如果把
删除，则启动不会报异常，请问，不删除这句，异常如何解决？
[b]问题补充：[/b]
工程还没有开始,测试就出现这个问题了!还有一个问题就是,从JSP向Action传中文,变乱码!
[b]问题补充：[/b]
就这行配置文件,没有什么其它的了哟@!

乱码的问题解决了
就在struts.xml加入这句就行了!
不过最开始的异常没有解决哦!
value=”GBK“换成UTF-8
我用你的代码试了下没什么问题..应该是你工程的问题
你把
constant name="struts.configuration.xml.reload" value="true"/>
删掉又有什么关系呢.
一般的大一点的项目 重新加载的都会报写异常.
我喜欢看你工程，不想看你异常，把你工程发上来我帮你看看
你的struts.xml文件配置没有多大 可能是其他的问题啊
还是多上传写配置文件
乱码简单 我传个过滤器给你
package com.mars.struts.filter;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
public class Filter implements javax.servlet.Filter {
public void destroy() {
// TODO Auto-generated method stub
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("utf-8");
chain.doFilter(request, response);
}
public void init(FilterConfig arg0) throws ServletException {
System.out.println("filter--------init?");
}
}
在web.xml配置文件中就写
filter
com.mars.struts.filter.Filter
filter
/*
把你的web.xml配置文件发上来看看
