@inject annotation throwing null pointer exception in Restful web service project

[Sachin Pachari]

i am using the following tutorial to build a web service project,

http://edwin.baculsoft.com/2012/04/beginning-rest-using-jboss-resteasy/

the above project works fine with the hard coded values that i am passing to the list in the service level,

but when i try to inject my class which will fetch values from the database then it throws null pointer exception, i have already added beans.xml, but still the injected class object is null.

i am not sure where i have gone wrong, any help will be appreciated.

thanks & Regards.
Sachin
