如何通過Web服務將Android應用程序與MySQL DB進行通信？

我正在爲智能購物系統製作Android應用程序。我想： -如何通過Web服務將Android應用程序與MySQL DB進行通信？

使Web應用程序，它可以創建有關的產品（具有產品獨特的ID即QR碼）信息的QR碼。所有這些信息應該存儲在MySQL
該QR代碼將包含一個URL像 http://localhost:8080/Mysupermarket/index.jsp/pid=1 （像這樣）
客戶將掃描QR碼和將被引導到這個頁面，不知何故，他應該獲取該產品在數據庫中的所有詳細信息存儲。

4.該數據應該然後轉換爲字符串，以便我的應用程序可以轉換爲語音

我有什麼迄今所做的？

我跟着這個教程，使用SOAP的Web服務。但是，當我在服務器上運行Web應用程序，然後單擊listservice，把它扔到這個異常

如何解決呢？也請建議一些關於如何將Android應用程序連接到Web服務的好教程。他們大多數都使用PHP。我想使用Java。

在此先感謝

此錯誤看起來是構建路徑問題。您必須添加對應用程序的依賴關係; 正確的依賴關係是;

<dependency> 
     <groupId>org.apache.ws.commons.schema</groupId> 
     <artifactId>XmlSchema</artifactId> 
     <version>1.3.2</version> 
    </dependency>

我做到了。但現在它顯示錯誤的服務，當我運行它 – sandy

我通過下載最新的模式2.2.1 – sandy
