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  
<a href=<%=request.getContextPath()+"/forum/new.jsp" %>>反馈</a>  
提醒我... 或者  
<a href="javascript:history.go(-1)">返回上一页</a>  
<hr width=80%>  
<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();

}  
%>

<%=request.getAttribute("javax.servlet.forward.servlet_path") %>  
 
<p>With the following stack trace:</p>  
<pre>  
<%exception.printStackTrace();  
      ByteArrayOutputStream ostr = new ByteArrayOutputStream();  
      exception.printStackTrace(new PrintStream(ostr));  
      out.print(ostr);  
    %>
