Migrate Your Legacy J2EE to Angular frontend and Spring Boot backend.
I help enterprises modernize J2EE (JSF/EJB) systems incrementally, keeping your business logic intact while eliminating WebLogic licensing costs and JSF security risks.
Is Your Legacy J2EE System Holding You Back?
You're not alone. These are the challenges I hear every day:
WebLogic Licensing Costs Are Out of Control
Annual license fees exceeding $400K, with no path to reduce costs without a risky rewrite.
Nobody Wants to Touch Your Codebase
Modern Java developers avoid EJB 2.x projects. Hiring is impossible. Knowledge is locked in the heads of retiring developers.
Deployments Take Days Instead of Minutes
Monolithic deployments require coordinated downtime windows. Small changes take weeks to reach production.
You're Stuck on Java 8 with No Upgrade Path
Modern frameworks require Java 17+. Cloud-native deployment is impossible. Security patches are piling up.
The Strangler Fig Migration Pattern: Proven, Low-Risk Modernization
Instead of a dangerous "big bang" rewrite, I use an incremental migration strategy that keeps your business running:
Assess
Map your EJB dependencies, identify the leaf nodes with minimal coupling, and create a prioritized migration roadmap with quick wins.
Strangle
Wrap legacy EJBs with Spring Boot REST APIs. Route new traffic through Spring while old code continues running. Gradually move business logic.
Migrate
Shift traffic incrementally using feature flags. When a module hits 100% Spring Boot traffic, decommission the EJB. Zero downtime. Zero risk.
