The Way of the Pro

software-development-2-logo

Enterprise developers are serious professionals. They don’t waste their time for creating silly things. They leave this to the hipster developers. Enterprise developers write software which keeps our society running. They are the backbone of the modern society, and they know it. Enterprise developers claim that they aren’t driven by money. They are driven by “professionalism” and the will to ...

Java EE: The Basics

java-interview-questions-answers

Wanted to go through some of the basic tenets, the technical terminology related to Java EE. For many people, Java EE/J2EE still mean Servlets, JSPs or maybe Struts at best. No offence or pun intended! This is not a Java EE ‘bible’ by any means. I am not capable enough of writing such a thing! So let us line up the ...

What are Mockito Extra Interfaces?

mockito-logo

Mockito is my favored little helper if it comes down to write light weight JUnit tests. It is very useful to replace the ‘real’ dependencies of a unit under test easily by mocks if necessary. In particular when working on the borderline to framework APIs such dependencies can otherwise be very expensive to setup. But sometimes the situation is a ...

JUnit ExpectedException rule: beyond basics

java-logo

There are different ways of handling exceptions in JUnit tests. As I wrote in one of my previous posts, my preferable way is using org.junit.rules.ExpectedException rule. Basically, rules are used as an alternative (or an addition) to methods annotated with org.junit.Before, org.junit.After, org.junit.BeforeClass, or org.junit.AfterClass, but they are more powerful, and more easily shared between projects and classes. In this ...

How to use NodeManager to control WebLogic Servers

oracle-weblogic-logo

In my previous post, you have seen how we can start a WebLogic admin and multiple managed servers. One downside with that instruction is that those processes will start in foreground and the STDOUT are printed on terminal. If you intended to run these severs as background services, you might want to try the WebLogic node manager wlscontrol.sh tool. I ...

Application Security – Can you Rely on the Honeymoon Effect?

software-development-2-logo

I learned about some interesting research from Dave Mortman at this year’s RSA conference in San Francisco which supports the Devops and Agile arguments that continuous, incremental, iterative changes can be made safely: a study by by the MIT Lincoln lab (Milk or Wine: Does Software Security Improve with Age?) and The Honeymoon Effect, by Sandy Clark at the University ...

Java can finally join strings

java-logo

I am sure you were in a situation in which you wanted to join multiple strings. If you were using a programming language other than Java you probably used the join() function provided by the programming language. If you were using Java you could not do this. There was no join() method. The Java Standard Class Library provided you tools ...
