您好我正在使用 SWING 作为客户端、Java WebStart JNLP 和 Spring 在服务器端使用 HTTPInvoker 开发 RIA 应用程序。

当我尝试从 JNLP 启动并运行我的应用程序时，我收到以下错误消息。但是，如果我运行与 java 应用程序相同的应用程序，它可以正常工作并与服务器通信并使用 spring bean 获取数据。

我的 client.xml 文件位于客户端包中，由 jnlp 查看。

这是我的 JNLP 文件：

</jnlp>

相关的类（org.springframework.util.ReflectionUtils）存在于 sping-2.5.6.jar 和 spring-core.jar 中，我猜它会导致混淆。首先，我会删除 spring-core.jar，因为它包含在大 spring.jar 中。
