How Renovio modernizes Legacy Java (Struts, JSP, J2EE)

Java has a uniquely strong tool — OpenRewrite — that mechanically handles 60–80% of upgrades. Renovio combines OpenRewrite for mechanical changes with Claude Code for business logic, dramatically cutting time and risk.

Typical signals you are in this bucket

  • JDK 1.6/1.8
  • Struts 1.x, JSF 1.x
  • Spring 2.x / 3.x, Hibernate 3
  • Maven 2 or Ant

Recommended target stack

Java 21 + Spring Boot 3 + PostgreSQL.
