Getting data from MSSQL to Jlink

Some old discussion - "JLink": https://community.ptc.com/t5/Customization/JLink/td-p/199246 

It seems to, I can't get the Microsoft driver to load.

I use this code:Connection connection = null;
String url = "jdbc:sqlserver://xxxxxx\\DTW:63825;databaseName=DataWarehouse;encrypt=false;trustServerCertificate=false;loginTimeout=30;";
Statement stmt = null;
ResultSet result = null;
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String databaseUserName = "xx";
String databasePassword = "xx";

try {
  // Class.forName(driver);
  connection = DriverManager.getConnection(url, databaseUserName, databasePassword);

} catch (SQLException ex) {
} finally {
  try {
    if (connection != null && !connection.isClosed()) {
      connection.close();
    }
  } catch (SQLException ex) {
  }
}

Here I got no suitable driver found.

If I also have Class.forName(driver); added I got no class found.

I have the sqldriver in my classpath.

Any ideas?
