As I understand varous posts, there are major architecture changes from 2.4 to RH. I thought it might be clear from docs (flashline pdf) but unfortunately that only covers 2.4. So, is there any other docs available for RH internals???
As a sidenote, the CMP2.0 docs should be described a little bit more on flashline. (as it proves to be a donation to JBoss group instead of being of much value to the user).
