Hi @adam.labus,
Thank you for your swift response. We have been reviewing the documentation you provided, as well as other articles, including this one, regarding the Platform 7 upgrade (where you discussed it with @MarekTokarski)
We believe we should still be able to use javax imports. Given that our endpoints do not return a 404 status, we assume they are registered as REST v2. However, we are encountering a 405, not really sure what could be causing this.
