我确信我已将相册放入我的包装中，但仍然存在此错误：

org.apache.jasper.JasperException：无法为JSP编译类

jsp文件中的第38行：/albums.jsp发生错误生成的servlet错误：相册无法解析为类型

jsp文件中的第38行：/albums.jsp发生错误生成的servlet错误：复制本地变量相册

当我重新启动tomcat服务时似乎没有用，谢谢你回答!!!

Answer 1

请看一下：

List<album> albumList = new ArrayList<album>();

专辑已在JSP中定义为bean。但是，在List定义中，您需要提供类名。

我相信您需要将此行更改为：

List<photoshare.Album> albumList = new ArrayList<photoshare.Album>();

jsp专辑可以解析为一种类型
