Hi Everybody,

I have two problems recreating my mapping in xDoclet.

The first:

I

I'm not sure what your problem is. The mapping looks fine.

Hi Gavin,

btw: XDoclet: 1.2b4

Thanks for the reply, I'll try and elaborate.
The mapping I've done by hand and it works really well.
Now I'm implementing xDoclet to create my mapping files as the project is growing fast and it's becoming dificult to maintain one global mapping file.

I can't recreate my "by-hand" mapping using xDoclet.

Here are my two java classes, I want the created hbm to be the same as the excerpt in the first part of my message.

Full Listing of Composite ID class
----------------------------------------------------
package com.xxx.model.xData.text;

* NOT PERSISTED AS A FIRST RANK CLASS

this.key = key;

public boolean equals(Object o) {

final TextId textId = (TextId) o;

if (!key.equals(textId.key))
return false;
if (!locale.equals(textId.locale))
return false;

return true;

public int hashCode() {
int result;
result = key.hashCode();
result = 29 * result + locale.hashCode();
return result;
}
}

Part of "main" class that has a map of Composite Id's and String objects
----------------------------------------------------

private Map names; //initialised in the constructor

/**
* ---No hibernate mapping, this is done by an include at the moment---
* @hibernate.map
* table="ik_Text_Instance"
* @hibernate.collection-key
* column="ik_objectId"

* type="string"
* column="ik_Text"
*/
public Map getNames() {
return names;
}

public void setNames(Map names) {
this.names = names;
}

-------------------------------------------------
I feel that I ought to be using @hibernate.key-properties and @hibernate.composite-index javadoc tags, but I can't find any doco on these apart from the odd message on the development mailing list that these may or may not be implemented (dated Dec 2002)
--------------------------------------------------

Generated file as follows:

--------------------------------
<map
name="names"
table="ik_Text_Instance"
lazy="false"
sort="unsorted"
inverse="false"
cascade="none"
>

<key
column="ik_objectId"
/>

<index
column=""
/>

<element
column="ik_Text"
type="string"
not-null="false"
unique="false"
/>

</map>

Is the solution to continue to use a "merge" document?

Thanks,

Dan

ah, I'm not sure of the XDoclet module supports composite-index ... you might need to use a merge file for this.

Hi Gavin,

Ok Fine.

It seems that xDoclet doesn't support:

<composite-index>

or

<any>

But it seems easily solved with the use of a "merge" document.

Thanks,

Dan

Hello

I am a newbie with Hibernate and I wanted to use the "composite-index" with xdoclet.
I have finally managed to use it although the "composite-index" tag is not mentionned by the xdoclet list :

http://xdoclet.sourceforge.net/xdoclet/ ... -tags.html

But as it is said there : http://opensource.atlassian.com/project ... se/XDT-830

Xdoclet now supports this tag :

@hibernate.collection-composite-index
class="NameOfClass"

Here is my example :

I use a Map which contains customized "Preference" objects and the key is a "PreferencesKey" object with 2 properties : the string "language" and a integer "key_id" managed by myself (it is the simplest way I have found to have a list of "Preference" objets in my Map without using nested collections that are not supported by Hibernate).

Now, the xdoclet tags with "composite-index" are :

/**
* @hibernate.map
* table="XXXXXXXXX"
* lazy="true"
* cascade="all"
* @hibernate.collection-key
* column="my_object_id"
* @hibernate.collection-composite-index
* class="XXXXX.PreferencesKey"
* @hibernate.collection-many-to-many
* class="XXXXX.Preference"
* column="preference_id"
*/

I also have to describe the PreferencesKey class:

/**
* id manipulation
* @hibernate.property
* column="key_id"
*/
public int getId(){
return this.id;
}

public void setId(int id){
this.id = id;
}

/**
* langue manipulation
* @hibernate.property
* column="language"
*/
public String getLangue(){
return this.langue;
}

public void setLangue(String langue){
this.langue = langue;
}

And it works : xdoclet generates the right hbm.xml file :

[...]
<map
name="preferencesMap"
table="XXXXXXXXXX"
lazy="true"
sort="unsorted"
cascade="all">

<key column="my_object_id">
</key>

<composite-index
class="XXXX.PreferencesKey">
<key-property
name="id"
type="int"
column="key_id"/>

<key-property
name="langue"
type="java.lang.String"
column="language"/>

</composite-index>

HIbernate support has been recently improved with a focus on H3. Check out the CVS version (or the 1.3.x release once it is out).
