html:errors不能显示错误内容

[quguilai]

struts阻止了进入主页面，可是错误的信息显示不出来
这到底是哪里出了错?

[quguilai]

再请各位问一下
要显示<html:errors>要有什么条件?
validation.xml一定要配置吗?

[逍遥小飞狼]

有没有在资源文件里写错误信息呢？

编码
怎么样编码?

[quguilai]

应该不要写吧
用底下这种方法
package register;
import studentmessage.*;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.*;
import java.sql.*;

public final class RegisterControl extends Action
{
private StudentMessage stumes=new StudentMessage();

// private String id;

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
StudentForm f=(StudentForm)form;
//request.setCharacterEncoding("iso-8859-1");
try
{
Register r=new Register();
//id=request.getParameter("IdentityCard");
// r.setIdentityCard(id);
r.writeSql(f.getstumes());
ActionMessages messages=new ActionMessages();
ActionMessage message=new ActionMessage("success","注册成功");
messages.add(ActionMessages.GLOBAL_MESSAGE,message);
saveMessages(request,messages);
request.setAttribute("StuMes",f.getstumes());
return(mapping.findForward("registersuccess"));
}
catch(Exception e)
{
ActionErrors errors=new ActionErrors();
ActionError error=new ActionError("error","对不起，由于系统或网络原因，您的注册没有成功");
errors.add(ActionErrors.GLOBAL_MESSAGE,error);
saveErrors(request,errors);
request.setAttribute("exception",e.getMessage());
request.setAttribute("id",stumes.getidentityCard());
return(mapping.findForward("registererror"));

}

}


}

我已经解决了
要写资源文件
谢谢

知道了就好，顺便告诉你一下:如果是中文的资源文件，要编码一下才可以显示
