Java EE / J2EE
Also written as J2EE, Java EE, Jakarta EE, Servlets, JSP, EJB, Struts
The older enterprise Java platform (servlets, JSP pages, EJBs, frameworks like Struts) that Spring and Spring Boot have largely replaced. Now maintained as Jakarta EE.

The mainframe-era office block that still houses half the bank, next door to the new glass tower (Spring Boot).
