 New Comment:

I get the same problem.
My envirnment:
W2K Server
php4-win32-STABLE-200304180830
Apache 2.0.43
Jdk1.3.1 or j2sdk1.4.1_01
Module not CGI

If it can't be fixed quickly, how can I work around it?

Does this bug also exist in other platform,eg linux, solaris?

I get the same problem; The way I reproduced it is:

1. load a page with a Java call;
2. press and hold the refresh button.
3. It will eventually fail.

It seems that PHP is attempting to create a new JVM for each request
(unfortunately, this is required for a cgi install; it shouldn't be for
a SAPI install). My guess is that either Apache or PHP runs into
resource limits (e.g. does not release the JVM after it completes the
request; creates too many threads; etc...).

It would probably be better if PHP used a JVM pool; this wouldn't make
much difference in a cgi install, but would help SAPI installs. I have
no idea whether this is feasible or not; I've never actually taken the
time to give the source a looksy...

THANKS TO Alberto.Sarini@libero.it ,
The solution to resolve "Unable to Create Java Virtual
Machine" is to configure APACHE or IIS not using sapi for php but CGI

THANKS THANKS THANKS

go there for configuration

Hi there,

I'm confirming Cédric's knowledge - java is running correctly from
within PHP on Apache only when PHP is running as a CGI and not as a
SAPI module. When running PHP as Apache SAPI Module after the restart
Apache only fist access to php page using java is running OK, all next
reloads of this page caused "Fatal error: Unable to create Java Virtual
Machine in ..."
I think this could be still not solved bug.

Thanks
Alberto

BTW I'm running on:
OS:Win2000 Server SP2
Apache:1.3.27
PHP Version 4.3.0-dev (Build Date  Dec 12 2002 10:14:28)
Java version=1.4.1_01 
Java vendor=Sun Microsystems Inc.
