Struts2-UI Tags Example-I

AIM:

To understand how to use some UI tags such as label, textfield, password, form, submit.

Problem:

Create textfield for username and create password for password.

If you give correct username and password , the display.jsp file will display.

Otherwise the failure.jsp will display.

PROCEDURE:

Step 1:

            Create project Named UITags-I

Step 2:

            Create Action class named UIAction

            Include following coding into UIAction

package example;

import com.opensymphony.xwork2.ActionSupport;

public class UIAction 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 UIAction()

    {

    }

    public String execute() throws Exception

    {

       if((getUsername().equals("suresh"))&&(getPassword().equals("kumar")))

       {

           return "success";

       }

       else

       {

           return "failure";

       }

    }

}

Step 3:

            Made some changes in struts.xml

< !DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
http://struts.apache.org/dtds/struts-2.0.dtd >

< struts >

< package name="example" namespace="/example" extends="struts-default" >
< action name="uiaction" class="example.UIAction" >
< result name="input" > /example/register.jsp < /result >
< result name="success" > /example/display.jsp < /result >
< result name="failure" > /example/failure.jsp < /result >
< /action >
< /package >
< /struts >

Step 4:

Create register.jsp

Include following code into register.jsp

< %@taglib uri="/struts-tags" prefix="s" % >
< html >
< head >
< title > Register Page < /title >
< /head >
< body >
< s:form action="uiaction" method="post" >
< s:textfield name="username" label="UserName"/ >
< s:password name="password" label="PassWord"/ >
< s:submit value="OK"/ >
< /s:form >
< /body >
< /html >

Step 5:

            Create display.jsp

< %@taglib uri="/struts-tags" prefix="s" % >
< html >
< head >
< title > Register Page < /title >
< /head >
< body >

< h1 > WELCOME < /h1 > < h2 > < s:property value="username" > < /s:property > < /h2 >

< /body >
< /html >

Step 6:

            Create failure.jsp

< %@taglib uri="/struts-tags" prefix="s" % >
< html >
< head >
< title > Register Page < /title >
< /head >
< body >
< h1 > Hello ! < s:property value="username"/ > -- Who Are You? < /h1 >
< h2 > Enter Correct Username and password < /h2 >
< /body >
< /html >

Step 7:
