Tune up your JUnit test class template for Idea with the BDD-like syntax, Java 8 and the Mockito-AssertJ duo. Topics covered in this article may seem trivial. However, from my trainer experience I know that (unfortunately) it is not a common practice. Therefore, I decided to write this short blog post to propagate them and ...

@ControllerAdvice is a annotation provided by Spring allowing you to write global code that can be applied to a wide range of controllers, varying from all controllers to a chosen package or even a specific annotation. In this brief tutorial we will focus on handling exceptions using @ControllerAdvice and @ExceptionHandler (@InitBinder and...

In this example, we will discuss about Apache Ant Java Debug Example. Before we start with this article, it is expected to have knowledge of Java, Apache Ant, and software build and deployment process so that we understand the usage of Apache Ant. For more information about Apache Ant installation and configuration with a basic ...

JavaServer Pages, JavaServer Faces, and Expression Language In this article, I am going to take a look at JavaServer Pages (JSP) and Expression Language (EL) and then relate it to JavaServer Faces (JSF).  I will talk about how to access HTTP objects directly in the JSP and JSF code and you will see some examples ...

One of the most important development principles of the modern software design is the Dependency Injection (DI) which quite naturally flows out of another critically important principle called Modularity. This tutorial will explore a specific type of DI technique within the spring framework called Constructor-Based Dependency Injection which...

Imagine you have a stream that publishes events with unpredictable frequency. Sometimes you can expect dozens of messages per second, but occasionally no events can be seen for several seconds. This can be an issue if your stream is transmitted over web socket, SSE or any other network protocol. Silent period taking too long (stall) ...

Logging—maintaining a temporal trace of operations—is vital for any mission-critical system, no matter how big or small. Same was the case with our Project-X framework, which is why we wanted to get it right, right from the beginning. Contextual logging—where each log line automatically records its originating logical context,...

Gracefulness is not only an admirable human quality: it is also a must-have for any application program, especially when it is heaving the burden of mission-critical domains. UltraESB has had a good history of maintaining gracefulness throughout its runtime, including shutdown. The new UltraESB-X honoured the tradition and implemented graceful...
