Hi i'm using Hibernate version:2.1.7 and xdoclet-hibernate-module-1.2.2.jar.... After running my Junit test it gives weird exception. Take note that i'm using the template made by the equinox tool (AppFuse). I don't understand why it's not working though... Please help.

Mapping documents:
User.java has:


/**
* @hibernate.list lazy="true" inverse="true" cascade="all"
* @hibernate.jcs-cache usage="read-write"
* @hibernate.collection-key column="fk_owner_id"
* @hibernate.collection-index column="many_index"
* @hibernate.collection-one-to-many class="com.ssip.onlinewar.common.valueobject.UserGroupVO"
* @return List
*/
public List getCreatedUserGroups() {
return createdUserGroups;
}

public void setCreatedUserGroups(List createdUserGroups) {
this.createdUserGroups = createdUserGroups;
}



and UserGroup has the following:

/** A business entity class representing user_group.
*
* @since 1.0
* @hibernate.class table="user_group"
*/
public class UserGroupVO extends ValueObject
{
private Long userGroupId = new Long("-1");
private Long ownerId = null;
private String groupName;
//public GroupMemberVO groupMembers[];

public UserGroupVO()
{

}

/**
* @hibernate.id column="user_group_id" generator-class="native" unsaved-value="-1"
* @return
*/
public Long getUserGroupId() {
return userGroupId;
}

public void setUserGroupId(Long userGroupId) {
this.userGroupId = userGroupId;
}

/**
* @hibernate.property column="group_name" type="string"
* @return
*/
public String getGroupName() {
return groupName;
}

public void setGroupName(String groupName) {
this.groupName = groupName;
}

}

Debug level Hibernate log excerpt:

Correction. The Equinox is using hibernate version 2.1.6 and I've been using different kinds of methods like array, Set and List for my one-to-many approach but still having the same problem. Please help me.

I just found out the solution to my problem... I just change my hibernate version to 2.0 and it works... then try to re-generate the hbm.xml files....
