（此处为示例代码。）
问题不是：

error: unreported exception XmlRpcException; must be caught or declared to be thrown

以至于 IDE ，这里， Netbeans ，不需要扔掉这个包裹。我希望将来会有一个选择 IDE 那就是 Exception 必须抓住或扔掉上面的东西。
在gui中没有这样的消息 Netbeans .
为什么不？

再说一遍，只关心 IDE 没有发现需要抛出异常。

进口货在grad尔。
项目属性：

我怎么才能得到 Netbeans 捡起 Apache 合适吗？
请注意，包的“自动导入”也不起作用。可能如果 Netbeans 如果进口所需的 Package ，另一个问题就会解决。
