Hi All.
I want to write a finder that finds the parent objetc for a 1:1 relation. Wirth a
1:many relation, i can use the IN operator, but with a 1:1, I got no idea what to do.
My EntityBeans look like this:
TempData:
uuid: String
name: String
binaryData: BinaryData
tumbnailImage: BinaryData
previewImage: BinaryData
[...]
BinaryData:
uuid: String
name: String
[...]
When I try using a statement like
@ejb.finder
signature = "TempDatenLocal findTempDataByBinaryData(java.lang.String binaryDataId)"
query="
SELECT OBJECT(a)
FROM TempData AS a, IN(a.binaryData) AS b
WHERE (b.uuid = ?1)
"
I get this:
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'SELECT
OBJECT(a) FROM TempData as a, in(a.binaryD
ata) as b WHERE (a.uuid = ?1)'; - nested throwable:
(org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "a.binaryData" at line 1,
column 44.
Was expecting:
<COLLECTION_VALUED_PATH> ...
)
Any Idea, how I can make this finder work???
Thanks in advance,
Sascha.
