JSP, Tomcat and Threads

Is it possible to use threads with JSP and Tomcat ? My web application is based on JSP and JavaBeans accesing database. Now I want to create new threads that should work like agents, interacting with other agents in the same application. Is this possible ? I wonder if the threads will "stay alive" even after the jsp page or bean that created it has finished executing ! Please, any help is welcome !

Yes you can do anything in a servlet (or JSP) that a free-standing Java application can do (subject to possible security control by the servlet engine). There is nothing magic about the servlet environment that changes the way Threads operate.
I have used separate Threads to manage sending email, load headlines from another site, etc.
You do have to think very carefully about synchronization issues,etc - keeping in mind at all times that your JSP may be handling multiple requests "at the same time."
