Answer 1

java.lang.NullPointerException
org.apache.jsp.VIP.TR.SR.TRSR55_jsp._jspService(TRSR55_jsp.java:71)在用到某個jsp頁面時有空指針這個是jsp文件名稱TRSR55VIP.TR.SR這個是它的路徑嗎

Answer 2

NullPointerException.
已经指出了，你看看你的代码中那个参数空指针，再看看。

Answer 3

他前面的路径是org.apche  是阿帕奇里带的吧   我怎么看怎么不舒服呢。。  这命名写的真压抑顺便小小得问一下 org.apache.jsp.VIP.TR.SR.TRSR55_jsp._jspService 这个不会是楼主自己定义的路径吧  那你可有才了！

Answer 4

楼主是否在jsp里写了java代码某段出了空指针异常、贴出来看看吧、

Answer 5

<%EiBlockMeta block = ei.getBlock("result").getBlockMeta();
Map map = block.getMetas();
Set<String> set = map.keySet();
%>
<tr>
<% 
for(String key:set){
EiColumn column = (EiColumn)map.get(key);
%>
<td><%=column.getDescName()%></td>
<% 
   }
%>

Answer 6

  EiBlockMeta block = ei.getBlock("result").getBlockMeta();
 应该是这句 获取不到值
