Hi Mark,

I have struggling for many years JBuilder DataExpress (DX) library together with JayBird. The following exceptions messages are sporadically thrown:

no transaction for request
invalid transaction handle
This connection is closed and cannot be used now
You cannot getAutomcommit on an unassociated closed connection

I have been playing around with DX Database object properties.

Now thought to try the Jaybird 3 Beta with a lot of optimism! Unfortunately after some calls I get this exception all the time:
