Valentin Crettaz's cheat sheets

Hi Valentin,

I used your cheat sheets and found them very useful
Just a little curiosity (more than a question since I already passed the exam last week ) :
In the http://www.valoxo.ch/jr/BeanProviderResponsibilities.pdf file , basically your ejbcreate() , activate().. etc methods from the SessionBean or EntityBean interfaces , declare a RemoteException in their throws clause.
If I remember right , you cannot ever throw a RemoteException from within your Bean code.
Is this correct or I�m missing something ?

Hi Victor,

I'm glad you found my cheat sheets useful. As for the RemoteException thing, only the following methods MUST NOT declare it:
- ejbCreate, ejbPostCreate, ejbHome, ejbSelect and the business methods of entity beans
- ejbCreate, and business methods of session beans

An if you look at the EntityBean and SessionBean API, you'll see that all methods have RemoteException in their throws clause even though their use is deprecated. I will probably remove them on the cheat sheets soon. Thanks for the feedback.

Hope this helps

Can we have ejbActivate & ejbPassivate declared to be throw RemoteException.
