Step 1- Download  latest version of java SDK,  install and configure the setup. At last set PATH Environment variable  to refer to the bin folder of your JDK  installation directory. e.g-

 

Here JDK install in JDK6.0 folder of E drive on your computer.

 

Step 2-  Download latest version of Tomcat from http://tomcat.apache.org/ . Once you downloaded, extract the Binary Distribution at any location (whichever location you want).  for example  in  E:\apache-tomcat-7.0.32 .

Tomcat server can be shutdown by double click on shutdown.bat file. shutdown.bat file is available in

                               E:\apache-tomcat-7.0.32\bin 

Step 3-  After successful start  of tomcat, you can check by this url http://localhost:8080/ , here 8080 is default port number.The result should be look like this:

now your tomcat server is working fine.Now we will see how to use Eclipse (IDE) to build and run Struts 2  web application.

Step 4 -  Download latest version of Eclipse(IDE)  from http://www.eclipse.org/downloads/  . Once you downloaded,  extract zip file to any desire location.For example in E:/eclipse/.
Eclipse can be started by double click on eclipse.exe available in  E:/eclipse/ folder.

Step 5- Now set up Struts 2 framework. For this  download latest version of struts 2 framework  from http://struts.apache.org/download.cgi.

• I downloaded struts-2.3.4.1-all.zip. Unzip this zip file  to any location. for example E:/struts-2.3.4.1.


•  E:/struts-2.3.4.1/lib folder contains all required jar files for struts 2 framework.


• And E:/struts-2.3.4.1/apps  folder contains some sample web application war files including struts2-blank.war file.


• struts2-blank.war file contains all configuration required  for running sample Struts 2 web application.

you can run run this sample using Eclipse like this:

•   import  war file  :  File ->import->choose struts2-blank.war file (in Eclipse).It should  look like this:

After importing  struts2-blank.war file, struts2-blank application directory structure look like this:

Now run this struts2-blank application, result on browser should be look like this:

Hope you will be feeling great as you run sample Struts 2  web application. In this sample struts 2 application ,you didn't do any configuration because it already have all the configuration.

In next part, we will learn Struts 2 configuration using Hello world  web application.
