An alternative solution (though probably not the one you want to use) is:
RealType X;
try {
X = new RealType("X",null,null);
} catch (TypeException e) {
X = RealType.getRealTypeByName("X");
}
Bill's solution is probably better for a server, since his code assumes
the variable already exists (which sounds like the more common case for
your application)
