I get this error with the following xml:

<primitive-array name="props">
<list-index column="sortIndex"/>
</primitive-array>

org.hibernate.MappingException: invalid mapping
The content of element type "primitive-array" must match "(meta*,subselect?,cache?,synchronize*,comment?,key,(index|list-index),element,loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?)".

** props is the name of my property defined as: double[] props - in my class

** I picked an arbitray name for the index column. I'm not sure how to get the index column of the property table.

Can someone tell me what I should be doing to map this class property array?

the Java type of a property holding a collection must be the interface type (ie. Map, Set or List; never HashMap, TreeSet or ArrayList). This restriction exists because, when you're not looking, Hibernate sneakily replaces your instances of Map, Set and List with instances of its own persistent implementations of Map, Set or List

does this mean I can't use double[][] as a datatype for a persistent property or does it mean that Hibernate will convert the double[][] to Array?

This is very confusing and I can't find anything in the documentation abot it!

Regarding your exception, did you read the message? key, index|list-index, and element are all required. What is "Array"? Hibernate handles arrays as arrays as far as I know. It can't and doesn't do anything unusual with them. I'd recommend staying away from them, though, since you won't get the optimizations available from using a Collection type. I'm not sure if/how Hibernate handles nested arrays, though.

hi!

it is very interesting for me: have you solved this problem or not?
I have a similar problem. I have a class and such a field in it:

public double[] arrOfDoubles;

getter;
setter;

I use xdoclet for hibernate mapping. I tried to use a lot of variants of tags description, but nothing helps.
For example:
/**
* @hibernate.primitive-array table="doubles" cascade="all"
* @hibernate.collection-key column="parentId"
* @hibernate.collection-element column="value" type="double"
* @hibernate.collection-index column="id"
* @hibernate.collection-one-to-many
* @return
*/
Where is the same exception in any way:

[hibernatedoclet] org.xml.sax.SAXParseException: The content of element type "primitive-array" must match "(meta*,subsel
ect?,cache?,synchronize*,key,(index|list-index),element,loader?,sql-insert?,sql-update?,sql-delete?,sql-delete-all?)".

What do I do wrong? Can anybody help me?
Thanks in advance.

I am new in this forum, I could get the type of error. the problem were the order of tags in *.hbm.xml configuration file
