Hello Asif
I�m working with was and you can find lot�s of excellent
books and training in IBM�s site, just here
http://www.redbooks.ibm.com just make a search with 'websphere'
For example 'Websphere Application Server 3.5 Handbook' is
excellent.
I also found one of the official courses (was developer
workshop) offered as a free online course in was developer
domain, library section, at ibm�s. Well, lot of nice stuff
there
Good luck
