Nothing makes you want Groovy more than XML
I’m in Delaware this week teaching a course in Java Web Services using RAD7. The materials include a chapter on basic XML parsing using Java. An exercise at the end of the chapter presented the students with a trivial XML file, similar to: <library> <book isbn=”1932394842″> <title>Groovy in Action</title> <author>Dierk Koenig</author> </book> <book isbn=”1590597583″> <title>Definitive…

Library quirk in the new Eclipse, and random framework musings
I’ve been working with Struts 2 recently, and like most frameworks it relies on a set of jar files. I like to work with Eclipse as my primary IDE. In that framework, my normal mode of operating is to create a User Library containing the jar files I need and then add it to my…

Go to see Grails, learn about Hibernate
Today I finally got to see the two Grails presentations by Jason Rudolph at No Fluff, Just Stuff. It’s not really an exaggeration to say I decided to attend the conference largely because I knew he’d be there. I like the NFJS conferences, but since I’m a one-person company, the “budget” for the conference comes…

Some No Fluff, Just Stuff observations
I’ve finished two of the three days of the current No Fluff, Just Stuff conference, officially known as the New England Software Symposium. I’ve got a fair amount to process now, but here are some random observations, in no particular order: If the NFJS people have any say in it, Groovy and Grails are definitely…

Where have I been (my Google Maps Mashup)?
The user interface leaves a lot to be desired, but my Google Maps mashup went live today. If you want to see where I’ve taught courses over the past three years, you can go here and see. All of the data is stored in a very simple database consisting of three tables: Courses, Locations, and…

MyEclipse + JPA + Spring + Hibernate = DAO (mostly)
I just about have my Google Maps mashup working. When it’s deployed, it’ll show markers for each location where I’ve taught a course. Eventually I’ll filter them by year, connect them to home with polylines, and maybe more. As a mashup, it’s not the most interesting application ever written, but it’s given me a good…

WebSphere Portal isn’t as horrible as I thought…
I remember several years back I was flipping through the pay cable channels and lucked into a stand-up show by Paul Rodriguez at San Quentin prison. Through the magic of Google, here’s a link to the DVD. The concert was in 1995, apparently, so I guess it really was a while ago. As I recall,…

The Spring Framework outranks private
I’ve been using the Spring framework for about a year now (or maybe more — it’s amazing how fast time goes by these days). I’ve also been teaching courses in it using Capstone Courseware materials. As is normal with Capstone materials, they tend to skip quickly through the “Hello, World!” version of whatever technology they’re…

When is EJB not Java EE?
The answer is, when it’s and EJB3 plug-in inside JBoss 4. I’ve been playing with the EJB3 spec a lot recently, especially working with the Java Persistence API (JPA) portion for entities. I’ve said it before here, but I’ll say it again — I really like the way it’s put together. (With one exception, of…

Persistence providers are not all alike
At the NFJS conference I attended over the weekend, I wound up going to two session by Mark Richards. His topic was the JPA specification as part of the overall EJB3 spec. As I’ve mentioned here, I’m quite interested in that. Will and I just finished an introductory EJB3 course for Capstone where I wrote…
