Java web 项目经常需要处理错误的情况，总不可能让服务器的错误就这么抛出来的，这样即不安全，也不美观，看下面例子

<%@ page contentType="text/html; charset=utf-8" language="java" import="java.util.*" errorPage="" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>ERROR</title></head><body><h3>ERROR PAGE</h3><!--======start: row 02======--><div id="row02" class="doc01"><table><tr><td align="left" valign="top">Error: </td><td style="width:20px;"></td><td align="left" class="h20"><%//--------------------------------------//active this code only for develop//--------------------------------------Throwable throwable = (Throwable) request.getAttribute("javax.servlet.error.exception");if(throwable == null){out.println("<b>4XX/5XX Erro:</b> <p>找不到指定的资源或请求的文件不存在。</p>");  }else{out.println("<b>4XX/5XX Error: </b> "+throwable);}out.print("<p>");if (throwable != null) {StackTraceElement[] stackTraceElements = throwable.getStackTrace();for (int i = 0; i < stackTraceElements.length; i++) {out.print(stackTraceElements[i].toString() + "<br>");}stackTraceElements = null;}out.print("</p>");throwable = null;%> </td></tr></table></div><!--======end: row 02======--><br><br><h4>page footer</h4></body></html>

整理一下，呵呵，懒人计划...
