I have a web application that does authentication and then checks for a cookie in request to allow the subsequent calls from the same client. I have written a piece of code which works just fine when I run it from eclipse, but fails when run from the android emulator. Here is what I did
Class to create a webresource for a URI and bind a filter to it to attach cookies to the request
public class TolvenRestClient {
private static Client client;
private static final ThreadLocal<String> instance = new ThreadLocal<String>();
static {
ClientConfig config = new DefaultClientConfig();
client = Client.create(config);
client.setFollowRedirects(true);
}
private Client getClient() {
return client;
}
public WebResource getResource(String path){
WebResource webResource = getClient().resource(path);
webResource.addFilter(new ClientFilter() {
@Override
public ClientResponse handle(ClientRequest clientRequest) throws ClientHandlerException {
if (instance.get() != null) {
clientRequest.getHeaders().putSingle("Cookie", "SSOCookie=" + instance.get());
}
ClientResponse clientResponse = getNext().handle(clientRequest);
String cookieName = "SSOCookie";
System.out.println("cookies "+clientResponse.getCookies());
for (NewCookie newCookie : clientResponse.getCookies()) {
if (cookieName.equals(newCookie.getName())) {
String extendedSessionId = newCookie.getValue();
instance.set(extendedSessionId);
break;
}
}
return clientResponse;
}
});
return webResource;
}
and then a sample code to trigger the webservice calls
RestClient client = new RestClient();
MultivaluedMap<String, String> formData = new MultivaluedMapImpl();
formData.add("username", "demo");
formData.add("password", "1234qwer");
formData.add("realm", "tolven");
WebResource webResource = client.getResource("https://dev.example.com:8443/gatekeeper/rs/authenticate/login");
ClientResponse response = webResource.type(MediaType.APPLICATION_FORM_URLENCODED).post(ClientResponse.class,formData);
//ClientResponse response = webResource.accept("text/html").get(ClientResponse.class);
System.out.println("Here ....." + response.toString());
webResource = client.getResource("https://dev.example.com:8443/api/vestibule/accountList");
response = webResource.get(ClientResponse.class);
Accounts accounts = response.getEntity(Accounts.class);
This code works just fine when run from eclipse. But when run inside android emulator it fails to read cookies from client response
I get the below exception

Has anybody tried using Jersey client on android before and seen this issue?
