Tomcat 6 - 请求的资源...不可用

Question

我正在尝试使用Java和Stripes Framework开始开发.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"
    >

      <filter>
        <filter-name>StripesFilter</filter-name>
        <filter-class>net.sourceforge.stripes.controller.StripesFilter</filter-class>
        <init-param>
          <param-name>ActionResolver.Packages</param-name>
          <param-value>
            pdapm.action
          </param-value>
        </init-param>
        <init-param>
          <param-name>Extension.Packages</param-name>
          <param-value>
            pdapm.extensions, org.stripesbook.reload.extensions
          </param-value>
        </init-param>   
      </filter>

      <filter>
        <filter-name>DynamicMappingFilter</filter-name>
        <filter-class>net.sourceforge.stripes.controller.DynamicMappingFilter</filter-class> 
      </filter>

      <filter-mapping>
        <filter-name>DynamicMappingFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>   
      </filter-mapping>

      <welcome-file-list>
        <welcome-file>index.html</welcome-file> 
      </welcome-file-list>

</web-app>

我收到错误:

The requested resource ... is not available.

有什么我需要添加或我应该尝试修复与tomcat相关联的任何东西.我使用tomcat插件来xampp.我是初学者,所以这可能是一个简单的错误或跳过步骤.我只是想朝着正确的方向努力.

该错误意味着您的条带库使用比Tomcat的JVM更新的Java进行编译.Java不是向前兼容的.假设您的Tomcat在Java 5下运行.它无法加载使用Java 6编译的类.

升级系统上的JRE.
