Thanks for your answer.
I've already tried that but it doesn't work.
I look at the source code and the called method don't seem to search in
the report engine classloader...
org.eclipse.birt.report.model.api.DefaultResourceLocator.getResource(
ModuleHandle moduleHandle, String fileName )
tries to find .properties file in the resource path with a "disk file"
search and an "URL search" only.
It also look into the "org.eclipse.birt.resources" fragments classloader...
What I want to know is if there is simple way to internationalize report
than creating a fragment or a new IResourceLocator...
Thanks.
