how to add @SecurityDomain package

[icey.xiong]

Dear All,

         I want to to use Jboss Authorization with @RolesAllowed and @SecurityDomain ,like this:

@Stateless
@SecurityDomain("JbossDomain")                      ---  error,can not find the annotation
@public class Test
{
     @RolesAllowed("admin")
     public void doOnly()
         {
               System.out.println("it`s can be called by admin");
          }
}

I know @SecurityDomain in package jboss-ejb3-ext-api-2.0.0-beta-1.jar, after I add the jar file into build path,it can still can not find the annotation class. o,I am using Jboss 7.0.2  final version.

someone knows anything about this?how can I add that jar into my project ? thank you very much!
