Hi all,
Forgive me if this is answered elsewhere but I haven't found anything yet.

I have an object called House, house will have a HashMap of
descriptions.

The descriptions will be accessed with a locale object.

ie

Map map = house.getDescriptions();
System.out.println(map.get(Locale.EN));

Here comes the confusion.

1)There doesn't seem to be many examples of using a HashMap
to be found on the web.

2) Is this the way to do something like this or do I need to go using
a usertype.

3) Am I barking up completely the wrong tree. Is there
another way that people usually do this ?

4) Anyone got a bit of sample code that does something like this
using xdoclet for hibernate mapping file generation ?

5) I want to add a helper method to the class so I can do this.

System.out.println(house.getLocalizedDescription(Locale.FR,Locale.EN));

here is what I was thinking of doing to the House class

public String getLocalizedDescription(Locale locale, Locale default) {

a_ check to see if there is anything in the HashMap that matches the
locale specified.

b_ If there is then return it.

c_ If there isn't try the default.

d_ If there is anything there return it.

e_ See if there is anything there if so then return it.

f_ If all else fails return an empty string.

}

Is this a stupid idea ?

Ok maybe I'm a crazy optomist but pehaps all I need to do is this ,

/**
* @return Returns the descriptions.
* @hibernate.map cascade = "delete"
*/
public Map getDescriptions() {
return descriptions;
}

Am I living in dreamworld here ?

I don't know about the xdoclet definitions, but I would think youd need more than that (like the index and the key at least).

Check out http://www.hibernate.org/hib_docs/reference/en/html/collections.html#collections-mapping

This works fine, I am posting this in case anyone has the same problem.

/**
* @return Returns the summaryDescriptions.
* @hibernate.map cascade = "delete" table = "SUMMARY_DESCRIPTIONS"
* @hibernate.collection-key column="parent_id"
* @hibernate.collection-index type = "java.util.Locale" column = "LOCALE"
* @hibernate.collection-element type = "java.lang.String" column = "TEXT"
*
*/
public Map getSummaryDescriptions() {
return summaryDescriptions;
}
