Now that you have learned all the details about the transactions managed by the Enterprise JavaBeans (EJB) container in part 1th, you may be curious about the transactions managed by the EJB bean and how you can implement it in the Apache Geronimo application server. In this installment of the three-part series (part 2nd), you can get all the details. Brief introduction This series, which is divided into three parts, explores how Geronimo and OPENEJ
