Subject Re: MariaDB/JPA Transaction rollback not working
Date Mon, 21 May 2018 18:08:34 GMT
I ended up using Aries JPA 2.7.0 with the JpaTemplate approach.  
I can’t spend more time on this.

I suppose the next Karaf release will support OSGi 7.0, then I can try again.


Now with Aries JpaTemplate, transactions are correctly rolled back on exception, but I can’t use the TransactionType.Supports option as it throws exception:

java.lang.IllegalStateException: Only transation propagation type REQUIRED is supported.

Any idea why?

Best regards,
Alex soto

At a guess you are picking up a 1.3 requirement because you have the 1.3 annotations ahead of the 1.4 annotations on your classpath, but it could be triggered by other things too. On the other hand this isn’t actually a problem as the requirement is still satisfied by DS 1.4 and both versions will work for you at runtime.

You may need help from a more Karaf focussed person to confirm this.

The comments also indicate a misunderstanding of the purpose of the non-jta-datasource, which absolutely is used with JTA EntityManagers (for things like sequence allocation and out of band optimisations). You really do need to have both and they do need to behave differently.

This usually happens by configuring a (otherwise invisible) DataSource wrapper There is nothing forcing you to make this happen (or checking that it does) hence your transactions would be broken. This is one of the several reasons I try to direct people to Transaction Control where the model actively pushes you toward transactions that actually work, rather than hiding all the magic behind an annotation.
