[antlr-interest] grammar that separates classpath from class name

I'm just starting with Antlr. I have past experience with JavaCC, but it's been a while.
I'm parsing a fully qualified java type name, and would like to differentiate the classpath from the class name. So if I were parsing this:
I would like to specify an expression for which the package and class name are distinct nodes in the parse tree. I copied a Java 5 grammar as a starting point, but that distinction is not made. I could easily do this separation in a visitor, but since Antlr is so cool, I'd rather that it did the work for me.
The catch is, I don't want to have the last dot character be part of the package name, and I don't want the dot to be part of the class name either.
So here is what I have so far:
genericTypeArgument : type | QUESTION_MARK (('extends' | 'super') type)?;
type : qualifiedJavaType arrayModifier* | primitiveType arrayModifier*;
packageDecl : (Identifier DOT)*;
qualifiedJavaType : packageDecl? javaType;
javaType : Identifier genericTypeArguments?;
This works almost. The package declaration includes the last dot. Is there a way that I can have the parser ignore(or not include) only the last dot in the package declaration?
