如何通过网络服务将Android应用程序与mysql DB进行通信



我正在为智能购物系统制作一个Android应用程序。我想：-

  1. 制作一个可以创建有关产品信息的二维码的网络应用程序（即具有产品唯一 ID 的二维码）。所有这些信息都应该存储在MySQL中

  2. 此二维码将包含一个类似 URLhttp://localhost:8080/Mysupermarket/index.jsp/pid=1（像这样）

  3. 客户将扫描二维码并被定向到此页面，并且他应该以某种方式获取该产品在数据库中的所有详细信息存储。

4.所有这些数据都应转换为字符串，以便我的应用程序可以转换为语音

到目前为止，我做了什么？

我遵循了本教程，它使用 SOAP Web 服务。但是当我在服务器上运行 web 应用程序并单击列表服务时，它抛出了此异常

我该如何解决？另外，请推荐一些有关如何将Android应用程序连接到Web服务的好教程。他们中的大多数都在使用PHP。我想使用Java。

提前致谢

此错误

看起来像构建路径问题。必须向应用程序添加依赖项;正确的依赖关系是;

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