SpringBoot Spring boot 3.3.3 still uses javax

I'm usingspring boot 3.3.3, i was under the impression that spring3+ migrated to jakarta, but seems to have missed some place as i can see in

[org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]

it still uses

import javax.sql.DataSource;

due to which i keep getting the below errror

Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlElement

SpringBoot Spring boot 3.3.3 still uses javax

Comment From: tobias-lippert

This is not a problem on the Spring Boot side, I think. Some packages are not migrated from the javax to the jakarta namespace. See https://github.com/jakartaee/platform/blob/main/namespace/unaffected-packages.adoc and javax.sql is one of them. The ClassNotFoundException you've posted refers to javax.xml.bind. This namespace has indeed been migrated to jakarta. So I assume this is a dependency problem on your classpath or an issue in your code. Note that I'm not part of the Spring team, so let's see what they think.

Thanks, @tobias-lippert. That’s exactly right.

hi @wilkinsona and @tobias-lippert , i have not posted the entire stacktrace, but it's due to the given file itself and not by any jar if my classpath, here is the entire stack trace for refrence

It looks like your application is using this Jackson module https://github.com/FasterXML/jackson-modules-base/tree/2.18/jaxb which in turn requires this class. Maybe use the Jakarta variant for this module instead? For further questions, please use StackOverflow
