【问题描述】：
我正在尝试使用 Apache CXF 框架在 Eclipse 中生成 Web 服务。 首先，我创建与所需 Web 服务对应的 Java 类，然后生成两个动态 Web 项目，一个用于 Web 服务（wsdl 文件），另一个用于客户端。 Web Web 服务在我创建后运行良好，但一段时间后（一到三天），我在服务器启动时收到错误显示在图像中。

然后，当我尝试从项目中调用 Web 服务时，我收到以下错误：

什么会导致这个只有在重复使用Web服务后才会出现的错误？

您好，客户端自动生成方式如下：
private static final QName SERVICE_NAME = new QName("http://read_variable/", "ReadVariableNodeServiceService");
URL wsdlURL = ReadVariableNodeServiceService.WSDL_LOCATION;
ReadVariableNodeServiceService ss = new ReadVariableNodeServiceService(wsdlURL, SERVICE_NAME);
SEIReadValue port = ss.getReadVariableNodeServicePort();
{
System.out.println("Invoking getValue...");
java.lang.String _getValue_arg0 = "Alina";
java.lang.String _getValue_arg1 = "WorkspaceS1";
try {
double _getValue__return = port.getValue(_getValue_arg0, _getValue_arg1);
System.out.println("getValue.result=" + _getValue__return);
................
上周我发现了一个有趣的文档，它推荐了以下调用 Web 服务的方法：
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(new String[]{"read_variable/client3_beans.xml"});
SEIReadValue port = (SEIReadValue) context.getBean("readvariableClient");
{
System.out.println("Invoking getValue...");
java.lang.String _getValue_arg0 = "Alina";
java.lang.String _getValue_arg1 = "WorkspaceS1";
try {
double _getValue__return = port.getValue(_getValue_arg0, _getValue_arg1);
System.out.println("getValue.result=" + _getValue__return);
.........
你怎么看？这可能是我出错的原因吗？
我很高兴我几乎找到了错误的原因。但是我是网络服务的初学者，我还没有完全理解你的信息。 我想指定我有一组基本/简单的 Web 服务，然后基于这些 Web 服务，我创建了一个复杂的 Web 服务，我在其中获取上下文 每个简单的 Web 服务以获取其功能，正如您所说（据我所知），这不是正确的方法。
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext(new String[]{"write_a_matrix/client2_beans.xml"});
SEIWriteMatrix port = (SEIWriteMatrix) context.getBean("write_a_matrix_Client");
...........................................................
ClassPathXmlApplicationContext context_WV=new ClassPathXmlApplicationContext(new String[]{"write_value/client1_beans.xml"});
SEIWriteValue port_WV = (SEIWriteValue) context_WV.getBean("write_a_value_Client");
...........................................................
我为每个 Web 服务客户端创建了一个 client_beans xml 文件。可以吗？您能否提供一个示例，说明如何调用 Web 服务以及如何只保存一个 App 上下文？
我会为您提供我的电子邮件地址 以防您想更轻松地交流，因为我已经看到我们被限制在一定数量的字符（对于 添加评论 部分）。
非常感谢！
