My second and last stop on the LAOUC Community Tour 2025 was São Paulo. This event, GUOB Tech Day 2025 was organised by the Brazilian Oracle User Group (GUOB) and about 300 attendees showed up.
I presented a talk titled The Past, Present, and Future of Enterprise Java as one of the last slots of the day for a small but very enthusiastic group. In this talk, I go back to the early days of J2EE and take us through the history up until modern day Jakarta EE. The talk also include demos for Jakarta Data and the virtual threads support in Jakarta EE 11.
The visit to São Paulo was a fairly short one this time, but I got to experience the Brazilian hospitality and great food. Tomorrow, I may even squeeze in a run in the park before my flight home.
