Mule ESB set up with Maven under Eclipse (OSX)

January 22, 2010 2 comments

I have followed the Mule ESB tutorial and found that it did not work with Java5 on OSX. I have switched to Java6 and everything was back to normal.

Everything is explained very well on Mule web site, here is what I did to get it running with Maven 2 under Eclipse on OSX.

Firstly I have of course downloaded Mule (community edition) on their download page and expanded everything in /opt folder with the following command:

tar -xvzf mule-standalone-2.2.1.tar.gz

I’ve also downloaded the mule ide plugin for eclipse and followed the instructions here

To get it running with Maven, I used the command line in my project folder :
mvn mule-project-archetype:create -DartifactId=MMuleProject -DmuleVersion=2.2.0

and then I have the following command:
mvn eclipse:eclipse

to make it available as a project in eclipse.

Then I have launched Eclipse and imported the project:

File->import->Existing project into workspace

and I have selected the MMuleProject folder as root folder. Once the project was imported i have right-clicked on the project name MMProject in the package explorer and added Mule libraries:

project properties under eclipse

the project finally appears like the following inside the package explorer:

With Java 5 enabled I had this issue when trying to run the project : (right-click on mule-config.xml -> run as -> Mule Server)

Switching to JDK 6 solved it :

pheeewww… it should have taken a few minutes, it took a few hours to figure out I should not use JDK5. Now I’ll experience this lightweight SOA architecture to expose SOAP web services. Something for a next post.
