What are container-managed transactions?
Rating:
Container-managed transactions are those in which the container is responsible for managing the transaction boundaries. Such transactions are also known as declarative transactions. To use a container-managed transaction, the transaction type must be specified in the deployment descriptor. Container-managed transactions simplify development because the enterprise bean code does not explicitly mark the transaction's boundaries. When deploying a bean, the developer specifies the bean's methods that are associated with transactions by setting the transaction attributes in the deployment descriptor file.
