Question

我想阅读Outlook日历。所以我开始尝试连接到服务器。我找到了http://code.msdn.microsoft.com/exchange-ews-java-api-12-1a5a1143，只想获得连接并尝试一下。

我找到了一个例子并尝试了这个：

import microsoft.exchange.webservices.data.*;
...
public void test(){     
    ExchangeService es = new ExchangeService();
    ExchangeCredentials credentials = new WebCredentials("user", "Password");
}

Exchange服务崩溃了：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/httpclient/HttpConnectionManager
at ExchangeTest.test(ExchangeTest.java:15)
at Window.main(Window.java:19)

我试图导入一个库，但没有得到正确的，否则错误是其他的。你能告诉我我需要哪个库，或者我在哪里/如何修复它。感谢。

我正在使用Win7。
