ClassNotFoundException enhancer

[Trenton D. Adams]

Caused by: java.lang.ClassNotFoundException: 
org.adamsbros.rmi.ledger.datatypes.EntryType

public enum EntryType implements Serializable
{
    DEBIT,
    CREDIT
}

I have it setup to store these as strings.  The class that is using it as 
this...

    @Column(name = "debitCredit")
    @Enumerated(EnumType.STRING)
    public EntryType getEntryType()
    {
        return entryType;
    }

Is the enhancer not loading it into the class path because there's a missing 
annotation of some sort?  What would that be?  I though the @Enumerated was all 
that is needed.

openjpa-1.2.1

Thanks.
