Solr错误实例化请求处理程序

好吧，我放弃了。我找不到解决方案。全文：我使用在Jetty上运行的ManifoldCF v.5.1连接到Opentext（一切正常，我可以抓取Opentext），现在我已经在Tomcat 7上运行Solr 4.0 Alpha，并从ManifoldCF获取输出。但是，只要ManifoldCF试图将数据交给Solr。我得到这个错误：Solr错误实例化请求处理程序

我已经在solarconfig.xml中尝试了几个请求处理程序，它们都以相同的方式失败。我读过apache-solr-cell * .jar必须在solr.war中，但似乎无法证实或使用ant将其合并。请指教......

答案是Solr不工作，因为Tomcat 7.0.3中存在一个错误。您需要使用tomcat6或tomcat7 v7.0.5或更高版本。点击tomcat7下的存档链接查看大于7.0.3的版本。 – djm 2012-10-05 16:20:14

好吧我修复了它。通过将所有的manifoldcf jar复制到webapps/solr/lib文件夹中，我在tomcat 7.0.8中运行了solr 4.0。 – djm 2012-11-21 21:19:11

你能解释一下你做了些什么吗？每次我想将文档插入solr时，我都有ExtractingRequestHanlder错误。 – FrenkyB 2013-12-16 06:01:45

也许您需要删除此请求处理函数的startup="lazy"属性？
