lucene之Highlighter报错cannot be resolved to a type？

Question

页面顶部引入了：<%@ page import = " javax.servlet.*, javax.servlet.http.*, java.io.*, org.apache.lucene.analysis.*, org.apache.lucene.analysis.standard.StandardAnalyzer, org.apache.lucene.document.*, org.apache.lucene.index.*, org.apache.lucene.store.*, org.apache.lucene.search.*, org.apache.lucene.search.highlight.*, org.apache.lucene.queryParser.*, org.apache.lucene.demo.*, org.apache.lucene.demo.html.Entities, java.net.URLEncoder, org.apache.lucene.util.Version" %>==================================定义:Highlighter hl;//或者org.apache.lucene.search.highlight.Highlighter hl;==================================报错：org.apache.jasper.JasperException: Unable to compile class for JSP:An error occurred at line: 97 in the jsp file: /results.jsporg.apache.lucene.search.highlight.Highlighter cannot be resolved to a type仍然不行啊。

这个包不包括在lucene核心包lucene-core.jar里，你要下载全包，然后在contrib\highlighter找到这个包加上去，既然你把这些代码放到web上去，你要把这个包放到tomcat下这个项目当中，别把它放到eclipse下classpath，web项目是要部署到tomcat上去，如果不放到tomcat上当然找不到这个包。最好写代码把逻辑代码放到.java文件上，只要把结果放到web页面就好了，免得调试麻烦，再弄不好Hi我吧
