Develop a serializable exception, have all your application
exceptions extend that and then when you get one you can serialize it
down the URLConnection's stream.

No. It's not really meant for that purpose. It could be used though.
Encode the error as a String header field (ie: exception.toString())
and when you get an error response to some HTTP request use:
throw Class.forName(
URLConnection.getHeaderField("error-header-name") ).newInstance();
That will throw an exception with the same name as the one you have
in the header named:
"error-header-name"
