The first bean is a standard EJB3.0 webservice bean.
| @WebService(name = "Reference", serviceName = "Reference", targetNamespace = "http://legion.ccf.org";) | @SOAPBinding(style = SOAPBinding.Style.DOCUMENT) | /* | * JBOSS specific security annotations | */ | @SecurityDomain("tactus-domain") | @WebContext(authMethod = "BASIC", contextRoot = "/Legion/Ref", transportGuarantee = "NONE", secureWSDLAccess = false) | | | | @Stateless(name = "Reference") | @Remote(Reference.class) | @Local(Reference.class) | @TransactionManagement(TransactionManagementType.BEAN) | @Interceptors(TrackingMetrics.class) | public class ReferenceWebBean implements ReferenceWeb | { | protected AdapterRegistry registry = null; | protected ReferenceWeb adapter = null; | | | /* (non-Javadoc) | * @see org.ccf.legion.ReferenceWeb#getUserRoles() | */ | @Override | public List<String> getUserRoles() | { | return adapter.getUserRoles(); | } | } | The adapter object is a simple POJO used to do work. It uses the following code to find the second bean using the JNDI string "Legion/ReferenceBean/local". The ReferenceWebBean (EJB3.0 #1) is a web service bean and calls other beans to do it's work. The ReferenceBean (EJB3.0 #2) is a stateless EJB bean which accesses the database. | private Object findJNDIResource(String mappedName) | { | Object result = null; | | try | { | InitialContext context = new InitialContext(); | result = context.lookup(mappedName); | } | catch (NamingException e) | { | log.debug(messages.getString("AdapterRegistry.24", mappedName)); | // if not found just return null | } | | return result; | } | After getting the local inteface to the ReferenceBean (EJB3.0 #2) the adapter calls a method on that bean which then does the following: | public List<String> getRoles() | { | List<String> rolelist = new java.util.ArrayList<String>(); | | Subject subject = org.jboss.security.SecurityAssociation.getSubject(); | if(subject == null) | { | log.debug("Subject is null"); | return rolelist; | } | | Set<SimpleGroup> groups = subject.getPrincipals(SimpleGroup.class); | if(groups.isEmpty()) | log.debug("No Simple Groups"); | else | { | for(SimpleGroup group : groups) | { | if(group.getName().compareToIgnoreCase("Roles")==0) | { | java.util.Enumeration<?> en = group.members(); | while(en.hasMoreElements()) | { | Object obj = en.nextElement(); | if(obj instanceof Principal) | { | String name = ((Principal)obj).getName(); | rolelist.add(name); | log.debug("Role name = "+name); | | } | else | { | log.debug("Simple Group Content: " + obj.getClass().getName()); | } | } | } | } | } | | return rolelist; | } | | If I put the above code directly in the webservice bean (ReferenceWebBean or EJB3.0 #1) it works, and returns the roles list. If I put this code in the second EJB3.0 bean (ReferenceBean EJB3.0 #2) where the database connections are then it returns a null for the Subject. These two beans are in the same EAR file, but different JAR files. The second EJB3.0 bean (ReferenceBean EJB3.0 #2) looks like this: | @Stateless(name = "ReferenceBean") //$NON-NLS-1$ | @Remote(Reference.class) | @Local(Reference.class) | @TransactionManagement(TransactionManagementType.BEAN) | @Interceptors(TrackingMetrics.class) | public class ReferenceBean extends LegionServiceSupport implements Reference | { | private static final Log log = LogFactory.getLog(ReferenceBean.class); | private static final Messages messages = Messages | .getMessages(ReferenceBean.class); | | | @PersistenceContext(unitName = "LegionModel") //$NON-NLS-1$ | private EntityManager manager = null; | | | | | I hope that helps explain what's going on. The codes a bit more involved than what I've shown, but these are the relevant parts.
