The Deployment error for the war ------- ERROR [org.jboss.web.tomcat.service.deployers.TomcatDeployment] (ResourceContainer.invoker.nonDaemon-3) ENC setup failed java.lang.NullPointerException     at org.jboss.injection.PersistenceUnitHandler.getEntityManagerFactory(PersistenceUnitHandler.java:172)     at org.jboss.injection.PersistenceUnitHandler.getFactory(PersistenceUnitHandler.java:163)     at org.jboss.injection.PuEncInjector.inject(PuEncInjector.java:54) ------- 2. sda.war uses  r MS SQL Server Datasource on a Windows platform connecting to SQL Server using Integrated Authentication, The driver sqljdbc4.jar loads the appropriate sqljdbc_auth.dll in the JVM library path from <JBOSS_HOME>\lib (where JBOSS_HOME=E:\EnterprisePlatform-5.1.0\jboss-eap-5.1\jboss-as) 4. The driver and the Integrated Authentication are loaded fine  and the error has to do with the sda-ds.xml or the persistence.xml. Either specific type-mappings need to be specified in sda-ds.xml or specific jta-datasource properties needs to be added in the persistence.xml (sda.war\WEB-INF\classes\META-INF\persistence.xml) for both servicedeskappGlobalDatasource  and the sdaDatasource. 5. It used to work in EAP 4.3.0 CP03 and not on EAP 5.1.0 GA. Any assistance would be much appreciated.
