このコードを実行すると、NullPointerException. いつも来るわけではありません。2つのバージョンを試しましたが、同じ例外があります。
ExchangeService service = new ExchangeService();
バージョン 1:
port = service.getExchangeServicePort();
バージョン 2:
port = service.getPort(new QName("http://schemas.microsoft.com/exchange/services/2006/messages","ExchangeServicePort"),ExchangeServicePortType.class);
例外：
java.lang.NullPointerException
