I need an urgent help from you people.I got something very odd while trying to integrate PHP with Java. First, my question: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 \[code\]"Fatal error: Unable to create Java Virtual Machine in C:\php\java.php ..."\[/code\]. 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.
My system specifications: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)
- 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.phpI placed the downloaded javabridge.jar file on this path: \[code\]C:\xampp\php\ext\\[/code\]Settings done in php.ini file for php-java integration are as follows.\[code\]; Directory in which the loadable extensions (modules) reside.extension_dir = "C:\xampp\php\ext\"I also uncomment the java extension.extension=php_java.dll\[/code\]I have added following lines in Module Settings section of PHP.ini file.\[code\];;;;;;;;;;;;;;;;;;;; Module Settings ;;;;;;;;;;;;;;;;;;;;[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.jarjava.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"\[/code\]
Java class which I am using in PHP script.\[code\]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; }}\[/code\]
PHP script test1.php which is using above java class \[code\]<?php// Format the HTML form.$salesTaxForm = <<<SalesTaxForm <form action="test1.php" method="post"> Price (ex. 42.56):<br> <input type="text" name="price" size="15" maxlength="15" value=""><br> Sales Tax rate (ex. 0.06):<br> <input type="text" name="tax" size="15" maxlength="15" value=""><br> <input type="submit" name="submit" value="http://stackoverflow.com/questions/3657785/Calculate!"> </form>SalesTaxForm;if (! isset($_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);}?>\[/code\]
