我似乎无法让 tomcat 编译它应该提供的 jsp 文件。它将完美地运行 .war 文件和 servlet。但是在任何jsp页面上都会失败。我得到的印象是它没有找到常规的 java 包含。

我正在尝试使用此文件(或包含的任何其他 jsp 测试文件)

<%@ page  language="java" import="java.util.*" errorPage="" %>
<html>
<body>
Current Date time: <%=new java.util.Date()%>
</body>
</html>


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

注意 Apache Tomcat/7.0.35 日志中提供了根本原因的完整堆栈跟踪。
