For a long time, we used to sell the 200+ pages jPOS Programmer's Guide for a fee as part of the program to support jPOS.org and you can still purchase it (see below), but we are working now in a new version of the documentation that covers the latest jPOS and we want it to be free.
So for every purchase of the existing guide, we spend time working in the new free one.
The new guide draft is available for free here and now.
You'll see that it just cover a few chapters, which are very useful to get you going.
If you want to expedite the development of the new guide, and you want access today to the old guide (even though it covers version 1.6 of the jPOS, users say it's a great must-have resource), or just want contribute back to the project, you can click the "Buy Now" button below to get it.
