...ANSWER
Answered 2021-May-24 at 11:50Assuming this is the SQL Server JDBC driver, try using a newer version (e.g. current latest is 9.2.1), and see if that resolves the problem.

I have a JSF web application that worked under Java 6, Glassfish 4.1, SQL Server 2012, Nebeans 8 but I am receiving an error under Java 8, Glassfish 5.1.0, SQL Server 2014, Netbeans 12. It varies some, but it is usually a handshake, socket, or class not found (focused on a servlet).
Hand shake error:
...ANSWER
Answered 2021-May-16 at 20:13It's not much of an answer, but when in doubt, then nuke everything and start again.
I deleted and removed the ODBC driver, SSMS, Netbeans, and Glassfish, and reinstalled each component. I made sure the firewall is open on TCP/UDP 1433-1434, and all the SQL Server services are running.
I made sure the ODBC driver was made available in the suggested Program Files directory. I made sure to enable SQL Server and Windows Authorization, the sa login is enabled, allow remote connections.
I copied the installed ODBC driver sqljdbc42.jar to make it available for projects. I minimized the number of jars each project was referencing, and included the Java 8 API and Java 8 Web API libraries.
I removed the sun folder from the grzzly jar in Glassfish.
I cleaned, built, and deployed each project before it began working in the problem project.
