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

Hi,

Please re-read http://php-java-bridge.sourceforge.net/pjb/installation.php

The --daemon option is not meant to be used by end users.

Install a jee server to run the bridge back end. Otherwise you won't get any
support from us.

Regards,
Jost Bökemeier

Hi all,

I'm hoping someone can help me out with a problem I've been having. My aim
is as follows:

1) browse to a page generated by a php script. This script starts the
javabridge in the background like this:

$port = 9200;
$javaHosts = "localhost:" . $port;
define("JAVA_HOSTS", $javaHosts);

// define engine scope
define("ENGINE_SCOPE", 100);

// require Java.inc for handling JAVA/PHP bridge related matters
require_once ("Java.inc");

   $basePath = dirname($_SERVER["SCRIPT_FILENAME"]);
   $port = 9200;

   // check if bridge is running already
   if (!$file = @fsockopen("127.0.0.1", $port, $errno, $errstr, 2)) {

       // not running, so start bridge
       $baseCmd = "java -Dphp.java.bridge.base=" . $basePath .
"/lib/javabridge -jar " . $basePath . "/lib/javabridge/JavaBridge.jar
SERVLET_LOCAL:";
       $endCmd = " 3 " . $basePath .
"/lib/javabridge/JavaBridge.log";
       $cmd = $baseCmd . $port . $endCmd;
   }

2) create a java class object through the bridge, e.g:

$myobject = new java("myclass");

3) store this in the java context so I can access this object again after
the script is renewed. For that I am trying this:

define("ENGINE_SCOPE", 100);
java_context()->setAttribute("myobject", $myobject, ENGINE_SCOPE);

4) and then getting the object out again in the new script with:

$myobject = java_values(java_context()->getAttribute("myobject"));


But trying to access the java context after I started up the bridge gives
me:

*Warning*: fread() [function.fread <http://localhost/mmic/function.fread>]:

C:\MyPrograms\wamp\www\mmic\java\Java.inc* on line *1157*

With the backend log stating:

   at php.java.bridge.http.HttpServer$Runner.run(HttpServer.java:205)
   at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:60)

So clearly this is not the way for me to accomplish what I want to
accomplish. So my question is, what would be the correct way to keep a java
object created in php from one php script execution to another?

Thanks a lot in advance for any insights, suggestions!
