If you are using hibernate you can use @Fetch annotation with FetchMode.JOIN. This will make hibernate use join and fetch collection with a single select query joining your element collection table. Make sure your collection has two annotations:

@ElementCollection(fetch=FetchType.EAGER)
@Fetch(FetchMode.JOIN)
