只能导入一个类型.ABC 解析为一个包 [英] Only a type can be imported. ABC resolves to a package

问题描述

(我已经阅读了关于这个主题的其他问题，但没有一个有帮助)

(I've read other questions on this topic, but none of them have helped)

好的，我正在尝试将 Java 类导入到我的 JSP 文件中，但是 Tomcat 给了我错误:

Okay, I'm trying to import a Java class into my JSP file, but Tomcat gives me the error:

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

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

An error occurred at line: [16] in the generated java file: [I:path	oindex_jsp.java]
Only a type can be imported. org.runas.XKCDUtils resolves to a package

An error occurred at line: 7 in the jsp file: /index.jsp
XKCDUtils cannot be resolved

4:  String data = null;
5:  int finalComic = 1;
6:  int comicNo = 1;
7:  finalComic = XKCDUtils.getFinalComic();
8: 
9:  if (request.getParameter("page") != null)
10:         comicNo = Integer.parseInt(request.getParameter("page"));

我的JSP文件中的import语句是:

The import statement in my JSP file is:

<%@page import="java.io.*, java.net.*, org.runas.XKCDUtils" %>

我的目录结构的相关部分是:

The relevant section of my directory structure is:

webapps
`-ROOT
 `-index.jsp
 |-WEB-INF
  `-web.xml
  |-classes
   `-org
    `-runas
     `-XKCDUtils.class

我很困惑，因为 org.runas.XKCDUtils 解析为一个包，但它显然是一个类文件，在我认为是正确的目录中.

I'm confused because org.runas.XKCDUtils resolves to a package, and yet it is clearly a class file, in what I believe is the correct directory.

请帮忙！

(不要因为我使用脚本而责备我，我正在努力清理它们！)

(And don't chastise me for using scriptlets, I'm trying to clean them up!)

推荐答案

好吧，这很奇怪.我把导入分成三个导入，

Okay, this is weird. I split the import into three imports,

<%@page import="java.io.*" %>
<%@page import="java.net.*" %>
<%@page import="org.runas.XKCDUtils" %>

它神奇地决定工作.然后当我把导入改回来时，

and it magically decided to work. Then when I changed the imports back,

<%@page import="java.io.*, java.net.*, org.runas.XKCDUtils" %>

它神奇地决定继续工作.

it magically decided to keep working.

也许和重启Tomcat有关?好吧，无论如何它现在都有效.

Maybe it had something to do with restarting Tomcat? Well, it works now, anyway.
