I regularly receive questions about available options for learning Oracle SOA Suite. This material is probably worth a blog post.
The best option to learn about anything new is of course through an in-person class. Oracle University offers several learning paths for Oracle SOA Suite. The starting point for these classes was an internal training that our product management team put together to get Oracle employees ready for the 11g release. Our curriculum organization then took over, polished, formalized and fleshed out the course. It's quite amazing to see how things can take a life of their own and that literally thousands of people around the world have now gone through these classes!
There are 4 main learning paths identified:
These learning paths consist of various related classes (WebLogic, XML, etc.) and specific SOA classes:
Head to the Oracle University page for Oracle SOA and BPM for more information on these learning paths and available classes. Classes are available around the world as you can see on the course catalog and schedule (http://education.oracle.com > Course Schedule). Note that these classes are also available as online "Self-Study Courses" if you cannot travel for a reason or another and that Oracle University can also deliver on-premise classes (an interesting option when you want to train a whole team on the technology).
Another thing I am quite proud of is the number of books available today on Oracle SOA Suite. As of this writing there is a dozen of books directly related to Oracle SOA Suite. When it comes to books I have to admit that I am somehow biased since I co-authored one of them. With this disclaimer in place, if you ask me what are the books I would recommend to a developer looking at learning Oracle SOA Suite I would say:

There are other online assets that you can use to further your learning of Oracle SOA Suite. None of these can or try to replace a training or a book; you should look at them as source of complementary information on specific topics.
