hibernate many-to-many
Hej..Jeg kan ikke få hibernate til at mappe ud fra XDoclet genereret hbm.xml
Jeg har et ganske simpelt opsæt..
3 tabeller
Account
KEY
USERNAME
PASSWORD
Group
KEY
NAME
Group-Account
GROUP_KEY
ACCOUNT_KEY
Jeg skal nu have lavet en many-to-many relation, så en Account kan ligge i flere Groups gennem Group-Account tabellen.
Min Account XDoclet mapping ser således ud:
/**
* @hibernate.set role="groups" table="ACCOUNT_GROUP"
* cascade="all" readonly="true"
* @hibernate.collection-key column="ACCOUNT_KEY"
* @hibernate.collection-many-to-many
* class="dk.videone.voware.hibernate.Group" column="GROUP_KEY"
* @return java.util.Set
*
*/
public List getGroups() {
return groups;
}
Når jeg har genereret gennem XDoclet ser min mapping i Account.hbm.xml således ud:
<set
role="groups"
table="ACCOUNT_GROUP"
lazy="false"
readonly="true"
cascade="all"
sort="unsorted"
>
<key
column="ACCOUNT_KEY"
>
</key>
<many-to-many
class="dk.videone.voware.hibernate.Group"
column="GROUP_KEY"
outer-join="auto"
/>
</set>
men i det jeg prøvet at lægge nogle grupper i Account
setGroups(groups);
fra min facade kommer en masse Exceptions.
det virker som om dk/videone/voware/hibernate/Account.hbm.xml ikke
findes men..... den er der
her er en stack trace:
