Welcome Welcome to our blog about all kind of topics that are related to software development. We blog about:
SOA, BPM, EDA, ECM and all the other buzz words. Beware some post might not be so common as you think. We are not scared to go against main stream thoughts.
Technologies like java, maven, springframework, OSGi and front end technologies and frameworks like jQuery, DWR, Flex.
Finally to make this happen we need tools and of course a Mac (well some of us do). So we blog about that as well.
Linked in We now have a linked in group, join the group if you are a regular reader and want to see who else reads this blog.

Last Thursday (July 22nd, 2010) Rob Pike, a Principal Engineer at Google, gave a talk at the O’Reilly Open Source conference. In this talk he stated that established languages such as C++ and Java are too complex and not adequately suited for today’s computing environments. He then proceeded with some criticism of dynamically typed languages (that I share) and finally ended up plugging the Go language (which he co-developed) as a solution to the problem.
Now, Rob Pike is not nobody (in addition to being a Google principle engineer he has C and Unix credentials), plus the Go language has the Google brand name on it, so I thought it would be a good idea to check it out….

In my previous post, “Using JMX within a spring application“, I talked about monitoring your application with jmx. I discussed exposing beans with spring. At one of my current projects I am having problems exposing jmx through the default jmxrmi protocol. In his whitepaper about jmx, Allard mentiones another protocol, jmxmp. Spring has support for this remoting protocol as well. Therefore I wanted to try this out.
Another thing I wanted to experiment with is creating a groovy client. The technique with interfaces and proxies with spring as described in my previous post is a lot of work when you are interested in a little bit of data. Therefore I wanted to see if using groovy is easier.
This blog post discusses these two topics with respect to JMX.

I have just upgraded the wordpress software to version 3. It all seemed to work fine. However I noticed errors in the archive pages. Therefore I wanted to upgrade to the latest and greatest atahualpa theme that I use for my blog. I should not promote it to much, or else everybody else starts using it  .
To my opinion, the blog looks even better. The twitter items look better than before as well as the authors with the amount of blog items.
If you spot problems, please let me know.

Lately I have been doing a lot with JMX. I use it more and more to check what my application is doing. I use it to monitor tomcat, the cache, queue’s and other libraries and components. Now I wanted to use jmx to monitor my own application. Using the standard JMX stuff coming with the JDK is not hard, but since I use a lot of spring, I wanted to know more about spring support.
The most important question in the end will be, is it easier to use spring with jmx than the standard jmx stuff from the jdk.
Read on to find out about jmx and my answer to the question which is easier, the spring way or the standard jmx way.

 Today, I finalized the 0.5 release of the Axon Framework. There is quite a number of changes since the 0.4 version. The 0.5 version is a major step towards production readiness of the framework.
Besides some changes to existing building blocks, such as the event bus, which is now much more powerful, the 0.5 version also includes some new features.
Read on to find out more.

In this post we focus on getting the task based user interface. We have the basic building blocks in the application, but the screens are a bit stupid. How many applications would you create where you have to manually copy the identifier of a contact to an address when you want to register an address for this contact. Well in the current version of the application this is what you really have to do.
What are the tasks that we focus on right now:
- Create a new contact
- Remove a contact
- Change the name of a contact
- Register an address of a certain type for a specific contact
- Remove an address from a contact
But before we step into creating the front-end, we install some plugins that I discussed in previous posts.

Some people have asked be what I was working on lately, since they didn’t see any blogs from me the last months. Well, my life has been heavily focused on the investigation of all the capabilities of a very simple pattern: CQRS. As I unleashed its power on a project, I noticed that most of it is quite generic. That was my trigger to build the Axon Framework, a CQRS Framework for Java.
Read on to find out more…

I have blogged before about the flex client I have created for the Axon framework addressbook sample project. If you did not read it before and want to learn more about the parsley framework, check this blog.
http://www.gridshore.nl/2010/02/25/creating-a-sample-for-axon-using-flex-and-parsley/
In this blog item I am describing changes based on a new feature made available in Axon. Allard has created support for a CommandBus and command handlers. Basic idea is that you dispatch items on the bus, and a registeredhandler picks it up and handles it. This makes the command query separation also more clear on the flex side of the application.
