Error consuming WS without ssl - soap

Question

I'm trying to consume a service that does not need a certificate.
It only receives username and password as the property of the request.
I'm using the maven-jaxb2-plugin plugin to generate the code.
I tried copying using the following commands:
mvn generate-sources -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true
and
mvn generate-sources
But I have received the following error:
org.springframework.ws.client.WebServiceIOException: I/O error: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
This is my setup method:
#Bean
Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setPackagesToScan("ce.gov.s2gpr.compras.licita.business.model.service.bean");
return jaxb2Marshaller;
}
#Bean
public WebServiceTemplate webServiceTemplate() {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
webServiceTemplate.setMarshaller(jaxb2Marshaller());
webServiceTemplate.setUnmarshaller(jaxb2Marshaller());
webServiceTemplate.setDefaultUri(defaultUri);
webServiceTemplate.setMessageSender(webServiceMessageSender());
return webServiceTemplate;
}
#Bean
public WebServiceMessageSender webServiceMessageSender() {
HttpComponentsMessageSender httpComponentsMessageSender = new HttpComponentsMessageSender();
// timeout for creating a connection
httpComponentsMessageSender.setConnectionTimeout(timeout);
// when you have a connection, timeout the read blocks for
httpComponentsMessageSender.setReadTimeout(timeout);
httpComponentsMessageSender.setCredentials(new UsernamePasswordCredentials(userName, userPassword));
return httpComponentsMessageSender;
}
This is my method that consumes the service:
#SuppressWarnings("unchecked")
public AtualizacaoItensGruposResponse testeSoap(PgeTO dto) {
ObjectFactory factory = new ObjectFactory();
AtualizacaoItensGrupos itens = factory.createAtualizacaoItensGrupos();
itens.setArg0(dto);
JAXBElement<AtualizacaoItensGrupos> request = factory.createAtualizacaoItensGrupos(itens);
try {
// webServiceTemplate.marshalSendAndReceive(request);
webServiceTemplate.marshalSendAndReceive(itens);
return null;
} catch (Exception e) {
log.error(e.getMessage());
}
}
