I have this mapping:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
  "-//Hibernate/Hibernate Mapping DTD 2.0//EN"
  "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
    <class name="se.barnvagnsfabriken.shop.beans.Order" table="Orders">
        <id name="id" column="id">
            <generator class="native"/>
        </id>
        <property name="payment" />
        <property name="delivery" />
        <property name="name" />
        <property name="address" />
        <property name="phone" />
        <property name="fax" />
        <property name="mobile" />
        <property name="eMailAddress" />
        <property name="submitted" />

        <!-- the order queue -->
        <many-to-one name="queue" class="se.barnvagnsfabriken.shop.beans.OrderQueue" />

        <!-- the order rows -->
        <set name="orderRows" lazy="true" inverse="true">
            <key column="order" />
            <one-to-many class="se.barnvagnsfabriken.shop.beans.OrderRow" />
        </set>

    </class>
</hibernate-mapping>


And an excerpt from se.barn...Order.java: (notice the double getter and setter methods)
Code:
    /**
     * Getter for property eMailAddress.
     *
     * @return Value of property eMailAddress.
     */
    public String getEMailAddress() {
        return this.eMailAddress;
    }
    public String geteMailAddress() {
        return getEMailAddress();
    }

    /**
     * Setter for property eMailAddress.
     *
     * @param eMailAddress New value of property eMailAddress.
     */
    public void setEMailAddress(String eMailAddress) {
        this.eMailAddress = eMailAddress;
    }
    public void seteMailAddress(String eMailAddress) {
        setEMailAddress(eMailAddress);
    }


If I remove [get|set]eMailAdress methods, Hibernate complaints that it can't find setter/getter methods for property eMailAddress. Is this me mistaking thinking the defualt getter/setter should be named with the e in upper case, like getEMailAddress?

Stack trace from exception thrown upon Configuration, with an Order class without geteMailAddress(), only getEMailAddress():

Good. I'll just have to read up on the specs again. It might even say why there's an exception to the "rule of thumb"; capitalize the property name.
