Okay, that makes sense: pages called directly from my AS will of course be
running in a Servlet context.

What if I call
   http://localhost/testJava.php

and testJava.php file includes the (pure Java) PHP/Java bridge and makes a
call on a new Java object.

This behavior relies on the JavaBridge Servlet running in the AS (in my
case: Tomcat). (This is setup in my php.ini, of course.) If the JavaBridge
servlet is not running then the Java call(s) will fail.

So in this instance, Tomcat *does* see the request, or at least the Java
portions of it, but the java_context() isn't established(?).

Which I've done a lot of, and it seems to be working well.

The issue though, is some of the Java classes I'm using want to write out
(D)HTML using objects that exist in the Servlet context - obviously that
won't work if being called from Apache -> PHP -> Tomcat Java/Bridge.

I suppose my other option would be to run the PHP file from Tomcat instead
of Apache... that may not be so bad, but it feels like then I'm just a step
away from using pure Servlets + JSP and I could drop PHP entirely. :)
