i found the following kinds of import statement.

for example, if A.java want to import the class B.C.D. but it write
the import statement like this:

import C.D;

which means B is omitted. the project is build by maven, does it
legal? why?

Where? Got an URL to this source*?

* (Or it's JavaDocs, build file..)

Sounds like complete rot to me. But then, I am not
confident that you are posting the correct details,
so (my suggestion is) try stopping using this 'A',
'B', 'C'.. rubbish and tell us the actual class/package
names involved.

It would violate sun naming conventions to call a class B.C.D.
see http://mindprod.com/jgloss/naming.html
and http://mindprod.com/jgloss/codingcoventions.html

You might call it b.c.D where b.c is the package name.

You might have a nested inner class with D inside C inside B. In that
case you just import the outermost class B.

In any case you just import the outermost class B.

I download the the project techus(http://svn.billen.dk/dk.teachus/
releases/teachus-1.9/) which is based on wicket framework(http://
wicket.sourceforge.net/).

for example, in the file TechUsApplication.java( under directory src
\main\java\dk\teachus\frontend),
it import class WebApplication like this:
import wicket.protocol.http.WebApplication; (line 16),

however the real package for this class(WebApplication) is :

org.apache.wicket.protocol.http.WebApplication;

it seems that org.apache has been omitted.

BTW: WebApplication is not an inner class.
