Hi,

I have this annotation mapping:

Code:

@oneToMany(mappedBy="category",cascade=CascadeType.ALL)
public Set<User> getUsers(){return users;}


But, when i try to remove the category i get the foreing key exception, Why Doesn't hibernate delete my relations when i try to delete this side of relationship? Could someone help me?

Hi,

Cascade type all is cascade all except delete-orphan. If you want that then you would need to use delete orphan option in cascade type.

Thanks,

But in CascadeType Enum doesn't have a delete-orphan, Where can i found this type? I know there is in xml configuration. I found a CascadeStyle from hibernate packages but i would like to use the javax.persistence... Is it possible?

Which version of hibernate are you using?

This one has it:
[url]
http://www.hibernate.org/hib_docs/annot ... eType.html
[/url]

javax.persistence can be considered a kind of sub-set of hibernate, it will not have all the features present in hibernate annotations.

If you switch to mapping xmls then you will be able to use more of hibernate functionality.

Jitendra

I tried to use this :



Code:

@OneToMany(mappedBy="departamento",cascade=CascadeType.ALL)      @Cascade(value={org.hibernate.annotations.CascadeType.DELETE_ORPHAN,org.hibernate.annotations.CascadeType.ALL})
public Set<Category> getCategorys();



But didn't work, Is that something wrong? Thanks for help me.

What is the error/exception?

Try putting only delete_orphan as option instead of both.
