First, check whether the jar file that you’ve used contained the namespace of the class, you can do so by using 7zip and open the archive and see if you can see the folder structure down towards the subfolder containing the class file.
Then you can also take a look at the IS about page. Take a look whether the jar file is loaded as part of the classpath. If yes, then there shouldn’t be a reason why this is not working.
Over the year, I’ve supported and reproduced so many cases, and the conclusion usually ended up with either the path is not correct, the jar file is not right, or the jar file doesn’t contain the class file for which the driver is using.
You’ve to do further troubleshooting on this.
Another thing that SAG R&D would perhaps ask you to do, create a java jdbc program in eclipse. Try to use the same jar file and see if the java file works or not. That will help you to narrow down whether it’s jar file issue or otherwise.
