Trond Andersen has a post on Integration Severs here. He’s not sure if the way they work is a good or bad thing, and I’m not sure either. I like to stay in OO land as much as possible.

I’m not really sure when an Integration Server would be a good solution. It seems to me it is on it’s way to become a bit over used. With adapters to legacy systems I can see the need, and it might reduce the time it takes to integrate these with new solutions.

In most cases it will be just as easy to set up systems for direct communication. In some cases you could argue a Integartion Server provides loose coupling, but I honestly don’t see how it makes looser coupling just because you got JMS/WS/XML going over the wire. Just another thing I should have a peek at. 😉

Matt Raible has a post about his experience with Ajax using DWR and Spring here. The demo video looks really slick, and it seems he has mostly good experiences with this. As always I’m concerned with the cross browser and maintainability stuff, but I havn’t really looked into how to handle this. I might look into trying some small snippets with DWR, I guess you can offload most of the work to the server, and do some pretty simple stuff in JavaScript to avoid most browser issues.

There’s an article about SiteMesh here.

I haven’t tried it out yet, but I’ll my sure to include it in my test project. I’m currently doing a small project to test new ideas and products. Many of the ideas I’m exploring is based on the excellent Domain Driven Design book by Eric Evans.

Products on my test schedule include:

• Hibernate 3
• Spring Framework
• Spring WebFlow
• SiteMesh

Finding a good domain model, combining it with good products and using the products correctly is a hughe challenge. I hope I’ll get it mostly right one day. 😉
