Hi Folks I am trying to resolve a problem a few days and I am stuck here. I am relatively new to webservices and trying to figure out what is the problem. I am using JBoss 4.0.5 GA which has bundled JBossWS 1.4. When I run a webservice client I get an error. Note: I have used "+++" to seperate peices of Source Code
Will appreciate if some one could point me to the problem. I am assuming that there is a problem is with some mapping file ,because I am able to invoke the sayHello method via the second method . Also I read same kind of problem faced by another person,but had no reply posted http://lists.jboss.org/pipermail/jbossws-users/2007-January/001196.html Note - I picked up the server code from example stated in the URL below http://www.soapui.org/jbossws/topdown_example.html Thanks a ton in advance +++++++++++++++++++++++++++++++++++ ERROR +++++++++++++++++++++++++++++++++++ Contacting webservice at http://localhost:8080/HelloWorld output:Hello How are you, Kapilesh!
