程序发生了错误，有可能该页面正在调试或者是设计上的缺陷.

你可以选择

提醒我... 或者

<a href="javascript:history.go(-1)">返回上一页</a>

<h2><font color=#DB1260>JSP Error Page</font></h2>

<p>An exception was thrown: <b> <%=exception.getClass()%>:<%=exception.getMessage()%></b></p>

System.out.println("Header....");

Enumeration<String> e = request.getHeaderNames();

String key;

while(e.hasMoreElements()){

key = e.nextElement();

System.out.println(key+"="+request.getHeader(key));

}

System.out.println("Attribute....");

e = request.getAttributeNames();

while(e.hasMoreElements()){

key = e.nextElement();

System.out.println(key+"="+request.getAttribute(key));

}

System.out.println("arameter....");

e = request.getParameterNames();

while(e.hasMoreElements()){

key = e.nextElement();

System.out.println(key+"="+request.getParameter(key));

}
