First, Axis2 One Way _does_ throw exceptions in its current state: http://issues.apache.org/jira/browse/AXIS2-304
Basically I get a socket timeout on long requests. AFAIK, there are two types of in-only. Robust in-only - which I believe is the current implementation - and fire-and-forget - the latter AFAIK yet to be implemented in axis2. Furthermore, I have seen the 'server is not available, yet no exception' issue in the current robust-only implementation. I haven't read the spec entirely, but .net behavior may indicate that there should be compatibilty. My suggestion is to verify that the wsdl 2.0 spec does indeed indicate that robust in-only should throw when the server is down - that seems to be what you want. If so and there are no further comments, I suggest filing a JIRA. HTH, iksrazal Em Sábado 17 Dezembro 2005 15:15, o Peter McEvoy escreveu: > Hmmm. This does not seem very satsifactory.
