💡 Enhancement Ideas

Here are some ideas for more enterprise-related patterns to add to the enterprise category:

1. EJB Timer vs Jakarta Scheduler — Show the migration from heavyweight EJB @Schedule/TimerService timers to Jakarta Concurrency's ManagedScheduledExecutorService, highlighting reduced boilerplate and better testability.

2. JNDI Lookup vs CDI Injection — Compare the old InitialContext.lookup() JNDI pattern with modern CDI injection, demonstrating how container-managed dependencies eliminate fragile string-based resource lookups.

3. Manual JPA Transaction vs Declarative Transactional — Contrast the verbose em.getTransaction().begin() / commit() / rollback() boilerplate with the declarative @Transactional annotation, showing how AOP-based transactions reduce error-prone manual lifecycle management.

4. SOAP Web Services vs Jakarta REST — Illustrate the shift from heavyweight SOAP endpoints (with WSDL overhead) to clean Jakarta REST resources using @Path, @GET, and @POST, reflecting how modern microservices favour JSON over XML/SOAP.

5. Message-Driven Bean vs Reactive Messaging — Show how a traditional EJB consuming from a JMS queue compares to a MicroProfile Reactive Messaging method, emphasising the simpler programming model and better cloud-native fit.

6. JSF Managed Beans vs CDI Named Beans — Replace @ManagedBean (deprecated in Jakarta EE 10) with @Named + @RequestScoped CDI beans, showing how the unified CDI model eliminates the old JSF-specific lifecycle.

7. Singleton EJB vs CDI Application-Scoped Bean — Contrast a Singleton EJB (with container-managed concurrency and lock annotations) against a plain @ApplicationScoped CDI bean, helping developers choose the right tool for shared state.

8. JDBC ResultSet Mapping vs JPA Criteria API — Move from manual ResultSet column-by-column mapping to type-safe JPA Criteria queries, demonstrating how the Criteria API eliminates raw SQL strings and runtime field-mapping errors.
