Thanks! Derby Version is (from Manifest):
Bundle-Name: Apache Derby 10.5
Bundle-Version: 10.5.3000000.802917
I have made a few changes and this is where things stand now.
Domain Object (CastMember) as follows :
byte[] headShot
static constraints = {
headShot(nullable: true , maxSize:2097152 )
}
static mapping = {
id generator:'identity'
headShot type: 'blob'
}
I checked the table in the database and the column HEAD_SHOT is BLOB.
In my controller I am doing the following.
while( itr.hasNext() ) {
MultipartFile file = request.getFile( itr.next() )
byte[] myBytes = file.getBytes()
def castMember = CastMember.findById(params.characterID)
castMember.headShot = Hibernate.createBlob(myBytes)
validateAndSave ( castMember )
}
The new stacktrace is this,
Hi,
I'm sorry, this stack trace doesn't make any sense to me, as I'm not
familiar with Groovy.
However, to me it looks like the problem lies outside of the database,
possibly with the Hibernate mapping?
Why should the Blob object be cast to a number?
Maybe a Groovy/Grails or Hibernate forum/list would be able to give you
a better answer?
Regards,

Thanks for responding but the problem is that I am trying to insert an

Any other ideas? BTW: How can I verify what version of derby is running?
My

Hi Doug,
Can you post the stack trace from the exception?
Are you sure Hibernate is mapping the column to the right column type?
Regarding the Derby version, one way to figure it out is invoke the
command below with at least one of the Derby jars (i.e. derby.jar,
derbyclient.jar etc) in the classpath:
java -cp<yourclasspath> org.apache.derby.tools.sysinfo
or potentially
java -jar derbyrun.jar sysinfo
I don't remember exactly, but I think you can use JDBC meta data calls
as well. You can also look at some files inside one of the jars, for
instance the manifest file, and if you start ij the version is printed
(not the full version, i.e. only 10.5).
Regards,

Hi Doug,
I think this error means you're trying to insert a string that's longer
than 255 characters into a VARCHAR(255) column. Derby will try to
truncate the string if it has trailing spaces, but the above exception
will be thrown if that's not enough to make it fit in the column.
In Derby 10.5 and later, the error message should show the string you're
trying to insert instead of the rather cryptic string 'XX-RESOLVE-XX'.
(The error message was changed in DERBY-961.)
