Looks like a classloader issue. My guess is that you have the shiro
jars in the war files, rather than at the same level as the ehcache
jar? In order for this to work, both applications would need to load
the shiro classes from the same classloader. This probably means
putting the shiro jars at the server level, the same way as you have
done ehcache. (org.apache.shiro.session.Session loading in application
A != org.apache.shiro.session.Session loaded in application B)
Hope that helps,
Jared
