one other question, can you tell me what files should be in java400/ext? I'd like to only have what "IBM" provided.

Not sure what you mean by "they are unpacked whether or not they are
used". JAR files aren't unpacked ever, unless you deliberately do so
with the "jar" command.

But when you store them in /QIBM/UserData/Java400/ext they are loaded
into memory with every Java program on the system. Not unpacked. Just
loaded into memory so they are ready to be used.

I wouldn't choose to unpack JAR files. There doesn't seem to be any
performance difference that I've found between keeping them in a JAR and
unzipping/unpacking them.

So, just to clarify, all the "jar" files located in
QIBM\UserData\Java400\ext are unpacked whether they are used or not by
the java app?

As Chris mentioned, is it better to unpack all jars for performance and
such?
