<DL>
<DD>This method corresponds to the create method in the home interface
 "AccountHome.java".
 The parameter sets of the two methods are identical. When the client calls
 <code>AccountHome.create()</code>, the container allocates an instance
 of this bean and calls <code>AccountBean.ejbCreate()</code>.
 <p>
 For bean-managed persistence, <code>ejbCreate()</code> returns
 a primary key, unlike the case of container-managed
 persistence, where it returns a void.
