Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. Because of this, we hope you add your comments
to the existing bug instead.
Thank you for your interest in PHP.

hi all,
i just installed all the latest versions (php 4.3.2) and various forms
of the j2sdk (principally j2sdk 1.4.1_03) and i get the same problem.
Set up is Apache/1.3.27 (Win32) PHP/4.3.2 (on windows xp) php_java and
php_gd2 are the only extensions installed. Whenever i run a page with a
call to new Java() the first refresh works, but after roughly 30
seconds i must restart apache to get it to work.
has there been any updates on this? I am only experimenting with this
extension, but it would be a fantastic help if it worked reliably.
my java section of php.ini
[Java]
java.class.path = H:\php\php-4.3.2-Win32\extensions\php_java.jar
java.home = C:\j2sdk1.4.1_03
java.library = C:\j2sdk1.4.1_03\jre\bin\server\jvm.dll
java.library.path = H:\php\php-4.3.2-Win32\extensions\
i noticed somthing noone had looked into; i checked the mem usage of
apache.exe as i continually refreshed the (java) page, it climbed
steadily until it reached somthing like 15000K and then i got the
error, and with more refreshes the mem usage remained constant. however
after a while (as i ytped this) the mem usage climbed (with no
activity) by another 2000K where it is now static. i don't know if that
is useful, but it seems to me that its loaded a few too many JVMs and
not closed them.
kind regards

Getting the same bug. Running Win2k Server, IIS 5, php4.2.3,
jsdk1.4.1. I read a while back that running as a CGI would eliminate
the error so I tried that but the performance hit was too much to bear
since I only used java on one page. Did a little more searching and
came up with a little work around. Still not perfect but takes much
longer to crash.
$descriptorspec = array(
0 = array(pipe, r), // stdin is a pipe that the child will
read from
1 = array(pipe, w), // stdout is a pipe that the child will
write to
2 = array(file, /temp/error-output.txt, a), // stderr is a
file to write to
);
$process = proc_open(c:\\php\\cli\\php.exe, $descriptorspec,
$pipes);
if (is_resource($process))
{
// $pipes now looks like this:
// 0 = writeable handle connected to child stdin
// 1 = readable handle connected to child stdout
// Any error output will be appended to /tmp/error-output.txt
$size = fwrite($pipes[0], ? \$Login = new Java('CheckLogin'); echo
\$Login-CheckLogin(' . $username . ', ' . $password . '); ?);
if(!fclose($pipes[0]))
echo There was an error closing the pipe;
$result = fgets($pipes[1], $size + 1);
fclose($pipes[1]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close($process);
}
Basically what I do is create a process and send it the lines of code I
would use to create and manipulate the java classes. The process gives
me the output and I close the process. It works pretty well and will
extend the restart interval from everytime the script runs to every
couple of days.
For those out there chasing this bug, my method fails on the
$return_value = proc_close($process); line. Once it fails it will not
work again until IIS is restarted. Until IIS is restarted the process
fails on $result = fgets($pipes[1], $size + 1); line. Hope you get
this one fixed. This could be a really powerful plugin.

Why should it recreate JVM?
Since it's module, I think it need only create JVM once.
In linux environment, althoug i don't meet the error, the preformence
is bad when system recreate JVM.
How can i disable recreating the JVM or decrease the

I tried Java - PHP extension with just simple java class which is
doing millon calculations. I haven't got any problem. And I was
thinking to use this extension for my new web project but, after
reading all these bugs I am not sure. So, please let me know how stable
this is??

fclose($pipes[1]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close($process);
}
Basically what I do is create a process and send it the lines of code I
would use to create and manipulate the java classes. The process gives
me the output and I close the process. It works pretty well and will
extend the restart interval from everytime the script runs to every
couple of days.
For those out there chasing this bug, my method fails on the
$return_value = proc_close($process); line. Once it fails it will not
work again until IIS is restarted. Until IIS is restarted the process
fails on $result = fgets($pipes[1], $size + 1); line. Hope you get
this one fixed. This could be a really powerful plugin.

I meet this problem too.
Why should it recreate JVM?
Since it's module, I think it need only create JVM once.
In linux environment, althoug i don't meet the error, the preformence
is bad when system recreate JVM.
How can i disable recreating the JVM or decrease the frequence of
creating JVM?

