IIS "access denied" with php and java

I get this error when trying to run a simple php script:

Fatal error: Unable to load Java Library C:\j2sdk1.4.1\jre\bin\server, error: Access is denied. in c:\inetpub\wwwroot\php\java.php on line 3

So basically php is telling me that the server, in this case IIS 5.0 is not allowing access to C:\j2sdk1.4.1\jre\bin\server\jvm.dll.

I've tried web sharing on that directory but this isn't working. I'm afraid maybe I don't know enough about IIS management to solve this one. It seems like this kind of an issue to me.

fyi -- the php script causin the problem is:

PHP Code:


		
			
<?php



$systemInfo = new Java("java.lang.System");



print "Total seconds since January 1, 1970: 

".$systemInfo->currentTimeMillis();



?>

IIS at install creates a user IUSR_<machinename> that the webserver runs as. You need to provide this user access.

It's probably an NTFS issue, just highlight that dll and go to security, then allow the user as hedge wrote.

I actually found a solution this morning...this is taken from

http://php.networkedsystems.co.uk/m...kr/ref.java.php

######################################

** Success with W2K Server, PHP 4.3.0 as IIS5 SAPI module and J2SDK1.4.1_01 **

After a bunch of annoyingly spurious "access violation" and "Unable to create Java Virtual Machine" errors
I changed the php.ini setting for java.library from:

"C:\j2sdk1.4.1_01\jre\bin\client\jvm.dll"

to:

"C:\j2sdk1.4.1_01\jre\bin\server\jvm.dll"

All above examples now work perfectly incuding my own classes and those at
http://www.onlamp.com/pub/a/php/2001/06/14/php_jav.html (thanks to emilebosch above on 18-Oct-2001 07:19).

I'd really like to know the difference between 'client' and 'server' JVM versions if anyone can illuminate us.

Notes:

1. Manual install of PHP 4.3.0 to C:\php with the following relevant extracts from php.ini:

extension=php_java.dll
[Java]
java.class.path = "C:\php\extensions\php_java.jar;C:\java\packages\"
java.home = "C:\j2sdk1.4.1_01\bin"
java.library = "C:\j2sdk1.4.1_01\jre\bin\server\jvm.dll"
java.library.path = "C:\php\extensions"

2. Default installation of latest Java SDK from Sun

3. Win2K Server SP2 with all(?) patches

4. My own classes are placed in C:\java\packages\

Hope this helps some people.

Regards

-Neil

Thanks Neil. Well, it looks like it might not necessarily have been a server issue.
