ejbSelect and findBy method

[eric138]

Hello,


Would you please to tell me when should use ejbSelect and findBy in EJB ?


Best regards,
Eric

ejbFindBy returns primary key(s) of the
entity bean. It is the implementation of findBy
in the home interface and can be used by clients
to obtain bean proxies. The container turns the
primary keys into remote/local interface implementations.

e.g.

MyRemote bean = home.findByNickName("eric138");

ejbSelect can return any type of bean
(not necessarily the same entity where it is defined)
or cmp-field. The entity uses it internally.

e.g.

Collection emails = bean.getEmails(Date date);

// Get the user's e-mails for a date
public Collection getEmails(Date date)
{
return ejbSelectEmails(date);
}

Regards,
Adrian
