PHP on JRun doesn't work just yet

A number of us have been following Sean Corfield's JSR-223 experiments with interest. The PHP flavour relies on Quercus, part of the Resin J2EE app server.

For some fun, I deployed Quercus next to CF 8 on the Multiserver install. As it turns out, this won't work with Quercus in its current form as JRun implements an older Servlet Spec (version 2.3). Quercus uses ServletRequest.getRemotePort(), which is part of the 2.4 version of the spec; this is the error that occurs with apps like phpBB and DocuWiki (and anything else that uses $_SERVER):

error javax.servlet.http.HttpServletRequest.getRemotePort()I [1]java.lang.NoSuchMethodError

Of course, Quercus could be rewritten for JRun to get around this.
