This page is for Tomcat and Java Development

Install Tomcat for Development

My Env

  • Windows 7 64bit
  • Eclipse4.3 KEPLER
  • Tomcat7(42)


  1. Install Java(JDK) and Eclipse
  2. Download and Unzip Tomcat
  3. Install Tomcat plugin in Eclipse
  4. Setting in Eclipse
  5. Check

Install for Windows

Windows and Linux, Mac are same steps
I strongly recommended zip or tar.gz version, not use installer version for development.
Certainly, installer version is easy to install and manage, but not flexible for development.

Install Java(JDK) and Eclipse

If you install only JRE, please install JDK instead
Install Java and Eclipse is just straight forward. No explanation.


Set JAVA_HOME env(optional)

This is Java JDK path.
By default, C:\Program Files\Java\jdk1.7.0_40\bin is java home.
Add new environment variable for Windows

Download and Unzip

Download Tomcat and unzip under c: The name is long, I thought. Change “tomcat7”.
Unzip under c:tomcat7

Install Tomcat plugin in Eclipse

Download plugin form Eclipse Totale.


Decompress com.sysdeo.eclipse.tomcat_x.x.x and save it into eclipse\dropins
dropins folder is under eclipse you installed. In my case c:\eclipse\dropins.
That’s all. You restart eclipse, you can see tomcat mark on the top tool bar


Next is eclipse tomcat setting. To use Tomcat from eclipse, we need setting.
Eclipse “Window”-> “Preferences” -> “Tomcat7”
Please select Tomcat version(in this case Tomcat7) and select tomcat7 directory.


Other is not required to change.


Let’s check tomcat7 works.
Press tomcat button at the top of eclipse(withing red frame)
Tomcat runs and display log on eclipse console
Default application location is C:\tomcat7\webapps\ROOT
Access http://localhost:8080, you can see default application page.

Can I use multiple Tomcat in same machine?

Yes we can. It’s just process
Actually, I use 2 tomcat in same machine and test 2 Web applications which uses different tomcat process and port.

Create Easy Application for Development

Context file

This mean TOMCAT_HOME/conf/Catalina/localhost, ROOT.xml is root application, you can access this at the top page
if you want to change path, please use other name, for example application.xml etc…

Name Description
TOMCAT_HOME Tomcat install directory
Catalina Tomcat Engine name(described in server.xml)
localhost Host name(described in server.xml)


<?xml version="1.0"?>
<Context reloadable="true"
Name Description
workDir Working directory tomcat extract compiled jsp or servlet
docBase Context root, for development, this is Eclipse project directory
reloadable Whether reload setting, if you change sources automatically
path Application URL path

Real application

Basically, we prepared .war file for application
In application, we run application as root, so ROOT.xml as context file(TOMCAT_HOME/conf/Catalina/localhost/ROOT.xml).
And, ROOT.xml is

<Context path=""

Set full path of war file as docBase
