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.

On my employers blog I wrote a piece about a new feature of Hippo called pipelines that can be used to create new content channels. We have created an rss feed using the standard components of Hippo combined with the Rome project. If you are interested you can read the blog post here:

 Hippo is an opensource content management system. Hippo has created a cms on top of the Jackrabbit repository. Hippo is not the only cms that does this trick, but it is a big one. With version 7 out there, you can now use some nice features that they have created. This post discusses one of these features in detail, Workflow. I’ll explain what it is, what is can be used for and how you can extend it with business events.
I do want to stress that this is an idea I have about how this can be implemented. I did try it out, but do not consider this as a best practise (yet). See it as inspiration to your own extensions and maybe Hippo will contain something like this in the future.
The idea behind this post came from talks with Allard and Jeroen Reijn, who will write a blog post about a specific part of the solution as I will describe in the post later on.

 Since my last article about springframework and hippo “Roadtrip from springframework to hippo 7” I have made a lot of changes to the code and moved my project to the hippo forge. With this post I want to explain what I have changed and in some situations why. I will not repeat the stuff I already talked about in the previous post. One of the biggest areas I made changes in, is the stability of the solution. I used the Circuit Breaker implementation as discussed by Allard in his post “Bring some stability to your architecture“. Stability comes with reconnect options and a component that guards the repository. In case of to many errors the connections are closed and after a certain cool down period, new connections are created.
One remark I like to make is about the connection pool. This pool is probably not production ready. I did not do any performance tests and it is a bit rough around the edges.
That said, let’s move on and start talking about the solution.

 At the moment I am doing a proof of concept for a customer together with two developers from the customer and a developer from Hippo. We are using the future product of hippo, Hippo 7. It is a nice technology stack using JackRabbit for the content repository and wicket as a view technology for the cms. The guys from Hippo are working very hard to come up with the first release of Hippo 7. This release has been rebuild from the ground up. One of the requirements for the project is a webservice that accesses the hippo repository and returns some information from the repository. That is what this post is about.
This post will talk about connecting to the hippo repository using the spring framework. I’ll show a very basic (not production ready) connection pooling into the repository. Using this connection, the spring webservices project will step in and take over. Using spring-ws I am exposing a search into the documents.
Feel free to post a comment if you have questions, the sources are again available on google code.

This article is about integrating the hippo cms with a spring framework application. To be honest, the amount of integration is very easy if you know how to configure the api that is provided by hippo. So what are we going to do? In this article I am going to describe the high level architecture of a normal spring-mvc application that makes use of the hippo api to store and obtain content from the hippo content repository.
For this article I have made use of the hippo 6 version. Things might change a lot when you are dealing with hippo 7. Starting release 7, hippo is fully compliant with the Java Content Repository API.
