This is supported by all servlet engines I've used (JWS, Apache JServ, JRun,
ServletExec, WebSphere and our own WAICoolRunner and LiteWebServer products).
The way it's done is that you configure the same class with different names
and init arguments, typically in the servlets.properties file (or through
the Admin GUI). Example:
servlet.firstName.code=MyServlet
servlet.firstName.initArgs=param1=foo
servlet.secondName.code=MyServlet
servlet.secondName.initArgs=param1=bar
You can then access the two instances as /servlet/firstName and
/servlet/secondName, and each will be initialized with its own
init args.
