Hi forum,

Hi have some problem with hibernate.
I use MyEclipse 3.8.4 on linux gentoo with sun jdk 1.4.2

When I try to load my class I get a castClassException:
02/21 11:13:15 error
[1]java.lang.ClassCastException
at net.sf.hibernate.type.IntegerType.set(IntegerType.java:34)
at net.sf.hibernate.type.NullableType.nullSafeSet(NullableType.java:48)
…
…

I have two table:
UserComunity
UserProfile

With a one-to-one relation
I think there are some problem in hbm.xml generate by MyEclipse but I don’t uderstand what.

my xml:
<?xml version=”1.0″?>

Lorenzo,
Do all the “type” fields that MyEclipse generated match up to the Java Types you have defined for the methods in your classes?

Also, what is the entire exception? What line does it point to in YOUR code?

the code line problem is:
UserProfile profile = (UserProfile) hSession.load(UserProfile.class,usr);

When Hibernate load UserProfile I get cast exception.
May be some problem about UserComunity id and foreign key of UserProfile.

I chech UserProfile and UserComunity class and all type match.
Many thanks in advance

regards Lorenzo

my snippets:
try {
hSession = SessionFactory.currentSession();
UserComunity usr = (UserComunity) hSession.load(UserComunity.class,userComunityForm.getId_user());
UserProfile profile = (UserProfile) hSession.load(UserProfile.class,usr);
/*logger.info(new Date()+ userComunityForm.getAdress() );
profile.setAddress(userComunityForm.getAdress());
*/
pack.addParam(“update”,”1″);
hSession.flush();
SessionFactory.closeSession();

} catch (HibernateException e) {
e.printStackTrace();
}

my exeception:

UserComunity usr = (UserComunity) hSession.load(UserComunity.class,userComunityForm.getId_user());
UserProfile profile = (UserProfile) hSession.load(UserProfile.class,usr);

You don’t want to pass ‘usr’ to the load method, you need to pass the PK of UserProfile so Hibernate can load it… how is it suppose to know which method on UserCommunity will return the PK?

Try this:
```
 UserComunity usr = (UserComunity) hSession.load(UserComunity.class,userComunityForm.getId_user());
UserProfile profile = (UserProfile) hSession.load(UserProfile.class,usr.getProfileID()); 
```
Where “getProfileID()” is whatever method you wrote to get the UserProfile ID from the UserCommunity object.

May be there are some problem in my db structure and Hibernate.
my table:

UserComunity:
-id_user
-email
-pswd
-…

UserProfile
-id_user_fk -> UserComunity.id_user
-fullname
-adress
-city
-….

from Hibernare log I get:
expected type: it.kemen.standard.hibernate.UserComunity, actual value: java.lang.Integer

Please post information on what database you are using (version too), and also supply the DDL for the UserCommunity and UserProfile tables.

Nevermind. This is a bug, or at least a rare edge-case not accounted for in the current implementation. Basically, you have a one-to-one relationship here. However, it is the “primary key” variety of 1:1, i.e. each class has its own PK, but there is a FK constraint defined on one of the PKs that refers to the PK of the other table. I recommend you check out “Hibernate In Action” by Christian Bauer and Gavin King – it has a great section on this stuff. Also, look at http://www.hibernate.org/hib_docs/reference/en/html/mapping.html#mapping-declaration-onetoone for more.

Do you have any control over the table definitions in your database? If so, I think the FK style 1:1 would work for you. Basically, add another column to UserProfile that is a *unique* FK to UserComunity (and drop the FK on the id_user_fk PK). If you do not have this kind of power, you need to alter the mapping file definition as discussed at the above url (basically, add one-to-ones in both mappings plus a param element to the id).

first, tks for the answer.
I can modify my table but I prefer to keep my DDL because other application use it.
Anyway I try to add one-to-one relation in UserProfile xml like this:
<one-to-one name=”userComunity” class=”UserComunity” constrained=”true”/>

I get the same exception:

I don’t understand if it’s a bug of Hibernate or of MyEclipse wizard. In the first case I send a message to Hibernate Forum.

Many thanks for the suggestione about “Hibernate in Action”. It’s planned. 😉

Did you also add the 1:1 in UserComunity:

<one-to-one name=”userProfile” class=”UserProfile=”/>

as well as the special id generator and param in UserProfile:

<id name=”idUser” column=”id_user_fk”>
<generator class=”foreign”>
<param name=”property”>userComunity</param>
</generator>
</id>
…
<one-to-one name=”userComunity”
class=”UserComunity”
constrained=”true”/>

Note that the generator ‘foreign’ is special and important in your scenario, and that the param element with attribute value ‘property’ and body userComunity is also very significant.

This is not a bug in Hibernate; Hibernate will handle your DDL. The problem is that this is a use case not covered in the MyEclipse tool. But you should be able to tweak the generated mapping to get it to work…it might just take a lot of playing around.

</class>

</hibernate-mapping>

I think that the problem is <one-to-one name=”userProfile” class=”UserProfile=”/> because in UserComunity I don’t have userProfile reference.
Anyway if I remove one-to-one relation in UserComunity I get another exception:
– Mapping class: it.kemen.standard.hibernate.UserProfile -> user_profile
– Could not compile the mapping document

Um, I think it is just a typo, Lorenzo:

– Mapping resource: it/kemen/standard/hibernate/UserComunity.hbm.xml
– Mapping class: it.kemen.standard.hibernate.UserComunity -> user_comunity
– Could not compile the mapping document
net.sf.hibernate.MappingException: Could not find class: UserProfile=

and

<one-to-one name=”userProfile” class=”UserProfile=”/>

Note the equals sign at the end of UserProfile? Drop that.

I think that the problem is <one-to-one name=”userProfile” class=”UserProfile=”/> because in UserComunity I don’t have userProfile reference.

But you do; it is the one-to-one. Not sure what you are saying there.

I fix the typo and I add one-to-one relation in UserComunity:

Lorenzo –

You gotta read the exception starting from the top!

net.sf.hibernate.PropertyNotFoundException: Could not find a getter for userProfile in class it.kemen.standard.hibernate.UserComunity

So, do you have get/setUserProfile accessors on your UserComunity class?

in my UserComunity class I don’t have get/set UserProfile because in my table I don’t have any foreign key to UserProfile table.
In my UserProfile table I have a foreign key to UserComunity.id_user
In my post there are more test if you check.
I change UserComunity xml to fit the DDL

Anyway I post my ddl and xml to Hibernate forum may be some one can help me to fix my Hibertate xml.

many thanks

Lorenzo
