J2EE / EE frameworks
EJB-heavy stacks taught a generation that XML config was architecture. Spring and lighter runtimes absorbed the survivors.
How J2EE / EE frameworks mutated
J2EE sold application servers as the product instead of the app. Teams drowned in deployment descriptors while PHP shops shipped features. It mutated into Spring Boot because the market punished ceremony, not Java itself.

- Lidl walks away from SAP Retail — Estimated €500M+ over seven years before abandonment
- Deutsche Bank absorbs Postbank into integration purgatory — Multi-year, multi-billion IT integration; branch and core systems lagged for a decade
- The ESB hub that became the outage — Hours of nationwide payment and branch downtime; remediation and audit costs in the tens of millions
- Enterprise blockchain pilots that never left the lab — Eight-figure innovation budgets; production traffic near zero
- Low-code to replace engineering — then hire engineers — Seven-figure platform licenses; shadow IT integration debt
