php-java-bridge-users Mailing List for PHP/Java Bridge

Thank you! Yes, I understand that. Actually, I have already taken out
the if statment

if( $fuzzyRuleSet == null ) {

so I am running

$temp = $fuzzyRuleSet->toString();

directly, but it still give me an nullpointerexception. The method can
run in java just don't understand how come it cannot run in php. Any
other suggestions? Please! Thanks again!

Hmm, well me again. Sorry to bother but i feel like a dumb. I can't get rid
of my problem and i don't really get all the faces of how to use the bridge
in the way i want to use it.

Thanks for the various INSTALL files which i haven't seen at first. It
helped me a bit though. What I understood is that the JavaBridgeRunner is
the entry point of the bridge. But how do I use it. It seems that I have to
open the socket myself? I am able to make my php communicates with my java
class and get the runner but after then...

I was actually thinking about using something like a stub on the php side,
which would connect to another JVM where my Java object is already
instanciated (something like RMI actually). Then I would have been able to
catch my parameters through that socket. Am I completely wrong and should
search in another direction or is it just that i missed something in the
'how to use' process?

Would you mind explaining me what i got wrong?

Thanks for your help

the RemoteHttpSessionFacade doesn't have a getId(). Please see the API documentation for details.
http://php-java-bridge.cvs.sourceforge.net/*checkout*/php-java-bridge/php-java-bridge/server/documentation/API/index.html?revision=1.17

What you want is an instance of the HttpSession, not the HttpSessionFacade. The Session can be
obtained from the request object.

the bridge simply forwards the Java statements as soon as it receives them.

Other technologies such as Soap or XML-RPC have a much higher overhead. -- mod_jk goes even
further and forwards the entire script to the back end.

Right - I tried  but apparently the session per java_session() is not aware of such methods.

$session = java_session();

echo $session->getId();

Thanks for the reference to the j2ee docs tho - those are always hard to come by.

Hope it helps.

i am not concerned about the java backend, i was just concerned if
there for some reason overhead (in terms of speed/memory) is because
of the java/php bridge, but it sounds like this is nothing we really
have to worry about then?

cheers,

RJ

thanks for the reply. i could be wrong, it's like moving the overhead to the
script rather than leaving it in java.so

The same argument applies to the above code, of course.

Use 

  (string)$fuzzyRuleSet == null 

or better 

  is_null (java_values ($fuzzyRuleSet))


for the test.

Because of the additional overhead for class registration.

Do you really want to create a Java class in each of your scripts?

Thanks for the help. But the

if( $fis == null )

is not the cause of the error. The error is from

$temp = $fuzzyRuleSet->toString();

Even I take out the null test, the error still remains. Can anyone help? Thanks!

Hi,

thanks, that explains it. I was just wondering why would you call it a bug:)
- cos having to include Java.inc in every script is really annoying, why
can't you push all the java functions into java.so?
