尝试在Solr中索引PDF时发生ClassCastException ExtractingRequestHandler
[英]ClassCastException ExtractingRequestHandler while trying to index PDF in Solr
问题描述
I'm facing some difficulty indexing PDF in Solr. 
我在Solr中索引PDF时遇到了一些困难。 Initially I had a lot of JAR missing, which I included all (specially from "dist" and "contrib\\extraction" folder. But now when I try to index my PDF I'm facing this ClassCastException ExtractingRequestHandler. Have anyone encountered this before or have any idea what's going wrong? 最初，我缺少很多JAR文件，其中包括所有文件（特别是“ dist”和“ contrib \\ extraction”文件夹中的文件。）现在，当我尝试为PDF编制索引时，我遇到了这个ClassCastException ExtractingRequestHandler。知道发生了什么事吗？

Try putting solr-cell.jar in your classpath. 尝试将solr-cell.jar放入类路径中。 ExtractingRequestHandler class is inside solr-cell jar file. ExtractingRequestHandler类位于solr-cell jar文件中。
Put it under /webapp/lib folder followed by restart. 将其放在/ webapp / lib文件夹下，然后重新启动。
