我有一个包含三个文件的 Java EE 项目delete.jsp，index.jsp并且BooksWorker.java.

在这里我无法运行index.jsp，即使我放置BooksWorker.class在 WEB-IN/classes 中。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



org.apache.jasper.JasperException: Unable to compile class for JSP:

尝试将BooksWorker类从未命名包移动到命名包。JSP 编译器无法访问 [未命名包] 中的类。

该错误很可能是由于未在 jsp 中导入 BooksWorker。

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