[jboss-user] [JBoss Seam] - Re: Questions about injection and outjection

[y_zl]

1) If the answer to question one is Yes, does it mean that it will inject non-relevant variables as well? Does it affect performance ?
2) For question 2, If I have two session beans A and B. B is used as a session facade.

      
  |      @Stateless
  |      @Name("a")
  |      public Class A ...{
  |            @In B b;
  |            public String test1()
  |             {
  |                    return b.test2("cccc");
  |              }
  |       }
  | 
  |      @Stateless
  |      @Name("b")
  |       public Class B ...{
  |              @In String s1;
  |              @Out String s2;
  |              public String test2(String s)
  |             {
  |                   s2=s+"aaaa";
  |                   return s+s1;
  |              }
  |        }

      is the above codes legal ? Could I get the variable named s2 outjected?

3) For question 3, Could you give a simple example to demo that? 

   For example 
   
  |    @Stateless
  |    @Name("actionA")
  |    public class ActionA implents ActionAInf {
  |         @PersistenceContext                                                                
  |          private EntityManager em;
  | 
  |         public String methodA()
  |         {
  |                new Bean(em);                            
  |         }
  |      }
     How do I use the EL binding in this case?
