It looks like you have older jar files in your classpath, evidenced by the line: Caused by: java.lang.ClassCastException: class org.apache.solr.handler.dataimport.DataImportHandler
bq: Originally, there is not the lib folder under solr, so I created it for adding several jar files. This is really suspicious. Lots of Solr wouldn't work if there were no lib directory, so I suspect you have jar files in two or more places and that they're different versions, but that's just a guess.
