Hibernate 3.1:

Mapping documents: Annotations
@OneToMany(cascade={CascadeType.ALL}, fetch=FetchType.EAGER, mappedBy="basket")

@Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL, region="shopping")

public Set<BasketItem> getBasketItems() {

return this.basketItems;

}

public void setBasketItems(Set<BasketItem> items) {

this.basketItems = items;

}


Name and version of the database you are using: Oracle 10g

Is it normal behavior that when I delete an item in a collection that has been cached (both the entity and thought the parent) that it removes the entire collecion from cache. The next time I load this data it needs to select all the Items in the collection.

Below is the output from the second level cache when I delete.

DEBUG - org.jboss.cache.TreeCache - _remove(GlobalTransaction:<null>:22, "/scps_cache/shopping/edu.nyu.scps.website.domain.shopping.Basket.basketItems#36")


Is it possible to just remove the ID of the item in the collection relationship?

Thanks,
Josh

what second level cache provider are you using? what do the caching properties look like?

I am using Jboss TreeCache. In this cache you don't specify entity objects in the configuration file, you just configure cache regions.

I am not familiar with TreeCache, but I think that how the eviction happens is a property of the caching tool, not of Hibernate. Maybe post your question on the TreeCache forum or explore other caching tools?
