Hello Mark Hansen,

First of all i would like to congratulate you for promoting "SOA using web services", and giving us a chance to win a copy of it.

I wanted to clarify some of my doubts related to SOA:

1) how is web services related to SOA, and since web services is a very old concept used by the indusdry while SOA is a new concept, so how do you think web services will be able to solve out SOA purposes.

Dear Seema,
It is pleasure to have a new book for SCJP as it will beneficial for having more materials and options for preparing. I would like to know what is the uniqueness and new features you have embedded in your book.

I would prefer to read this book as I know there are many features which we can't discover without a book.
but if i set the scope to request will not the previous data get lost,
as i will gather all the data only in one Action class , and for each page i
have to submit different action in the JSP page/form.

or shall i use 4 different ActionForm beans one for each JSP pages
and what will be the scope of the ActionForm bean in action mappings.
