I stuck in a issue, where I have to fill all slots from user.
Sharing required details -
I used Lex for writing Bot and intent Definition.
I exported Lex configuration to Alexa Skill kit.
Currently, I am facing issue, while fetching values of all slots of given intent from user.
Lambda code snippet -
#Override
public SpeechletResponse onIntent(SpeechletRequestEnvelope<IntentRequest> speechletRequestEnvelope) {
IntentRequest request = speechletRequestEnvelope.getRequest();
Session session = speechletRequestEnvelope.getSession();
log.info(String.format("onIntent. requestId : %s, sessionId : %s, Intent : %s", request.getRequestId(),
speechletRequestEnvelope.getSession().getSessionId(), speechletRequestEnvelope.getRequest().getIntent()));
Intent intent = request.getIntent();
String intentName = (intent != null) ? intent.getName() : null;
if ("HelloWorldIntent".equals(intentName)) {
return getHelloResponse();
} else if ("AMAZON.HelpIntent".equals(intentName)) {
return getHelpResponse();
} else if (LMDTFYIntent.MissingDrivesComplaint.name().equals(intentName)) {
return handleMissingDriveIntent(session, intent);
} else {
return getAskResponse("HelloWorld", "This is unsupported. Please try something else.");
}
}
private SpeechletResponse handleMissingDriveIntent(Session session, Intent intent) {
log.info(String.format("Executing intent : %s. Slots : %s", intent.getName(), intent.getSlots()));
Slot missingDriveSlot = intent.getSlot("missingDate");
Slot missingDrivesCountSlot = intent.getSlot("missingDrivesCount");
printSlots(intent.getSlots());
if(missingDriveSlot == null || missingDriveSlot.getValue() == null) {
printSlots(intent.getSlots());
log.info(String.format("Missing Drives slot is null"));
//return handleMissingDriveDialogRequest(intent, session);
ElicitSlotDirective elicitSlotDirective = new ElicitSlotDirective();
elicitSlotDirective.setSlotToElicit("missingDate");
SpeechletResponse speechletResponse = new SpeechletResponse();
speechletResponse.setDirectives(Arrays.asList(elicitSlotDirective));
SsmlOutputSpeech outputSpeech = new SsmlOutputSpeech();
outputSpeech.setSsml("On which date drives were missing");
speechletResponse.setOutputSpeech(outputSpeech);
return speechletResponse;
} else if(missingDrivesCountSlot == null || missingDrivesCountSlot.getValue() == null) {
printSlots(intent.getSlots());
log.info(String.format("Missing Drive Count is null"));
// return handleMissingDrivesCountDialogRequest(intent, session);
ElicitSlotDirective elicitSlotDirective = new ElicitSlotDirective();
elicitSlotDirective.setSlotToElicit("missingDrivesCount");
SpeechletResponse speechletResponse = new SpeechletResponse();
speechletResponse.setDirectives(Arrays.asList(elicitSlotDirective));
return speechletResponse;
} else if(missingDriveSlot.getValue() != null && missingDrivesCountSlot.getValue() != null) {
printSlots(intent.getSlots());
log.info(String.format("All slots filled."));
SpeechletResponse speechletResponse = new SpeechletResponse();
ConfirmIntentDirective confirmSlotDirective = new ConfirmIntentDirective();
speechletResponse.setDirectives(Arrays.asList(confirmSlotDirective));
return speechletResponse;
} else {
/*SpeechletResponse speechletResponse = new SpeechletResponse();
speechletResponse.setDirectives(Arrays.asList());*/
}
return null;
}
Check method -
handleMissingDriveIntent
Slots-
missingDate
missingDrivesCount
Question-
Amazon Echo Dot is saying - "There were a problem with a requested skill response". How can I figure out the reason ?
"There were a problem with a requested skill response"
Then Alexa responds to that error message back to you. That means there is a runtime error in your code.
You can check the CloudWatch logs from your lambda function (or using ask cli tool if you are using it). It can show you a line number where the error is happening. So you need to proceed from there.

I cannot really find an example on how to use this.
Right now, I'm doing like this:
// Request 10 connections.
ListConnectionsResponse response = peopleService.people().connections()
.list("people/me")
.setRequestSyncToken(true)
.setPageSize(10)
.setPersonFields("names,emailAddresses")
.execute();
I make some changes to my contacts (adding, removing, updating), then I do this:
// Request 10 connections.
ListConnectionsResponse response2 = peopleService.people().connections()
.list("people/me")
.setSyncToken(response.getNextSyncToken())
.setPageSize(10)
.setPersonFields("names,emailAddresses")
.execute();
But it seems like I cannot get the changes I've done earlier, not even if I do them directly from the UI. I'm pretty sure I'm using the sync token in the wrong way.
Update (19/02/2020): In this example I call the API requesting the sync token in the first request (I successfully get the contacts), pause the execution (by breakpoint), delete a contact and update another one (from the web page), resume the execution and then I call the API again with the sync token that I extracted from the previous call. The result is that no change was made for some reason:
// Build a new authorized API client service.
final NetHttpTransport HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
PeopleService peopleService = new PeopleService.Builder(HTTP_TRANSPORT, JSON_FACTORY, getCredentials(HTTP_TRANSPORT))
.setApplicationName(APPLICATION_NAME)
.build();
// Request 10 connections.
