Struts2 Data control Text tag Example

Struts2 Text Tag Example

Aim:

Text tag is a generic tag that is used to get values from properties. The properties file is saved where the java file is saved.

There are three ways to use text tag.

1). To get values from *.properties file

2). If the body of the text tag is not specified, the name of the text tag will display.

3). If the body of the text tag is specified, the body of the tag will display.

Procedure:

          Step 1:

          Create Project name as DataTextPro

          Step 2:

          Create Action as HelloWorld.java

          Include following coding within the

package example;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorld extends ActionSupport

{

    public String execute() throws Exception

    {

       

        return "success";

    }

 

}

Step 3:

Create jsp file

HelloWorld.jsp

< /head >

< body >
< s:text name="body not.message" > < /s:text >


< s:text name="message" > sureshkumar, welcome< /s:text >


< /body >
< /html >

Step 4:

Made some changes in struts.xml

            You have known how to create project for struts2 using Netbean6.8.

Step 1:

            Create project name as AnnotationPro

Step 2:

            Create LoginAction

            Add following coding into LoginAction.java

package example;

import com.opensymphony.xwork2.ActionSupport;

import com.opensymphony.xwork2.validator.annotations.RequiredStringValidator;

import com.opensymphony.xwork2.validator.annotations.Validation;

@Validation

public class LoginAction extends ActionSupport

you don’t give both username and password

Struts2 UI checkboxlist and select Tags

UI Form Tags – checkboxlist and select Tags

Aim:

To understand how to create checkboxlist and select tag in struts2 using list property in &lt s:checkboxlist list=” ” &gt and &lt s:select list=” “ &gt .

The checkboxlist tag is UI tag. It is used to create series of checkboxes from a list

We will understand the checkboxlist and select tags from following coding.

Requirement:

            Jsp files

                        a). home.jsp

                        b). checklist.jsp

                        c). result.jsp

            Action files

                        a). CheckAction.java

            configuration files

                        struts.xml

Directory structure of this project.

 Note:

         You have already known how to create Project for Struts2 such as SureshS.

Procedure:

Step 1:

            Create home.jsp

            Coding for home.jsp

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

< title > Home Page < /title >
< /head >
< body >
< s:form action="check" >
< s:submit/ >
< /s:form >
< /body >
< /html >

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 >
< /head >
< body >

< s:form action="result" >

< s:checkboxlist list="colors" name="yourColor" value="defaultColor" / >
< 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.*;

import org.apache.commons.logging.Log;

public class CheckAction extends ActionSupport

{

    private List colors;

    private String yourColor;

    private List country;

    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

< ?xml version="1.0" encoding="UTF-8" ? >
< !DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
http://struts.apache.org/dtds/struts-2.0.dtd >

< struts >

< constant name="struts.devMode" value="true" / >

< package name="example" namespace="/example" extends="struts-default" >

< action name="check" class="example.CheckAction" >
< result name="input" > /example/home.jsp < /result >
< result name="success" > /example/checklist.jsp < /result >

< /action >
< action name="result" class="example.CheckAction" >

< result name="success" > /example/result.jsp < /result >

< /action >
< /package >

< /struts >


Step 6:

Run home.jsp

In home.jsp, the button will display. You click on the button, the control will go to checklist.jsp, where you select color from checkboxlist and select country from select tag. And click button the result.jsp will display. Where the selected colors and selected country will display.

You run home.jsp

You will get like below

click Submit

where you may select any if you select RED and Green from checkboxlist

select India from select tag.

You will get output
