ApplicationInterface and ResourceAdapter with AE version 12.1

Discussion created by Joachim_Zientek_934 on Jan 10, 2018
with version 12.1 ResourceAdapter is no more supported for accessing UC4 ApplicationInterface.

In previous versions ResourceAdapter was necessary to use ApplicationInterface with Enterprise JavaBeans(EJB).
The manual said that due technical limitations the ApplicationInterface cannot directly be used by EJB.

Is technical limitation now solved ?
Has anyone experience with using UC4 ApplicationInterface in WebSphere without ResourceAdapter?
Can UC4 ApplicationInterface be used by EJB directly?

Thank you for support.
