java调用webservice
有一些已有的webservice服务，由xfire生成发布，有些有参数，有些无参数，无参数的直接我直接使用org.codehaus.xfire这个包里的Client来动态生成客户端。然后调用就可以了。非常简单
Client client = null;
try {
client = new Client(
new URL(
“http://leaver.me/testService?wsdl“));
client.invoke(“refreshAllCache”, new Object[0]);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}</pre>
但对于有参的，且是服务器自定义的类作为参数的时候，实在是搞不定。。不管是把自定义的类放到本地，包名一致，在invoke的时候生成这个对象还是其他什么方法。都无法完成。
最终换了直接发送soap报文来完成。dirty hack啊。如果你有一些好的方法希望不吝赐教。
解决方案来源自stackoverflow，因为stackoverflow现在国内好像有时候打不开。因此把代码贴过来。有疑问的话留言讨论。
