No. And why would there be ;)

There are 2 things you can do with ext/java
1) create instances of java objects thru the php's java class, You should have
access of all the methods available for that object
ex.
$java = new Java("java.util.Hashtable");
$java->put("Key", "Value");
echo $java->toString();
2) php will run as a servlet engine, meaning you can run php scripts inside
Tomcat. This is done all thru native methods.

Pages are not compiled as classes they still exists as php scripts.

Well not sure exactly what you mean by accessing java servlets, You can
"access" a java servlet by simply
file("http://someserver.com/servlet/SomeJava.jsp?param=go";); That would make
the servelet execute but I might not know what you mean by access. I guess if
you wanted to you could use the Java() class to create an instance of a servlet
class and invoke its methods directly.
Accessing a EJB from a php script should be fine, (this is purely theory never
tried it or even fully thought it thru). If you take the steps that you would
to create a refrence of an EJB from java and replicate it using ext/java it
should work.
Here is a quick example from OpenEJB HelloWorld example
http://openejb.sourceforge.net/hello-world.html
<?
$p = new Java("java.utils.Properties");
//The JNDI properties you set depend
//on which server you are using.
$p->put("java.naming.factory.initial", "org.openejb.client.JNDIContext");
$p->put("java.naming.provide.url", "127.0.0.1:4201");
$p->put("java.naming.security.principal", "myuser");
$p->put("java.naming.security.credentials", "mypass");
//Now use those properties to create
//a JNDI InitialContext with the server.
$ctx = new Java("javax.naming.InitialContext", $p );
//Lookup the bean using it's deployment id
$obj = $ctx->lookup("/Hello");
//Be good and use RMI remote object narrowing
//as required by the EJB specification.
//********** This may not work with ext/java extension ***************
$pro = new Java("javax.rmi.PortableRemoteObject");
$helloHome = new Java("HelloHome");
$ejbHome = $pro->narrow( $obj, $helloHome->class);
//********** This may not work with ext/java extension ***************
//Use the HelloHome to create a HelloObject
$ejbObject = $ejbHome->create();
//The part we've all been wainting for...
$message = $ejbObject->sayHello();
//A drum roll please.
echo $message;
?>
So except for the static access to "class" from helloHome It should work.
Maybe if I get borred some time i'll try it.
> 5) Who is responsible for development of this extension?
Sam Ruby was the orig developer. I've played with it. I don't think anyone has
done any new development in awhile.
> 6) When do you expect a non experimental version will be available
When more intrest becomes of it and someone wants to claim any new
development.
