Hello!

I need to generate an One-to-many relationship using the <map> tag

Here is the example hbm file which is working properly.

[code]<map name="itemResponses" lazy="true" table="response_items">
<key column="response_id"/>
<map-key column="map_key" type="string"/>
<element type="string" column="map_value" not-null="true"/>
</map>
[/code]

But it seems that i cannot find Xdoclet tags for doing this html from java code.

Am i missing something here? Or Xdoclet is incomplete?

Many thanks,

Florin Marcus

I guess you need combination of several XDoclet tags: map, collection-index, and collection-element
http://xdoclet.sourceforge.net/xdoclet/ ... map__0__1_
http://xdoclet.sourceforge.net/xdoclet/ ... dex__0__1_
http://xdoclet.sourceforge.net/xdoclet/ ... ent__0__1_

Did you solve the problem with map mapping using xDoclet ?
I use xDoclet 2 to generate <map> properties in hbm.xml. Here is the xdoclet tags usage:

* @hibernate.map
* cascade = "all"
*
* @hibernate.key
* column = "someParentIdInValueObject"
*
* @hibernate.map-key
* column = "someIdOfKeyObject"
* type = "com.my.KeyObjectClass"
*
* @hibernate.one-to-many
* class = "com.my.ValueObjectClass"

Here we have 'key' and 'value' objects in Map mapped to KeyObjectClass and ValueObjectClass repsectivly
The usage of Map is similar to other 'one-to-many' collections mapping, like set, list, etc.

I was able to generate correct mapping file, however had some problems with persisting newly created and pre-populated object with non-empty map property.

Hope this help
