Sending Large Messages

[Jennifer Ruttan <je...@indivica.com>]

Hi,

I've written a web service client that sometimes sends large messages (base64-encoded file content). I'm able to construct the message OK, but the message fails to be written to the server.

Here's the relevant part of the stack trace:

I'm wondering whether this is a problem with me or the web service itself. Are there strategies for dealing with this kind of scenario? The message in question is about 7mb.

Thanks
Jen
