<div class="jive-rendered-content"><p>In JBoss 5.1 I was able to have an ejb-jar.xml that referenced a system property for setting the maxSessions for an MDB. But in JBoss AS 7, if I use a variable the setting is not applied.</p><p>This is a problem as the ejb-jar.xml is compiled into the ear file, and I need to be able to set this value as runtime. Is there a way to set the maxsessions for an MDB in jboss as 7 at run time?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>e.g. working config in jboss 5.1:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span><ejb-jar xmlns="</span><a class="jive-link-external-small" href="http://java.sun.com/xml/ns/javaee" target="_blank">http://java.sun.com/xml/ns/javaee</a><span>" xmlns:xsi="</span><a class="jive-link-external-small" href="http://www.w3.org/2001/XMLSchema-instance" target="_blank">http://www.w3.org/2001/XMLSchema-instance</a><span>"</span></p><p><span>          xsi:schemaLocation="</span><a class="jive-link-external-small" href="http://java.sun.com/xml/ns/javaee" target="_blank">http://java.sun.com/xml/ns/javaee</a><span> </span><a class="jive-link-external-small" href="http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" target="_blank">http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd</a><span>"</span></p><p>          version="3.0"></p><p>          <description>Deployment descriptor</description></p><p>          <enterprise-beans></p><p>                    <message-driven></p><p>                              <ejb-name>WorkerMdb</ejb-name></p><p>                              <messaging-type>javax.jms.MessageListener</messaging-type></p><p>                              <message-destination-type>javax.jms.Queue</message-destination-type></p><p>                              <activation-config></p><p>                                        <activation-config-property></p><p>                                                  <activation-config-property-name>maxSession</activation-config-property-name></p><p>                                                  <activation-config-property-value><strong>${worker.threads:8}</strong></activation-config-property-value></p><p>                                        </activation-config-property></p><p>                              </activation-config></p><p>                    </message-driven></p><p>          </enterprise-beans></p><p></ejb-jar></p></div>
