启动Tomcat之后，在地址栏输入http://127.0.0.1:9090/umv报如下错误

用sysdeo tomcat插件从eclipse里面启动会出现乱码,但是tomcat/bin目录下直接启动没有这样的问题

EUC_CN 这个编码是java扩展才会有的,默认的jdk是没有这种编码的,你需要去下一个charsets.jar才会支持这个编码,默认的编码处理在rt.jar这个包里.
http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html
这个里面有java支持的编码.
你现在要么去下一个charsets.jar包,要么更改编码.
