When the EJB container needs to synchronize the instance variables of an entity bean with the corresponding values stored in a database, it invokes the ejbLoad and 
ejbStore methods. The ejbLoad method refreshes the instance variables from 
the database, and the ejbStore method writes the variables to the database. The 
client cannot call ejbLoad and ejbStore.

ejbLoad method: 
This method is called when it is necessary to synchronize the bean with data from the database. This will most likely trigger a SELECT to occur. The ejbLoad is triggered when the client requests to use the bean, forcing activation to happen, thus moving it to the ready pool. 
 
ejbStore method: 
This method is called when it is necessary to synchronize the bean data with the database. This will most likely trigger an UPDATE to occur. The ejbStore is triggered when the bean is no longer being used by a client, and the container decides to move the ready instance back into the pooled state.nullejbLoad method:ejbStore method:

Note: ejbLoad and ejbStore methods are to be coded only if you are creating a BMP. For CMP these methods are handled by the container.
