Question

我有一个Java EE项目，其中包含三个文件delete.jsp，index.jsp和BooksWorker.java。

即使我将index.jsp放在WEB-IN / classes中，我也无法运行BooksWorker.class。我得到的错误：


type Exception report

message Unable to compile class for JSP:

description The server encountered an internal error that prevented it from fulfilling this request.

exception

Answer 1

尝试将BooksWorker课程从unnamed package移至named package。 JSP编译器无法从[未命名的包]中访问类。

Answer 2

最有可能的错误是由于没有在jsp中导入BooksWorker。

<%@page import="<package name>.BooksWorker"%>

无法为JSP编译类：BooksWorker无法解析
