Tomcat 6 - 请求的资源...不可用
我正在尝试开始使用 Java 和 Stripes Framework 进行开发。我的 web.xml 文件中有以下内容
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"

我收到错误:
The requested resource ... is not available.
是否有任何我需要添加的内容或我应该尝试修复与 tomcat 相关的内容。我使用了 xampp 的 tomcat 插件。我是初学者,所以这可能是一个简单的错误或跳过的步骤。我只是在寻找正确方向的推动力。

I am trying to start developing with Java and the Stripes Framework. I have the following in my web.xml file
<?xml version="1.0" encoding="ISO-8859-1"?>

I am receiving the error:
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.

该错误意味着您的 stripes 库是使用比 Tomcat 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。
请升级系统上的 JRE。
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.
Upgrade the JRE on your system.
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的目标编译器合规级别以及是否设置为 1.6 (Java 6);将其设置为 1.5(或服务器运行的任何 Java 版本)-重建并部署,看看会发生什么。
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.
