Implementing XA transaction for Mule 4 SDK connector

Question

I try to implement XA transaction for Mule 4.3.0 custom connector. In Mule 3.X.X versions and up Mule 4.2.X versions they are supporting the class

org.mule.runtime.core.internal.transaction.ExternalXaTransaction

In 4.3.0 they are removing the above mentioned ExternalXaTransaction class.

How to implement XA transaction in Mule 4.3.0

Answer 1

You should not use a class from an internal package ever (example: org.mule.runtime.core.internal...). They are implementation classes not meant to be used by user code and are not guaranteed to remain stable between versions.

In a connector created with Mule 4 SDK you should follow the documented instructions for implementing transactions. XA transactions require to use the XATransactionalConnection instead of TransactionalConnection.
