I believe my jboss-beans.xml, persistence.xml and components.xml files are correct. I now receive the following error: javax.faces.el.EvaluationException: Cannot get value for expression '#{usersList.firstResult}' | at org.apache.myfaces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:402) | ... | ... | Caused by: java.lang.IllegalArgumentException: EntityManagerFactory not found in JNDI | at org.jboss.seam.core.ManagedPersistenceContext.getEntityManagerFactoryFromJndiOrValueBinding(ManagedPersistenceContext.java:140) | ... | ... | | Caused by: javax.naming.NameNotFoundException: omegaDatasource not bound | at org.jnp.server.NamingServer.getBinding(NamingServer.java:529) | ... | ... Here is my components.xml file: <?xml version="1.0" encoding="UTF-8"?> | <components xmlns="http://jboss.com/products/seam/components" | xmlns:core="http://jboss.com/products/seam/core" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation= | "http://jboss.com/products/seam/core | http://jboss.com/products/seam/core-1.1.xsd | http://jboss.com/products/seam/components | http://jboss.com/products/seam/components-1.1.xsd"> | | <core:init jndi-pattern="#{ejbName}/local" debug="true"/> | | <core:manager conversation-timeout="120000"/> | | <core:managed-persistence-context name="entityManager" | persistence-unit-jndi-name="java:/omegaDatasource" | auto-create="true"/> | | | <core:ejb installed="true"/> | | </components> It seems that I do need to have an entity-manager-factory node for this to work on Tomcat. However, I have also noticed that if I take the 2 beans in my jboss-beans.xml file and put them in the embedded-jboss-beams.xml file, then I have fewer problems. However, according to the Seam documentation, this should not be necessary. -Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027344#...
