a few questions regarding to transaction and clustering:
1. if we use spring transaction management in SLSB, and rely on app server to perform clustering, will the spring tx break? or do we need to take any special care?
2. is it true to say that if we use spring transaction mgt in SLSB, we are using bean managed transaction?
3. (not so spring specific) could we make use of the app server's clustering without using EJB?
4. (a more general question) what are the recommended approaches for using Spring transaction in a clustered environment?
