A New Problem Comes Up.

when using spring transactional annotation, there exists a very important problem that is ignored easily.

that is:

after configuring the applicationContext.xml, and add an annotation "@transactional" in Service, a problem must be taken attention to: the ".jar" file that conflicts, which is named ams-2.2.3.jar..

doing this, the world goes around smoothly again...lol
