如何完善这段程序使之健壮?->关于 Cannot find bean list in any scope
JSP源代码如下:
<logic:iterate id="certificate" name="list" type="com.xindeco.business.graduatedata.CertificateVO"scope="request">
<td> <bean:write name="certificate" property="certificateName" scope="page"/></td>
</tr>
但是如果我在request.setAttribute ("list", certificateList) ; 中,certificateList是空值,则会出现如下的错误:
javax.servlet.jsp.JspException: Cannot find bean list in scope request
请各位大侠指教!
