Thanks Duong!

This almost entirely works.  I am only having an issue with the 
generated Type Id in the SWT custom transfer class.

Re:
>     protected static DataFlavor customFlavor = new DataFlavor
> (CustomClass.class,

and:

The problem is, in my Transfer class I have

    /*
     * Method declared on Transfer.
     */
    @Override
    protected int[] getTypeIds() {
        return new int[] { TYPEID };
    }

Unfortunately, when

ByteArrayTransfer:
abstract public boolean isSupportedType(TransferData transferData);


s being called, and trying to match TYPEID with the type (integer) that 
gets defined by customFlavor.. the numbers do not match.

So, in my Transfer class TYPEID = 50031, and in customFlavor (when it 
gets sent over the pipe to Transfer) the type = 49981.  (not exact 
numbers, but something like that).

If I manually change my custom Transfer:

    /*
     * Method declared on Transfer.
     */
    @Override
    protected int[] getTypeIds() {
        return new int[] { TYPEID, 49981 };
    }

then it will work.  

I would like to correctly have TYPEID programatically generated at run 
time, and it seems like I am just not passing the correct value for 
MYTYPENAME.  

Do I need MYTYPENAME to look something like, "Mime type/text... 
class=custom.class"?

With this resolved - I think I will be fully satisfied with the 
solution!

Thank you,
Sheldon
