Tomcat 9 Java 8

admin

Mar 30, 2021 Any installed Java 8 or later JRE (32-bit or 64-bit) may be used. Tray icon: When Tomcat is run as a service, there will not be any tray icon present when Tomcat is running. Note that when choosing to run Tomcat at the end of installation, the tray icon will be used even if Tomcat was installed as a service. Since Tomcat 8.0 has reached end of life, I want to upgrade my application directly to Tomcat 9. When I deploy my Java based App from local to my server, I have a script which overrides the server. As you can see, I have jdk-1.8 installed and bound to the project build path. I have spent hours trying to figure out why Eclipse keeps saying Java 1.8 is not supported by Tomcat 9. If you look in at the project facets runtimes, you'll see that the server shows jre-1.7 even though I have set the path to the jre-1.8.

Apache Tomcat 9.x is the current focus of development. It builds on Tomcat 8.0.x and 8.5.x and implements the Servlet 4.0, JSP 2.3, EL 3.0, WebSocket 1.1 and JASPIC 1.1 specifications (the versions required by Java EE 8 platform). In addition to this, it includes the following significant improvements. Jan 15, 2020 Installing Java Tomcat 9 requires Java SE 8 or later. We will install OpenJDK 11, the open-source implementation of the Java Platform. Run the following command as root or user with sudo privileges to install Java.
