What exactly is difference in BeanMangedPersistance and you may ContainerMangedPersistance? Updated CMP entity beans give top results than BMP organization kidney beans. Swinging with the CMP based means provides database versatility since it doesn’t consist of one database shop APIs in it. As the container work database functions on the behalf of the CMP entity bean, he could be more complicated in order to debug. BMP beans also offers more control and you will independency you to definitely CMP beans. Diff step one) In the BMP you’ll maintain all commitment and you can you establish the new SQL password into the bean whereas inside the CMP the box covers it Diff dos) The fresh new BMP isn’t smartphone across most of the DB’s.while the new CMP is actually
