Creating a Blob

[Daniel Noll <da...@nuix.com.au>]

Hi all.

I have some large binary content of unknown length which I want to 
insert into our Derby database.  Our existing system does this by 
writing the content to a temporary location, determining its size and 
then using PreparedStatement's setInputStream method to pass it in.

However, it occurs to me that the Blob API gives me a way to access an 
OutputStream which can be written to in order to push the large binary 
data over to Derby.  Problem is, Blob is an interface with no [useful] 
public implementations, and JDBC expects that each driver will offer a 
different way to do this (if at all.)

Does Derby have a "secret" way to create a Blob object?

Daniel
