Install and Run Tomcat windows

I am explaining every step to run tomcat in window and how to setup your projects and running Servlets.

1. Install JDK before installing tomcat.

  a) I installed JDK1.6.0 onC:\Java\jdk1.6.0

NOTE: Do not installed JDK under C:\Program Files. I just faced problem after setting my
environment variable on Window Xp.

2. Download the latest version of tomcat.
tomcat.apache.org , i downloaded Apache Tomcat 7.0.65.I rename downloaded folder to "apache-tomcat" and placed it at E:\apache-tomcat.Go to "Start" --> "My Computer" --> Right click--> "Property"--> Click "Advance Tab" --> "Environment Variables" --> Opens a window where you have to create new Environment Variables As Written Below

/* Under User Variable click New */
Variable Name CATALINA_HOME
Variable Value E:\apache-tomcat , Press ok
Variable Name JAVA_HOME
Variable Value C:\Java\jdk1.6.0, Press ok
Variable Name JAVA_HOME
Variable Value C:\Java\jdk1.6.0, Press ok
Variable Name PATH
Variable Value C:\Java\jdk1.6.0\bin, Press ok
// Under System Variable click New
Variable Name CALSSPATH
Variable Value C:\Java\jdk1.6.0\bin;E:\apache-tomcat\lib\servlet-api.jar, Press ok

3. Now We have to edit configuration files E:\apache-tomcat\conf folder

Open file context.xml find line/xml tag <Context>
and replace by <Context reloadable="true">
<servlet>...</servlet> inside this tag find
<param-value>false</param-value> 
and replace with <param-value>true</param-value>
Open file tomcat-users.xml and placed below code inside<tomcat-users>...</tomcat-users>

<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="boy108zon" password="boy108zon" roles="manager-gui,admin-gui"/>

4.Restart your computer. After above steps configuration. Lets create a new project.

1. I created a folder called store in E:\apache-tomcat\webapps\
2. Create Structure under

store(Project Folder) ---> WEB-INF(DIR) --> classes(DIR) , web.xml (FILE)
classes(DIR)-->HelloWorld.java (File)

3. Placed below xml code in web.xml created as above

  <?xml version="1.0" encoding="ISO-8859-1"?>
    <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">
   <web-app>
    <servlet>
     <servlet-name>HelloWorld</servlet-name>
     <servlet-class>HelloWorld</servlet-class>
    </servlet>
    <servlet-mapping>
     <servlet-name>HelloWorld</servlet-name>
     <url-pattern>/</url-pattern>
    </servlet-mapping>
  </web-app>

4. Open http://localhost:8080/ You can see Tomcat Statup Page , you can click on Mange App it will ask you to enter username and password , As you putted OR placed in tomcat-users.xml.

 

Here you can see list of Application running or deploy. if you further check our created application also visible to this list , you can Start , Stop , Reload , Undeploy your application here. Click on start so that our created application can be start.

 

5. That's all , Now open http://localhost:8080/store/ and you will see your HelloWorld Running.
