Excellent. That was exactly what I was looking for. One more request.
Where might I find the collection of "import" statements for a generated
class? I need to replicate a few of them in the interface. Thanks
again.
Dan
PS - It's a bad abbreviation, but "w/" is short for "with". So "w/a"
means "with a" (and "w/o" means "with out").

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.
