5 Ways to Contribute to GlassFish without being a Programming Genius. Andy Lester posted the original guide about 14 Ways to Contribute to Open Source without Being a Programming Genius or a Rock Star back in March and I really liked the idea. And this is why I decided to adopt this post a bit and tell you how and what you could do to support your favorite Appserver and technology. Ask not what GlassFish can do for you, but ask what you can do for GlassFish! (freely adapted from John F. Kennedy) First of all: Don't be afraid! We’re just people who get stuff done.

Contents About WebSPHINX WebSPHINX ( Website-Specific Processors for HTML INformation eXtraction) is a Java class library and interactive development environment for web crawlers. A web crawler (also called a robot or spider) is a program that browses and processes Web pages automatically. WebSPHINX consists of two parts: the Crawler Workbench and the WebSPHINX class library. Crawler Workbench The Crawler Workbench is a graphical user interface that lets you configure and control a customizable web crawler. Visualize a collection of web pages as a graph Save pages to your local disk for offline browsing Concatenate pages together for viewing or printing them as a single document Extract all text matching a certain pattern from a collection of pages.
WebSPHINX class library The WebSPHINX class library provides support for writing web crawlers in Java. Download First, you need Java 1.2 or later installed on your computer.

Let's assume that you are a Java developer who just started working on a large Java application which comprises of 2000 classes and uses multiple frameworks. How would you go about understanding the code base? In a typical enterprise Java team, most of the senior developers who can help you are likely to be quite busy. Documentation will be sparse. You will need to quickly deliver and prove yourself to the team. How would you resolve such a situation? This article offers some suggestions to Java developers starting on a new project. 1. Let me ask you this - why do you want to understand the code in the first place? Even Senior Java developers with more than 10 years of solid coding experience may not understand the working of certain parts of the application despite being on the same project for more than a year (assuming they are not the original developers).
Then how do they manage? 2. So am I discouraging you from understanding the application architecture? 3. 4. 5. 6. VineetReynolds / Java EE 6-Galleria. Bitbucket is a code hosting site with unlimited public and private repositories. We're also free for small teams! Sign up for freeClose The Java EE 6-Galleria is a demo application demonstrating the use of JSF 2.0 and JPA 2.0 in a Java EE project using Domain Driven Design. It was written to serve as a showpiece for domain driven design in Java EE 6. The domain model of the application is not anemic, and is constituted of JPA entities. The entities are then used in session EJBs that act as the application layer. The Java EE 6 Example - Galleria - Part 1. Have you ever been wondering where to find some good end-to-end examples build with Java EE 6?
I have. Most of the stuff you find on the net is very basic and doesn't solve the real world problems. This is true for the Java EE 6 tutorial. All the other stuff, like most of what Adam Bien publishes are a very tight scoped examples which also doesn't point you to a more complete solution. About the Galleria The high level description of the project is the following: The Java EE 6-Galleria is a demo application demonstrating the use of JSF 2.0 and JPA 2.0 in a Java EE project using Domain Driven Design. Domain driven design using Java EE 6 DDD as an architectural approach, is feasible in Java EE 6. Domain Layer The application contains four domain entities for now - User, Group, Album and Photo which are the same as the JPA entities in the logical data model. Application layer The application layer exposes services to be consumed by the presentation layer. 5 More Notable Java 7 Changes. Continuing the exploration of Java language features in JDK7 which I began in my previous installment on Project Coin, I will discuss the following Java 7 enhancements: Improved type interface for generic instance creationSimplified varargs method invocation NIO.2 improvementsRich GUI deploymentSockets Direct Protocol This list is by no means complete; it serves only as a compilation of the features I find most notable.
Improved Type Interface for Generic Instance Creation This is a tiny change when compared with other, exhaustive Java 7 language changes. Having said that, improved type interface for generic instance creation makes a big difference in the way Java code will be written. For example, consider the following declaration for a regionMap data structure, which dictates that the structure hold a key value pair with key as Integer and value as a List of String type. Map<Integer, List<String>> regionMap = new HashMap<Integer, List<String>>(); Simplified Varargs Method Invocation.
