[/WEB-INF/applicationContext-dao.xml]: Invocation of init method

[Heather]

I have two related tables:

CREATE TABLE `nuser` (
`notification_id` bigint(20) NOT NULL,
`nuser_id` varchar(255) NOT NULL,
`nuser_startdate` timestamp NOT NULL default CURRENT_TIMESTAMP on
update CURRENT_TIMESTAMP,
`nuser_enddate` timestamp NOT NULL default '0000-00-00 00:00:00',
`nuser_isprivate` bit(1) NOT NULL,
`nuser_isowner` bit(1) NOT NULL,
`nuser_state` varchar(255) NOT NULL default 'nv',
PRIMARY KEY (`notification_id`,`nuser_id`),
KEY `notification_id` (`notification_id`),
KEY `nuser_id` (`nuser_id`),
CONSTRAINT `nuser_ibfk_1` FOREIGN KEY (`notification_id`) REFERENCES
`notification` (`notification_id`) ON DELETE CASCADE ON UPDATE CASCADE
)

CREATE TABLE `nuseractions` (
`nuseractions_id` bigint(20) NOT NULL auto_increment,
`notification_id` bigint(20) NOT NULL,
`nuser_id` varchar(255) NOT NULL,
`nuseractions_state` varchar(255) NOT NULL,
`nuseractions_date` timestamp NOT NULL default CURRENT_TIMESTAMP on
update CURRENT_TIMESTAMP,
PRIMARY KEY (`nuseractions_id`),
KEY `notification_id` (`notification_id`),
KEY `nuser_id` (`nuser_id`),
CONSTRAINT `nuseractions_fk` FOREIGN KEY (`notification_id`)
REFERENCES `nuser` (`notification_id`) ON DELETE CASCADE ON UPDATE
CASCADE,
CONSTRAINT `nuseractions_ibfk_2` FOREIGN KEY (`nuser_id`) REFERENCES
`nuser` (`nuser_id`) ON DELETE CASCADE ON UPDATE CASCADE
)

Then I do their xml:
First table

<composite-id name="id" class="com.bs.proteo.notifications.bl.beans.NuserId">
<key-property name="notificationId" type="long">
<column name="notification_id" />
</key-property>
<key-property name="nuserId" type="string">
<column name="nuser_id" />
</key-property>
</composite-id>
<many-to-one name="notification"
class="com.bs.proteo.notifications.bl.beans.Notification"
update="false" insert="false" fetch="select">
<column name="notification_id" not-null="true">
<comment></comment>
</column>
</many-to-one>
<property name="nuserStartdate" type="timestamp">
<column name="nuser_startdate" length="19" not-null="true">
<comment></comment>
</column>
</property>
<property name="nuserEnddate" type="timestamp">
<column name="nuser_enddate" length="19" not-null="true">
<comment></comment>
</column>
</property>
<property name="nuserIsprivate" type="serializable">
<column name="nuser_isprivate" not-null="true">
<comment></comment>
</column>
</property>
<property name="nuserIsowner" type="serializable">
<column name="nuser_isowner" not-null="true">
<comment></comment>
</column>
</property>
<property name="nuserState" type="string">
<column name="nuser_state" not-null="true">
<comment></comment>
</column>
</property>

<map name="nuseractionsesForNotificationId" inverse="true">
<key>
<column name="notification_id" not-null="true"/>
</key>
<map-key type="long" column="notification_id"/>
<one-to-many
class="com.bs.proteo.notifications.bl.beans.Nuseractions" />
</map>
<map name="nuseractionsesForNuserId" inverse="true">
<key>
<column name="nuser_id" not-null="true"/>
</key>
<map-key type="long" column="nuser_id"/>
<one-to-many
class="com.bs.proteo.notifications.bl.beans.Nuseractions" />
</map>

Second table

<comment></comment>
<id name="nuseractionsId" type="long">
<column name="nuseractions_id" />
<generator class="assigned" />
</id>
<!-- many-to-one name="notification"
class="com.bs.proteo.notifications.bl.beans.Notification"
fetch="select">
<column name="notification_id" not-null="true">
<comment></comment>
</column>
</many-to-one>
<many-to-one name="nuser"
class="com.bs.proteo.notifications.bl.beans.Nuser" fetch="select">
<column name="nuser_id" not-null="true">
<comment></comment>
</column>
</many-to-one -->
<property name="nuseractionsState" type="string">
<column name="nuseractions_state" not-null="true">
<comment></comment>
</column>
</property>
<property name="nuseractionsDate" type="timestamp">
<column name="nuseractions_date" length="19" not-null="true">
<comment></comment>
</column>
</property>

It works fine, all is defined and valid, but when the beans is configured appears this error:

[/WEB-INF/applicationContext-dao.xml]: Invocation of init method
failed; nested exception is org.hibernate.MappingException: Foreign
key (FK93DEA1A49CE1EDAC:nuseractions [notification_id])) must have
same number of columns as the referenced primary key (nuser
[notification_id,nuser_id])

Your problem isn't Hibernate, but the definition of the tables:
Check this:
Here, you define the primary key of the nuser and it is 2 columns

notification_id and nuser_id

 CREATE TABLE `nuser` (
  [...]

   PRIMARY KEY  (`notification_id`,`nuser_id`),

 )

But, here you tell it, to does a reference to a nuser table, only with the column notification_id

 CREATE TABLE `nuseractions` (

   CONSTRAINT `nuseractions_fk` FOREIGN KEY (`notification_id`)
 REFERENCES `nuser` (`notification_id`) ON DELETE CASCADE ON UPDATE CASCADE,

But nuser has a primary key with 2 columns, so it's incorrect.
check it, and fix it

The problem is your second mapping, you have a relationship many-to-one with "user" but you define a tag "column" when actually must define 2 of the user (you defined a composite-id for this object with 2 columns)

Good luck
