Metacat

#!/bin/bash

#This script will install openjdk-7 and tomcat7.

#It will update the alternatives for java, javac, keytool and javaws to openjdk-7.

#It will modify the /etc/tomcat7/catalina.properties to allow DataONE idenifiers.

#It will modify the workers.properties file for apache-tomcat connector.

#It will move Metacat and other web applications from the old context directory to the new context directory.

#The user running the script should have the sudo permission.
