I always serialize the object to a byte and then use setBinaryStream(), e.g.
byte b = ... // serialize arbitrary object to byte
ByteArrayInputStream ins = new ByteArrayInputStream(b);
ps.setBinaryStream(psParamIndex, ins, b.length);
I've found this to be reliable. FYI Problems with using setObject () with blobs is not
specific to Derby. I've had to use the above with MySQL and Oracle as well.

Would that work? Regards, Ali--- Mithun Ruikar <firstname.lastname@example.org> wrote:Hello there , I have problem while setting Blob value to table created in derby. I had created : a datasource by parameter create=true. and then created new table in it with one column with Datatype as Blob. But when I tried to setObject value to this column ( by serializable object awt.color) It gave derby exception : trying to get Blob value from Object type. setBlob also didnt work with error saying : this method is undefined for (int , Object) and if i typecast it to (int , (Blob) Object) : I got classcastexception. please tell me how to set this value to blob field -- mithun --------------------------------- Do you Yahoo!?
