Here’s the updated FAQ. Short summary: Oracle plans to keep and invest in all Sun products such as: Netbeans, Glassfish, MySQL, VirtualBox, and OpenOffice.

A simple file monitoring console with camel, cometd and jquery

October 27th, 2009  |  by akoelewijn  |  published in oss, soa, web

Here’s a simple file monitoring tool which uses cometd to push file changes to a webpage.
The server part consists of a groovy script which uses Apache Camel to monitor some files. It then uses Apache Camel to push the lines added to the files to the browser with Cometd. In the webpage a bit [...]

US DOD guidance on open source surprisingly correct

October 27th, 2009  |  by akoelewijn  |  published in oss

I always surprises me what people think open source means and what impact it has on their organization: Open Source means gratis software. Open Source is made by hobbyist. Open Source is unfinished because it doesn’t have a 1.0 version. We can only use the binaries released by the Open Source organization.
Imagine my surprise when [...]

SOA needs Services and Resources

October 24th, 2009  |  by akoelewijn  |  published in open standards, soa

Stefan Tilkov blogged on the recently created SOA manifesto. He’s a big proponent of using REST(ful HTTP) for achieving SOA goals. One of the reactions he got on a previous post on this topic states that REST and SOA are incompatible, as REST is not about services but about resources or documents (with a standardized [...]

Unit test Mule mail endpoint using wiser smtp server

October 21st, 2009  |  by akoelewijn  |  published in oss, soa

Here’s a quick example (thx enno) how you can unit test an smtp endpoint in Mule using subethasmtp Wiser.
We’ll start by creating a new mule project using maven:

mvn mule-project-archetype:create -DgroupId=nl.iteye \
-DartifactId=mule-mail -DmuleVersion=2.2.1 -Dinteractive=false \
-Dtransports=smtp,vm -Dmodules=

If you have problems with dependencies when you run mvn compile, here’s a blog post that will [...]

Response transformers on Mule outbound endpoints

October 18th, 2009  |  by akoelewijn  |  published in oss, soa

A coworker found a message on the mule-user mailing list that said that you have to apply response transformers on inbound endpoints, not on outbound endpoints. Sounds a bit weird to me, at least not very intuitive. Time for a test.

Here’s the mule config:

<mule xmlns="http://www.mulesource.org/schema/mule/core/2.2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Everything will be mobile

October 18th, 2009  |  by akoelewijn  |  published in Uncategorized

I’m personally convinced that within a few years 80% or more of all web access will be from mobile devices: Phones, or tablets. Most people only use their computers to read mail and surf the web. Once this can be done conveniently on mobile devices, these people will have no use for a laptop of [...]
