applications, thereby removing the possibiiity of conflicts. On JBoss 5 you can do this if you add a file in WEB-INF/jboss-classloading.xml that contains:
<classloading xmlns="urn:jboss:classloading:1.0"
name="mywar.war"
domain="DefaultDomain"
export-all="NON_EMPTY"
import-all="true">
</classloading>
FWIW, I like to keep everything in an EAR, and use an application.xml file to define the context, etc..
Eventually I'll post an entry on creating an EAR deployment with CF/Railo, as it's pretty easy.

Would be really keen to see how you created an EAR deployment with CF/Railo.
Thanks,
