There are several options to handle the Java properties files:
To read java properties files from the classpath:
The properties files can be stored in the classpath. This way they can be put inside jar files and it’s really useful for web applications when the absolute location of the properties files is not known. When I tested [...]

I just took the Google Collections Library and start playing with it. I discovered a class I needed in many and many situations in the past. I’m talking about Multimap. Actually Multimap is an interface having a few classes implementing it. Along with some other interfaces it comes to fulfill a gap in the Java Collections.

Ant is a build tool written in Java, intended to be used for Java build processes. Ant is used for building small and large projects as well. You can use ant not only for automation of building Java projects, but for automating any complicated and repetitive tasks. Ant is using xml files to define tasks [...]

There is a pretty common situation to use a java classes generator and to create classes based on a defined pattern. Hibernate, Castor, Jaxb are a few examples. I prefer to have those classes packed in a separate jar file. Since they are generated files it’s not a good practice to modify them, so there [...]

Java or .NET languages does not allow multiple inheritance and usually we don’t need multiple inheritance in our projects. However there are cases when inheriting from multiple classes is a necessity. There are a few tricks we can apply in order to be able to get what multiple inheritance gives us in the languages where [...]

A marker interface is a design pattern consisting in an interface with no methods declared. All the classes implementing this interface don’t have to implement a method for the interface(since it doesn’t have an interface), but we can say that the classes implementing the interfaces are marked. For example in Java we have the Serializable [...]

Lets take this time in consideration a real life project. Most of the time Ant is used to compile and build java projects. This means generating, compiling and building jar files. For this we are going to define severals tasks. Lets consider the we create a buid.xml file in the directory where sources are located. [...]

This is the ant task I’m using to generate POJO and mapping files from a DB Schema (mysql).

I was looking recently for some java framework to save some objects in xml files. Until now I’ve tested from a noob perspective 2 frameworks: JAXB and Castor. Don’t get misleaded by my judgment because I didn’t use any of them very deep.
I was playing with JAXB some time ago and at that time [...]
