Boa noite!
Comecei a estudar WebService, inicialmente estou tentando entender seu funcionamento, porém me deparei com alguns problemas que não consegui solucionar, conforme descrito abaixo:
- Estou utilizando o JBoss 4.2.2.GA.
Impementei um WebService HeloWorld conforme código abaixo:
[code]package com.tcc.controlefinanceiro.model.ws;
import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
@Stateless
@WebService(targetNamespace = “HelloService”)
public class Hello{
private String message = "Hello, ";
public Hello(){
}
@WebMethod
public String sayHello() {
return message;
}
}
[/code]
Bom, disponibilizei o serviço e OK, acesso o WSDL utilizando o browser, por exemplo http://localhost:8080/tcc-controlefinanceiro-model/Hello?wsdl. Segundo o que eu li, se eu acessar o WSDL via http, pelo browser é porque o serviço foi disponibilizado com sucesso.
Agora caberia a quem deseja acessar este serviço desenvolver um client que faça este meio de campo, correto? Para isso comecei a estudar o AXIS. Fiz um client para acessar o serviço disponível em http://www.byjg.com.br/xmlnuke-php/webservice.php/ws/cep?WSDL, e funciocou, sem problemas.
Depois disso, executei os mesmos passos para desenvolver um client para acessar o serviço que eu havia criado, porém nesta caso não fucionou, pois é apresentado o erro do lado client: org.xml.sax.SAXParseException: Premature end of file.
Já no servidor é apresentado o erro: 18:57:10,609 ERROR [SOAPFaultHelperJAXWS] SOAP request exception
java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage
at javax.xml.soap.SOAPMessage.setProperty(SOAPMessage.java:441)
Alguém sabe como solucionar este problema, já procurei no google, em diversos fóruns e não encontrei uma solução, se alguém puder me ajudar ficarei grato, pois estou há dias estudando e tentando encontrar uma solução.
Segue abaixo o log de erro completo para análise, caso seja necessário:
