How to do PHP Java integration using phpjava bridge

[sandipkalal]

Hello Friends,
I need an urgent help from you people.
I got something very odd while trying to integrate php with java. First, my
system specifications:

Windows XP
I have installed
XAMPP server:- xampp-win32-1.6.1-installer
This install PHP, Apache, and MySQL on my system. There versions are as follows

Apache Version :- Apache/2.2.4 (Win32) DAV/2 mod_ssl/2.2.4 OpenSSL/0.9.8e mod_autoindex_color PHP/5.2.1
PHP version :- 4.3.1


Sun Microsystems JDK version :- jdk1.6.0_16


I am achieving this PHP-JAVA extensoion using php-javabridge. I have downloaded javabridge.jar file from following url.

http://php-java-bridge.sourceforge.net/pjb/download.php

I placed the downloaded javabridge.jar file on this path
C:\xampp\php\ext\

Settings done in php.ini file for php-java integration.


; Directory in which the loadable extensions (modules) reside.
extension_dir = "C:\xampp\php\ext\"

I also uncommented the java extension.

extension=php_java.dll

[Java]
;This points to the directory where your Java
;classes will be stored. You can designate multiple
;paths, each path separated by a semicolon.
;It must also include the location of php_java.jar
java.class.path = "C:\xampp\php\ext\JavaBridge.jar;C:\xampp\php\extensions\php_java.jar;C:\Program Files\Java\jdk1.6.0_16\jre\lib;C:\Program Files\Java\jdk1.6.0_16;C:\prog"

;java.class.path = "C:\xampp\php\extensions\php_java.jar;C:\prog"
; This points to the bin directory of the JDK.
java.home = "C:\Program Files\Java\jdk1.6.0_16\bin"

; This must point to the Java Virtual Machine (jvm.dll) file.
java.library = "C:\Program Files\Java\jdk1.6.0_16\jre\bin\server\jvm.dll"

; This must point to the location of php_java.dll.
java.library.path = "C:\xampp\php\ext;C:\Program Files\Java\jdk1.6.0_16\jre\lib"

java.java = "C:\Program Files\Java\jdk1.6.0_16\bin\javaw.exe"


Java class which we will going to use in PHP script.

import java.util.*;
import java.text.*;

public class SalesTax {

public String SalesTax(double price, double salesTax) {

double tax = price * salesTax;

NumberFormat numberFormatter;

numberFormatter = NumberFormat.getCurrencyInstance();
String priceOut = numberFormatter.format(price);
String taxOut = numberFormatter.format(tax);

numberFormatter = NumberFormat.getPercentInstance();
String salesTaxOut = numberFormatter.format(salesTax);

String str = "A sales Tax of " + salesTaxOut +
" on " + priceOut + " equals " + taxOut + ".";

return str;

}

}


PHP script test1.php which is using above java class


<?php

// Format the HTML form.
$salesTaxForm = <<<SalesTaxForm
<form action="test1.php" method="post">
Price (ex. 42.56):<br>
<input type="text" name="price" size="15" maxlength="15" value=""><br>
Sales Tax rate (ex. 0.06):<br>
<input type="text" name="tax" size="15" maxlength="15" value=""><br>
<input type="submit" name="submit" value="Calculate!">
</form>
SalesTaxForm;

if (! isset($_POST[submit])) :

echo $salesTaxForm;

else :

// Instantiate the SalesTax class.
$salesTax = new Java("SalesTax");

// Don't forget to typecast in order to
// conform with the Java method specifications.
$price = (double) $_POST[price];
$tax = (double) $_POST[tax];

print $salesTax->SalesTax($price, $tax);

endif;

?>


When I start the apache server service, the program runs ok. But, if I close the browser and open it again,
the program no longer runs and give me a
"Fatal error: Unable to create Java Virtual Machine in C:\php\java.php ...".

If I restart the apache server service, the program works again, but
with the same behavior: if I close the browser window and open it again,
it does not work.

I checked on internet but dont get any solution but found many people facing same problem.
And many of them told its a bug in PHP-JAVA bridge. So is there any solution on this problem.
I ran out of options and, if anyone could help, I'll appreciate.

Thank You.

this isn't really an xampp issues, but...
did you follow this: http://php-java-bridge.sourceforge.net/ ... lation.php
It looks like to me you need the Tomcat add-on for xampp.
