here is the code of the getter and setter methods

public String getUuid() {
    return uuid;
}

public void setUuid(String uuid) {
    this.uuid = uuid;
}

and the mapping portion is

<id name="uuid" type="java.lang.String">
    <column name="UUID" />
    <generator class="uuid"/>
</id>

i am new to hibernate so not much idea what exactly is the problem my destination class has refrence to few other class which are also getting persist when i am persisting Destination class

any help in this regard is much appricitaed

Edit1

Well the problem seems to be with respect to the relation i have defined in the Destination class as well in the mapping file..

private Set<PlaceToVisit> placesToVisit=new HashSet<PlaceToVisit>();

public Set<PlaceToVisit> getPlacesToVisit() {
    return placesToVisit;
}

public void setPlacesToVisit(Set<PlaceToVisit> placesToVisit) {
    this.placesToVisit = placesToVisit;
}

public void addPlaceToVisit(PlaceToVisit placeToVisit){
    placeToVisit.setDestination(this);
    this.placesToVisit.add(placeToVisit);
}

as well in mapping file as

<set name="placesToVisit" table="PLACETOVISIT" inverse="false" lazy="true" cascade="save-update">
    <key>
        <column name="DESTINATIONID" />
    </key>
    <one-to-many class="PlaceToVisit" />
</set>

while i have following in the PlaceToVisit class

<id name="uuid" type="java.lang.String">
    <column name="UUID" />
    <generator class="uuid"/>
</id>

<property name="name" type="java.lang.String">
    <column name="NAME" />
</property>

<many-to-one name="destination" class="Destination" fetch="join">
    <column name="DESTINATION" />
</many-to-one>

and other getter setter for this class

when i am removing all refrences of the associations from the destination class everything working fine but adding any relation entry in Destination mapping file showing me the above described error.

Answer 1

This error may be caused by the fact that the object of some other type was found where the object of type Destination was expected.

For example, if some other class was accidentially added to Collection<Destination> via unchecked cast.
