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?

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. |
