connect bonita to a mysql DB

i created a simple process to test mysql connector , i configurated the connector hostname:port/database , the user and the password , i created the query but an error was shown :
"java.lang.reflect.InvocationTargetException
org.bonitasoft.engine.bpm.connector.ConnectorExecutionException: USERNAME=install | org.bonitasoft.engine.core.connector.exception.SConnectorException: org.bonitasoft.engine.connector.exception.SConnectorException: java.util.concurrent.ExecutionException: org.bonitasoft.engine.connector.exception.SConnectorException: org.bonitasoft.engine.connector.ConnectorException: 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."

thanx.

You also need to add the JAR file to the tomcat\lib folder.

PS: As this reply answers your question, please mark as resolved by ticking the tick mark on the left of this reply.

The .jar file already exists
mysql-connector-java-5.1.23-bin.jar(Active) .
what is the problem so ??

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

Please don’t add another answer, just add a comment…

Can you share the process so I can have a look?

regards

No need for chart because I am still in the test phase of connector, so just test the connector with a simple request . but no result :confused:
