Re: Failing to persist a field where the type is XMLGregorianCalendar.

[garpinc]

here are the 2 classes involved in the annotation
package com.cambridgesemantics.anzo.relationalreplicator.openjpaplugin;

import javax.xml.datatype.DatatypeConfigurationException;
import javax.xml.datatype.DatatypeFactory;

import org.apache.openjpa.jdbc.kernel.JDBCStore;
import org.apache.openjpa.jdbc.meta.ValueMapping;
import org.apache.openjpa.jdbc.meta.strats.AbstractValueHandler;

public abstract class XGCAbstractValueHandler extends AbstractValueHandler {
    @Override
    public Object toObjectValue(ValueMapping vm, Object val) {
        if (val == null)
            return null;
        try {
            return
DatatypeFactory.newInstance().newXMLGregorianCalendar(val.toString());
        } catch (DatatypeConfigurationException e) {
            e.printStackTrace();
            return null;
        }
    }

    @Override
    public Object toDataStoreValue(ValueMapping vm, Object val, JDBCStore
store) {
        if (val == null || !(val instanceof
javax.xml.datatype.XMLGregorianCalendar))
            return null;

        javax.xml.datatype.XMLGregorianCalendar date =
(javax.xml.datatype.XMLGregorianCalendar) val;
        return date.toGregorianCalendar().getTime();
    }

}
