MuleCast: A Conversation with the creator of the JCR Transport

In this episode, MuleSource CTO and co-founder Ross Mason speaks with David Dossot, creator of the JCR transport for Mule.  The JCR transport reads from, writes to, and observes JCR 1.0 containers.  Mule users can find a user guide and examples for using the JCR transport with Mule 1.4.x on the MuleForge – the user guide and examples for Mule 2.1.x are in the works now.

Mule IDE “Christmas” snapshot release

December 23 2008


I was able to squash some bugs on the IDE since the last snapshot release.

The first bug was related to creating new projects with a non-default Mule distribution. If you have more than one Mule distribution registered in our Mule IDE preferences, you can choose the runtime to use when creating a new project and the project will refer to the proper jars.

Writing a Mule Transformer, Part 2

December 12 2008


Last week I posted about Writing Mule Transformers, this week I’m going to continue with some more advanced features users can take advantage of.

All objects in Mule have lifecycle associated with them. Lifecycle calls can be added as necessary. For transformers, there are two lifecycle methods that are most useful.

By default the AbstractEventAwareTransfromer and AbstractTransformer both implement the org.mule.

Mule Tales

December 9 2008


One of the great things about working on Mule is hearing the amazing tales of what people are doing with it. I’ve heard Mule referred to as a “Swiss army knife of integration” because of its flexibility and number of supported service topologies and technologies. While some case studies are available online from large implementations, I am very interested in hearing about the smaller successes people have had using Mule.

Webinar: Make Web Applications do more with Mule


I will be presenting a webinar tomorrow Dec. 9th at 9 AM PT/ Noon ET covering integration between Mule and webapps. It will be a technical walk-through of an example application consisting of two webapps consuming Mule services, one with Mule running inside it. The audience is assumed to have some prior experience developing with webapps and/or Mule.

A bit of history
We created Mule IDE to ease the work when developing with Mule. Along with the work on Mule 2.0 we started work on an updated version of the IDE that would allow you to graphically design Mule configurations. This turned out to be by far more work than initially expected so we decided to rescope the work. Right now we focus on the little helpers that make developing with Mule easy and cut out the graphical editor for now.

Writing a Mule Transformer

Transformers in Mule are simple objects that convert the current message from one type to another. The interface for a transformer is simple, but there are some tips and tricks for getting the most out of transformers. For this post we will define a transformer the converts from an Order object to HTML so that we can email the details of an order to a customer.
