codeModel.ref("com.acme.foo.MyNonExistingClass");
If the class does not exist (i.e. can't be loaded with Class.forName(...)) then
you'll get the JDirectClass instance, which is a valid JClass.
But since I guess you'll be actually _generating_ the interface with the code
model, just use the generate interface (this will be of the JDefinedClass).

Ehm... what's w/a?
Well, you can get a collection of methods from JDefinedClass (these are the
classes generated with this code model i.e. produced by JAXB):
myDefinedClass.methods()
will get you a collection of JMethod instances. JMethod has a number of further
public methods to give you name, param types etc.
If you wish, take a look at one of my plugins:
https://hyperjaxb3.dev.java.net/source/browse/hyperjaxb3/tools/src/main/java/org/jvnet/hyperjaxb3/plugin/
They'll get you clues to your questions.
Bye.
