The dll (or java.so) is obsolete. We'll keep it, but you have to compile the C code yourself.

I have updated the FAQ:

-------------
Do I have to require Java.inc in each of my scripts? Isn't that very slow?

In order to communicate with Java, a PHP "Java" class definition is needed. Here's a simple PHP
"Java" class definition which fits into one line:

    <?php
    // The following is the "Java" class definition, stripped down to fit into one line
    // To use this sample start Java with: java -jar JavaBridge.jar INET:9267
    // Or enable java.so or php_java.dll, which automatically start the above
    // process Then type: php sample.php
    //
    class P {const Pc="<C v=\"%s\" p=\"I\">", PC="</C>"; const Pi="<I v=\"%d\" m=\"%s\" p=\"I\">",
PI="</I>"; const Ps="<S v=\"%s\"/>", Pl="<L v=\"%d\" p=\"%s\"/>", Po="<O v=\"%d\"/>"; private $c;
function str($s){fwrite($this->c, sprintf(self::Ps, $s));} function obj($s){fwrite($this->c,
sprintf(self::Po, $s->java));} function __construct(){$this->c=fsockopen("127.0.0.1",9267);}
function cBeg($s){fwrite($this->c, sprintf(self::Pc, $s));} function cEnd(){fwrite($this->c,
self::PC);} function iBeg($o, $m){fwrite($this->c, sprintf(self::Pi, $o, $m));} function
iEnd(){fwrite($this->c, self::PI);} function val($s){if(is_object($s))$this->obj($s);else
$this->str((string)$s);} function res(){$r=sscanf(fread($this->c, 8192),"%s v=\"%[^\"]\"");return
$r[1];}} class Java {var $java, $p; function __construct() {if(!func_num_args()) return;
$this->p=new P(); $ar=func_get_args(); $this->p->cBeg(array_shift($ar)); foreach($ar as $arg)
$this->p->val($arg); $this->p->cEnd(); $ar = sscanf($this->p->res(), "%d"); $this->java=$ar[0];}
function __call($meth, $args) {$this->p->iBeg($this->java, $meth); foreach($args as $arg)
$this->p->val($arg); $this->p->iEnd(); $proxy = new Java(); $ar = sscanf($this->p->res(), "%d");
$proxy->java=$ar[0]; $proxy->p=$this->p; return $proxy;} function toString() {$this->p->iBeg("",
"castToString"); $this->p->val($this); $this->p->iEnd(); return base64_decode($this->p->res());}}

    // Test
    $i1 = new Java("java.math.BigInteger", "1");
    $i2 = new Java("java.math.BigInteger", "2");
    $i3 = $i1->add($i2);
    echo $i3->toString() . "\n";

    ?>

The above simple "Java" class assumes that some Java VM has been started on host "127.0.0.1", port
"9267". And it cannot handle values larger than 8192 bytes. Therefore the PHP/Java Bridge library
Java.inc should be used. Scripts should contain the statement

      require_once("...java/Java.inc"); 

at the beginning of each script. PHP compiles and caches PHP scripts, the Java.inc library is
loaded only once.

Hi Antonio,

yes, I've committed the change to the CVS (for release 5.2.1).

Thank you very much for reporting this!

Hi,

your logger definition may be incomplete. Please see our FAQ and the log4j classes from the
JavaBridge for details.

However, logging is outside of the scope of the PHP/Java Bridge. :)
