Type: New Feature
It is currently not possible to define JavaMail Sessions via standard annotations or XML. This is a potential usability issue, especially in cloud environments.
It may be very helpful to have portable annotations or XML for this, just like we now have for data sources and JMS resources.
Do let me know if anything needs to be explained further - I am happy to help.
Please note that these are purely my personal views and certainly not of Oracle's as a company.
