I followed the tutorial on the DataNucleus web site but I am stuck at
the enhancement part. I defined a class with annotations but the
enhancer does not recognize the annotations. I only use annotations so
I don't have any .jdo file.
My class is:
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
@PersistenceCapable
public class X {
@Persistent(primaryKey = "true")
private long id;
@Persistent
private String sValue;
@Persistent
private int iValue;
@Persistent
private double dValue;
private X() {
}
public X(String sValue, int iValue, double dValue) {
this.sValue = sValue;
this.iValue = iValue;
this.dValue = dValue;
}
}
The output of the Enhancer is:
