java.io.NotSerializableException:
what does the above exception mean?
i have a fingerprint template which i placed in an Object and trying to save into a Blob in Oracle. but i get that error
this is what i did
bos =new ByteArrayOutputStream();
oos =new ObjectOutputStream(bos);
oos.writeObject(fprint);
pstmt = con.prepareStatement("UPDATE T_FINGERPRINT SET FINGERPRINT_THUMB=? WHERE BADGENUM ='" +badge+"'");
pstmt.setBytes(1,bos.toByteArray());
rowcount = pstmt.executeUpdate();
this method of course implements the Serializable interface andfprintis of type Object

Hi Mike
This class implements the Serializable interface
the Object is declared within the class as
private Object image=null;
in a method inside that class, a fingerprint template named fprint is put into the variable image as in fprint=image
and then saved as a blob in the database

That's been answered.

but not for the fprint object

yes
> the object is an image template
whatever that is
> maybe its not serializable?
I suggested that in reply #2. There's no 'maybe' about it, that's exactly what the exception is telling you.
