"Out of the box Jersey generates basic WADL at runtime that you can obtain from your REST app via GET http://path.to.your/restapp/application.wadl. Additionally you can configure Jersey to create an extended WADL including e.g. additional doc elements or javadoc read from your resource classes: There's a custom doclet that writes your javadoc to a file so that it can be used to extend the WADL. Additionally there's the maven-wadl-plugin that allows you to create the WADL without your running REST app."

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."

Jettison is a collection of Java APIs (like STaX and DOM) which read and write JSON. This allows nearly transparent enablement of JSON based web services in services frameworks like CXF or XML serialization frameworks like XStream. There are currently two included conventions for mapping JSON to XML. The first, is BadgerFish which implements the full XML infoset in JSON using various techniques. The second, is called the "mapped" convention. It allows you to manually map XML namespaces to JSON element prefixes. Jettison was developed for usage in XFire and CXF to enable JSON based services. Later it also found its place in Java object serialization with XStream To learn more, see the User's Guide.

The Virgo Web Server from EclipseRT is a completely module-based Java application server that is designed to run enterprise Java applications and Spring-powered applications with a high degree of flexibility and reliability. It offers a simple yet comprehensive platform to develop, deploy, and service enterprise Java applications. The Virgo kernel supports the core concepts of Virgo and is not biased towards the web server, thus enabling other types of server to be created. The kernel can also be used stand-alone as a rich OSGi application platform. A server runtime can easily be constructed by deploying suitable bundles on top of the kernel.

Java Topic / Java tutorial An exception is an abnormal condition that arises in a code sequence at run time. An exception is a run-time error. Most of these run-time errors could be prevented by doing proper input validation as shown in 151, but in cases where we can not prevent effectively we can use the exception handling mechanism provided by Java.

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