Ich baue gerade einen Webservice mit dem Restlet-Framework. Der serverseitige Kram läuft auf einem Tomcat, die Clientseite ist eine JavaFX-App. Ziel soll es sein, ein Pack-/Ladelistenprogramm für ein Messebauunternehmen zu schaffen (deshalb auch das Denglisch, am Anfang ist das noch so, damit ich mit dem zuständigen Menschen kommunizieren kann).
Jetzt zum Problem: Ich habe die Anwendungen jetzt soweit, dass ich Baugruppen erstellen und verändern kann (Methoden @Get & @Put, Ergebnis wird in einer DB gespeichert), aber beim @Delete kann Restlet plötzlich das Baugruppe-Objekt, das ich dem Request mitschicke, nicht mehr deserialisieren. Irgendwie stehe ich gerade vor einer Wand und Google hat mich auch nicht weitergebracht, der Fehler, der bei den aufgelisteten Beiträgen behandelt wird, ist meistens die Verwendung eines falschen externen Serialisierers, den ich ja überhaupt nicht verwende. Die jars, die ich einbinde, sind org.restlet.jar, org.restlet.ext.servlet.jar (nur auf der Serverseite) und die jar mit den Domain-Objekten.
Hier mal mein Code:
POJO
public class Baugruppe implements Serializable
{
/**
*
*/
private static final long serialVersionUID = -742123795806681688L;
private int id;
private String name;
private String description;
private List<Baugruppe> subBaugruppen = new ArrayList<Baugruppe>();
private List<Bauteil> bauteile = new ArrayList<Bauteil>();
public Baugruppe()
{
this("Name");
}
public Baugruppe(String name)
{
this(name, "Beschreibung");
}
public Baugruppe(String name, String description)
{
setName(name);
setDescription(description);
}
public int getId()
{
return id;
}
public void setId(int id)
{
this.id = id;
}
public String getName()
{
return name;
}
public void setName(String name)
{
if (name.length() > 45)
{
IllegalArgumentException iae = new IllegalArgumentException("Name zu lang!");
throw(iae);
}
this.name = name;
}
public String getDescription()
{
return description;
}
public void setDescription(String description)
{
if (description.length() > 200)
{
IllegalArgumentException iae = new IllegalArgumentException("Beschreibung zu lang!");
throw(iae);
}
this.description = description;
}
public List<Baugruppe> getSubBaugruppen()
{
return subBaugruppen;
}
public void setSubBaugruppen(List<Baugruppe> list)
{
subBaugruppen = list;
}
public List<Bauteil> getBauteile()
{
return bauteile;
}
public void setBauteile(List<Bauteil> list)
{
bauteile = list;
}
}
Serviceinterface für den dynamischen Proxy:

public ArrayList<Baugruppe> getBaugruppen();

public void save(Baugruppe baugruppe);
@Delete

Also irgendwie ist mir das zuviel, bei den beiden anderen Methoden klappt alles und hier kann er auf einmal nicht mehr das Objekt deserialisieren? Wer weiss Rat?
