Demo for Slovak Scala User Group showing:

What it does and how

camel-scala-router is a standalone router that waits for incoming files in data/incoming. Once a file is dropped into data/incoming (e.g. data.txt) AND data.txt.ready files exists in the same location router processes the incoming file.

The expected format of the file is:

• 3 lines
• 1st line: match id (see slick.scala)
• 2nd line: time in format hh:mm:dd
• 3rd line: score

Once the file is processed it is saved into the DB, then a message is sent via JMS (ActiveMQ) to play application's actor that use play camel plugin

camel-scala-play is a play application that:

• can receive messages from scala router via JMS.
• it displays hockey match scores
• it can update the score of a match
• when score update is received scores are updates using WebScokets so users can see changes live
