In order to help readers solve this problem, PHP editor Baicao has carefully compiled some practical suggestions and solutions to avoid compatibility issues between Java EE and Jakarta EE. Through the question and answer format of this article, I hope to provide readers with better guidance and help, making the process of using Java EE and Jakarta EE smoother.

Question content

After Oracle donated Java EE to the Eclipse Foundation, it was renamed Jakarta EE.

In this way, the javax namespace is changed to jakarta.

What should I pay attention to in order to avoid compatibility issues due to the change from Java EE to Jakarta EE?

Solution

Don’t mix java ee and jakarta ee dependencies

You cannot use java ee and jakarta ee at the same time. You must use one of these.
If the project uses java ee, there should not be any jakarta ee dependencies in the project.

Here are some examples of java ee/jakarta dependencies (in group.id:artifact-id notation):

Java EE dependency	Jakarta EE dependency
javax.servlet:javax.servlet-api	jakarta.servlet:jakarta.servlet-api
javax.persistence:javax.persistence-api	jakarta.persistence:jakarta.persistence-api
javax.xml.bind:jaxb-api	jakarta.xml.bind:jakarta.xml.bind-api
javax.validation:validation-api	jakarta.validation:jakarta.validation-api
javax.mail:javax.mail-api	jakarta.mail:jakarta.mail-api
