java - How to get a session Object in the ContainerRequest to can use the annotation @RolesAllowed(Role_user)? -

-

i building application using app engine jersey. use annotation @rolesallowed(role_user) permit create filter in request.

the problem need configure class securitycontextfilter.

my objective id of user stored in session check role directly in function : public containerrequest filter(containerrequest request) of class securitycontextfilter.

i need inject httprequest session, when inject exception java.lang.null.

i want session object in class containerrequest.

how can this?

edit:

i have find solution issue don't know if clean: can inject httprequest directly in function : isuserinrole(_role) use , userid session role user , check if match _role , return true or false.

i'm pretty not sure whether can inject httpservletrequest on top of containerrequestfilter in jersey still can programmatically instead of using annotations:

@override public containerrequest filter(containerrequest request) {     if(request.isuserinrole("some_role")){     //process treatement     }     return request; }

br.
