JSR-223 - Where to find ScriptServlet?

I'm confused as to where exactly I should find com.sun.script.http.ScriptServlet that I've seen in numerous samples across the web.

Is JSR-223 included in JDK 1.6? I've seen people talk about a reference implementation, but the only working link on Oracle's site doesn't seem to in开发者_JAVA百科clude such a class. My non-local environment also uses OpenJDK, which I doubt would have any Sun implementation of JSR-223 anyway! In this case where can I get it from? I'm not even sure what 'it' is in this scenario :/

I want to be able to use PHP as a view technology, invoked from a Servlet. I gather JSR-223 was designed with this sort fo usage in mind, but I'm struggling to figure out

Edit

One guide in particular (http://acet.rdg.ac.uk/projects/vre/jsr223inst.php) mentions invocation of PHP via JNI, which sounds ideal. If there's something in existence as part of the final spec that'd allow me to do this via Servlet, I'd be a very happy bunny.

It's available here. Below is an extract of relevance:

Previously, Ludo and Arun described how to run PHP 5 on GlassFish using Quercus, see here and here. However, it is also possible to invoke the native PHP engine on Glassfish, using jsr223 and a PHP bridge. The following steps should work on Sparc Solaris 10.

• Download script.jar and drop it into <glassfish>/lib.
• Download libphp5-5.0.1-sparc-S2.so, save it as libphp5.so and drop it into <glassfish>/lib.
• Download phptest.war and deploy in Glassfish.
• Run the PHP on http://localhost:8080/phptest/hello.php.

The class you mentioned is contained in the script.jar file.

There's Quercus, Caucho's Java reimplementation of PHP in Java, quite easy to package as a WAR. JSR223 is included in Java 6, but the only script engine it's shipped with is Rhino, Mozilla's JavaScript interpreter. There are a number of JSR-223 compatible script engines available, check out the repository. Instructions on how to integrate Quercus in eg Glassfish can be found on Arun Gupta's blog.
