Hi,  
I downloaded and tested using the openehr-rm-core from

[http://www.openehr.org/svn/ref\_impl\_java/TRUNK/docs/download.htm](http://www.openehr.org/svn/ref_impl_java/TRUNK/docs/download.htm)

It appears that this requires packages Apache Commons to work.  
Perhaps this should be mentioned on the download page?

Regards

Olof

Hi Olof,

All the Java components from the openEHR Java project are managed by Maven, which means the dependency to external libraries are declared and maintained in the pom file at the top directory of each component.

By the way, if you want to build from the latest source from the trunk, follow the instructions from the quick-guide, [http://www.openehr.org/wiki/display/projects/Quick+start+guide+for+the+openEHR+Java+project](http://www.openehr.org/wiki/display/projects/Quick+start+guide+for+the+openEHR+Java+project).

Cheers,  
Rong
