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

I have recently updated my installation of the JavaBridge and I'm seeing
some very strange behavior in my PHP scripts that are using the bridge.  I'm
hoping that someone else has run into this and can give me a quick answer as
to what I can do to fix the issue.

The problem is with PHP scripts that are being run from the command line
that are using the bridge and taking more than 30s to execute.  When the
script gets to the point where it should exit it just hangs.  Below I've
included the source code of a very simple script that I've created to
reproduce the issue.  When I comment out the line to create the String
object the script runs as expected.

I'm stumped, I've tried many combinations of ideas and nothing seems to fix
the problem.  Any help will be appreciated.

Thanks,
Brian



#!/usr/bin/php
<?php
require_once 'http://192.168.0.198:8080/JavaBridge/java/Java.inc';

$jString = new Java("java.lang.String", "test");

echo "start sleep\n";
sleep(30);
echo "sleep finished\n";

echo "start exit\n";
exit(0);
echo "exit finished\n";

?>

Hi Julien,

I can confirm that

 http://localhost:8080/JavaBridge/test.php

will hang, if the browser is set to use HTTP/1.0 only (tested with
FireFox -> about:config -> network.http.version;1.0) or if there's a
HTTP/1.0 proxy in between. This is because phpinfo() generates its
response in HTTP/1.1 chunks.

But non-chunked responses work. For example

   http://yourHost:8080/JavaBridge/sessionSharing.php

even when run through a simple HTTP/1.0 only proxy.

My mistake. Line 95
http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/server/php/java/servlet/PhpCGIFilter.java?revision=1.4&view=markup
does forward before it returns (I should stop writing more than one
statement per line ... :)


> I guess I will have to ask the end users to bypass the proxy for the server

Shouldn't be necessary. At least my simple HTTP/1.0 proxy can pass the
request/result w/o problems. Which product do you use?

Hi Jost,

Well, okay, thanks a lot for your replies ! The HTTP/1.0 is the only
difference I've found between requests from local network, and
requests from the proxy. You mentioned the proxy could make a request
with a url the filter can't parse, but the urls are ok in the Tomcat
http log file.
I guess I will have to ask the end users to bypass the proxy for the server IP.
Thanks again.

Julien Mallet.

Since version 6.x the bridge requires HTTP/1.1, see NEWS file.  But
simple HTTP/1.0 GET requests should work (not tested). I will take a
look at this issue.

Okay. I just wanted to be sure that an exception report has been
returned to your browser.

> The problem not is only joomla, but Joomla with PHP/Java Bridge!

Amen. Again, joomla cannot be used with the Java.inc PHP library due
to a bug in Joomla.  In fact Joomla cannot be used with ANY other PHP
library using spl_autoload.

Please re-read http://bugs.php.net/bug.php?id=49618 and work with the
Joomla maintainer to fix this bug! We cannot help you any further.

Thanks.

Hello,
Thanks for your precious answers Jost.
I think I found the issue, but I am not able to solve it. See below.

I think i got it. The company's proxy is making HTTP/1.0 requests...

Otherwise if I disable the filter, I just got 404 status code.
Is there any way to parse correctly HTTP/1.0  ?

Yes there is an exception, but you told me before it was because my
Jre was outdated and you are right.
