By the way, I am currenly using the following query;
String s = "SELECT x FROM AuthIdentifierSet x inner join x.backingSet
y WHERE y.value = 'niko'";
where in my java code I have:
public class AuthIdentifierSet {
@PersistentCollection(elementCascade=CascadeType.ALL)
private Collection<String> backingSet = new HashSet<String>();
...
}
and this is the error message I have:
[junit] <openjpa-1.1.0-SNAPSHOT-runknown nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: An error occurred
while parsing the query filter "SELECT x FROM AuthIdentifierSet x
inner join x.backingSet y WHERE y.value = 'niko'". Error message:
Attempt to query field "y.value" from non-entity class "null".
value in this case, is the private char array of the string class.
I tried a few other things, but that one seemed the closest from what I wanted.
Any ideas is welcome.
Niko,
