In Denodo Platform 7.0, the Denodo JDBC driver is compiled with Java 8. Hence, the applications that use the JDBC driver with earlier versions of Java will have to update to Java version 8 or higher in order to load this driver. You can download the JDBC driver for the Denodo server [here](https://community.denodo.com/drivers/jdbc/32).
For more information, you could refer to the below documents,
* [Java versions supported by the Denodo Platform](https://community.denodo.com/kb/view/document/Java%20versions%20supported%20by%20the%20Denodo%20Platform?category=Installation+%26+Updates).
* [Access Through JDBC](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/access_through_jdbc/access_through_jdbc#access-through-jdbc).
