Good Resources for Learning to Write Java codes and Designing Activities
I'm quite new to Pega. While I like the Pega's effort to eliminate coding and even discouraging the use of activities as much as possible, I'm still inclined to learn activities and even use them in applications when necessary.
I played around with activities on my own and learned a quite a bit. I'm comfortable with looping through data page list, skipping / jumping to steps, connecting to databases, creating, modifying, copying, and deleting data pages.
However, I want to take to the next level and learn some advanced features of activities and while at it, learn how to use custom Java codes (I consider myself to be a decent Java developer).
I tried to look for some resources on Google, but no luck so far.
Is there some good resources out there or any courses provided by Pegasystems on activities and Java coding in Pega?
