hi, i need to have a global singleton that is a singleton across all 
instances of (tomcat) servlet engines.

is there an engine context in tomcat that i can access?

does this singleton work across virtual hosts?

how does this work across multple jvm's on the same machine (or does this 
not happen)?

how about when you are load balancing across different physical nodes? - do 
you need to have some system semaphore on one of the nodes to prevent 
multiple instances?

afaict so far, restarting a context, takes down all of the classes in the 
context and putting copy of singleton into a different context, seems to 
cause two instances to be created.

any pointers would be appreciated.

thanks
