 New Comment:

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?

I tested with 4.3.0 (dev), and I got almost the same errors. The
'access violation' message is still there, and after some reloads, I
could hang the IIS, and I had to restart it.

During these tests I couldn't get the 'unable to create java virtual
machime' message.

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-latest.zip

Updating version.

As I asked before though, can you test an "unstable" build of PHP, aka
the code we are considering to be PHP 4.3.0 at the URLs provided above?

As soon as I knew about version 4.2.3, I got it and tried to see if the
bug was fixed. Unfortunatelly, after few tests, I got the message 'PHP
has encountered an Access Violation at 77FCB2B9'. So far I couldn't get
the message 'Unable to create java virtual machine', but I didn't run a
lot of tests.

Also, after a few reloads at my test page, I couldn't get no more
results (the request seemed to return nothing at all!). Other php pages
that don't use the java lib still work fine.
