Please help! Struts 2/Eclipse - List Object not displayed in JSP
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 being displayed.
You 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>
<s:iterator value="myList">
<s:property /><br>
</s:iterator>
</body>
</html>
