Great to hear you're making such good progress.  You can solve
your problem like this:
 
  RealType X = RealType.getRealTypeByName("X");
  if (X == null) X = new RealType("X",null,null);
 
Whether wisely or not, VisAD maintains a Vector of all RealTypes
constructed on a JVM and will not allow duplicate names [however,
duplicates can occur if a RealType of the same name is constructed
on another JVM and passed by copy (i.e., Serialized via RMI) to
this JVM].  RealType.getRealTypeByName will return any RealType
previously constructed on this JVM with a given name.
 
Good luck,
Bill
