    Now that JavaEE 7 is out of the starting blocks and running free I thought I’d have a first look. I decided that as I’ve not had a look at the JavaEE tutorial for a while I’d work my way through it as both a refresher and to find out about the new API’s available.…

    The humble label is probably one of the most used widgets in the UI designers toolkit so getting to know it inside and out is important. A common task it is to update a label to display some new information depending on the state of the application. Depending on where that new information comes from…

    After a bit of a break away doing other things I’m back on a project that uses JavaFX 2. So far this project hasn’t required much in the way of persistence either for settings or data but a new feature I’m working on makes use of a database. I use JPA 2 for web based…

    So you’ve just finished parsing a document with your validating namespace aware document factory and you’ve gone to select some nodes using XPath and nothing has appeared (no nodes where selected).

    By default every single class that you create with NetBeans will start with a header that tells you how to change the template. This header has found it’s way into just about every file in all my projects and it serves no useful purpose, why it can’t just be an empty comment I don’t know…

    Just when I think that I’ve got everything working I hit another issue. This time it’s with Subversion. I’m trying to create a new job so I select Subversion under the SCM section and enter the appropriate URL. Hudson tells me that I need to enter credentials so I click the link which takes me…
