Can't loop and display a simple List of objects in Struts 2

Question

I have this class Dog.java and a List<Dog> that is passed to dogs.jsp page.

public class Dog {
    public String name;
    public String breed;

    public Dog(String name, String breed) {
        this.name = name;
        this.breed = breed;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getBreed() {
        return breed;
    }

    public void setBreed(String breed) {
        this.breed = breed;
    }
}

I try to display each dog, but although it does loop over all dogs in the list (displays table headers 5 times), it doesn't display the dogs names and breeds. Why?

<s:iterator value="dogs" status="x">
    <table>
        <tr>
            <th>Name</th>
            <th>Breed</th>
        </tr>

        <tr>
            <td><s:property value="%{#x.name}"></s:property></td>
            <td><s:property value="%{#x.breed}"></s:property></td>
        </tr>
    </table>
    <br/><br/>

</s:iterator>

status is for status, not each item in the iteration. You need to either use the var property, or just skip it and use %{name} etc. since the item of iteration is at the top of the value stack. Note that this information is contained in the documentation. — Dave Newton

<s:iterator value="dogs" var="dog">
  ...  <s:property value="#dog.name" />
 </s:iterator>

This worked for me:

<s:iterator value="dogs" status="x">
    <br/>
    <table>
        <tr>
            <th>Name</th>
            <th>Breed</th>
        </tr>

        <tr>
            <td><s:property value="%{name}"></s:property></td>
            <td><s:property value="%{breed}"></s:property></td>
        </tr>
    </table>
</s:iterator>
