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"?> 
<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-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>

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.

  • Thanks for the link but read the comment on ZZ Coder's answer. Any ideas? –  Oct 07 '09 at 03:01
  • @Smithers: FYI: you can edit your question to contain a formatted error message, after the fact. Much better than comments. – Stu Thompson Oct 07 '09 at 08:20

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.

  • The JRE on my system is the latest version and is being pointed to by my JAVA_HOME environment variable. However, the Tomcat addon to xampp has a jre included in the installation and is using an old version. I ran tomcatw6.exe and tried to change it to point to the new JVM, but then I could no longer start tomcat. Any ideas? –  Oct 07 '09 at 02:59

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.
