读文本文件常用方法，及在JSP中换行方法

JAVA中：
package com.action;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.connSql.DAOException;
import com.form.MonitorViewForm;


public class ReadTxtAction extends Action{

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws DAOException {

MonitorViewForm lf=(MonitorViewForm)form;

System.out.println("ReadTxtAction");
String findForward="";
/**
  * 读取txt数据
  */

    String url = "D:/mbfe.log";
   
    lf.setMefe(this.ReadDate(url));
   




findForward="sucess";



return mapping.findForward(findForward);
}

/**
* 读取txt数据
*/
public String ReadDate(String url) {
   try {
        FileReader read = new FileReader(new File(url));
        StringBuffer sb = new StringBuffer();
        char ch[] = new char[1024];
        int d = read.read(ch);
        while(d!=-1){
            String str = new String(ch,0,d);
           sb.append(str);
           d = read.read(ch);
         }
         System.out.print(sb.toString());
         read.close();
         return sb.toString().trim();
    } catch (FileNotFoundException e) {
         //e.printStackTrace();
         return null;
    } catch (IOException e) {
       //e.printStackTrace();
   return null;
    }
}

}



JSP中：
<pre><bean:write  name="monitorViewForm" property="mefe" /></pre>
