This has been mentioned many times before, but I'd like to keep the issue fresh.  I have tried everything I can think of but still eventually end up with the infamous "Unable to create Java Virtual Machine" after a successful run of a few minutes.  It seems that if I keep clicking it will keep running, but if I let it idle for a while then I get the lovely notification.

This is using the pre-compiled .ZIP file (manual installation) with Apache 1.3.22.  I doubt this makes a difference as I have seen this issue coming up on Linux as well as Win2K IIS systems.  I've also observed Win98 people expressing the same behavior.

I would LOVE to use this Java bridge feature - please tell me if and how it can be done - my partner is suggesting we move away from PHP - give me some fuel to stop that from happening!!

Please do not forget  updating PHP version. Thanks.

I am really looking for a fix to this problem.  Just playing with INI file settings doesn't seem to cut it.  I have noticed that if you set KEEPALIVE to off in Apache you can only access Java once (otherwise as long as you refreshed the page every few seconds it would keep working).  I think this problem has something to do with what happens when the module is unloaded.  It might be ending up in an unusable but loaded state which prevents it from being loaded again.  It is obvious it is web server independant.

No, I have never been able to get this to work.  Maybe someone else can?

I am receiving the following error using Win2k / Apache1.3.22 / PHP4.1.2 / JDK1.2.2 -- Unable to initalize Java Virtual Machine -- immediately after loading a script that uses Java.  I can remedy the problem by restarting Apache, which is obviously not feasible.

Even i am facing the same problem.I am trying to call java from php.For this i am using PECL extension..and i also downloaded php java bridge.But the following test code:

$system = new Java('java.lang.System');	
// demonstrate property access
	echo "Java version=" . $system->getProperty('java.version') . "<br/>";

When i execute this i got the following error:
"Fatal error: java() [<a href=''></a>]: Unable to create Java Virtual Machine"

In php.ini i added the following thing:
java.home="F:\Program Files\Java\jdk1.6.0_03"
java.library="F:\Program Files\Java\jdk1.6.0_03\jre\bin\server\jvm.dll"

Then my system started give an error that "Apache HTTP Server has encountered a problem and needs to close.  We are sorry for the inconvenience."..And can anyone help me out to solve this problem?

If you use the PECL extension, report the bug there.

Please note that php 4.x will not get any non critical fix (security) until its very last release. Which PHP version do you use?

I am facing the same problem. Although it wortks fine on Windows, but it fails on linux. 
It fails only when it is being called through apache (web browser).
Else using php executable it passes. 
It fails on CreateJVM call.
