Hi Luke,
This is working fine. I do have one more problem if you don't mind.
I need
to check the device or endpoint to see if it transmits or receives midi
data (notes,
channels, whatever) before I set it to my gui for the user to select as
an input or
output. I don't want the user selecting a device that can't receive
midi messages
for an output. Likewise, the same for input. I have tried
MidiDevice.getDevice(i).getStringProperty(MIDIConstants.kMIDIPropertyRec
eivesNotes)
with no result. I get a error message stating that I am using the
wrong property. Any
Idea to who to get a devices or endpoints properties?

For what you're doing, you'll probably want to look up the chain a

to get a string that would be interesting to the user.
If you have any interest in working in C, you can check out the
functions:
OSStatus MIDIEndpointGetEntity( MIDIEndpointRef inEndpoint,
MIDIEntityRef * outEntity);
And...
OSStatus MIDIEntityGetDevice( MIDIEntityRef inEntity,
MIDIDeviceRef
* outDevice);
And then get the name property for the device and/or entity, and use
that
string to name/label your endpoint.
In Java you should use the
Int MIDIDevice.getNumberOfDevices();
MIDIDevice MIDIDevice.getDevice(int index);
Methods, and traverse the hierarchy down through entities and
endpoints to
then match up your source/destination endpoints with their parent
devices
and those properties.
