Question

好的，我放弃了。我无法找到解决方案。全文：我正在使用在Jetty上运行的ManifoldCF v.5.1连接到Opentext（一切正常，我可以抓取Opentext），现在我在连接的tomcat 7上运行Solr 4.0 Alpha来获取ManifoldCF的输出。但是，只要ManifoldCF尝试将数据移交给Solr。我收到这个错误：

我在solarconfig.xml中尝试了几个请求处理程序，它们都以同样的方式失败。我读到apache-solr-cell * .jar必须在solr.war中，但我似乎无法确认或使用ant合并它。请指教......

也许您需要删除此请求处理程序的startup="lazy"属性？
