Subject [jira] Commented: (OPENJPA-922) setByteArrayInputStream being used in stead of setBytes
Date Tue, 24 Feb 2009 20:31:01 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12676403#action_12676403
] 

B.J. Reed commented on OPENJPA-922:
-----------------------------------

Was premature with the patch.  The "fix" breaks BLOBs so it's no good.  Basically, both unserialized
BLOBS and byte arrays go through the ByteArrayValueHandler in stead of the BlobValueHandler
(determined in MappingHandler.defaultHandler()) so the jdbc layer doesn't know there is a
difference between the 2 and can't make the correct call to set the data....the use of ByteArrayValueHandler
for both also happened on Derby so we need a way to differentiate between the two different
kinds of byte[] (BLOBs and char for bit data) so that we know which method to use to set the
data in the DB.

> I have an Entity and one of its fields is defined as CHAR(16) FOR BIT DATA NOT NULL.
> When trying to persist the entity, I get the following error:
>    Error: SQLCODE=-301, SQLSTATE=07006, SQLERRMC=1, DRIVER=3.50.152  
>    {prepstmnt 1386959531 INSERT INTO NULLID.TESTTBL (tkiid) VALUES (?)  
>    [params=(InputStream) java.io.ByteArrayInputStream@75947594]}
> It seems that the wrong kind of set is being used to set the parameter on the prepared
statement.
