Finder-Method for a 1:1 relation - IN operator doesn't work

[saschav]

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.

How is the relation a.binaryData defined? Please give me the definition of the getter and settter (XDoclet-tags).
