The results of printing System.getProperty("java.library.path") in the
jsp does show the correct path to my shared object....
Looking forward to your results with JSP.

I'm not doing a System.loadLibrary. The library is needed by a
third-party jar that I am using. SInce it works from within Eclipse I
know that their jar and the shared object (.so file) work correctly
together and that the shared object is indeed in the correct location on
library path. Its only when I deploy to the production version of
Tomcat (on the same machine) that this stuff fails. At that point I
don't have Eclipse's VM parameter setting abilities available to me and
the only place to put it is in JAVA_OPTS. From the tomcat log file I
can see that the java.library.path is set as intended.
I'll try your JSP idea just to be 100% the path is set correctly.

Thanks. I didn't literally mean X. The library it won't load is
called Netica. I just changed it to X to be more general. I hope
I'm not just creating confusion for everyone.
thanks

I believe there is a

or something like that, so that it doesn't try to load your X

Using Tomcat 5.5 on Linux.
I've set my environment variable with export
JAVA_OPTS='-Djava.library.path=/path/to/my/sharedobjectfolder'
After restarting tomcat and hitting my servlet (which depends on
the .so file in the folder above) I get an UnsatisfiedLinkError no
X found in java.library.path
I've looked in catalina.out and see a message that says that The
Apache Tomcat Native library cannot be found on java.library.path:
/path/to/my/sharedobjectfolder. So it appears that Tomcat is
using the path at least when it starts up. I've seen other Linux
Tomcat users raising this same problem and not getting any
answers. Within Eclipse I can run Tomcat and configure a VM
parameter for java.library.path and my library is successfully
found when the servlet runs so this issue only pertains to running
tomcat directly from the startup scripts (e.g. /etc/init.d/tomcat
start)
What could be wrong?
