<div class="jive-rendered-content"><p>Hi all,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am trying to build a persistent archive (Hibernate 3.5 as JPA provider) containing entities that should be usable in different applications.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My first use case is a web application running in a standalone Tomcat 5.5 environment. The JNDI reference to the datasource in the persistence.xml for that environment must be relative to the JNDI ENC, e.g.:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-xml"><span class="jive-xml-tag"><jta-data-source></span>java:/comp/env/jdbc/MyDatabase<span class="jive-xml-tag"></jta-data-source></span></code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>My other use case is an enterprise application for JBoss 6. The JNDI reference to the database in my JBoss deployment is e.g. java:/MyDatabase</p><p>If I use the persistent archive with the same persistence.xml as in my first use case the datasource can not be found.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>How can I override the reference to the datasource without changing the persistent archive?</p><p>Or is it possible to create a link in JNDI?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I tried to remove the persistence.xml from the persistent archive (located in ear/lib) and created a new persistence.xml in my ear referencing the persistent archive by using the jar-file element and the datasource java:/MyDatabase. That works in JBoss 6, but I do not know how to deploy that in Tomcat 5.5. The corresponding method by usign the jar-file element does only work in Tomcat by using an absolute path for the persistent archive what I do not prefer.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Can anyone help?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks,</p><p>Gonne</p></div>
