Hi there,
we tried to port our (working) service from 0.95 to 1.0, but encountered some
problems. After calling WSDL2Java once for the service and once for the client
(in the same manner as for 0.95) we ended up with a non-working client.
We also get a warning from log4j, is this something to be worried about?
log4j:WARN No appenders could be found for logger
(org.apache.axiom.om.impl.builder.StAXOMBuilder).
log4j:WARN Please initialize the log4j system properly.
The wsdl is attached. Our error message is below. We think it must be a
server-related problem, so it's probably due to the 1.0RC1 update.
Our service is called SVMHCService, with the method predictEpitopes.
Please let us know if you have similar problems porting your service or what we
can try to work around this.
Thanks for your time,
