[castor-user] JDO: No convertor exists for converting type java.lang.String to

Mike Wannamaker Wed, 15 Sep 2004 09:45:13 -0700

I get the error below when trying to save an object using JDO? I have a Payment class that has a payment element which is type String and has an enumeration restriction of VISA, CHECK ..

I don't want to have a separate database table for these, what I want is castor to just write out to the payment table, payment column the value of the type. IE : VISA, CHECK ..

How can I do this?

TIA

Snippet from xsd file:

   <xs:element name="payment">
    <xs:annotation>
     <xs:documentation>The type of payment, VISA, MASTERCARD, CHECK, CASH.</xs:documentation>
    </xs:annotation>
    <xs:simpleType>
     <xs:restriction base="xs:string">
      <xs:enumeration value="VISA"/>
      <xs:enumeration value="MASTERCARD"/>
      <xs:enumeration value="CHECK"/>
      <xs:enumeration value="CASH"/>
     </xs:restriction>
    </xs:simpleType>
   </xs:element>
