We have a restful web application built on Spring + Hibernate framework. It is using multiple datasources and transaction manager for each of the datasource is set as org.springframework.orm.hibernate4.HibernateTransactionManager. All these are chained together in org.springframework.data.transaction.ChainedTransactionManager. We are enabling transaction using <tx:annotation-driven transaction-manager="transactionManager" /> and @Transactional annotations. Now the problem is that in one of our modules we are facing an exception as soon as a few requests are made. The exception stack is given below. This module is not using the default transactionManager, so we have explicitly set which transaction manager to use in @Transactional(value=”<moduleSpecificTransactionManager”). Has anyone come across this issue and found a solution for it?
The version of hibernate and spring we are using are

hibernate.core.version - 4.3.11.Final
hibernate.annotations.versions - 3.4.0.GA
hibernate.validator.version - 5.1.1.Final
spring.version - 4.2.0.RELEASE

Looks like a Spring configuration issue. Try asking the question on the Spring forum as well. They surely know it better.
