android 不能调用cxf服务

建了一个CXF服务，可以在tomcat7上跑.但android不能调用。代码如下:

IcxfWB .java
import javax.jws.WebService;
import javax.jws.WebParam;
import javax.jws.WebMethod;
@WebService
public inte易做图ce IcxfWB {
@WebMethod
String sayHello(@WebParam(name="name") String name);

}
================================
CxfWBImpl.java
public class CxfWBImpl     implements IcxfWB{
public String sayHello(String name) {
return "Hello "+name;
}

}
============================================
andorid代码如下:MainActivity.java

    }

    @Override

        return true;
    }


    @Override

        return super.onOptionsItemSelected(item);
