 New Comment:

just to add to the list of symptoms.

First time I run a script, I get 
Warning: Unknown list entry type in request shutdown (0) in Unknown on
line 0

when the script is ending. The next time I try to load the same script,
I get 

Fatal error: Unable to create Java Virtual Machine in
c:\web\qvc\reports\test.php on line 2

win2k, j2sdk1.4, php 4.2.3.
Does that help?

FYI have tried it now on another system under Apache 2 / Windows NT 4.

Exactly the same problem: runs for a limited time period then reports
"Unable to load virtual machine".

Made sure Sablotron is not running also.

One further comment - just tried is with JRE 1.3.0 - exactly the same
problem.

Experiencing very similar problems to the first posted here - looks
like some kind of timeout issue.

Running Windows XP, PHP 4.2.2, j2sdk1.4.0_02, Apache/1.3.26

Running the first sample PHP/Java script from the manual, PHP
successfully loads the Java Virtual machine straight after an Apache
restart. After that I can run the script as long as it was run in
roughly the last 30-60 seconds. If I wait longer that this time period,
the script can no longer load the JVM.

If you want to re-create the PHP environment, I'm using Firepages
phpdev5: http://www.firepages.com.au/dev5.htm

ini settings;

[Java]
java.class.path =
"c:\phpdev5\php\extensions\php_java.jar;c:\phpdev5\classes"
java.home = "C:\Programme\Java\j2sdk1.4.0_02\jre"
java.library =
"C:\Programme\Java\j2sdk1.4.0_02\jre\bin\server\jvm.dll"
java.library.path = "c:\phpdev5\php\extensions"

Yes, it's PHP. The message shown is similar to 'PHP has encountered an
Access Violation at 77FCB2B9'.

Well thats a good step, we got rid of one of the errors.  The access
violation though doesn't sound good.  Is it still PHP doing the
violation or is it the JDK?
