Where can i find the documentation for 2.5.x, i want to configure JMS using JBoss version 2.4.1 and documentation for the same seems to be available in the documentation for 2.5.x.
What do you mean?
There is no longer any 2.5.x. There is the stable release path from 2.4.x where x is three by now.
Is is documented in the JBoss JMS chapter, where 2.4.1 basically marks the latets features.
The JMS chapter no longer follows and documents the development branch. When 3.0 goes into beta release, the documentation will be updated to cover 3.0
