Hi Lucas

I haven't used native methods with PL/Java before, so the best I can
offer is generic debugging... What makes you think it isn't
System.loadLibrary? Do you get a stack trace in the logs? Can we see the
relevant bits of your postgresql.conf? Did you add the path to the
library to LD_LIBRARY_PATH (or whatever the equivalent is on your platform)?

Cheers

Tom

More speculation here, but I thought that pl/java triggers/functions
couldn't access the disk, and maybe this is causing your library not
to load.

To do so you have to make them use the Java untrusted option. See

http://wiki.tada.se/display/pljava/Security

for more details (essentially just make the language javaU instead of
java and you can access the disk).
