###Download JDK latest version
Upload the files to the server
	put /home/huber/setups/jdk-6u22-linux-i586.bin.zip /home/murakas/huber/software
	put /home/huber/setups/apache-tomcat-7.0.4.tar.gz /home/murakas/huber/software
	put /home/huber/setups/jdk-6u22-linux-x64.bin /home/murakas/huber/software

Upload the files to the running instance
scp -i huber.private -r /home/murakas/huber/software root@172.17.60.52:/mnt

if files jdk can't be uploaded to the instance then, download it with wget (for example)
$ wget http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jdk-6u23-linux-x64.bin?BundledLineItemUUID=_qSJ_hCu0VwAAAEtMHlZDcQM&OrderID=7SiJ_hCuYEYAAAEtInlZDcQM&ProductID=6gGJ_hCwIQYAAAEsKIMcKluK&FileName=/jdk-6u23-linux-x64.bin


Installing jdk in an instance on the cloud, jdk which has to be installed on the instance is 64 bits 
Method 1
/mnt/jdk-6u22-linux-x64.bin
unzip jdk-6u22-linux-x64.bin
mv jdk1.6.0_22/ /usr/lib

create a symbolic link called jdk to JAVA_HOME
cd /usr/lib 
ln -s jdk1.6.0_22 jdk

Now we need to set the JAVA_HOME environment variable. Add the following at the end of /etc/profile just after export PATH.

JAVA_HOME="/usr/lib/jdk"
export JAVA_HOME

Register java command to be use in the command line
update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jdk1.6.0_23/bin/java" 1
update-alternatives --set java /usr/lib/jdk1.6.0_23/bin/java

	$java -version
	#Trying if java is installed correctly

Method 2
$ chmod +x jdk-6u34-linux-x64.bin
$ sudo ./jdk-6u34-linux-x64.bin
$ sudo mv jdk1.6.0_34 /usr/lib/jvm/

$sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_34/bin/java 1
$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_34/bin/javac 1
$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_34/bin/javaws 1

where, 1 is changed to 1064, 1065, etc., it depends on the currents in the system.

$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
$ sudo update-alternatives --config javaws

###Tomcat installation

Download apache-tomcat-7.0.4.tar.gz or any version you want
Untar the file
Move the folder to your prefered location, in my case, I used /usr/local/tomcat/
Which means that tomcat will start in that location, but to start it will need superuser privileges

Create “tomcat” Group & User
	$groupadd tomcat

	$useradd -g tomcat -d /usr/local/tomcat tomcat

	$usermod -G www-data tomcat

	$nano /etc/init.d/tomcat


#command to look for java alternatives
	$update-alternatives --config java

#Tomcat auto-start
#description: Auto-starts tomcat
#processname: tomcat
#pidfile: /var/run/tomcat.pid

#this path should point to your JAVA_HOME Directory
export JAVA_HOME=/usr/lib/jdk1.6.0_22/
case $1 in

start)
    sh /usr/local/tomcat/apache-tomcat-7.0.4/bin/startup.sh
  ;;

    stop)
     sh /usr/local/tomcat/apache-tomcat-7.0.4/bin/shutdown.sh
     ;;

    restart)
     sh /usr/local/tomcat/apache-tomcat-7.0.4/bin/shutdown.sh
     sh /usr/local/tomcat/apache-tomcat-7.0.4/bin/startup.sh
    ;;
esac

exit 0
	

	$chmod 755 /etc/init.d/tomcat

	$nano /usr/local/tomcat/conf/tomcat-users.xml

add at the end of the file
	<role rolename="manager"/>
	<role rolename="manager-gui"/>
	<role rolename="admin"/>
	<user username="admin" password="tomcat" roles="admin,manager,manager-gui"/>


	$/etc/init.d/tomcat start
