> I will mark PHP/Java Bridge version 6 as "experimental"

Done. Current stable download is PHP/Java Bridge 5.5.4.1

The next version, PHP/Java Bridge 6.2.1, will contain the following changes:

* Use the WebSocket protocol instead of HTTP/1.1 chunked connection

* Dropped support for all application servers which do not support the
WebSocket protocol. This means: Jetty 7 only.

* JSR 223 script engine improvements: FastCGI instead of CGI and
getInvocablePhpScriptEngine() w/o the URI parameter for local script
invocation and implementation of the Compilable interface.

Hi Brian,

you should probably keep using PHP/Java Bridge version 5.x instead.

If it is true that the timeout cannot be configured reliably ( see
http://marc.info/?l=tomcat-dev&m=115956945015246&w=3 ), the PHP/Java
Bridge version 6 becomes useless, until tomcat supports a reliable,
persistent communication channel. For example WebSockets.

I will mark PHP/Java Bridge version 6 as "experimental" and will check
the tomcat 6 source code.

Thanks again for reporting this issue!

Great, thanks for the quick response.  I've updated my tomcat timeout and
everything seems to be working well enough now.

Thanks for the help,
Brian

Hi Brian,

> sleep(30);

the default tomcat keep-alive timeout is 20000ms. If your script
doesn't send any data within 20seconds, tomcat closes the connection.

Please change tomcat's server.xml to

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="40000"
               redirectPort="8443" />

(there's no separate keepAliveTimeout; Tomcat uses the
connectionTimeout for the keep-alive as well)

The hanging at the end of the script is another problem. PHP/Java
Bridge 6.0 uses HTTP/1.1 chunked connections, which require a shutdown
sequence. From the current Java.inc:

 for ($this->res=$this->fread(10); strlen($this->res) < 10;
$this->res.=$this->fread(10-strlen($this->res)));

The "10" is the <F t="E"/>, which is okay. But I should have checked
that the connection is still alive. Or simply replace the for loop
with fread($sock, 10), as tomcat won't send the 10 bytes
one-after-the-other.


Thank you very much for reporting this issue.

I had a hanging problem but at the same time my script was not working. It
was because my I hadn't installed JavaBridge and PHP correctly. I just
re-installed both, and I didn't have the problem anymore.

It could also be something with the exit function, but I don't know
JavaBridge well enough to comment what exactly.

Sincerely,
Sravan Suryadevara
