Hi Peter, I've also faced the same problem which you did. I also changed my data-config.xml file same as yours and checked that my MS Sql Server is running on default port i.e, 3306 given the same to connection string but still its not working.
Could you pls. share your solrconfig.xml and schema.xml file so that I can change it accordingly and my problem would be solved Thanks ALOK -- View this message in context: http://lucene.472066.n3.nabble.com/Indexing-data-on-MSSQL-failed-Caused-by-org-apache-solr-common-SolrException-Error-loading-class-com-tp1015137p1444820.html Sent from the Solr - User mailing list archive at Nabble.com.
