I just start a new job using AppFuse with Spring, Struts,.... I am wondering if this book "ProSpring" has other related technologies besides Spring ? I feel there are many nice stuff are all combined together. Hopefully I don't have to read too many books to learn them.
Unfortunately no, Pro Spring has no coverage of AppFuse. You might want to check out Spring Live as well since I believe that covers AppFuse in some detail. I think it is fair to say though that Pro Spring covers the Spring framework itself in much greater detail than Spring Live.
Spring Live doesn't have anything on AppFuse b/c the readers wanted me to save it for a later chapter (and cover Spring-specifics first). I'll probably write a chapter on it later this summer or fall. The tutorials should be good enough for now - or you can subscribe to mailing list: firstname.lastname@example.org.
Looks like many technologies can be used together, but I cannot expect just by reading a book to learn them all. I believe sooner or later AppFuse will grow big enough, then it will deserve a whole book to cover it.
I found out the the job market for Spring is very good now. Invest on it is worthwhile.
