Hello Joseph,

Can you describe your configuration? It is hard to help you from this error message alone.

Also, did you search the forum already? There is a [post about this error message already](https://discuss.elastic.co/t/logstash-filter-jdbc-streaming-jdbc-could-not-load-jdbc-mssql-adapter-adapter-class-not-registered-in-adapter-map/275546/5).

Also, there is a github issue [here](https://github.com/logstash-plugins/logstash-integration-jdbc/issues/73) that might help you.

Best regards  
Wolfram
