ejbRemove Method

A client deletes an entity bean by invoking the remove method. This invocation causes the EJB container to call the ejbRemove method, which deletes the entity state from the database. In theSavingsAccountBean class, the ejbRemove method invokes a private method named deleteRow, which issues a SQL DELETE statement. The ejbRemove method is short:
public void ejbRemove() {
    try {
    catch (Exception ex) {
        throw new EJBException("ejbRemove: " +
If the ejbRemove method encounters a system problem, it should throw the javax.ejb.EJBException. If it encounters an application error, it should throw a javax.ejb.RemoveException. 
An entity bean may also be removed directly by a database deletion. For example, if a SQL script deletes a row that contains an entity bean state, then that entity bean is removed.
