here part of student.java , studentenrollmentservlet class.

@named(student.named) public class student {       public static final string named = "student";      .......  }  @named(studentenrollmentservlet.named) public class studentenrollmentservlet extends httpservlet {      public static final string named = "studentenrollmentservlet";       @resource(name = student.named)     private student student;      @override     protected void doget(httpservletrequest request, httpservletresponse response)                      throws servletexception, ioexception {          processrequest(request, response);     }      ....... } 

it looks need give bean name

@named("student")
