<div class="jive-rendered-content"><p>Is there a way to dinamically switch EntityManager's DataSource to working with more then one datanase? For this time I found only way described here:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><a class="jive-link-external-small" href="http://">http://community.jboss.org/message/356772</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><em>"<a class="jive-link-email-small" href="mailto:bill.burke@jboss.com" target="_blank">bill.burke@jboss.com</a>" wrote:<br/>deploy your entities as you would but assign them a JNDI name(see docs). In your EJB interceptor pick the appropriate JNDI name of the EntityManager you want to access. Either inject the ENtityManager into the field of your bean using a custom annotation, or stuff the chosen entity manager into a java.lang.ThreadLocal. This way you still get the automatic session management that the EJB/Java Persistence integration gives you. Following me?</em></p></div>
