我想把红线圈中的网页嵌入到500错误那里去
具体如下：
index.jsp中的代码：
jquery:$("#accountBtn").click(function(){ $.post("<%=basePath%>servlet/QuAccServlet",{},function(){ var account = document.getElementById("account"); account.src = "account.jsp"; });
iframe:<iframe width="100%" scrolling="auto" height="100%" frameborder="false" allowtransparency=true style="border: medium none;"id="account"></iframe>
account.jsp中的代码:<%List<Account> accounts=(List<Account>)request.getAttribute("accounts");%>//这句是从servlet传过来的值
我想通过集合遍历把属性值写入表格
<%for(Account account:accounts){ %> <tr> <td class="checkBox"><input name="" type="checkbox" value="" /></td> <td></td> <td><%=account.getAccName()%></td> </tr> <%}%>
可是只要account.jap中一加遍历代码，就报以下异常
<th width="">鎴愬憳缂栧佛</th>38: </thead>39: <tbody>40: <%for(Account account:accounts){41: %>42: <tr>43: <td class="checkBox"><input name="" type="checkbox" value="" /></td>Stacktrace:] with root causejava.lang.NullPointerException at org.apache.jsp.jsp.account_jsp._jspService(account_jsp.java:112) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:432) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334)
也就是图片上的500异常，我是想把account.jsp嵌入到index.jsp中，求高手帮小弟分析分析是哪出了问题，弄了一天了，就卡在了这里
