I'm trying to use Hibernate to persist a class that looks like this:

public class Item implements Serializable, Comparable<Item> {

// Item id
private Integer id;

// Description of item in inventory
private String description;

// Number of items described by this inventory item
private int count;

 //Category item belongs to 
private String category;

// Date item was purchased 
private GregorianCalendar purchaseDate;

    public Item() {
}

    public Integer getId() {
    return id;
}

public void setId(Integer id) {
    this.id = id;
}

    public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}   

public int getCount() {
    return count;
}

public void setCount(int count) {
    this.count = count;
}

public String getCategory() {
    return category;
}

public void setCategory(String category) {
    this.category = category;
}

public GregorianCalendar getPurchaseDate() {
    return purchaseDate;
}

public void setPurchasedate(GregorianCalendar purchaseDate) {
    this.purchaseDate = purchaseDate;
}

My Hibernate mapping file contains the following:

<property name="puchaseDate" type="java.util.GregorianCalendar">
  <column name="purchase_date"></column>
</property>

When I try to run, I get error messages indicating there is no getter function for the purchaseDate attribute:

I'm new to Hibernate, so I don't know all the ins and outs, but I do have the getter and setter for the purchaseDate attribute. I don't know what I'm missing here - does anyone else? Thanks!
