This driver does not support Java Runtime environment (JRE) version 1.8. Use the Sqljdbc4.jar class library, which supports JDBC 4.0.

Before, also encountered such a problem, let me tangled up long time. Finally the solution was finally tried out.

We downloaded sub-folders under the Sqljdbc4.0 folder in JDBC 4.0 CHS with two jar files, Sqljdbc.jar and Sqljdbc4.jar. We follow the online blog, when the configuration to establish the data connection, add is Sqljdbc.jar this jar file, so there will be such a problem. Instead, you should add Sqljdbc4.jar. That would not have been the case.
