Struts2 - Combobox Tag (Form Tags)

The struts2 combobox is basically an HTML INPUT of type text and HTML SELECT grouped together to give you a combo box functionality. You can place text in the INPUT control by using the SELECT control or type it in directly in the text field.

Add the following code snippet into the struts.xml file.

struts.xml
<action name="comboboxTag" class="net.struts2.comboboxTag">
   <result>/pages/uiTags/comboboxTag.jsp</result>
</action>

Create "comboboxTag" action class and a list in the class and populate it with various items as shown in the class.

comboboxTag.java
package net.struts2;
import com.opensymphony.xwork2.ActionSupport;
import java.util.*;

public class comboboxTag extends ActionSupport{
  
  private List fruits;
  public String execute()throws Exception{
  fruits = new ArrayList();
  fruits.add("Apple");
  fruits.add("Mango");
  fruits.add("Orange");
  fruits.add("Pine Apple");
  return SUCCESS;

  }

  public List getFruits(){
  return fruits;
  }
}


Create a jsp using the combobox tag


The first struts2 combobox tag prints a combobox with name Color name and an HTML INPUT of type text and HTML SELECT grouped together created using the list.

The second
struts2 combobox tag prints a combobox with name Fruits name and an HTML INPUT of type text and HTML SELECT grouped together created using the "fruits" list of the action class.

comboboxTag.jsp

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

<html>
  <head> 
  <title>Combobox  (Form Tag) Tag Example!</title>
  <link href="<s:url value="/css/main.css"/>" rel="stylesheet"
  type="text/css"/>
  </head>
  <body>
  <h1><span style="background-color: #FFFFcc">Combobox 
   Tag Example!</span></h1>
  <s:form>
  <s:combobox label="Colors Name" name="colorNames" 
   headerValue="--- Please Select ---"
  headerKey="1" list="{'Black','Green','White','Yellow',
  'Red','Pink'}" /><br>
  
  <!-- Use array list --><br>
  <s:combobox label="Fruits Name" name="fruitsNames"
    headerValue="--- Please Select ---"
  headerKey="1" list="fruits" />
  </s:form>
  </body>
</html>

Add the following code snippet into the struts.xml file. struts.xml <action name="radioTag" class="net.struts2.checkboxlistTag">   <result>/pages/uiTags/radioTag.jsp</result> </action> Create an action class with two lists as shown below: checkboxlistTag.java package net.struts2; import com.opensymphony.xwork2.ActionSupport; import java.util.*; public class checkboxlistTag extends ActionSupport{      private List fruits;   private List animals;     public String execute()throws Exception{   fruits = new ArrayList();   fruits.add("Apple");   fruits.add("Mango");   fruits.add("Orange");   fruits.add("Pine Apple");   animals = new ArrayList();   animals.add("Dog");   animals.add("Elephant");   animals.add("Ox");   animals.add("Fox")

Global Action Forwards and Action Mappings

What is an action forward? A action forward can be used to forward to a jsp or action mapping. There are two different action forwards. The global action forward and the local action forward. You can access a global action forward on each jsp or action class. A local action forward can only be accessed by the assigned action class. What is a action mapping? The action mapping is the heart of struts. It managed all actions between the application and the user. You can define which action will be executed by creating a action mapping. The diagram show you, how the application server manage the request of the index.jsp or a non existing action mapping. In the first step we create a new action mapping. Open the struts-config.xml, you will find it in the folder WebRoot/WEB-INF. Right click in the outline window on action-mapping. Choose Use Case default and Action Type Forward. The Forward Path is the welcome page /jsp/index.jsp In the second step you create a global act
