1. UBUNTU BASED

1.I. JAVA JDK

• Uninstall the open-jdk installed on your system:

  sudo apt-get update && sudo apt-get remove openjdk*
  

• Get JAVA JDK from Java openJDK, or other maintainer version like Oracle or Amazon and decompress:

  tar -zxvf jdk*.tar.gz
  

• Place it into the folder:

  sudo mkdir /usr/lib/jvm/jdk-21.0.3/
  sudo mv jdk*/ /usr/lib/jvm/jdk-21.0.3/
  

• Install the java alternatives:

  sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk-21.0.3/bin/java" 0
  sudo update-alternatives --set java /usr/lib/jvm/jdk-21.0.3/bin/java
  

• Install the javac alternatives:

  sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk-21.0.3/bin/javac" 0
  sudo update-alternatives --set javac /usr/lib/jvm/jdk-21.0.3/bin/javac
  

• In /etc/environment:

  sudo nano /etc/environment
  

  • Define JAVA_HOME:

        PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
        JAVA_HOME="/usr/lib/jvm/jdk-21.0.3"
    

• Refresh the environment:

  source /etc/environment
  

• Check Java compiler version:

  javac -version
  

  • Correct output example:

    javac 21.0.3
    

• Check Java VM version:

  java -version
  

  • Correct output example:

    java version "21.0.3" 2024-04-16 LTS
    Java(TM) SE Runtime Environment (build 21.0.3+7-LTS-152)
    Java HotSpot(TM) 64-Bit Server VM (build 21.0.3+7-LTS-152, mixed mode, sharing)
    

1.II APACHE MAVEN

• Download Apache Maven and decompress:

  tar -zxvf apache-maven-*.tar.gz
  

• Install Apache Maven on this folder:

   sudo mkdir /opt/apache-maven
   sudo chown user:user /opt/apache-maven/
   mv apache-maven-*/* /opt/apache-maven/
  

• In /etc/environment:

  sudo nano /etc/environment
  

  • Define MAVEN_HOME:

        PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/opt/apache-maven/bin"
        JAVA_HOME="/usr/lib/jvm/jdk-21.0.3"
        MAVEN_HOME="/opt/apache-maven"
    

• Refresh the environment:

  source /etc/environment
  

• Check Maven version:

  mvn --version
  

  • Correct output example:

    Apache Maven 3.9.6 (bc0240f3c744dd6b6ec2920b3cd08dcc295161ae)
    Maven home: /opt/apache-maven Java version: 21.0.3, vendor: Oracle Corporation,
    runtime: /usr/lib/jvm/jdk-21.0.3
    Default locale: es_ES, platform encoding: UTF-8
    OS name: "linux", version: "6.8.0-35-generic", arch: "amd64", family: "unix"
    

1.III APACHE TOMCAT

• Download Apache Tomcat and decompress:

  tar -zxvf apache-tomcat-*.tar.gz
  

• Install Apache Tomcat on this folder:

  sudo mkdir /opt/apache-tomcat
  sudo chown user:user /opt/apache-tomcat/
  mv apache-tomcat-*/* /opt/apache-tomcat/
  

• In /etc/environment:

  sudo nano /etc/environment
  

  • Define CATALINA_HOME:

        PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/opt/apache-maven/bin:/opt/apache-tomcat/bin"
        JAVA_HOME="/usr/lib/jvm/jdk-21.0.3"
        MAVEN_HOME="/opt/apache-maven"
        CATALINA_HOME="/opt/apache-tomcat"
    

• Refresh the environment:

  source /etc/environment
  

• Check Maven version:

  catalina.sh version
  

  • Correct output example:

    Using CATALINA_BASE:   /opt/apache-tomcat
    Using CATALINA_HOME:   /opt/apache-tomcat
    Using CATALINA_TMPDIR: /opt/apache-tomcat/temp
    Using JRE_HOME:        /usr/lib/jvm/jdk-21.0.3
    Using CLASSPATH:       /opt/apache-tomcat/bin/bootstrap.jar:/opt/apache-tomcat/bin/tomcat-juli.jar
    Using CATALINA_OPTS:   
    Server version: Apache Tomcat/10.1.25
    Server built:   Jun 14 2024 19:31:59 UTC
    Server number:  10.1.25.0
