Configure the JDK's path path to run Javac and Java, regardless of directory

Export java_home=/usr/local/jdk1.6.0_45
Export path= $PATH:/usr/local/jdk1.6.0_45/bin
Export classpath=.:/ Usr/local/jdk1.6.0_45/lib/dt.jar:/home/jdk1.6.0_45/lib/tools.jar
Export Java_home PATH CLASSPATH

Join the path after extracting Tomcat

Export catalina_home=/usr/local/apache-tomcat-7.0.53
