Oracle JDK 17 and future JDK releases are provided under a free-to-use license until a full year after the next LTS release. Since the previous JDK 11 LTS released three years ago, over 70 JEPs have been implemented. Java 17 is the latest long-term support (LTS) release under Java’s six-month release cadence and is the result of extensive collaboration between Oracle engineers and other members of the worldwide Java developer community via the OpenJDK Community and the Java Community Process (JCP). Java 17 delivers thousands of performance, stability, and security updates, as well as 14 JEPs (JDK Enhancement Proposals) that further improve the Java language and platform to help developers be more productive.

Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. The new license permits certain uses, such as personal use and development use, at no cost - but other uses authorized under prior Oracle JDK licenses may no longer be available. The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses. It is capable of creating and compiling programs. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). Make sure that the class name and file name are the same.The JDK is the Java Development Kit, the full-featured SDK for Java.
