In November 2016, I attended Devoxx conference in Casablanca. Around 1500 developers participated. A great event with many awesome speakers and sessions. Hot topics this year besides Java: Open Source Frameworks, Microservices (of course!), Internet of Things (including IoT Integration), Blockchain, Serverless Architectures.

I had three talks:

• How to Apply Machine Learning to Real Time Processing
• Comparison of Open Source IoT Integration Frameworks
• Tools in Action – Live Demo of Open Source Project Flogo

In addition, I was interviewed by the Voxxed team about Big Data, Machine Learning and Internet of Things. The video will be posted on Voxxed website in the next weeks.

In October 2016, the open source IoT integration framework Flogo was published as first developer preview. This blog post is intended to give a first overview about Flogo. You can either browse through the slide deck or watch the videos.

What is Project Flogo?

In short, Flogo is an ultra-lightweight integration framework powered by Go programming language. It is open source under the permissive BSD license and easily extendable for your own use cases. Flogo is used to develop IoT edge apps or cloud-native / serverless microservices. Therefore, it is complementary to other integration solutions and IoT cloud platforms.

Project Avatar was announced at JavaOne 2011. After no further information until JavaOne 2012, some new information was announced at this year’s conference. Even a little demo was shown in the keynote. Contrary to JavaFX, Avatar offers the realization of modern web applications without requiring a browser plugin. Web applications are realized with HTML5 and JavaScript (Nashorn implementation) on client-side, and Java EE backend on server-side. Avatar is also suitable for creating mobile applications (smartphone, tablet), because it does not depend on a browser plugin.

These days, we are starting a new project for realizing a Rich Internet Application (RIA). One of the first questions is: Which technologies and frameworks shall we use? The backend will be Java or another modern JVM language, as we are mainly experienced Java developer. In most use cases, we also prefer web frameworks, which allow to code mostly in Java, as many of us just have basic knowledge regarding HTML and JavaScript.

I used SmartGWT 2.3 in our last project (duration: 6 months). I wanna share my experiences with that component library in the following.

IMPORTANT: All information is my personal opinion! We bought the SmartGWT Power license, but we used SmartGWT without commercial training or commercial support. Regard this, when you read my stated CONs!

What is SmartGWT?

SmartGWT (http://code.google.com/p/smartgwt) is a component library for the Google Web Toolkit (GWT). Four different licences exists. The visual components are free (LGPL). Three further licences exists (see http://www.smartclient.com/product). These licences offer several additional features and components such as data binding, a “push”-implementation or Hibernate integration. We chose the Power Edition. SmartGWT is maintained by SmartClient (http://www.smartclient.com/smartgwt). SmartClient also offers commercial support.
