php + java in winxp platform, reload dont work~

Dear all, i installed java jdk 1.4 and php 4.3.2 i tried to use java in php i edited the php.ini as follows [Java] extension=php_java.dll java.class.path = c:\php\extensions\php_java.jar java.home = C:\j2sdk1.4.1_01 java.library = C:\j2sdk1.4.1_01\jre\bin\server\jvm.dll java.library.path = c:\php\extensions and test it with following codes and it works (the code copy from php.net) <?php // get instance of Java class java.lang.System in PHP $system = new Java('java.lang.System'); // demonstrate property access print 'Java version='.$system->getProperty('java.version').' <br>'; print 'Java vendor=' .$system->getProperty('java.vendor').' <br>'; print 'OS='.$system->getProperty('os.name').' '. $system->getProperty('os.version').' on '. $system->getProperty('os.arch').' <br>'; // java.util.Date example $formatter = new Java('java.text.SimpleDateFormat', "EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz"); print $formatter->format(new Java('java.util.Date')); ?> however the problem is when i first run this page in IE, it works i click the reflesh button, it works but if i closed the IE, and load the page in a new broswer, it show "Fatal error: Unable to create Java Virtual Machine" i have to restart the apache server to get it work again, so what is going on?