Has anything been resolved for this usiong the non-cgi approach?
I have found something I did not see in other comments. It seems that
I get the fatal error after a set amount of seconds. Maybe due to some

Hi everybody,
I experience the problem of the Unable to create Java Virtual
Machine, on a Windows 2000, with easyphp, after some search, my
conclusion is that you couldn't use (for the moment) php as a module in
Apache, you must for that use it in cgi mode (I tried it and it work
fine, and change from module to cgi mode doesn't affect usage of PHP).
My configuration is :
Windows 2000
Apache 2.0.45
J2SDK 1.4.1_02
PHP 4.3.2 RC3
You must install J2SK, Apache, and then php (the tutorial indicate how
to install in cgi mode), you can go to the following adress for
installation (a very good tutorial) :
http://hotwired.lycos.com/webmonkey/00/44/index4a_page8.html?tw=programming
after that just configure you php.ini with the following values :
[Java]
extension=php_java.dll
java.home = C:\j2sdk1.4.1_02\jre\bin
java.library = C:\j2sdk1.4.1_02\jre\bin\server\jvm.dll

Comment by: jlondon at mcg dot edu
Reported By: nalves at equifax dot com dot br
Status: Open
Bug Type: Java related
Operating System: Windows 2000
PHP Version: 4.2.3
New Comment:
Getting the same bug. Running Win2k Server, IIS 5, php4.2.3,
jsdk1.4.1. I read a while back that running as a CGI would eliminate
the error so I tried that but the performance hit was too much to bear
since I only used java on one page. Did a little more searching and
came up with a little work around. Still not perfect but takes much
longer to crash.
$descriptorspec = array(
0 = array(pipe, r), // stdin is a pipe that the child will
read from
1 = array(pipe, w), // stdout is a pipe that the child will
write to
2 = array(file, /temp/error-output.txt, a), // stderr is a
file to write to
);
$process = proc_open(c:\\php\\cli\\php.exe, $descriptorspec,
$pipes);
if (is_resource($process))
{
// $pipes now looks like this:
// 0 = writeable handle connected to child stdin
// 1 = readable handle connected to child stdout
// Any error output will be appended to /tmp/error-output.txt
$size = fwrite($pipes[0], ? \$Login = new Java('CheckLogin'); echo
\$Login-CheckLogin(' . $username . ', ' . $password . '); ?);
if(!fclose($pipes[0]))
echo There was an error closing the pipe;
$result = fgets($pipes[1], $size + 1);
fclose($pipes[1]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close($process);

Whenever I try to use a java class I keep on getting this problem Unable to create Java Virtual Machine. Some people have sggested to use CGI version instead of SAPI. But I dont wanna use it for the reasons mentioned above. I am wondering, if there exist any patch which can eliminate this problem. Thanks, Sohel Merchant.

#18600 [Com]: Unable to create Java Virtual Machine
ID: 18600 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Java related Operating System: Windows 2000 PHP Version: 4.2.3 New Comment: 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...

#18600 [Com]: Unable to create Java Virtual Machine
ID: 18600 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: Java related Operating System: Windows 2000 PHP Version: 4.2.3 New Comment: I had the same bug but after having looking a lot, I find a solution. You just have to configure php as a cgi-bin instead of as a module and it works perfectly. Hoping it will help you to fix the bug in the module. Cédric.

[2002-10-31 08:51:16] [EMAIL PROTECTED] Yeah the only real issue I can see here is that this is a Windows specific issue. I've looked through the the DSP file, and read up on specific linking issues in Windows... everything looks right from the end of PHP. I'm guessing this can be one of (or possibly all of) these things: A) specific to a JVM version - in which case we'd need to find out which one works, and then update the specific hooks into PHP to use the newer versions. B) Windows not liking Java at all - not much we can do about that. C) specific to PHP alone - in which case someone with more Windows dev experience will have to take a look at this. As I don't see any real issue with the way we're linking and calling things (beyond the really resource intensive comments). [2002-10-31 07:44:50] [EMAIL PROTECTED] I found this problem using Apache 1.x on Win2k. PHP 4.2.3 causes the JVM create failure (although I couldn't get any access violations). Under IIS4 , the access violation causes some serious problems, albeit intermittently. I found that starting small with Java-inclusive scripts allowed some java work to be done (such as retrieving JVM versions, etc). However, when I started some more serious Java work with some custom classes I got both the JVM create failure and an access violation which crashed IIS. A reboot was necessary to bring IIS back up (Win2k wouldn't even let me force kill the process!!). I took a look at the latest snapshot posted below, but this caused an immediate crash in Apache upon starting the service. Any other suggestions? [2002-09-27 12:00:04] [EMAIL PROTECTED] 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?
