Not connected 🔌

[sebjulliand]

@Phil-Tolbert which OS version are you trying to connect to?

@julesyan @worksofliam @ThePrez do we know which minimum JTOpen version is required to run Mapepire? It seems in this case that it's an old one that doesn't implement a JDBC method (an assumption based on the fact that this error is a first here).

[Phil-Tolbert]

The client is on OS Version 7.4.

[sebjulliand]

Until I get an answer from IBM, I'd advise you go back to version 2.18.0 since it's production halting for you.

[Phil-Tolbert]

I reverted back to 2.18.0 and I am able to connect to the customer's IBM i now.

[Phil-Tolbert]

Although I cannot open source members.

[sebjulliand]

What's in the Code for IBM i output?

[Phil-Tolbert]

[Phil-Tolbert]

Not sure if that is what you are referring to.

[sebjulliand]

No. In VS Code's Output tab at the bottom, select Code for IBM i. Copy/paste it's content right after the error occurs.

[julesyan]

@sebjulliand Mapepire should work with JTOpen >=11.2

[Phil-Tolbert]

What is the status of this issue?

[sebjulliand]

What is the status of this issue?

@Phil-Tolbert can you try connecting using the latest version?

If it still fails, please send the output of the Code for i output, from the output tab. There will be more info if it still fails. Thanks.
