请帮我看看错在哪

ongoing

我是想运行nutch,之前
bin/nutch测试成功
sh crawl urls -dir crawl.demo -depth 2 -threads 4 >& crawl.log 也成功了

配置 Tomcat (我的 tomcat 安装在 /usr/jakarta-tomcat-4.0.4) ，

[root@fc3 nutch]# rm -rf /usr/jakarta-tomcat-4.0.4/webapps/ROOT*
[root@fc3 nutch]# cp nutch*.war /usr/jakarta-tomcat-4.0.4/webapps/ROOT.war
[root@fc3 webapps]# cd /usr/jakarta-tomcat-4.0.4/webapps/
[root@fc3 webapps]# jar xvf ROOT.war
[root@fc3 webapps]# ../bin/catalina.sh start

然后在浏览器中输入 http://localhost:8080 结果如下：

Apache Tomcat/4.0.4 - HTTP Status 500 - Internal Server Error

type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.
