Question

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，并使用带有http://localhost:8080/solr/update的exampledoc＆＃xml来用索引填充样本数据。我使用solrconfig.xml

中经过编辑的examplesdoc版本

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

错误：

这对我来说就像是缺少图书馆。

查看http://wiki.apache.org/solr/VelocityResponseWriter#Using_the_VelocityResponseWriter_in_Solr_Core，看看您的所有图书馆都在正确的位置。
