Differences Between Javax and Jakarta

• Javax: APIs and packages with the javax prefix are part of Java EE (Java Enterprise Edition), originally managed by Sun Microsystems and later by Oracle.
• Jakarta: It is the successor to Java EE under the administration of the Eclipse Foundation. With the transfer of Java EE to Eclipse, the name changed to Jakarta EE.

• Javax: Reflects the name of the original Java EE specification. All key packages, such as javax.servlet, javax.persistence, and javax.ejb, are grouped under the Javax name.
• Jakarta: Under Jakarta EE, packages and specifications have been renamed, replacing javax with jakarta. For example, javax.servlet is now jakarta.servlet.

• Javax: Applications developed using Javax are typically compatible with Java EE application servers. Older versions of application servers mainly support javax.
• Jakarta: With the renaming to jakarta, there was a break in code compatibility, as applications developed for Jakarta EE need to be adjusted to the new package names.

• Javax: Under Oracle, Javax evolved slowly with major updates but had a more conservative release cycle.
• Jakarta: Since being managed by Eclipse, Jakarta EE has adopted a more agile release cycle, incorporating new features more quickly, with an open community driving its development.

• Javax: With the transition to Jakarta EE, javax is not expected to receive significant updates in the future.
• Jakarta: It serves as the foundation for future Java enterprise platform specifications, focusing on modernization, cloud integration, and microservices development.
