You will have to specify that jar and related in the deployment classpath: | | <classloader><inject bean="JBossSXClassLoader"/></classloader> | | <bean name="JBossSXClassLoader" class="org.jboss.system.NoAnnotationURLClassLoader"> | <classloader><null/></classloader> | <constructor factoryClass="org.jboss.system.NoAnnotationURLClassLoader" factoryMethod="createClassLoader"> | <parameter> | <array elementClass="java.net.URL"> | <!-- Deployers --> | <value>${jboss.server.lib.url}/jbosssx.jar</value> | </array> | </parameter> | </constructor> | </bean> | ... | This is a brute force configuration. There should be a way to specify the class loader system that includes all the server libs as well as just naming the packages you want to import. We need to get that syntax documented.
