Hi Sanjay,

Thanks for posting on PSC.

As per logs shared, "PoolableConnectionFactory" SQLException is occurring and this happens only when you have a network issue, please verify your database communication link. Make sure that your application has network access to your database environment(It may be restricted by any firewall and blocking connection ports ).

Also, I have found similar stack trace reported earlier and probable root cause:-

Maybe there is no service listening on the port you are trying to connect to. Following things could be happening

- The server is not started.

- You are trying to connect to the wrong port number.

Please try using a different port in server.xml and restarting your Tomcat.

Hope it addresses issue on your end. Kindly notify if it does by marking this post as answered.

Regards,

Asif
