JAXB unmarshall a collection

I have an XML doc:

<?xml version="1.0" encoding="UTF-8"?>

<Log>
    <logEntry>
       <severity>WARN</severity>
       <dateTime>2011-03-17 15:25</dateTime>
       <message>Here is the text from the application</message>
       <class>(class name)</class>
       <program> TB Reception</program>
    </logEntry>

    <logEntry>
       <severity>WARN</severity>
       <dateTime>2011-03-17 15:25</dateTime>
       <message>Here is the text from the application</message>
       <class>(class name)</class>
       <program> TB Reception</program>
    </logEntry>
</Log>

and two POJOs:

package org.jwes.jaxb.jax;

import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="Log")
public class Log {
    @XmlElementWrapper(name = "logEntry")
    private List<LogEntry> logList;

    public List<LogEntry> getLogEntries() {
        return logList;
    }

    public void setLogEntries(List<LogEntry> logList) {
        this.logList = logList;
    }


}

package org.jwes.jaxb.jax;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlElementWrapper;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(name="LogEntry")
public class LogEntry{


    private String source;
    private String message;
    private String severity;
    private String program;
    private String className;


    public String getSource() {
        return source;
    }
    public void setSource(String source) {
        this.source = source;
    }
    public String getMessage() {
