Hi Everyone,
I'm new to Struts. Please help me figure out why the List myList is not
being displayed in JSP, although my String variable s is displayed. Your
help will be greatly appreciated! Thanks!
Here's the code:
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>
<include file="struts-default.xml"/>
<package name="default" extends="struts-default">
<action name="getAllEmployees" method="getAllEmployees"
class="net.struts2demo.action.EmployeeAction">
<result>employees.jsp</result>
</action>
</package>
</struts>
Action class
package net.struts2demo.action;
import com.opensymphony.xwork2.ActionSupport;
import com.sample.PersonController;
import com.sample.Person;
import java.util.List;
import java.util.ArrayList;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
public class EmployeeAction extends ActionSupport {
//private static Logger logger = Logger.getLogger(EmployeeAction.class);
private Person person;
private List<String> myList;
private String s;
public List<String> getMyList() {
return myList;
}
public String getS(){
return s;
}
public String getAllEmployees() {
//PersonController pc = new PersonController();
//List people = pc.getAllPeople();
//logger.log(Level.TRACE, "Action Class: And a trace message
using log()
method.");
System.out.print("Action Class");
List<String> myList = new ArrayList<String>();
myList.add("Fruits");
myList.add("Apple");
myList.add("Mango");
myList.add("Orange");
myList.add("Pine Apple");
s="Hello Struts was in the right method!";
return SUCCESS;
}
public String getPerson() {
PersonController pc = new PersonController();
person = pc.getPerson(1);
return "success";
}
public void setPerson(Person person) {
this.person = person;
}
public void setMyList(List<String> myList) {
this.myList = myList;
}
}
JSP Page: employee.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Iterator Tag Example!</title>
</head>
<body>
<h1>Iterator Tag Example!</h1>
<s:iterator value="myList">
<s:property /><br>
</s:iterator>
<table align="center" class="borderAll">
<tr><td class="tdLabel"><s:text name="s"/></td>
<td><s:textfield name="s" size="30"/></td>
</tr>
</table>
</body>
</html> >
