Maps are not typesafe.  While it is possible to get it to work, I don't
think you want to send a non-typesafe component over a webservice. It
would open the door to errors.  XML-RPC works the best when your types
are expiclity declared.  I would avoid anyType declarations.  Usually
they can be avoided.

Might I suggest you change your design and use an array of JavaBeans as
your "values" argument.

public class MyBean (

        private String key;
        private String value;

        // With your getters and setters below.

)

public MyObject serviceMethod(MyBean[] values) {
