I've been spending some time with the mxj tutorial and looking at many

of the java examples, but I was wondering if there were any examples

of using multiple classes, package, or .jar files within Max? I

didn't see any, but I might have overlooked something. Tutorial09

I have a program that I have cobbled together in Java (still very noob

to Java) and now I am trying to convert it into a Max object in order

to use the data it collected within Max. My Java program uses a

couple of libraries and many external class files. The beginning of

It's all very messy right now and I'm trying to simplify...

main class that declares public static void main(String arg[]), you have 

a class that descends from MaxObject that provides an interface for 

communication with objects in your patcher. This also needs to be on the

Thanks for replying Owen. I've been getting some help off the list

from a Java pro. We got it working, but I may be having some thread

Thanks for replying Owen.  I've been getting some help off the list
from a Java pro.  We got it working, but I may be having some thread
and timing questions in the near future.

The only way I got this to work is to put both classes in a named package and import the external class into the class of the max object explicitly. So somehow Max doesn't search for class definitions inside the default package.

If you (or someone else) knows of an easier way, I'd love to know.

For a good reason. A max patch can contain several mxj/mxj~ objects, each loading classes from different projects or developers, all using the same JVM instance.

The default package is always evil. Personally I think it should be avoided in mxj alltogether, except maybe for the max entry-points (MaxObject descendants).
