Hibernate Framework classes look for an HibernateSession with name "session" and that's a HttpSession ----------------------------------------------------------------------------------------------------- Key: JBSEAM-1708 URL: http://jira.jboss.com/jira/browse/JBSEAM-1708 Project: JBoss Seam Issue Type: Bug Components: Framework Affects Versions: 2.0.0.BETA1 Environment: Hibernate 3, Tomcat 6.0.13, Java 6, Windows XP Reporter: Ralph Schaer The Hibernate framework classes (HibernateEntityHome, HibernateEntityQuery) looking for a HibernateSession in the context with name "session". The problem is that "session" is already bound to a HttpSession. The result is that the program throws this exception Caused by: java.lang.ClassCastException: org.apache.catalina.session.StandardSessionFacade cannot be cast to org.hibernate.Session at org.jboss.seam.transaction.HibernateTransaction.initSession(HibernateTransaction.java:68) As a workaround I override the getPersistenceContext() in every Home and Query class @Override protected String getPersistenceContextName() { return "hibernateSession"; } components.xml looks like this. <persistence:hibernate-session-factory name="hibernateSessionFactory" /> <persistence:managed-hibernate-session name="hibernateSession" auto-create="true" session-factory="#{hibernateSessionFactory}" /> <transaction:hibernate-transaction session="#{hibernateSession}" /> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
