Session replication demo

Once the application is deployed, perform the following steps:

1. Open the application link from node13 http://localhost:8380/beosbank-web/.
2. Fill the money transfer details and click on Next to select the payment options:
   • Sender Country: France
   • Receiver Country: Cameroon
   • Amount to send: 100
   • Sender: Noe Nono
   • Receiver: Michele Bertille

1. Click on the Next button to reach the Payment Infos tab:

• Fill the credit card number field with the value: 000-1111-2222 3333
• Click on the Next button.
• Try to open the application URL from the second node of the group (host2:node23) in another tab of your browser--http://localhost:8780/beosbank-web/:

You will automatically arrive on the first tab with data entered from the node13 session:

• Sender Country: France
• Receiver Country: Cameroon
• Amount to send: 100
• Sender: Noe Nono
• Receiver: Michele Bertille

The session you started on node13 session has been replicated on node23; if you shut down one node, the caller can still find this data from the other node:

[domain@127.0.0.1:9999 /] /host=host1/server=node13:stop
{"outcome" => "success",
"result" => "STOPPING"
}

http://localhost:8780/beosbank-web/ => OK

With this configuration, in order avoid request failures, the caller has to implement a failover process to automatically switch to a running node when the current node goes down. This approach makes the client code become strongly coupled to the server instance URLs.
