I've been trying to work out what I'm doing wrong with the following
code. It was working last night, and as far as i can remember I
haven't changed it.
I have search for hours for a solution but i only seem to find the
error in relation to compound keys online.
Here's the code:
package my.syncdroidserver;
import java.util.ArrayList;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Box {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private final int boxID;
@Persistent
private final AppUser owner;
@Persistent
private final String boxName;
@Persistent
private ArrayList<AppUser> readers;
public int getBoxID() {
return boxID;
}
public AppUser getOwner() {
return owner;
}
public ArrayList<AppUser> getReaders() {
return readers;
}
public Box(AppUser owner, String boxName) {
this.boxID = BoxUtils.getNextBoxId();
this.owner = owner;
this.boxName = boxName;
readers = new ArrayList<AppUser>();
readers.add(owner);
}
public void addReader(AppUser user) {
readers.add(user);
}
public String getBoxName() {
return boxName;
} // getBoxName;
}
The error is:
