Openjdk version “12.0.2” 2019–07–16 OpenJDK Runtime Environment (build 12.0.2+10) OpenJDK 64-Bit Server VM (build 12.0.2+10, mixed mode, sharing) Installing JDK on Mac OS using Homebrew On the other hand, if JDK is installed, you will be promoted a message which will look similar to the following: No Java runtime present, requesting install. If the JDK is not installed, then you will be prompted with the following message To check if java installed, open up the terminal and run the following command: java -version In order to install Apache Tomcat on MacOS, we firstly need to install Java Development Kit(JDK). Overall, due to its features and large pool of resources, Apache Tomcat is a viable solution for both small users and large companies that use Java applets on their websites.Installing Apache Tomcat on MacOS Mojave using Homebrew On the other hand, the server is developed by a large community that provides support and feedback for the developers. First of all, it is a non-commercial solution that can be implemented in any project with minimal resources. While there are other alternatives to Tomcat, there are some advantages that make it a reliable solution. It is also responsible of sending the feedback back to the client after it has been processed. The communication between the server and the clients are handled by the HTTP connector that listens to the TCP connections and sends the requests to the JSP Engine. Servlet container, HTTP connector and JSP engine The servlet container, also known as Catalina, directly interacts with the Java applications and ensures that the access rights of the user are correctly maintained during the session. The main components of the server are the servlet container, the HTTP connector and the JSP engine that runs the dynamic content. This greatly improves the reliability of the application and the response time for the end user. If you are creating a website that also includes Java code and applets, this application can help the web server run them instead of running in the user’s Internet browser. Java-based web server for running web apps While the HTTP server delivers the webpages to the end user, Tomcat is the tool that provides servlet support in order to add dynamic content to the server. In web development, Apache HTTP server is used in order to provide the backbone of multiple websites by processing the requests of the clients. These applications can be run in the interface of an Internet browser such as Firefox, Chrome or Internet Explorer. Apache Tomcat is a web server developed in Java that aims to provide you with a pure Java environment for running web applications.
