Hi,
During the creation of my EJB the following error occur :
I have this method :
Long ejbCreate() {
return null;
}
I have several realted questions :
- Do I need to return a key ?
- Can I use AutoNumber in my database
- If I do not use AutoNumber and I m unable to give a key, does JBoss will
generate one for me ?
