Okay so you know how to add some styles and CSS to your webpage, that’s a great start, but what about deciding where all your text should go? What if you wanted to setup your website so that you have some text on the left hand side, and some images along the right? This is where design and layout comes into play. The |

Cascading Style Sheets are a bit of a tricky beast in HTML. Given this fact, I wanted to dedicate an entire section to just this topic. Let’s start with the basics, shall we? What are Cascading Style Sheets (CSS)? Well, we’ve already talked a little bit about HTML formatting tags (like Cascading Style Sheets actually exist as a completely separate file to your HTML code. |

In this HTML tutorial I would like to introduce two concepts to you:
The DOCTYPECurrently as of the date this was published, web browsers are (mostly) supporting HTML 5. HTML has gone through several versions and variations over it’s lifetime, and because of this it’s highly suggested that you include something called a DOCTYPE. The purpose of a DOCTYPE is to tell the web browsers what version of HTML you are using on any given webpage. The benefit of telling the web-browser what version of HTML you are using is that you save it from having to “guess”, which can often lead to strange behavior. |

I’m so ridiculously excited to be introducing a whole new aspect of programming. Over the next few months I will be posting new articles on the topics of HTML, Javascript and jQuery. These are all technologies that you can use to create your very own interactive website. The really cool thing about building websites, is that you can leverage your existing knowledge of Java to create ever MORE powerful websites. But let’s not get ahead of ourselves, for now we’ll focus first on HTML, then we’ll move into Javascript/jQuery. But enough big picture talk, let’s get into our introduction to html shall we?
An Introduction to HTML…HTML stands for HyperText Markup Language, and all this really means is that HTML is not a programming language, but rather just a set of rules for structuring your text. This means that if you type out certain words in a particular way, you can create a website! Piece of cake right? For the most part, YES, it is a piece of cake |

The presentation layer is one of the three main layers in object-oriented programming. The three main layers include:
Now, these three layers are typically related to enterprise web applications. It’s a design pattern used to help separate your code out in three distinct areas that (if need be) can easily be switched out with another programming language or technology. So if you keep all of your presentation layer code in one area of your application, switching presentation layer technologies shouldn’t be too difficult. Same rules apply to the business and data layers. If you separated your code out properly, switching databases shouldn’t be too big of an issue. Having said that, we’ll be focusing on the presentation layer. The four big players (in terms of technology) in the presentation layer are as follows: |

In our last Hibernate lesson, you learned how to fix duplicate data from hibernate queries. In this lesson we’re going to focus on some of theaggregate functions that can be used with Hibernate, and of course that means diving into the What’s important to note is that Hibernate doesn’t ever refer to it as So, armed with this knowledge, let’s jump into the lesson! Grouping Data with HibernateIn our examples, I’m going to show you how to create a query with hibernate that will group your data in some manner. When we build our query, we will be focusing on using Hibernate’s First, let’s start off with an example that we will build on. |

How to Fix Duplicate Data from Hibernate QueriesThis problem was the bane of my existence when I first started using Hibernate because I had no idea where the problem was coming from. If you’re executing a query and finding that you have a bunch of duplicate records and haven’t a clue why, then you’re in the right place. You see the problem is typically caused by having left joins (or optional joins) in your objects. When you have a base object, like say Consider this scenario… A So what happens when you run a query that joins to the So because of this, Hibernate doesn’t massage the data for you, it just returns exactly what it got from the database. The ball is in your court to tell Hibernate what to do with records it has retrieved. There are two solutions to this problem:
