Asynchronous messaging in tomcat

[Gehl, Pascal]

Hi,
 
I know we are not supposed to do this but is there a big inconvenience
to do asynchronous message consuming in tomcat 5+ (by spawning a daemon
thread for my message listener ?)
Is it true that if a I create a thread on my own I won't have access to
the tomcat JNDI context ?
 
I ask this because we really don't want to use an EJB container only for
MDB.
 
thanks
