How to call jar files from PHP?
<p>I know this question is not new but I am posting this after going through enough googling around.</p>

<p>I have a jar file which I don't control. I mean I have not written the Java class in there and all I know is that there is a class named "hist" in it which takes two arrays and gives out the output. Now I have to use PHP to call this class "hist" in the jar file named "histvol.jar". I have installed the PHP/Java Bridge and it is installed correctly.<br>
But I don't understand how to call this jar file in PHP and where to place this jar file.</p>

<p>This is what I did:</p>

<ol>
<li>Installed tomcat and php-javabridge</li>
<li>Placed the jarfile "histvol.jar" under Tomcat/webapps/JavaBridgeTemplate621/webinf/lib/</li>
<li>Went to xampp/htdocs and created a file named testjava.php</li>
</ol>

<p></p>

<pre><code>&lt;?php  
require_once("http://localhost:8080/JavaBridgeTemplate621/java/Java.inc");  
$System = java("java.lang.System");  
$myclass=java("histvol");  
echo $System-&gt;getProperties();  
?&gt;
</code></pre>

<p><code>Class not found</code> exception is expected because I am not calling it anywhere in PHP, but how do I call it?<br>
I am lost, please help (I don't know a word of Java).</p>
