Open source risk rarely shows up at install time. It shows up later—when versions age, patches lag, and security vulnerabilities surface. Lifecycle planning matters. bit.ly/49VyZbi #OpenSource #OSSSecurity #SoftwareLifecycle

GF 7 now supports @MicroProfileIO REST Client, with Config and JWT-Auth supported already. Admin Console is a bit more snappy. A new, Docker-friendly way to start server in foreground. Lot of fixes, improvements, and component upgrades. Enjoy!

By the way, Eclipse Transformer tool does it for you and much more. See how to use it, it’s just a simple command line command: omnifish.ee/2023/06/20/upgra…
When migrating your JSF pages to @JakartaEE Faces, don't forget to update your XML namespaces <html xmlns="w3.org/1999/xhtml" 𝘅𝗺𝗹𝗻𝘀:𝗵="𝗷𝗮𝗸𝗮𝗿𝘁𝗮.𝗳𝗮𝗰𝗲𝘀.𝗵𝘁𝗺𝗹" 𝘅𝗺𝗹𝗻𝘀:𝗳="𝗷𝗮𝗸𝗮𝗿𝘁𝗮.𝗳𝗮𝗰𝗲𝘀.𝗰𝗼𝗿𝗲">

Alternatively, you can also have detectable Faces artefacts in your application. Faces then inits and maps a Servlet automatically. @FacesConfig is probably the easiest now (since there is no more @ManagedBean, and the other annotations are rarer to use in an app)

AFAIK, the latest Faces version spec allows using the legacy namespaces that start with org as well as the new ones that start with jakarta. But doesn’t allow older variant of the namespaces that starts with com.sun
