Subject Re: Problem streaming large blobs from Jackrabbit
Date Thu, 23 Apr 2009 11:35:02 GMT

Hi Ian,

Thanks for the response:

We are storing the blobs in MySQL and we have not set the max packet size,
but as you you suggest, it seems to be aware of the blob size when it tries
to read back the data,

regards

Dave
