Hola all.
I have the following problem.
I have bidirectional, one to many relation (Team and Players)
I have a session facade bean contains the following methods :
public Collection getTeamPlayers(String name) {
Collection players = null;
try {
LocalTeam team = teamHome.findByPrimaryKey(name);
players = team.getPlayers();
this.convertCollection(players);
} catch (FinderException e) {
System.err.println("Error in getTeamPlayers(): " + e.toString( ));
}
return players;
}
private Collection convertCollection(Collection col) {
Iterator it = col.iterator();
Vector vec = new Vector(1);
while (it.hasNext()) {
PlayerDTO dto = this.extract((LocalPlayer)it.next());
vec.addElement(dto);
}
return vec;
}
private PlayerDTO extract(LocalPlayer player) {
PlayerDTO dto = null;
try {
dto = new PlayerDTO(player.getNum(), player.getName());
} catch (Exception e) {
System.err.println("Error in extract( ): " + e.toString( ));
}
return dto;
}
I have create a team with some players and set the CMR field (correctly, coz
I didn't get any exception, and the database contains the right values).
when invoking :
Collection col = manager.getTeamPlayers("FC Barcelona");
I got :
java.lang.reflect.UndeclaredThrowableException
caused by :
java.io.NotSerializableException : org.jboss.ejb.plugins.cmp.jdbc.bridge.Relationset
any help will be great.
