Solr Cell NoSuchMethodError_问答_开发者_运维开发者技术经验分享

I am trying to get Solr up and running with Solr Cell.

In order to do that I installed Solr using apt-get install solr. I have now managed to set it all up but when updating documents with a PDF document, the following error is produced (by running curl "http://127.0.0.1:8080/solr/update/extract?literal.id=1&commit=true" -F "myfile=@/home/vagrant/test.pdf"):

I installed Solr Cell using the following commands:

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

Can anyone tell me what is wrong?

It seems you didn't update the Solr war. SolrResourceLoader.getClassLoader() is a relatively recent addition.
