Building Java 8 Web Applications with Microservices

Building Java 8 Web Applications with Microservices LiveLessons Workshop utilizes live code demonstration to build a fully functional application using minimal external dependencies and Java 8. This application consumes a real-time feed of high-velocity data, contains services that make sense of the data, and presents it in a JavaFX dashboard. Along the way, you’ll encounter Java 8 streams, lambdas, new ways of working with collections, and the new date and time API.

Java and MongoDB Rapid App Prototyping: Application Development using HTML5, AngularJS, Groovy, Java, and MongoDB

In this Developer Talk, Java engineer Trisha Gee demonstrates with live coding how to build a web application in one hour. On the front-end, she uses AngularJS, HTML5, JavaScript, and Bootstrap. On the back-end, Dropwizard, MongoDB, Morphia, Gradle, and Groovy are utilized, and Spock is used for testing.
