I am trying to have Jboss (4.2.2) and hibernate work together with JTA. I deploy my hibernate classes via a .har file. I've seen this issue mentioned in some threads, but never resolved. I feel like I am just missing a simple setting or something. Any help would be appreciated. I have great success using the following: ctx = new InitialContext(); factory = (SessionFactory)ctx.lookup("java:/hibernate/SessionFactory"); Session hSess = factory.openSession(); Transaction tx = hSess.beginTransaction(); But I cannot get the following to work: Session hSess = factory.getCurrentSession(); The error thrown is: org.hibernate.HibernateException: Unable to locate current JTA transaction at org.hibernate.context.JTASessionContext.currentSession(JTASessionContext.java:61) at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:544) at test.TestServlet.processRequest(TestServlet.java:57) at test.TestServlet.doGet(TestServlet.java:129) at javax.servlet.http.HttpServlet.service(HttpServlet.java:690) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.authenticator.SingleSignOn.invoke(SingleSignOn.java:393) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:595) Obvously no transaction is obtained from the TransactionManager, but why?
