Subject Network protocol error in prepareStatement()
Date Mon, 12 Nov 2007 04:39:20 GMT
Hi all.

I'm getting this unusual exception during prepareStatement():

Caused by: org.apache.derby.client.am.DisconnectException: A network protocol error was encountered
and the connection has been terminated: the requested command encountered an unarchitected
and implementation-specific condition for which there was no architected message

The connection is from the host to itself so network issues should hopefully
be out of the picture.  Any idea what causes this error?  The derby log is completely
empty this time (no error messages, no success messages either.)
