[Gionata Gelati <ge...@sparc20.ing.unimo.it>]

Hi,
  yesterday I was deploying my sercei, I tested it and everything was
fine. Changed port to tomcat for internal reasons, got the wsdl fiule of
my webservice, got the client stubs using the WSDL2Java
emitter. problem: i can bind to the service, but when the object providing
the service is not instatiated and when the client gets to call the remote
method of the service I get the following:

WrapperClient: trying to bind...
WrapperClient: binded!!
