Hi,

1)

I want to persist an class array. Hibernate wants an @IndexColum annotation.
How can I prevent this, I dont care about the order of the elements.

2) I want to persist boolean [] and String[]. It seems that hibernate stores this a blob with java serialization. How can I achive a custom format (CSV, XML, ...)?

Thx.

if you don't care about ordering, don't use an array. There are bettern unordered containers in java

Hi,

thanx for your reply!

Yes, I could use a Set, but the problem is, that the Entity belongs to an API which must be still compatible with Java 1.4 and must be strongly typed. So I cannot use Set/Collection etc.
Ok I will think about a wrapper in the DAO layer or @PostLoad/PrePersist methods.

Have you an idea about point 2) too?

you'd better use @CollectionOfElements and let the propary types be stored in a specific association table

Hm, I think I forgot to say, that I want to use only JPA annotations.
Is it possible to configure this anywhere in xml?
