I have done upgrade from Hibernate 3.6 to Hibernate 4.2 and Java 7 to Java8. before upgrade it was working fine, now I'm facing issue with two java files
Session tempSession = HibernateUtil.getSessionFactory().openSession(conn); i'm not able to pass conn object to openSession method.please find the below code. pls provide some ideas or solution wherther i need to miss jars or deprecated??
this error is i got on sts spring tool
1.The method openSession() in the type SessionFactory is not applicable for the arguments (Connection) -- AuditLogUtil.java
2. The method openSession() in the type SessionFactory is not applicable for the arguments(AuditLogInterceptor--HbernateUtil.java
