Using logback 1.5.x works in javax namespace application

[mvestola]

Below pages quite clearly state that logback 1.5.x is for Jakarta EE (jakarta.* namespace) and 1.3.x is for Java EE (javax.* namespace):

• https://logback.qos.ch/dependencies.html
• https://logback.qos.ch/news.html
• https://logback.qos.ch/setup.html

However, I noticed that 1.5.x runs just fine with an application which is using javax namespace. This application uses embedded jetty jetty-ee8-webapp 12.0.16 (so javax with servlet api 4). Logback dependencies are logback-core and logback-classic with 1.5.16 version and logback-access-jetty12 with 2.0.6.

To my surprise, the server starts up just fine with these dependencies and logging works just as expected: both access logs and other logging works just fine. I have not seen any issues.

So just wondering what are the features which will not work with this setup when using logback 1.5.x in javax namespace? We use pretty basic stuff from logback, so basically just basic logging and access logging.

I would definitely want to keep using 1.5.x version, however, a bit concerned about that it is not really recommended in the docs, so wondering impacts of this one. I could not use latest 1.3.x release in this application since the jetty 12 (jetty-ee8-webapp) did not seem to work with older logback access dependency, so have to use the latest logback-access-jetty12 which requires then logback 1.5.x.

As long as you are not logging via a servlet or emailer, then it will work fine. You can easily see this by this search https://github.com/search?q=repo%3Aqos-ch%2Flogback%20%22import%20jakarta%22&type=code

OK. That sounds good. Just wondering that should the documentation be updated to mention somewhere that you can use 1.5.x with javax namespace. Since at the moment it is not that clear that 1.5.x works with javax but I guess many use 1.3.x even though 1.5.x could be used also in most cases.
