I have a problem mapping Java object to Customer Java datatype like this.
1. How can I make a reference key in table B to the id in table A?
2. org.exolab.castor.mapping.MappingException: No convertor exists for converting type ...
this is the error i get for mapping datatype A to integer, how to create my own converter?
..
<?xml version="1.0" encoding="UTF-8"?>
<mapping>
<class identity="id" key-generator="IDENTITY" name="B">
<map-to table="B"/>
*<field name="a" type="A">
<sql name="a" type="integer"/>
For the mapping above, just get rid of the 'type' attribute. Castor will automatically figure this out based on the mapping for the A class.
Please see the JDO examples (http://www.castor.org/examples.html) in the src/examples/jdo directory for examples of this.
