java调用webservice-知了堂

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。

Access restriction on class due to restriction on required library rt.jar? 报错

java调用webservice

    怎么都感觉是环境问题,系统bug。解决如下:

    进入project properties的 Build Path 设置里.
    移除 JRE System Library
    再添加回来,方法是: 选择 “Add Library” ,然后选择 JRE System Library.
