JAXB unmarshaling issue

I am attempting to unmarshal an XML file. However, I end up with : 

unexpected element (uri:"", local:"show-list"). Expected elements are <{}showList>

My code:

Show: 

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = { "title", "description", "host", "logo", "feed" })
public class Show {
    private String title;
    private String description;
    private String host;
    private String logo;
    private String feed;  
        // getter, setter  

}

ShowList: 

@XmlRootElement
public class ShowList {

    @XmlElementWrapper(name = "shows")
    @XmlElement(name = "show")
    private ArrayList<Show> shows;

    public ArrayList<Show> getList() {
        return shows;
    }

    public void setList(ArrayList<Show> shows) {
        this.shows = shows;
    }

}

XML: 

<?xml version="1.0" encoding="utf-8"?>
<show-list count="23">
    <show>
        <title>TQA Weekly</title>
        <description>

    </show>  
...  
</show-list>

main() 

public static void main(String[] args) {
        JAXBContext context;
        try {
            context = JAXBContext.newInstance(ShowList.class);
            Unmarshaller um = context.createUnmarshaller();
            ShowList list = (ShowList) um.unmarshal(new File("D:/Program Files/apache-tomcat-7.0.35-windows-x86/apache-tomcat-7.0.35/webapps/xml/show.xml"));
            System.out.println(list.getList().size());
        } catch (JAXBException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

Where have I made a mistake?

Set the value of your @XmlRootElement name attribute

@XmlRootElement(name = "show-list")

otherwise JAXB uses the name of the class.

Also, get rid of 

@XmlElementWrapper(name = "shows")

That would work if your XML was like 

<show-list count="23">
    <shows>
        <show>
            <title>TQA Weekly</title>
            <description>
