TomEE ApplicationComposer is a nice solution for embedded EE testing. The goal is to describe its application in Java and deploy this model. However it starts OpenEJB and deploys/undeploys the application either by class or method depending the setup.
When this feature can be insane for small deployments which would benefit of an insanely easy configuration and simple mock solution it can be an issue for application deploying again and again the same model.
To avoid that the coming TomEE 7.0.0-M2 provides a new JUnit runner but you can already benefit from it with a single class!
More and more applications are composed of REST services. In JavaEE land it means you develop and expose JAX-RS services.
Once developped and well tested with TomEE the first thing you will realize is that to make an API useful you need to document it. There are a lot of ways to do it but Swagger seems to be the trendy one and it is indeed a nice solution as we’ll see in this post.
This powerful architecture can sometimes reveal some challenges in the build pipeline.
However today it is not that hard to mix both frontend and backend build tools to get a single build pipeline easily integrable in a continuous integration solution.
To illustrate that we’ll digg into how to create an Angular 2 application packaged with Maven.
Let’s see why and how to use this feature…
When you develop an application relying on a container for its awesome features you often hit the fact you use several code bases to do the same thing. In the context of this post it will be the ciphering of the passwords in the configuration:
- TomEE does it using
- DeltaSpike does it using
So finally you end up having to maintain two ciphering solutions which makes hard to production teams to maintain the configuration without developpers.
By default Apache Johnzon JSON-Java mapper uses the pattern “yyyyMMddHHmmssZ” for Dates. The good thing about this pattern is that it is fast enough for most cases. However, its drawback is not as common as the ISO8601 format of the RFC822.
The solution is quite simple.
Even if it comes from test side of OpenEJB, ApplicationComposer is now a solution to develop microservices. Because of this evolution it now gets a maven plugin to be able to go further in the development pipeline.
