Hi Developers!  Let me share with you some exercises from a workshop about developing interoperability components in Java using **PEX** (*Production EXtension*). You will find slides and step by step exercises about: * Understanding simple PEX components coded in Java. * Making some changes on them. All built using containers, so you don't need to build a local Java environment. You can reach the repository here: https://openexchange.intersystems.com/package/workshop-pex
