When adding project to OpenLiberty Server , the following error occured.
The server does not support version 5.0 of the J2EE Web module specification.

By now , I'm not sure that was caused by Eclipse IDE , nor by OpenLiberty Tools.
Eclise community already had a ticket : https://bugs.eclipse.org/bugs/show_bug.cgi?id=579533

And also , have a question,
will https://github.com/OpenLiberty/open-liberty-tools be replaced by https://github.com/OpenLiberty/liberty-tools-eclipse in the future.

thanks~

Hi @RuiBaiXYZ,

I'm afraid there's no plans to support Jakarta EE 9.1 in Open Liberty Tools at this time. I believe Liberty Tools https://github.com/OpenLiberty/liberty-tools-eclipse does have some support, but check with them. I can confirm that there are no plans to replace Open Liberty Tools with Liberty Tools at this time.
