Olá colegas!
Estou tendo um problema que não consigo fazer funcionar já faz um certo tempo…
Eu fiz uma classe cliente JAXR para fazer Service Doscovery em um Service Registry (Weblogic Aqualogic Service Registry - ALSR) e retorna uma lista de Strings com os WSDLs dos web services encontrados.
Em seguida, eu fiz um cliente JAX-WS que pega cada WSDL e invoca (usando o Port ou o Dispatch).
O problema é que o cliente JAXR funciona normalmente e retorna os WSDLs. Mas logo em seguida, quando vai para a invocação do web service, ele me dá este erro:
javax.xml.ws.WebServiceException: Failed to access the WSDL at: http://xxx.yyy.zzz.com:7070/sampleGateway?WSDL. It failed with:
http://xxx.yyy.zzz.com:7070/sampleGateway?WSDL.

Eu imaginei que poderia ser um erro no WSDL, mas não é porque eu consigo invocar o web service se eu não fizer o service discover com o JAXR antes.
Aqui está o test case que usa o JAXRCLient e tenta fazer a invocação do web service:
public void testStaticInvocationClient() throws JAXRException, MalformedURLException{
final QName SERVICE_QNAME = new QName("http://com/acme/soa", "SampleService");
URL baseUrl = SampleService.class.getResource(".");
Collection<String> wsdlAddresses = new JAXRClient().findServicesWsdlURIs("sample%");
for (String wsdlAddress : wsdlAddresses) {
System.err.println("-> " + wsdlAddress);
SampleService service = new SampleService(new URL(baseUrl, wsdlAddress), SERVICE_QNAME);
Sample servicePort = service.getSampleSoapPort();
System.err.println("Starting Static Service Invocation...");
/*call "execute" method in the sevice port to invoke remote web service
*as long as we have a Handler registered in JAX-WS runtime,
*the 'handleMessage' method in that handler will web called before the
*remote invocation occurs.
*/
String returnedString = servicePort.execute("Test Message");
//output results from server
System.err.println("Response from srv: " + returnedString);
}
System.err.println("test finished!");
}E aqui está o código do JAXRClient (espero que sirva pra alguém tb!):

}
É muito estranho: eu consigo fazer as coisas funcionarem isoladas, mas se eu fizer o JAXRClient procurar os serviços no ALSR, parece que ele “trava” o runtime do JAX-WS, e eu não consigo mais fazer qualquer invocação de qualquer we service no teste.
Agradeço qualuqer ajuda!!
Obrigado desde já!!
Abraço a todos,
