When you build jars that are supposed to work with a specific JRE version, it's not sufficient to set the correct compiler level. Even if the compiler creates byte code for a particular language version, your code may accidentally use API that is not available in the class library of this Java version, and the compiler will not notice this. For example, if your source code...
Read MoreThe Eclipse Kepler release is just over 1 week away, and to help celebrate the release I'm counting down the Top 10 Kepler Features I'm most excited about. Number 5 on my list is the much improved integration between Maven and Eclipse. Integrating Maven based builds into Eclipse is not easy. This is because both Maven and Eclipse control the build process in fundamentally different ways....
Read MoreHot on the heels of the release of RAP 2.0 the bundles have been uploaded to Maven Central. Time for another coffee break with RAP and Maven. Before you get your coffee grab the updated sample project from GitHub[1]. $ cd /tmp $ git clone git://github.com/eclipsesource/rap-maven-examples.git and trigger the Maven action: $ cd rap-maven-examples/com.eclipsesource.rap.examples.maven $ mvn jetty:run While maven is doing it's job downloading the new RAP jars you can either go...
Read MoreLately I was talking with a colleague if it is possible to kickstart a RAP standalone "Hello World" example in less than a coffee break(*). Well it depends… on the content of your local Maven directory and/or your internet connection. ;-) To make this happen you should postpone getting your coffee for now. Just go to a local temporary folder and grab the sample project from GitHub[1] $ cd...
Read MoreWe are currently working on a very interesting project together with basis06 which has Apache Karaf as a target runtime. Coming from the Eclipse space this is really a challenge for the following reason: when you develop OSGi applications within Eclipse you are used to the PDE Tooling (Plug-In Development Environment) together with its concepts like features. You are also used to Equinox with its...
Read MoreEditor's note: The Restfuse project is no longer maintained and has been archived. However, you can still access the sources on GitHub. As you might know from previous posts, most of my work time has something to do with the development of REST based systems. The systems we develop are mostly written in Java. To ensure that a system works, we have a step in our...
Read MoreHave you ever heard about RWT standalone? RWT standalone applications use the widget toolkit of RAP called RWT for their user interface. These applications can be standard Java applications with no need to create an OSGi based application. For Java applications it can be quite challenging to find the required dependencies but Maven can help here. And, to make the life...
Read MoreIn the past I have said some unkind words about about maven's pom.xml format. My aversion to xml heavy configuration has drawn me to more lightweight approaches to build systems, like gradle for example. At the same time, I was intrigued: if a tool like maven is seeing such a widespread use despite its cumbersome format, there must something to make up for it. My...
