UnsatisfiedLinkError When Executing FOP

[Joshua Brickner <jo...@rocketjones.com>]

I need to execute the following command in PHP to run FOP:

exec("/usr/local/src/fop-0.94/fop -xml billing_report.xml -xsl  
billing_report.xsl -pdf billing_report.pdf");

When I try it runs but the PDF is corrupted and I'm left with this  
error.

Exception in thread "main" java.lang.UnsatisfiedLinkError: /System/ 
Library/Frameworks/JavaVM.framework/Versions/1.5.0/Libraries/ 
libawt.jnilib:

The previous error is followed by a list of 49 messages that look like  
this (I can post the rest if it will help) :

at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1822)
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1723)
at java.lang.Runtime.loadLibrary0(Runtime.java:822)

When I run the exact same command in my CLI by hand it runs just fine  
and the PDF looks great. Any ideas of what the problem is?

Thanks,
Joshua Brickner

Seems to be a problem when accessing the Java native libraries in the  
PHP context. The first things to check: What are the permissions on  
the file/directory in question (should be -rwxr-xr-x for the file)?  
Does the user-account that is used in the exec() have the necessary  
privileges?


Cheers
