[解决办法]
错误信息呢?
[解决办法]
错误代码呢
[解决办法]
Integer zhaopinListID = Integer.parseInt(request.getParameter("zhaoPinListID"));
zhaoPinListID这个属性哪儿来的，可能就是这个错，debug下。
[解决办法]
空指针
java.lang.NullPointerException
com.longxin.struts.action.zhaoPin.YingPinAction.execute(YingPinAction.java:65)
你看看YingPinAction.java 这文件的 65行
用DEBUG 跟踪下 看65行传了一个NULL进来了
