Hi Chege, The user list is the better place for questions like this. Quick tip though, try creating a small sample using the recently released Johnzon 1.2.19. I've also found the error messages to be not helpful and spent a month auditing and reworking them all. Hopefully we can get that into a TomEE release soon.
Let me know if the issue is more obvious with the new messages -- that would make my day :) Of course, if it's still not obvious, let me know and I'll see what can be improved. -- David Blevins http://twitter.com/dblevins http://www.tomitribe.com > On Aug 23, 2022, at 6:59 AM, chege <ch...@programmer.net> wrote: > > Hi, > > I have a simple use case where I want convert json to pojo. > All values are quoted including booleans, longs and ints. > Jsonb specification says parse$Type e.g parseInt > or > parseBoolean shall be used.
