In the previous tutorials we covered how to configure Struts to map a URL such as hello.action to a Action class such as HelloWorldAction (specifically the execute method).

<action name="hello" class="org.apache.struts.helloworld.action.HelloWorldAction" method="execute">
	<result name="success">/HelloWorld.jsp</result>
</action>

...

In method execute is where we placed what we want this controller to do in response to the hello.action.

public String execute() throws Exception {
		
	messageStore = new MessageStore() ;
		
	helloCount++;
		
	return SUCCESS;

}

...

In the Using Struts 2 Tags example application we added a Struts 2 form to index.jsp.

<s:form action="hello">

	<s:textfield name="userName" label="Your name" />
	
	<s:submit value="Submit" />

</s:form>

...

For the example application associated with this tutorial add the following Java code to class HelloWorldAction.

	private String userName;

	public String getUserName() {
		return userName;
	}

	public void setUserName(String userName) {
		this.userName = userName;
	}

To personalize the MessageStore message (recall that class MessageStore is storing the message to display) add the following Java code to the HelloWorldAction's execute method after the statement that instantiates the MessageStore object.

if (userName != null) {
			
	messageStore.setMessage( messageStore.getMessage() + " " + userName);
			
}
