Has cxf 2.2.2 support hashmap databinding?

[L. J.W]

Hi all,I am using cxf 2.2.2,in
sample/java_first_jaxws/HelloWorld.java,I found the comment:
  /* Map passing
     * JAXB also does not support Maps.  It handles Lists great, but Maps
are
     * not supported directly.  They also require use of a XmlAdapter to map
     * the maps into beans that JAXB can use.
     */
    @XmlJavaTypeAdapter(IntegerUserMapAdapter.class)
    Map<Integer, User> getUsers();

It seems map not supported by cxf or jaxb.

but I write my SEI like following:

public StudentInfo getStudentInfo(String studentId);

and StudentInfo.java like following:

.....

private Map  addressMap;

   public Map<String,Address> getAddressMap() {
        return addressMap;
    }
    public void setAddressMap(Map<String,Address> addressMap) {
        this.addressMap = addressMap;
    }

.....

then I publish above to web service.

and I find the map in StudentInfo can transfer from service provider to
service consumer.

so,I am confused whether cxf 2.2.2 support map databinding or not?

Thanks.
