I have installed the tomcat and Java on my Amazon EC2 Instance by followingthe instructions on the following tutorial. http://sites.google.com/site/amistrongeryet/setting-up-java-tomcat-on-ec2. But after installing when I run the "updatedb; locate javac | grep bin" command it did not recognize the update and locate command and gives me the error message locate: command not found and after installing the tomcat everything went sommoth during installation according to the instructions in above mentioned tutorial but at the end when I run the command "bin/startup.sh" and try to navigate the url http://my_public_dns_key:8080 it gives me the connection timed out error.

Also please find below the command reference for my linux commands that I am using to run Java and tomcat.

In shell, which javac, what do you got? Command not found? –  Coder4 Sep 28 '11 at 11:46
    
updatadb is just for you can use locate, you may refer the location of javac by system environment setting. –  Coder4 Sep 28 '11 at 11:46
    
This is not an answer to your question but it might be a solution for your problem: take a look at Amazon's Elastic Beanstalk. Instead of a linux instance you get a tomcat instance. –  Kees de Kooter Sep 28 '11 at 11:48

Here are the steps I documented for myself in setting up java and tomcat in a 32 bit small instance. (lame that they support 32/64 bit on micro, but only 32 bit on small!)

Installing Tomcat

# make the directory that is going to hold tomcat
sudo mkdir /opt/tomcat
cd /opt/tomcat
# download tomcat
curl http://mirror.olnevhost.net/pub/apache/tomcat/tomcat-6/v6.0.29/bin/apache-tomcat-6.0.29.zip > tomcat6.zip
unzip tomcat6.zip
# now go into apache-tomcat-.../conf/server.xml and change all 8080 to 80 so we are running on the regular web port.
# then start tomcat.
sudo /opt/tomcat/apache-tomcat-.../bin/startup.sh

I later change it to use sudo wget http://apache.tradebit.com/pub/tomcat/tomcat-7/v7.0.16/bin/apache-tomcat-7.0.16.tar.gz

At this point, you should be able to hit http:/// and get the tomcat management page.

Installing Sun JDK 6 Download Sun JDK 6. You must agree to the terms and conditions in order to download, so I think you'll have to download and then sftp it over. I downloaded from http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html the 32 bit .bin version.

unzip the jdk into /opt/jdk1.6.xxx and then install it as a java alternative using the following:

sudo alternatives --install /usr/bin/java java /opt/jdk1.6.0_26/bin/java 1500
sudo alternatives --install /usr/lib/jvm/jre jre /opt/jdk1.6.0_26 1500
sudo alternatives --set java /opt/jdk1.6.0_26/bin/java
sudo alternatives --set jre /opt/jdk1.6.0_26

Then make sure you are running java by checking java -version. Since tomcat will be starting as root, I used sudo to test it.

$ sudo java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

Both the links for tomcat are dead. Please advice. –  Sohail Khan Sep 28 '11 at 17:45
    
go to the tomcat download page and find whatever version you need and get the appropriate url from that download page. –  digitaljoel Sep 28 '11 at 19:12
    
I have done the following steps to install tomcat but no success 1- make the dir tomcat in opt 2- download the tomcat6 in tomcat folder 3- unzip the zip file in tomcat folder 4- do the necessary changes in conf/server.xml 5- run the bin/startup.sh file and it gives me the command not found. –  Sohail Khan Sep 29 '11 at 17:50
    
make sure the script is executable and you have the correct path. –  digitaljoel Sep 29 '11 at 19:44

Have you checked that the security group of that instance allows inbound connections to port 8080

It looks as if Tomcat had started. Run

sudo fuser -v -n tcp 8080

It should output something like:

                     USER        PID ACCESS COMMAND
8080/tcp:            tomcat      pid F.... java

Then probe Tomcat right from the instance using wget or curl:

wget --spider localhost:8080

If you get 200 OK in response, it must be the firewall settings that prevent connection. Check your security group setting as David has already suggested - there must be a Custom TCP rule for port 8080.

You may also find it easier to install Java and Tomcat from the repo next time. There is a step-by-step guide for Amazon Linux in my article on Tomcat and EC2.
