shivani133199699 Posted December 20, 2016 Share Posted December 20, 2016 hello,I tried making a new data adapter. I installed the mysql driver, included the jar file into the classpath and included the jar file location for the driver class path. I then clicked on test but got the following error.com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. Link to comment Share on other sites More sharing options...
