*.jsp file
Step_4.1:Create HelloWorld.jsp
Right click on example under web pages.
Newàotherà under categories web – under File types jsp
Give jsp file name as HelloWorld.jsp
Include following coding into HelloWorld.jsp
< %@ page contentType="text/html; charset=UTF-8" % >

< html >
< head >

< title > Login Application < /title >
< /head >
< body >
< h2 > Success < /h2 >
< /body >
< /html >
Step_4.3: Create failure.jsp

< body >
< h2 > Failure < /h2 >
< /body >
< /html >
Step_5: Creating action file
Source Package
|
|
example
|
|
*.java
Step_5.1:Create HelloWorld.java under source package
Include following coding
package example;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport
{
private String username;
private String password;
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
public String getUsername()
{
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String execute() throws Exception
{
if(getUsername().equals("suresh")&&(getPassword().equals("kumar")))
{
return "success";
}
else
{
return "failure";
}
}
}
Step_6: Configuration file
There are two configuration file
One is example.xml
Another one is struts.xml
Source Package
|
|
< default-package >
|
|
example.xml
struts.xml
example.xml
include following code into example.xml
…….
…….
< struts >
< package name="example" namespace="/example" extends="struts-default" >
< action name="login" class="example.HelloWorld" >
< result > /example/HelloWorld.jsp < /result >
< result name="success" > /example/success.jsp < /result >
< result name="failure" > /example/failure.jsp < /result >
< /action >
< /package >
< /struts >
struts.xml
include following coding into struts.xml
……
……
< struts >
< include file="example.xml"/ >
< !-- Configuration for the default package. -- >
< package name="default" extends="struts-default" >
< /package >
</struts >
Step_7:
Run HelloWorld.jsp à right click on HelloWorld.jspà run file
