OK thanks. I also had to add the libibmaio.so to a directory in the
java.library.path which for some reason doesn't include normal libary
paths.

That is something very non-Java-esque; there must be some JNI going on
there.

So is that ibmlmao.jar or whatever represent part of the Java platform
itself, because that's where you said you had it before, which seems
like a bad idea, but maybe you have a good reason for it.

I don't quite understand what you are saying. The packge is IBM's
asynchronous I/O. It is a zip file with separate jar and libibmaio.so
(and libibmaio.dll for windows) files, along with some documentation.
When I printed out java.library.path I noticed it did not include any of
the normal system libraries, /lib, /usr/lib, etc. so I just copied into

It shouldn't. The 'java.library.path' is not for "normal system libraries".

one of the listed java library paths and it worked. That was after I
include the jar file in my project as you suggested earlier.

When I printed out the java.library.path it displayed:

/opt/jdk1.5.0_15/jre/lib/i386/server:/opt/jdk1.5.0_15/jre/lib/i386:/opt/jdk1.5.0_15/jre/../lib/i386:/usr/lib/xulrunner-addons

So did that answer your question?

My question was whether this IBM JAR is inherently part of the Java platform,
or if it's a regular library.

You had indicated that its location is /opt/jdk1.5.0_15/jre/lib/ibmaio.jar.
That directory, /opt/jdk1.5.0_15/jre/lib/, is for Java, not for third-party
libraries.

Since I am not familiar with that JAR as a part of Java, I questioned why it
is in that directory.
