Connecting to Athena using JDBC driver from a Spring Java application

0

Hello,

I am trying to connect to Athena via latest (2.16) JDBC driver jar from a Java Spring web application. The application also connects to S3 to upload files there. I am seeing this exception when bean for s3 client is being instantiated on addition of the Athena JDBC jar.

I tried upgrading aws-java-sdk-core to 1.11.793 and also latest 1.11.998 as suggested in this post, but it is not helping

Hi info2anu,

Based on the error it looks like you are missing a class your code depends on. I'd review the API and class doc carefully for build time requirements.
