Hi All
Has anyone had any success writing blobs to an Oracle DB under WO 5.4?
I have a large project that makes extensive use of blobs and works fine
under WO 5.3 but throws the following error when writing a blob under WO
5.4:
com.webobjects.eoaccess.EOGeneralAdaptorException: Unsupported feature
(See full dump below.)
The code can read existing blobs from an Oracle DB without any problems.
It¹s just writing that causes exceptions.
To eliminate other factors, I created a test project with a simple version
of the offending code. It uses a table BlobTable with just a primary
key and a blob field. The code attempting the write is below. It gets text
data from a form via a key called notes¹. (The BlobTable already contains
one record.)
NSArray blobs =
EOUtilities.objectsForEntityNamed(session().defaultEditingContext(),
"BlobTable");
if ((blobs != null) && (blobs.count() > 0)) {
BlobTable blob = (BlobTable)blobs.objectAtIndex(0);
NSData blobData = new NSData(notes(), "UTF8");
blob.setBlobData(blobData);
session().defaultEditingContext().saveChanges();
}
The problem is occurring on an OS X Leopard box in either Xcode or Eclipse
(not that that should matter). The JDBC driver is for Oracle 9i 9.2.0.8
it¹s a file called ojdbc14.jar.
If anyone has Oracle blobs working under 10.4, that would be great news
I¹d would then know to dig deeper rather than file a bug report.
Better still how did you do it?
Thanks
