    text
    copied!<p>Can one declare multiple beans in the <code>ejb-jar.xml</code> (<strong>in EJB 1.1</strong>) deployment descriptor with different names but the same classes behind?</p> <p>For example:</p> <pre><code>&lt;session&gt; &lt;ejb-name&gt;AccountFacade&lt;/ejb-name&gt; &lt;home&gt;com.something.ejb.AccountFacadeHome&lt;/home&gt; &lt;remote&gt;com.something.ejb.AccountFacadeRemote&lt;/remote&gt; &lt;ejb-class&gt;com.something.ejb.AccountFacadeBean&lt;/ejb-class&gt; &lt;session-type&gt;Stateless&lt;/session-type&gt; &lt;transaction-type&gt;Bean&lt;/transaction-type&gt; &lt;/session&gt; &lt;session&gt; &lt;ejb-name&gt;RestrictiveAccountFacade&lt;/ejb-name&gt; &lt;home&gt;com.something.ejb.AccountFacadeHome&lt;/home&gt; &lt;remote&gt;com.something.ejb.AccountFacadeRemote&lt;/remote&gt; &lt;ejb-class&gt;com.something.ejb.AccountFacadeBean&lt;/ejb-class&gt; &lt;session-type&gt;Stateless&lt;/session-type&gt; &lt;transaction-type&gt;Bean&lt;/transaction-type&gt; &lt;/session&gt; </code></pre> <p>For <code>RestrictiveAccountFacade</code> I want to set a higher isolation level in the <code>orion-ejb-jar.xml</code> file, something like:</p> <pre><code>&lt;entity-deployment name="AccountFacade" location="AccountFacade"&gt; &lt;resource-ref-mapping location="..." name="jdbc/..."/&gt; &lt;/entity-deployment&gt; &lt;entity-deployment name="RestrictiveAccountFacade" location="RestrictiveAccountFacade" isolation="serializable"&gt; &lt;resource-ref-mapping location="..." name="jdbc/..."/&gt; &lt;/entity-deployment&gt; </code></pre> <p>Is there a risk involved in doing this, any side effects or unspecified behavior? </p>
