I am receiving the error:
我收到错误：
The requested resource ... is not available.
Is there anything I need to add or anything I should try to fix associated with tomcat. I used the tomcat addon to xampp. I am a beginner so it may have been a simple mistake or skipped step. I'm just looking for a nudge in the right direction.
有什么我需要添加的或我应该尝试修复与 tomcat 相关的任何内容。我在 xampp 上使用了 tomcat 插件。我是初学者，所以这可能是一个简单的错误或跳过了步骤。我只是在寻找正确方向的推动。

The error means your stripes library is compiled with a newer Java than the Tomcat's JVM. Java is not forward-compatible. Say your Tomcat runs under Java 5. It can't load classes compiled with Java 6.
该错误意味着您的条带库是使用比 Tomcat 的 JVM 更新的 Java 编译的。Java 不向前兼容。假设您的 Tomcat 在 Java 5 下运行。它无法加载使用 Java 6 编译的类。
Upgrade the JRE on your system.

I'm not sure but I think ZZ Coder could be right did you check what complier compliance level your project is targeted at and if it's set to 1.6 (Java 6); set it to 1.5 (or whatever Java version your Server is running in) -rebuild and deploy and see what happens.
我不确定，但我认为 ZZ Coder 可能是对的，您是否检查过您的项目针对的编译器合规性级别以及是否设置为 1.6（Java 6）；将其设置为 1.5（或您的服务器运行的任何 Java 版本）-重新构建和部署，看看会发生什么。
