localhost：8080/solr/browse給出了延遲加載錯誤

Question

我是Solr的新手，剛剛在CentOS上安裝了Tomcat6和Solr 3.6.1。我設法從我的MySQL表中添加一些數據，並使用exampledoc的xml和http://localhost:8080/solr/update來用樣本數據填充索引。我使用的solrconfig.xml一個編輯的版本從examplesdoc

問題：當我去瀏覽界面在http://localhost:8080/solr/browse，我得到了以下日誌文​​件中的錯誤。我不明白爲什麼會出現錯誤，我有什麼想法可以解決這個問題？

錯誤：

這看起來像失蹤圖書館給我。

檢出http://wiki.apache.org/solr/VelocityResponseWriter#Using_the_VelocityResponseWriter_in_Solr_Core看看你有沒有在正確的地方所有的圖書館。
