Question

在jsp中使用iframe，iframe部分显示出来的是出错代码，无法正确显示

我在jsp页面中使用iframe嵌入一个页面
<div class="right">
<iframe src="Web/right.jsp" height="740px" width="355px" scrolling="no" frameborder="0" marginheight="0" marginwidth="0"></iframe>
</div>
在我的tomcat服务器中显示没问题，都可以正常显示，但是发布到网上就是iframe里面的页面无法正常显示
显示如下代码：

Answer 1

java.lang.NullPointerException
ystour.search.Search.getWay(Search.java:41)
org.apache.jsp.Web.right_jsp._jspService(right_jsp.java:154)

查处你的代码吧，应该是right.jsp或search.java的41行有一个空指针错误
