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.
