我正在制作智能购物系统的Android应用程序。我想： -
制作一个可以创建产品信息QR码的网络应用程序（即具有唯一产品ID的QR码）。所有这些信息都应存储在MySQL
此QR码将包含类似的网址 http://localhost:8080/Mysupermarket/index.jsp/pid=1 （像这样）
客户将扫描二维码并转到此页面，并以某种方式获取该产品的数据库中的所有详细信息存储。
4.然后应将所有这些数据转换为字符串，以便我的应用可以转换为语音
到目前为止我做了什么？

我遵循本教程使用SOAP Web服务。但是当我在服务器上运行webapp并单击listservice时，它就抛出了这个异常

我该如何解决？ 另外，请提供一些关于如何将Android应用程序连接到Web服务的好教程。 他们中的大多数都使用PHP。我想使用Java。
提前致谢
答案 0 :(得分：0)
此错误看起来像构建路径问题。您必须向应用程序添加依赖项; 正确的依赖是;
<dependency>
<groupId>org.apache.ws.commons.schema</groupId>
<artifactId>XmlSchema</artifactId>
<version>1.3.2</version>
</dependency>
