、Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions
java.util.Map is an interface, and JAXB can't handle interfaces.
        this problem is related to the following location:
                at java.util.Map
                at private java.util.Map com.cecltd.service.jaxws_asm.SayHi.arg0
                at com.cecltd.service.jaxws_asm.SayHi
java.util.Map does not have a no-arg default constructor.         this problem is related to the following location:
                at java.util.Map
                at private java.util.Map com.cecltd.service.jaxws_asm.SayHi.arg0
                at com.cecltd.service.jaxws_asm.SayHi
解决方法：将服务端的services接口返回的Map类型的值，改成HashMap.
结论：在做webServices复杂类型值传递时，返回值的类型不要用接口类型。例如(List应该改为ArrayList,Map改为HashMap等)
