JavaEE Singleton on Tomcat server

Question

I am currently developing a web solution using JavaEE. I have a database connection being established through a singleton.

Will a singleton be user specfic, as in a new instance will be created for each user or will the singleton be shared across all users on the server?

Thanks

Singleton object is same for all users. Only one object will be created per application and all users will reach the same singleton object.

Singleton, if implemented properly, means there will be one instance of that class per JVM. Check out this wiki for a nice overview with code examples.
