java.lang.NoSuchMethodError : org.hibernate.Session.connection()Ljava/sql/Connection;
I'm trying to do some operation when process is created using ProcessEventListener in jBPM 6.1.0 version. However, when i fire some query using simple jdbc connection. it throws above exception. when i googled for this exception, It turns out that it is a known issue - https://jira.spring.io/browse/INT-2693
Can i use Hibernate 3.x and JPA for jBPM 6.1.0 version?
jbpm 6 is based on JPA 2 which is then hibernate 4.2.x used by default. So recommended approach is to use version of hibernate jbpm was tested with or at least one that supports JPA2.
