Jar file download failed : NOT FOUND

[brianm]

Greetings.

I'm attempting to perform some operations against a MySQL 8.0.33 server. I created a SnapLogic MySQL database  account, and uploaded mysql-connector-j-8.0.33.jar to the JDBC driver property of the account configuration popup. Pressing the validate button shows a positive result. I can also confirm a valid connection from the MySQL side.

However, when I use this connection in a MySQL Execute snap, I receive an error: "com.snaplogic.api.ExecutionException: Jar file download failed : NOT FOUND."

There are no network obstructions. The username/password is absolutely correct and validated by multiple means.

Any ideas?

@brianmDid you browse to the driver jar location from the snap property, or did you copy and pasted the file name directly into the account configurations?

I browsed and uploaded from the snap property a few times. I also tried copy/paste. Same result either way.

Same issue here, with some interesting timeline:

• We want to connect to our MariaDB Maxscale database load balancer, using cyphered connection. This seems to require the Connector J, so we upload it, select it as JDBC JAR, provide the credentials, Validate the connection: all goes well.
• But then, pipeline fails, with following indication: "failure=Jar file download failed : NOT FOUND".

Now, the weird part:

• Coming back to Account, I remove the custom JAR line; now *validation still works* (when it didn't previously without the custome JAR file.)
• And the pipeline do not fail anymore!

I will open a support ticket on this; @brianm do you experience the same behavior?

For information, I just created support ticket #64963.
