Hi,

Is it possible to add a persistent property to an entity that has a simple Map<String,String> type? I'm having trouble finding the JPA-compliant way to do it (I've seen an example in the hibernate tests package that should do it using hibernate-specific annotations).

Is there a way to keep the simple Map<String,String> field using standard annotations?
The types/tables are something like what appears below:

Code:

@Entity @Table("customers") Customer {

  @Id int id;

  String name;

  [b]Map<String, String> properties[/b];
}

TABLE CUSTOMERS
-------------
ID      NAME
1       "James"
2       "John"

TABLE CUSTOMER_PROPERTIES
-------------
CUST_ID      PROP_KEY              PROP_VALUE
1            "PREFERRED_CHEESE"    "CHEDDAR"
1            "PREFERRED_MILK"      "LOW FAT"
