| [eclipselink-users] @Convert, Custom Mapping Problem |
|
Hi, switching from Oracle Toplink to
EclipseLink 1.0.1 i get an Exception in eclipseLink when
using a Converter which should map from Boolean to String
(YES, NO). In Toplink (older) it works fine. Here is my Entity Class, persistence.xml
and the exception stacktrace. ############################################################################## @Entity @Table(name = "PERSON", schema = "SYNCRO") @Inheritance(strategy=InheritanceType.SINGLE_TABLE) @Converter(name="ConverterBoolean",
converterClass=jpa.ConverterBoolean.class) abstract public class Person extends OMSBean implements
java.io.Serializable { ... @Column(name = "adult", nullable = false, length = 80) @Convert("ConverterBoolean") protected boolean adult; public boolean isAdult() { return adult;} public void setAdult(boolean adult) { PropertyChangeEvent pce = new
PropertyChangeEvent(this, "adult", this.adult, adult); this.adult = adult; this.firePropertyChange(pce); } ... ... ############################################################################## Persistence.xml: <persistence-unit name ="pu-oracle"> <description>Basic javaSE
