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

I am going crazy with this.  Any help would be greatly appreciated.

I just can't seem to understand how to communicate to java classes  
via PHP.  I know very little about Java, so am just trying to get the  
basics working before I go further with my project.  I'm sure this is  
ridiculously easy for you Java folks, but I am very confused - I must  
be going about this the wrong way:

I compiled a java class into a file called "HelloWorld.jar":

import java.util.*;
public class HelloWorld {
     public static void main (String args[]) {
         // insert code here...
         System.out.println("What up dog!");
     }
}

Then I created a PHP script to try and make a call to this using the  
PHP/Java bridge:

<?php
require_once('php_Java.php');
$dir = dirname($_SERVER['SCRIPT_FILENAME']);
java_require($dir."/HelloWorld.jar");

$x = new JavaClass("HelloWorld");
$y = new java_class("HelloWorld");
$z = new java("HelloWorld");
echo "=== CAST AS STRING ===<br/>";
echo (string)$x."<br/>";
echo (string)$y."<br/>";
echo (string)$z."<br/>";
echo "=== JAVA VALUES ===<br/>";
echo (java_values($x))."<br/>";
echo java_values($y)."<br/>";
echo (java_values($z))."<br/>";
echo "<p>-- END --";
?>

And when I fire this up in Safari to look at the results, I get:

=== CAST AS STRING ==
class HelloWorld
class HelloWorld
HelloWorld@aed5f9
=== JAVA VALUES ===
class HelloWorld
class HelloWorld
HelloWorld@aed5f9
-- END --

Why doesn't this thing print out my text.  What the heck am I doing  
wrong?  Any help appreciated.

Hi all,

First off, my knowledge of Java is very limited (thus the need for  
the PHP/Java bridge).

I have compiled and successfully installed the bridge for PHP 5.1.6  
for Mac OS X and wanted to install the PEAR class that represents a  
sample java class I have called HelloData (which simply prints "Hello  
the date is: mm/dd/yyyy").  I used the following command as per the  
instructions:

[PROMPT] sudo java -jar /usr/local/php5/lib/php/extensions/no-debug- 
non-zts-20050922/JavaBridge.jar --convert /usr/local/php5/lib/php  
HelloDate.jar

This ran for about 4 minutes before completing.  I was astonished  
that it would take so long.  After it completed I looked in the PEAR  
directory (/urs/local/php5/lib/php) and found several new directories:

drwxr-xr-x      5 root  wheel     170 Sep 10 14:19 HelloDate
drwxr-xr-x    416 root  wheel   14144 Sep 10 14:19 charsets
drwxr-xr-x   9200 root  wheel  312800 Sep 10 14:19 classes
drwxr-xr-x     46 root  wheel    1564 Sep 10 14:19 jce
drwxr-xr-x     82 root  wheel    2788 Sep 10 14:19 jsse
drwxr-xr-x    119 root  wheel    4046 Sep 10 14:19 laf
drwxr-xr-x    106 root  wheel    3604 Sep 10 14:19 ui

The first extra item makes sense, since it is the Java class I asked  
to be created in that command.  But the rest are a mystery to me  
(isse?  laf?  ui?).  And the "classes" directory is HUGE.  It looks  
like it has thousands of items (are these classes too)?

My questions are:
1) What are all those other directories for when I only asked for my  
sample class to be made into a PEAR class?

Thanks for the assistance.
