Home methods

[Dan T]

We arent allowed to get a reference to EJBObject or get primary key in Home methods because the bean has no EJBObject (they are inside the pool).

What would happen if we called create() / findByPrimaryKey(..) on the home interface, then try to get a reference to those? Might be a meaningless thing to do, but would it return the references?

Here Home Methods mean Home Business Methods. Home business methods can be used by any ejbs.

create and findByPrimayKey will return EJBObject references.

Hope it helps

Maybe my question was not clear.

Things you can do in your Home Business methods:
- getEJBHome
- getEJBLocalHome
- isCallerInRole(..)
- getCallerPrincipal
- setRollBackOnly
- getRollBackOnly
- JNDI env
- access other beans
- Resource manager

Hence we are not allowed to call getEJBObject() and getPrimaryKey() on the EntityContext because there is not an EJBObject associated with the bean (it is in the pool). What if we called the create() or findByPrimaryKey() method before invoking the getEJbObject in the home business? Calling these methods will either create and find an EJbObject, so will it return the references in the home methods?

It's going to throw illegalStateException since there is no EJBObject associtated with the entitycontext.
