Please can you help. I have a Codenameone app that issues a GET request to a cloud Tomcat 8 server, and expects back some response JSON. Importantly this is a HTTPS call.
When i run the request in Postman it works fine:
https://www.mydomain.co.uk:8443/MyProject/v1/generate_token
The same URL through my browser works and shows as 'Secure' and i can see my certificate details. I have bought a certificate for my SSL/TLS configuration, and seems to function fine in the logs on startup.
In the simulator i get back the following error at the point of reading the response back from the URL call - which i guess must be encrypted:
Exception: 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

Why should the app be any different to Postman making the call (the Network Monitor window confirms the same URL call) ?
None of the logs are being updated after my call, so nothing to check there. I haven't made any changes to my app (which was working) since moving from http to https.
Here is the CN1 code making the call:
public String fetchTokenIntoStorage(String userName, String password) {
ConnectionRequest r = new ConnectionRequest();
r.setUrl(Constants.URL_HOST_PORT + "/MyProject" + Constants.LIVE_OR_TEST
+ "/v1/generate_token");
r.addRequestHeader("Content-Type", "application/json");
r.addRequestHeader("userName", userName);
r.addRequestHeader("password", password);
r.setHttpMethod("GET");
r.setFailSilently(false);
r.setPost(false);
// show spinning dialog while connecting
InfiniteProgress prog = new InfiniteProgress();
Dialog dlg = prog.showInifiniteBlocking();
r.setDisposeOnCompletion(dlg);
NetworkManager.getInstance().setTimeout(10000);
// NetworkManager.getInstance().addErrorListener(new ActionListener() {
//
// @Override
// public void actionPerformed(ActionEvent evt) {
// MessageBox.showDialogMessage("Unable to connect to server. Please
// retry later.");
// }
// });
// NetworkManager.getInstance().updateThreadCount(2);
NetworkManager.getInstance().addToQueueAndWait(r);
if (r.getResponseData() != null) {
JSONParser parser = new JSONParser();
Map<String, Object> json = null;
try {
json = parser.parseJSON(new InputStreamReader(new ByteArrayInputStream(r.getResponseData())));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (json.get("error") != null) {
return String.valueOf(json.get("error"));
}
JwtRecord record = new JwtRecord();
record.userId = Integer.parseInt(String.valueOf(json.get("userId")));
record.jsonWebToken = (String) json.get("jwt");
record.theme = "LIGHT";
Storage.getInstance().writeObject("MyToken", record);
return "";
}
if (!r.getResponseErrorMessage().equalsIgnoreCase("")) {
return r.getResponseErrorMessage();
} else {
return "Unable to connect to server. Please check connection.";
}
}
Stepping through the code it seems to error just after
NetworkManager.getInstance().addToQueueAndWait(r);
The r.getResponseData() and r.getResponseErrorMessage() are null.
Many thanks
