All,
Could anyone tell me diff b/w Component-managed Authentication & Container-managed Authentication Alias.

Thanks,

Componet managed authentication & Container manged authentiction are the secutiy setting for authenticating the resources.

In Component mangaged authentication, authentication can be done at components i.e what we defined at J2C authentication.

In Container manged authentication, authentication can be done at continer level and it will happen when absence of Component managed authentication.

As said by Gawtham, container managed authentication is handled at container level i.e you need to define J2C authentication aliases and select the authentication mode to be container managed.

In case of component managed authentication, I guess it is running application that supplies the credentials for login.

Hope this helps.
