Recource injection doesn't work with glassfish 4 while lookup works

问题

I use resource injection in my application scope managed bean with glassfish 4, but glassfish failed to work and using the default derby database instead. there is my code:

@Named(value = "dbManager")
@ApplicationScoped
public class DbManager {
  @Resource(name = "jdbc/mydb")
  private DataSource ds;

// but lookup method works

 ctx = new InitialContext();
 ds = (DataSource) ctx.lookup("jdbc/mydb");

I can't find the reason for this.

回答1:

try this

 @Resource(mappedName = "jdbc/mydb")

instead of this

 @Resource(name = "jdbc/mydb")

It works for me on glassfish 4. :)
