Quoting from the Struts User's Guide: "The controller servlet creates only one instance of your Action class, and uses it for all requests. Thus, you need to code your Action class so that it operates correctly in a multi-threaded environment, just as you must code a servlet's service method safely.
The most important principle that aids in thread-safe coding is to use only local variables, not instance variables, in your Action class. Local variables are created on a stack that is assigned (by your JVM) to each thread request, so there is no need to worry about sharing them."
