The only thing that I changed in the application I downloaded from www.mimuw.edu.pl/~barter/exampleear.zip is the definition of <mail:mail-session... in WEB-INF/components.xml. Now, I suspect that I need also to change some configuration in the Jboss itself. The seam references mention something about updating the file deploy/mail-service.xml (section 16.3.1.1) of the reference. But it didn't work for me Any help?
