Creating a connection pool should be a simple and straight forward task in an application server but sometimes it just becomes unnecessarily difficult. That is completely true for creating MySQL connections pools in all versions of GlassFish from 3 onwards.
One of the applications I maintain currently only runs against Microsoft SQL Server. For the most part this hasn’t proven to be that much of a problem as everyone who uses the application also runs MS SQL. The problem comes when I want to deploy and test it on one of the company servers because …
For a while now I’ve been meaning to get Hudson installed and running but what with one thing and another I’ve always put it off (I put it down to being a lone developer). What with everything else going on things like Hudson get pushed to the back of the queue all the time even …
Beginning with Expression Language (EL) 2.2 it is possible to call method with arguments. I feel that most of the time it is generally a good idea to try not to use this feature because it breaks the KISS principal but when you need it it can be a life saver.
A project I’m working on recently presented me with the problem of totally dynamically creating a data table on a JSF page. At first sight I assumed this would be fairly trivial since I had created a number of other components dynamically with no problems. The difference though was that the other components (for example …

One of the projects I’m currently working on requires me to build a component tree dynamically. To complicate matters the components also require ajax functionality – in this case they are panels that need to be closed and notify a listener.
After putting together the first page on writing a dynamic dashboard with PrimeFaces I descovered that the method I had come up with wasn’t as good as it could have been. Most noteably it didn’t work properly when the dashboard was updated via a partial page refresh. Typically that type of update would result in a …
I do a fair bit of work with the PrimeFaces JSF library and it is, IMHO, the best set of JSF widgets currently available. PrimeFaces has an excellent demonstration site as well which gives examples of the most common usage patterns of each widget available. Occasionally though it’s necessary to stray outside what is demonstrated …
