JSP does not mandate Java as the scripting language; for instance,
Caucho's Resin has a JavaScript implementation.
It's possible to access CORBA and COM objects from Java, so you can
integrate with legacy systems.
Java VMs are very widely available, much more than ASP ports to other
OSes and servers. And even if that were not the case, I personally would
rather not tie myself to a "standard" that can be changed or dumped
overboard on a whim by a single company.
