我一直在試圖創建一個能夠連接到網絡的Quickbooks連接器爲2012年的QuickBooks在Windows 7Web連接器錯誤「驗證失敗」
的實現是在節目指南明確說明的一個簡單的Web服務（http://developer.intuit.com/qbsdk-current/doc/pdf/qbwc_proguide.pdf ）。
在authenticate方法中，我一直收到與「Authentication Failed」和「Object reference not set to Object of instance」相同的錯誤。我首先使用Eclipse在java中創建了示例Web服務。
問題在於驗證方法。
我還打開Web連接器的VERBOSE模式。
下面是完整的日誌
