Question

我正在尝试打开JSP，但我遇到了错误。

HTTP状态500 - org.apache.jasper.JasperException：无法编译 JSP的类

var roleUserIdsQuery=from role in db.Roles 
                where role.Name=="User"
                from user in role.Users
                select user.UserId;
var users=db.Users.Where(u=>roleUserIdsQuery.Contains(u.Id)).ToList();

它在我的JSP中引用了这一行

    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

这是如何引起的？如何解决？

尝试删除';'从你的导入。我不确定你使用的服务器，但我发现这是tomcat版本7.057及更高版本。看看this
