"http://www.atompub.org/ defines a simple interface over HTTP to publish and subscribe to artifacts (files) and collections of artifacts (services/packages). AtomPub interface serves following purposes: 1: provide "feeds" for people/systems to monitor for changes: For example, user subscribes to a feed which lists contents of package or user subscribes to feed which lists changed contents in a package 2. provide the default remote api to push/pull content and meta data from the repository. This allows other applications to integrate with Guvnor by accessing repository content via atom pub programmatically."

When creating a REST api with Java EE 6 and JAX-RS there comes the time when you start thinking about security. In our case we were trying to set up HTTP Basic Auth for the REST api to identify users and keep them from deleting other peoples stuff. It took me a while to understand the different aspects of configuring HTTP Basic Auth when using GlassFish:

"This Tech Tip presents some of the features of inheritance supported in the Java Persistence API. A sample package accompanies the Tech Tip. It demonstrates some of the features discussed in the tip. The examples in the tip are taken from the source code for the sample (which is included in the package). The sample uses an open source reference implementation of Java EE 5 called GlassFish. You can download GlassFish from the GlassFish Community Downloads page."

YAML is a data serialization format designed for human readability and interaction with scripting languages. SnakeYAML is a YAML parser and emitter for the Java programming language. SnakeYAML features a complete YAML 1.1 parser. In particular, SnakeYAML can parse all examples from the specification. Unicode support including UTF-8/UTF-16 input/output. high-level API for serializing and deserializing native Java objects. support for all types from the YAML types repository. relatively sensible error messages.

This video explains about the increment, decrement, modulus and compound assignment operators under the Arithmetic Operators Group. It discusses few examples using these operators.

Know more about basic java functions with unique examples. Java is a best technology for security and easy to use.Here we clear you basic java concepts with best tutorials.

Do you Want To know About method Overloading in Java? We provide you best notes on method overloading with great examples which can easily understandable for everyone.There are two ways to overload the method.

If a class have multiple methods by same name but different parameters, it is known as Method Overloading. If we have to perform only one operation, having same name of the methods increases the readability of the program.

Quick guide on what is Constructor overloading and how to implement constructor overloading in Java.

Encapsulation is a process of wrapping code and data together into a single unit. It is a way to achieve data hiding.

Runtime Polymorphism. Let's learn what is runtime polymorphism with suitable example.

In this page, we will learn how to write the hello java program. Creating hello java example is too easy. Here, we have created a class named Simple that contains only main method and prints a message hello java. It is the simple program of java.

Writing your own logging framework is the perfect coding crime. If you can convince your manager to put it on the project plan, you are guaranteed to have success. At the end of each day, you will go home feeling happy and satisfied. It will feel like you are doing something creative. You will get the intellectual stimulation without the risk of failure. Even the Sun engineers fell into this trap. Prior to Java 4, we had a perfectly good logging framework in Log4J. However, instead of adopting this into the standard Java distribution, we ended up with java.util.logging. There are lots of Java logging frameworks available, even meta-logging frameworks like SLF4J and Jakarta Commons. These are supposed to abstract the logging frameworks so you can change the implementation without touching your code. http://www.javaspecialists.eu/archive/Issue177.html
