Re: Dataimport: Could not load driver: com.mysql.jdbc.Driver
Try referencing the jar directly (by absolute path) with a statement in the solrconfig.xml (and reloading the core). The DIH example shipped with Solr shows how it works. This will help to see if the problem with not finding the jar or something else. Regards, Alex. On Wed, 9 Oct 2019 at 09:14, Erick Erickson wrote: > > Try starting Solr with the “-v” option.

Re: Dataimport: Could not load driver: com.mysql.jdbc.Driver
Try starting Solr with the “-v” option. That will echo all the jars that are loaded and the paths. Where _exactly_ is the jar file? You say “in the lib folder of my core”, but that leaves a lot of room for interpretation. Are you running stand-alone or SolrCloud? Exactly how do you start Solr?

Re: Dataimport: Could not load driver: com.mysql.jdbc.Driver
Thanks Koji. I just tried to change the permission of the driver file to 777, still can not found the driver. I put the driver into the folder with the original driver is and deleted the original one. I don't know why solr can find the original one (if I don't change anything), but not this one.

Re: Dataimport: Could not load driver: com.mysql.jdbc.Driver
Hi Koji
I finally found the reason for this problem:
I download the tar file of the driver and unzip it in windows. Then I put
the jar file into the server. I don' t know why, but it doesn't work. It
works when I put the tar file and unzip it in the server.
Thanks a lot for your time!!!
