SOAP WEB SERVICE - javax.xml.ws.WebServiceException: class com.developer.jaxws.Update do not have a property of the name devdesc

I am wondering why I am getting this error in my soap web server. where could I insert the property needed to properly deploy it. I have tried creating new web service and recreate the operations but the same error persist. I also tried removing and reinstalling glassfish server. where could I find it? I am using Netbeans 8.0.2 with glassfish 4.0. Thanks
