Running the client via IntelliJ

I am new to Corda and following this link. I am running from IntelliJ by selecting "Run Example RPC Client" from run configuration and click on green arrow. And I am getting the error on logs as below :

Exception in thread "main" ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119007: Cannot connect to server(s). Tried with all available servers.]

How to resolve this exception ?
