![]() With the additional features and options found in Tomcat 10, there is naturally some variant overhead that may or may not impact performance, and it may not be particularly imperative to upgrade to the latest and greatest right now. Or if your infrastructure is somewhat fragile, it might make sense to use the years left in the life cycle of Tomcat 8 to plan your migration out in detail as well as prepare for the worst-case scenarios. If you are stuck using JDK 7 now, the requirement of Java 8 or later would prevent you from upgrading to Tomcat 9. When deciding whether to upgrade your Tomcat deployment, there are several factors to consider based on your particular circumstances and environment. The built in SunJCE includes support for various SSL/TLS versions. Because of Java’s capabilities through JCE/JCA, Java can provide cryptographic functions itself using JSSE. This web server negotiates authentication and then passes or proxies requests back to Tomcat. When used primarily as a Servlet/JSP container behind a web server such as Apache HTTPd, it is typically necessary to configure the primary web server to handle TLS/SSL. An SSL/TLS certificate is required for this to work as a prerequisite, and the following line of code will enable HTTP/2 in your Tomcat SSL configuration: Ī more complete example might look like the following code block: Īs mentioned previously, the biggest advantage of using Tomcat with TLS/SSL is that Tomcat can be run as a standalone server, reducing the amount of infrastructure needed in your environment. This version is significantly faster than HTTP/1.1, allowing you to serve content directly to a web browser and bypass the need for an actual web server entirely.
