客户端代码如下：

public class clientTest {
public static void main(String[] args) throws Exception {
clientTest test=new clientTest();
test.testClient();
}
public void testClient() throws Exception {
String serviceUrl = "http://10.3.59.17:9000/itsm/service/dbicDataInterface?wsdl";
Client client = new Client(new URL(serviceUrl));

HashMap map = new HashMap();
List ls = new ArrayList();
map.put("0", "123");
map.put("1", "456");
map.put("2", "789");
map.put("3", "0");
ls.add(0,map);
//调用特定的Web Service方法
Object[] i = client.invoke("setDbicDate",new Object[] { ls });

//int i = client.invoke("testWebService", ls);
System.out.println("result: " + i);
}
}
没有分可以给，希望高手们不吝赐教，小弟在此先谢过！！！

myeclipse中自带有xfire，在使用wsdl生成客户端时选择使用xfire生成，然后会有一个验证wsdl的，生成时如果不报错，就会成功。

这是xfire的局限性,xfire里涉及到复杂类型都要用JXAB转的.对于list来说,用泛型吧,泛型可以的.比如说一个User对象 . List<User> list=new ArrayList<User> 用这个list就可以通关
