compiling php with Java - nothing happens

[R]

Hello everybody.

I've got very simple question.

I'm runnig my configure script with this option:

--with-java=shared,/opt/jdk1.5.0

(just like it is said - http://www.php.net/manual/en/ref.java.php)

java is meant to be build as shared library,
--with-java points to my jdk directory

make && make install - no errors

but...

in directory modules there're only: tidy.so, domxml.so and mysql.so -
but no java.so or sth like that

what am I doing wrong?
(there has to be sth because java isn't compiled)

gest regards R
