We have seen how to develop a ZK based application and deploy it to OpenShift. Google has also a Paas offering called Google App Engine(GAE) which supports Java, Python and Dart applications. Gaelyk is a simple Groovy based toolkit to develop and deploy application to GAE. In this article lets build a simple Gaelyk based [...]

In our post on developing sample Todo Application using JavaFX and MongoDB, we showed how we can use MongoDB, JavaFX to create a sample application. In that post we used the API provided by MongoDB to carry out the DB operations. In this post lets look at how we can use Morphia to carry out [...]

We at JavaBeat have thought of coming up with a fortnightly post, a JavaBeat Newsletter covering the latest news in the Java ecosystem be it in the Java language, Other JVM based languages, Cloud support, Tools and other frameworks and also few noteworthy posts added on JavaBeat.
