When I use Tomcat 7.0.73 and Solr 6.4.1 to code something on a servlet, ERRORs like this occured,

"java.lang.UnsupportedClassVersionError: org/apache/solr/client/solrj/SolrServerException : Unsupported major.minor version 52.0 (unable to load class org.apache.solr.client.solrj.SolrServerException)",

I do believe this has nothing to do with code, but a specific Class named SolrServerException. Anyone can tell me how to fix this? Thanks.

It usually means that the java code was compiled to a later version of java than the jvm that is trying to run it. – Steve Smith Feb 17 '17 at 09:36
