Camel in Action Book
I am trying to learn Camel from the book 'Camel in Action'. The current
edition of the book uses Camel 2.5 while Camel is now at version 2.17. I
need help with these questions:
1/ Is there a big difference between the 2 versions?
2/ If I complete the book, what kind of other resources/subjects should I
look at in order to update myself to the newer versions of Camel?
Note that I don't have time to wait for the new edition of the book,
apparently scheduled to be released in March 2017.
Many thanks for helping!!

There are significant differences between 2.5 and 2.17. The principles are
the same and EIPs are as well so the important concepts will be there for
you. But details will vary some.

Oh, I should add that my favourite addition to Camel since then is the REST
DSL which allows you to write a REST API directly as a Camel route instead
of relying on CXF proxy classes. It allows you to use one of several
different libraries as your backend, too. See here for more info:
https://camel.apache.org/rest-dsl.html

Thanks guys for the information!
I’ve just had a quick look on the REST DSL page. Even though I am a novice, I can guess that this would be a great feature for the project we’re trying to initiate as we’re trying mostly to integrate RESTful web services.

It makes sense. I sort of view successive generations of Camel as
representing a superset. I'm not sure if Camel is using semantic versioning
(I assume so) in which case everything from 2.1 up to 2.7 should be
backwardly compatible.

Claus always mentions it in the release vote threads. It's a good code
sample that's easy to test against without having to test out some overly
complicated enterprise app to find every nook and cranny.

Matt,
That's interesting. I didn't know the code was tested against each new
release. Makes sense though. Most of what I've seen over the years has
been (a) added features, (b) bug fixes, and (c) performance enhancements.
And of course the ever growing library of components.

All the code samples from CiA are tested against each release, so they all
still work. There's a lot of new components since 2.5, but the basic DSL
remains the same.

Hear, hear! My one hope for the new book is that the emphasis is on using
POJOs for most message processing in lieu of using Processors. I've found
that once my clients understand how Camel can select a method for
invocation on a bean for a route and how easy that makes unit testing for
constituent pieces a lightbulb goes on and they feel like Plain Ol' Java
Programmers once again. An almost audible sigh of relief goes up. And not
using the Processors means I also see less of the tendency to use Camel as
something to read a file or endpoint in and then write a humongous
application with I/O inside a processor and let Camel do the heavy lifting
using the EIPs and components.
I'd save the intricate details of Processors for a more advanced topic in
the later chapters.

Hello,
I started learning Camel from scratch about two years ago and read "Camel as
action" at the beginning. I can confirm that "Camel in Action" offers still
a very good point to start. I knew nothing about Camel or EIPs in general
and just bought the book to see if Camel could provide some nice features
for the application I was going to build (and yes, it could indeed :)).
The book has a very clear didactic & straight-forward approach. Most of the
described topics stayed the same, more or less - if you develop a Camel
application, you may want to use the Camel website as your main reference,
because you often need very special endpoints/properties/features that
aren't documented in the book or where replaced by more flexible ones. But
to understand the basic idea behind camel, to understand what is good
practice (and what isn't), the book's perfect.

Hi
As others have said in this thread, then the source code for the Camel
in Action 1st edition has been updated to latest Camel releases up
till 2.15.6.
https://github.com/camelinaction/camelinaction
As we are working on the 2nd edition we decided to stop maintaining
the 1st ed source code after 5.5 years since the book was published.
Camel 2.x is the same basic principles, and what you learn in 1st
edition is good practice today.
So surely go ahead and read the 1st ed book.
If you buy the 2nd ed book from Manning you get the 1st ed for free (ebook).
