问题描述

| 我正在尝试启动Solr并与Solr Cell一起运行。 为此，我使用ѭ0installed安装了Solr。 我现在设法全部设置好了，但是在用PDF文档更新文档时，会产生以下错误（通过运行
curl \"http://127.0.0.1:8080/solr/update/extract?literal.id=1&commit=true\" -F \"myfile=@/home/vagrant/test.pdf\"
）：

我使用以下命令安装了Solr Cell： 
mkdir -p /usr/share/solr/lib
cd ~
wget http://apache-mirror.dkuug.dk//lucene/solr/3.2.0/apache-solr-3.2.0.tgz
tar -xvf apache-solr-3.2.0.tgz
cd apache-solr-3.2.0/
cp dist/apache-solr-cell-3.2.0.jar /usr/share/solr/lib/
cp contrib/extraction/lib/*.jar /usr/share/solr/lib/
/etc/init.d/tomcat6 restart
谁能告诉我哪里错了？     

解决方法

        看来您没有更新Solr
war
。 
SolrResourceLoader.getClassLoader()
是一个相对较新的名词。
