Question

I am new to webservices and trying to write a RESTFul webservice’s client using RestTemplate.
I am using org.springframework.http.converter.xml.MarshallingHttpMessageConverter as message converter and org.springframework.oxm.xstream.XStreamMarshaller as marshaller.

Is there any way to debug this further or find out the root cause of this issue?

My consumer class looks like this –

@SuppressWarnings("unchecked")
public List<Deal> getClientInformation() throws RestClientException {
    return restTemplate.getForObject(webServiceURL, List.class);

}

Exception :

Exception in thread "main" org.springframework.web.client.ResourceAccessException: I/O error: Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect
at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:359)

Answer 1

the webServiceURL you are trying to call is not reachable. Ensure the webServiceURL path is correct and is listening.

PS. Also check if there is some firewall issue at Server side.

Wireshark may help you to debug further.
