Struts2 Data control Action Tag Example

Struts2 Action Tag Example

Aim:

            Action tag is used to call action directly from jsp in struts2 framework.

Note:

            I have already explained how to create struts2 project and folders for storing jsp file and for stroing action class file. I also explained where we configure the project.

Procedure:

           

Step 1:

            Create Project name as ActionTag

Step 2:

            Create Action class HelloWorld

package example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorld extends ActionSupport

{

    String greetings = null;

    public String execute() throws Exception

    {

        setGreetings("Hello World");

        return SUCCESS;

    }

    public String getGreetings()

    {

        return greetings;

    }

    public void setGreetings(String greetings)

    {

        this.greetings = greetings;

    }

}

                       

Step 3:

            Create index.jsp file

Step 2:

            Create checklist.jsp

            Coding for checklist.jsp

< %@taglib uri="/struts-tags" prefix="s" % >
< html >
< head >
< meta name="keywords" content="example for checkboxlist, select " >

< title > CheckboxList Page < /title >

< s:select list="country" name="yourCountry"/ >
< s:submit/ >

< /s:form >
< /body >
< /html >

Step 3:

Create result.jsp


< %@taglib uri="/struts-tags" prefix="s" % >
< html >
< head >
< meta name="keywords" content="example for checkboxlist, select " >

< title > CheckboxList Page < /title >

< /head >
< body >

select color: < s:property value="yourColor" / >
Your Country: < s:property value="yourCountry"/ >

< /body >
< /html >

Step 4:
CheckAction.java

package example;

import com.opensymphony.xwork2.ActionSupport;

import java.util.*;

    private String yourCountry;

    public List getCountry() {

        return country;

    }

    public void setCountry(List country) {

        this.country = country;

    }

    public String getYourCountry() {

        return yourCountry;

    }

    public void setYourCountry(String yourCountry) {

        this.yourCountry = yourCountry;

    }

    public List getColors()

    {

        return colors;

    }

    public void setColors(List colors)

    {

        this.colors = colors;

    }

    public String getYourColor() {

        return yourColor;

    }

    public void setYourColor(String yourColor) {

        this.yourColor = yourColor;

    }

    public CheckAction()

    {

        colors=new ArrayList();

        colors.add("RED");

        colors.add("Blue");

        colors.add("Green");

        colors.add("Cycan");

        country=new ArrayList();

        country.add("India");

        country.add("Pakistan");

      

    }

    public String execute() throws Exception

    {

      

        return "success";

    }

}

Step 5:

            Made some changes in struts.xml

Struts2-ActionMessage and ActionError

Struts2 ActionMessage and ActionError

AIM:

            From this post we will learn how to validate the user input .

Purpose:

            If the error occur , the actionmessage will display.
