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

Very interesting read

Doron B.@Doron__B

doron.hashnode.dev/how-humanity-g… My first ever article! Because everyone should write extensively somewhere, even if it's globally embarrassing. It's very long, but give it a chance, as you might learn something... or fall asleep. #Programming #History #Math

@iamdvr @Java_EE @JakartaEE That's a unique problem. I'm afraid I don't have much experience with that particular situation. Perhaps instead of bytecode manipulation, run a script at build time to change the imports, then use maven profiles to change the dependencies.

Desu Venkateswara Rao@iamdvr·8 Tem

@ensode @Java_EE @JakartaEE We have a need for generating two artifacts one for javax and other for Jakarta... Need byte code replace after artifact generation.. any help appreciated

English

David R. Heffelfinger@ensode·28 Haz

Been migrating some @Java_EE projects to @JakartaEE recently. For the most part, all it takes is a global search and replace: Replace all occurrences of "import javax" with "import jakarta" And stuff "just works".

@seinecle @JakartaEE @netbeans @OmniFaces @ASFMavenProject @gradle pom looks good. Not sure if it will make a difference, but it may be worth a shot to upgrade to @NetBeans 18 final. That's what I'm using, and it recognizes the new namespaces just fine. netbeans.apache.org

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">

@seinecle @JakartaEE @netbeans @OmniFaces Works for me. I'm on @NetBeans 18, try upgrading if you are on an earlier version. Also make sure your @ASFMavenProject / @gradle dependencies are for Jakarta EE <groupId>jakarta.platform</groupId> <artifactId>jakarta.jakartaee-web-api</artifactId>

English

Clement Levallois / [email protected]@seinecle·6 Tem

@ensode @JakartaEE just did the change and @netbeans gives me red alerts everywhere! (the app compiles though). Same happens with @OmniFaces by the way. Example in screenshot. Super annoying bc now I can't spot actual errors.

English

David R. Heffelfinger@ensode·6 Tem

When migrating to @JakartaEE , don't forget to update your JPA propertis in persistence.xml <properties> <property name="𝗷𝗮𝗸𝗮𝗿𝘁𝗮.persistence.schema-generation.database.action" value="create"/> </properties>
