Apache tomcat server

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)

Database [Q] Quit - Do not proceed. No changes Choose [A]: AORDS installation is pretty straight forward. If you didn’t change the ORDS_PUBLIC_USER password during the above, please keep in mind that changing the password later could force you to reconfigure ORDS. Once the installation is over, ORDS built-in jetty server automatically start. You can access the APEX interface now from Use ctrl+c to kill the server.Now we will install and configure Apache Tomcat for the webserver serving ORDS. Version 9 was the latest one supported for ORDS, hence we will proceed with the same version. Keep on checking Oracle’s announcements to know when the later versions are certified for ORDS. Download the tar.gz file from the download repository & extract to /u01/apache-tomcat/Now switch to /u01/apache-tomcat/conf path and let us quickly make few modifications. As my server is already running Oracle EBS on port number 8005, I had to change this to next available port so that Apache Tomcat could go online.Edit the “server.xml” file and make the changes as with the image below and make sure that you are not running other application on the port 8080. If yes, you will have to reconfigure ORDS once again with the next available port (I am not sure whether it would truly affect incase if you are not using Standalone mode)Now we have to copy few files to Apache [email protected]:/home/oracle/Downloads/ords-latest>cp ords.war /u01/apache-tomcat/[email protected]:/home/oracle/Downloads/apex-latest/apex>scp -pr images /u01/apache-tomcat/webapps/iIt’s time to start Apache Tomcat server!
