<h2>EntityBean</h2>
<h3>Description</h3>
<p>
Checks that a direct entity bean, i.e. a class that directly
implements <span class="code">javax.ejb.EntityBean</span>,
satisfies these class requirements:
</p>
<ul>
<li>
The class is defined as <span class="code">public</span>.
</li>
<li>
The class cannot be defined as <span class="code">final</span>.
</li>
<li>
It contains a <span class="code">public</span> constructor with no
parameters.
</li>
<li>
It must not define the <span class="code">finalize</span> method.
</li>
</ul>
<p>
Checks that methods of a direct entity bean satisfy these
requirements:
</p>
<ul>
<li>
All <span class="code">ejbCreate<METHOD>(...)</span> methods
are <span class="code">public</span>, not <span class="code">final</span>, and not <span class="code">static</span>.
</li>
<li>
The return type of all <span class="code">ejbCreate<METHOD>(...)</span> methods is not
<span class="code">void</span>, because the return type must be
the entity bean's primary key type.
</li>
<li>
All <span class="code">ejbPostCreate<METHOD>(...)</span>
methods are <span class="code">public</span>, not <span class="code">final</span>, and not <span class="code">static</span>.
</li>
<li>
The return type of all <span class="code">ejbPostCreate<METHOD>(...)</span> methods is
<span class="code">void</span>.
</li>
<li>
For each <span class="code">ejbCreate<METHOD>(...)</span>
method there is a matching <span class="code">ejbPostCreate<METHOD>(...)</span> method.
</li>
<li>
All <span class="code">ejbHome<METHOD>(...)</span> methods
are <span class="code">public</span>, and not <span class="code">static</span>.
</li>
<li>
The throws clause of all <span class="code">ejbHome<METHOD>(...)</span> methods does not
define the <span class="code">java.rmi.RemoteException</span>.
</li>
</ul>
<p>
When the check is configured to check direct entity beans as having
bean-managed persistence, checks that methods satisfy these
additional requirements:
</p>
<ul>
<li>
All <span class="code">ejbFind<METHOD>(...)</span> methods
are <span class="code">public</span>, not <span class="code">final</span>, and not <span class="code">static</span>.
</li>
<li>
The return type of all <span class="code">ejbFind<METHOD>(...)</span> methods is not
<span class="code">void</span>, because the return type must be
the entity bean's primary key type, or a collection of primary
keys.
</li>
<li>
There is a <span class="code">ejbFindByPrimaryKey</span> method
with one parameter.
</li>
</ul>
<p>
When the check is configured to check direct entity beans as having
container-managed persistence, checks that methods satisfy these
additional requirements:
</p>
<ul>
<li>
The throws clause of all <span class="code">ejbCreate<METHOD>(...)</span> methods defines
the <span class="code">javax.ejb.CreateException</span>.
</li>
<li>
All <span class="code">ejbSelect<METHOD>(...)</span> methods
are <span class="code">public</span> and <span class="code">abstract</span>.
</li>
<li>
The throws clause of all <span class="code">ejbSelect<METHOD>(...)</span> methods defines
the <span class="code">javax.ejb.FinderException</span>.
</li>
</ul>
