We are using RAD 7 + Websphere 7 app server and I was trying to use @Resource annotation to call a datasource from my EJB. when I used,

ic = new InitialContext();
dataSource=(DataSource)ic.lookup("jdbc/UPM");

it works fine!

but when I use,

@Resource(name="jdbc/UPMDbDs")
private DataSource dataSource;

it doesn't work. Should I do something more to use @Resource annotation and What can I do for this?

Error is:
