It's portable and the standard is vendor-neutral. If you write to (say)
Netscape's or IIS's proprietary interface, you've just tied yourself and
your customers to a single source for software and support.
However, portability doesn't mean that all servers run the same app
equally well. Websphere and Weblogic may (or may not!) run this
portable code faster or using fewer resources than the open-source
servers. Most of the time this is impossible to tell without evaluating
the options yourself, as for some reason most commercial licenses forbid
publishing benchmarks of their software <sigh>.
