下面是客户端调用时的方法（客户端现在不能修改只能改服务端）：/**
* 执行远程调用,单例模式调用
*
* @param url
* wsdl URL
* @param invokeFunc
* 调用方法
* @param objArray
* 参数
* @return
* @throws Exception
/
public static String remoteCall(String url, String invokeFunc,
Object... param) {
Client client = null;
ClientPool pool = ClientPool.getInstance(url);
LOGGER.debug("执行webservice使用参数：" + Arrays.toString(param));
LOGGER.debug("执行webservice调用方法：" + invokeFunc);
try {
client = pool.get();
if (null == client) {
return CONNECT_TIMED_OUT;
}
return executeRemoteCall4String(client, invokeFunc, param);
} catch (Exception e) {
LOGGER.error("执行webservice调用失败,尝试重新初始化客户端后调用", e);
pool.destory(client);
client = pool.get();
try {
return executeRemoteCall4String(client, invokeFunc, param);
} catch (Exception e1) {
LOGGER.error("error ro invoke function: " + invokeFunc
+ ", where remote call url=" + url + " and params:"
+ Arrays.toString(param));
}
} finally {
pool.reuse(client);
}
return null;
}

/*
* 用指定客户端执行远程调用
*
* @param Client
* Client
* @param invokeFunc
* 调用方法
* @param objArray
* 参数
* @return
* @throws Exception
*/
private static String executeRemoteCall4String(Client client,
String invokeFunc, Object[] objArray) throws Exception {
if (client == null) {
return null;
}
Object[] results = client.invoke(invokeFunc, objArray);
if (results != null && results.length > 0) {
String resultStr = (String) results[0];
LOGGER.debug("执行webservice返回结果：" + resultStr);
return resultStr;
}
return null;
}

你这个得看服务端的方法吧
