Hello Forum,
I have a problem with EclipseLink.
I want to persist object attributes with a converter like in the following example:
@Entity
@Converter(
converterClass=ConverterJTextAreaToString.class,
name="ConverterJTextAreaToString"
)
public class MyEntity {
@Convert("ConverterJTextAreaToString")
@Column(name = "MY_TEXT", nullable=true, length=4000)
private JTextArea myTextArea;
public JTextArea getMyTextArea) {
return myTextArea;
}
}
In principle this works fine.
However, I also generate my tables with JPA (eclipselink.ddl-generation = create-tables), and whenever I use Converters JPA creates the columns as of type varchar with a length of 255.
The length attribute in the @Column annotation is just ignored, as well as the Java data type returned by the Converter.
Does anyone know how to set the data type with its attribute for a column when using a Converter?
Regards,
Mik
