我是 Solr 的新手，刚刚在 CentOS 上安装了 Tomcat6 和 Solr 3.6.1。我设法从我的 MySQL 表中添加了一些数据，并使用 exampledoc 的 xmlhttp://localhost:8080/solr/update来用示例数据填充索引。我正在使用的编辑solrconfig.xml版本examplesdoc

问题：当我转到 的浏览界面时http://localhost:8080/solr/browse，我在日志文件中收到以下错误。我不明白为什么会发生错误，有什么想法可以解决这个问题吗？

错误：

对我来说，这看起来像是缺少图书馆。

查看http://wiki.apache.org/solr/VelocityResponseWriter#Using_the_VelocityResponseWriter_in_Solr_Core看看你有没有在正确的地方所有的图书馆。
