Renovix Java EE migrates EJB 2.x and 3.x, JSP, Struts, JBoss Seam, and Java EE 5–7 applications to Spring Boot 3 and Jakarta EE 10. Transactional semantics and security contexts are preserved.
Built for the long tail of frameworks that grew up around early Java EE — and the customizations layered on top.
Session, entity, and message-driven beans, including container-managed persistence.
Page-driven UI lifted to React or Blazor with type-safe API contracts.
JNDI bindings, datasources, and JMS topology mapped to cloud-native equivalents.
Older Spring stacks lifted to Spring Boot 3, Spring Security 6, and Spring Data.
IBM MQ, ActiveMQ, and TIBCO EMS mapped to Kafka, SQS, or Spring Cloud Stream.
Build files modernized alongside the code. CI pipelines generated.
Renovix doesn't wrap legacy patterns in modern syntax. It re-expresses business logic the way a senior Spring engineer would write it today — with constructor injection, immutable DTOs, and declarative transactions.
// Legacy: EJB 2.1 stateless bean public class PaymentBean implements SessionBean { private SessionContext ctx; public void charge(Long id, BigDecimal amt) { try { DataSource ds = (DataSource) new InitialContext().lookup("jdbc/PayDS"); // ... 80 lines of JDBC ... } catch (NamingException e) { ctx.setRollbackOnly(); } } } // Renovix → Spring Boot 3 @Service class PaymentService( private val repo: PaymentRepository, ) { @Transactional fun charge(id: Long, amt: BigDecimal) = repo.save(Payment(id, amt)) }
// Transaction semantics preserved { "original": "CMT REQUIRES_NEW", "target": "@Transactional(propagation=REQUIRES_NEW)", "verified_isolation": "READ_COMMITTED", "replay_runs": 412009, "deadlock_parity": "identical" }
The verifier doesn't just compare outputs — it observes transaction boundaries, isolation behavior, and exception flow under load. The translated app behaves the same under contention as the original, or it doesn't ship.
EAR, WAR, and library inventory; framework fingerprinting; SME interviews.
Bounded contexts proposed; data ownership and service boundaries reviewed.
Module-by-module generation with tests, build, and CI pipelines.
Load-replay against production traffic with transactional invariant checks.
Per-service traffic shift with instant rollback and burn-in window.
Every change request mapped to a ticket, every deploy linked to evidence.
Cardholder data flow maintained or de-scoped — your call, documented either way.
PHI handling preserved with BAA-friendly architecture in the target stack.
