In order to check the Tomcat version on a Linux system, the following steps can be taken: 1. Open the terminal window. 2. Change to the Tomcat directory. Depending on your system, this can either be /usr/share/tomcat or /opt/tomcat.3. Run the command ‘bin/catalina.sh version’ to display the Tomcat version. 4. Run the command ‘bin/catalina.sh -v’ to display additional information about the version, such as the build date and time.It is also possible to check the version number from the Tomcat admin page. To do so, start the Tomcat server with the ‘bin/catalina. sh start’ command, and then navigate to on any browser.The page will display the Tomcat version information.What is the latest Tomcat version?The latest version of Tomcat is version 9.0.37, released on September 30th, 2020. This version comes with numerous bug fixes and other improvements. Some of the highlights of this version include: • Improved startup performance and reduced memory usage• Improved compatibility with Java EE 8 and Jakarta EE 8• Apache Tomcat security hardening• Simplified tag library development with the Unified EL• Improved support for WebSocket• Support for Java Servlet 4.0• Improved TLS/SSL protected communication• Improved HTTP/2 support• Improvements to Comet support• Improved support for the Java Management Extensions (JMX)Tomcat 9.0.37 is available for download from the Apache website, and is the recommended version for all users looking to get the most out of their Tomcat installation.Is Apache and Tomcat the same?No, Apache and Tomcat are not the same. Apache is an open-source web server that is used to serve web content over the internet, while Tomcat is an open-source Java servlet container and web server. Apache is used for static content, such as HTML pages and images, while Tomcat is used for dynamic content, such as Java and JSP pages.Apache is generally installed and used in combination with Tomcat, as Tomcat can be used to handle the dynamic content while Apache serves the static content. Together, they provide a complete web server solution.Is Tomcat a HTTP server?No, Tomcat is not a HTTP server. It is an application server or servlet container. It is designed to run JavaServlet and JavaServer Pages (JSP) based applications. Apache Tomcat is developed and maintained by an open source community and built on open-source technologies.The server handles HTTP requests by employing a own Java based web server called Coyote. It interprets servlets and JSPs, generates replies to HTTP requests, parses HTML templates and serves static resources.Is Tomcat a web or application server?Yes, Tomcat is both a web and application server. It is most commonly associated with the Java servlet container that enables the deployment and running of Java applications. Tomcat is a web server that also provides a Java Servlet container and acts as a web container, which allows web applications written in Java to run within the server.It supports various web technologies such as JSPs (JavaServer Pages), Java Servlets, HTML, and CSS. Therefore, it can be used to deploy web applications written in Java, HTML, CSS, and JS. Additionally, Tomcat can be. What Is Apache Tomcat 8?

Used with the Java EE application platform, allowing developers to use the entire Java EE stack, including Enterprise JavaBeans, Connectors, Remote Method Invocation, and Java Message Service.Therefore, it can be used for both web and application server purposes.Is Tomcat part of Apache?Yes, Tomcat is part of the Apache Software Foundation (ASF). Apache Tomcat is an open-source software implementation of the Java Servlet, JavaServer Pages (JSP), and Java Expression Language (EL) technologies.It is developed under the Apache License, a free and open-source software (FOSS) license, and is commonly used to provide a platform for Java-based web applications. Tomcat is used by many organizations for both their large-scale web applications and smaller ones.It can be deployed as a stand-alone server or as part of the Apache HTTP Server, with which it works closely. Tomcat is also designed to be highly modifiable, allowing for users to make changes and customize their Tomcat server instance.How does Apache work with Tomcat?Apache and Tomcat work together to support dynamic, data-driven web applications. Apache is an open source web server that specializes in serving static web content such as HTML, CSS, JavaScript, and images.Tomcat is a Java servlet container for running Java servlets and Java Server Pages (JSPs). The integration of these two technologies provides a powerful, yet secure, platform for running web applications.At the core of the integration between Apache and Tomcat is the Apache Portable Runtime (APR). This library allows Apache and Tomcat to interact with each other as they share information and resources.Specifically, the APR library allows Apache to pass on requests regarding Java servlets and JSPs to Tomcat. Once Tomcat receives the request, it invokes the appropriate servlet or JSP to process the request and respond to the client with the generated Java content.The integration of Apache and Tomcat allows web applications to be both reliable and secure. Web applications are securely housed within the Java servlet container, while Apache provides the web server resources and scalability necessary to efficiently serve content to end users.What version of Java does Tomcat 9 use?Tomcat 9 uses Java 8 or later. Tomcat versions 9.0.41 and later use OpenJDK 8, while earlier versions use OpenJDK 7. OpenJDK is an open-source implementation of Java Development Kit. OpenJDK 8 is the latest version of OpenJDK, released on March 18th, 2020.As of version 9.0.41, Tomcat requires the Java Runtime Environment (JRE) version 1.8.0_212 or later. It is important to use a compatible JRE version for Tomcat 9 to ensure that it runs correctly. Additionally, it is recommended to use the Java Development Kit (JDK) to manage Java libraries and configurations.If you are using a compatible version of the JDK and JRE, the two can be used interchangeably.Does Tomcat require JDK or JRE?Yes, Tomcat requires either JDK or JRE (Java Runtime Environment) to be installed. Tomcat is a web server application written in the Java programming language. The Java environment is required to run the server and the web applications deployed on it.Therefore, you must have either JDK (Java Development Kit)

OpenBoxes currently depends on Java 8. Therefore, we need to install a version of Tomcat that has been compiled with Java 8. Choose Installation Method¶Option 1: Install from APT repository (easiest)¶The simplest way to install Tomcat 9 is to install the tomcat9 package from the APT repository. This is not the recommended approach, but should be sufficient for most users. ImportantThe Tomcat 9 package available from the APT repository was compiled with Java 8, but has dependencies that were compiled with a later version of Java. This causes incompatibility issues for certain features, so we only recommend this approach if you(a) are a novice with Ubuntu and Tomcat AND(b) don't plan to use more advanced features like the Tomcat Manager or CI/CD pipelines. TL;DR: If you don't understand what you just read, then Option 1 is probably an ok option for you.Option 2: Install Manually (recommended)¶Create user¶The first step in the process is to create a new Tomcat user that will execute all Tomcat processes.sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcatDownload latest version¶Go to the Tomcat Versions page, find the table named Currently Supported Versions and find the Latest Released Version for 9.0.x. At the time this document was published, the latest release was 9.0.98, so we'll use wget todownload the binary version of the Tomcat server using the following URL.wget -c contents¶Once the tar.gz file has been downloaded, we need to extract the contents onto the file system. This can be done using the following command. sudo tar xf apache-tomcat-9.0.98.tar.gz -C /optIn addition, we need to change ownership of the Tomcat directory and make all scripts executable. sudo chmod +x /opt/apache-tomcat-9.0.98/bin/*.shCreate symlink¶In order to update Tomcat more easily in the future we recommend creating a symlink sudo ln -s /opt/apache-tomcat-9.0.98/ /opt/tomcatConfigure Tomcat Service¶Determine Java Runtime path¶Copy and paste the output. It will be used to replace in tomcat.service.readlink -f /etc/alternatives/javaFor example, on the server we're using to write these instructions, the path looks like this /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/javaCopy the path up to /bin/java.