ListConnectionsResponse response = peopleService.people().connections()
.list("people/me")
.setPageSize(10)
.setPersonFields("names,emailAddresses")
.setRequestSyncToken(true)
.execute();
// Print display name of connections if available.
List<Person> connections = response.getConnections();
if (connections != null && connections.size() > 0) {
for (Person person : connections) {
List<Name> names = person.getNames();
if (names != null && names.size() > 0) {
System.out.println("Name: " + person.getNames().get(0)
.getDisplayName());
} else {
System.out.println("No names available for connection.");
}
}
} else {
System.out.println("No connections found.");
}
// CORRECT: 2 CONTACTS PRINTED
// CORRECT: THE SYNC TOKEN IS THERE
String syncToken = response.getNextSyncToken();
System.out.println("syncToken = "+syncToken);
// I SETUP A BREAKPOINT BELOW, I DELETE ONE CONTACT AND EDIT ANOTHER AND THEN I RESUME THE EXECUTING
// Request 10 connections.
response = peopleService.people().connections()
.list("people/me")
.setPageSize(10)
.setPersonFields("names,emailAddresses")
.setSyncToken(syncToken)
.execute();
// Print display name of connections if available.
connections = response.getConnections();
if (connections != null && connections.size() > 0) {
for (Person person : connections) {
List<Name> names = person.getNames();
if (names != null && names.size() > 0) {
System.out.println("Name: " + person.getNames().get(0)
.getDisplayName());
} else {
System.out.println("No names available for connection.");
}
}
} else {
System.out.println("No connections found.");
}
// WRONG: I GET "NO CONNECTIONS FOUND"
Something I've found out is that, when requesting or setting a sync token, you must iterate the entirety of the contacts for the nextSyncToken to be populated.
That means that as long as there is a nextPageToken (wink wink setPageSize(10)), the sync token will not be populated.
You could either:
A) Loop over all the contacts using your current
pagination, doing whatever you need to do at every
iteration, and after the last call retrieve the populated
sync token.
B) Iterate over all the contacts in one go, using the max
page size of 2000 and a single personField, retrieve the
token, and then do whatever you need to do. Note that if
you are expecting a user to have more than 2000
contacts, you will still need to call the next pages using
the nextPageToken.
Here is an exemple of a sync loop, adapted from Synchronize Resources Efficiently. Note that I usually use the Python client, so this Java code might not be 100% error free:
private static void run() throws IOException {
Request request = people_service.people().connections()
.list("people/me")
.setPageSize(10)
.setPersonFields("names,emailAddresses");
// Load the sync token stored from the last execution, if any.
// The syncSettingsDataStore is whatever you use for storage.
String syncToken = syncSettingsDataStore.get(SYNC_TOKEN_KEY);
String syncType = null;
// Perform the appropiate sync
if (syncToken == null) {
// Perform a full sync
request.setRequestSyncToken(true);
syncType = "FULL";
} else {
// Try to perform an incremental sync.
request.setSyncToken(syncToken);
syncType = "INCREMENTAL";
}
String pageToken = null;
ListConnectionsResponse response = null;
List<Person> contacts = null;
// Iterate over all the contacts, page by page.
do {
request.setPageToken(pageToken);
try {
response = request.execute();
} catch (GoogleJsonResponseException e) {
if (e.getStatusCode() == 410) {
// A 410 status code, "Gone", indicates that the sync token is
// invalid/expired.
// WARNING: The code is 400 in the Python client. I think the
// Java client uses the correct code, but be on the lookout.
// Clear the sync token.
syncSettingsDataStore.delete(SYNC_TOKEN_KEY);
// And anything else you need before re-syncing.
dataStore.clear();
// Restart
run();
} else {
throw e;
}
}
contacts = response.getItems();
if (contacts.size() == 0) {
System.out.println("No contacts to sync.");
} else if (syncType == "FULL"){
//do full sync for this page.
} else if (syncType == "INCREMENTAL") {
//do incremental sync for this page.
} else {
// What are you doing here???
}
pageToken = response.getNextPageToken();
} while (pageToken != null);
// Store the sync token from the last request for use at the next execution.
syncSettingsDataStore.set(SYNC_TOKEN_KEY, response.getNextSyncToken());
System.out.println("Sync complete.");
}

I'd create one custom mediator in my WSO2 ESB project at the OutSequence.
I would like to change the result in SOAP Envelope being send from the back end to the consumer. But with a little bit of adjustment to the data according to the result.
this is the SOAP Envelope
<soapenv:Bodyxmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<jsonObject>
<serviceRequestID>12345</serviceRequestID>
<statusCode>1</statusCode>
<errorCode></errorCode>
<errorDescription></errorDescription>
<addressID>1.23456794E9</addressID>
<source>consumer name</source>
<requestId>910514</requestId>
</jsonObject>
I want to create a custom mediator to set the Error Description base on the Error Code.
For example,
if error code 1 = error description = one
if error code 2 = error description = two
if error code 3 = error description = three
This is my custom mediator code.
private void ResponseLogging(MessageContext mc) throws OMException{
try {
String errorCode = mc.getEnvelope().getBody().getFirstElement().getFirstChildWithName(new QName("errorCode")).getText();
String errorDescription = null;
if(errorCode.equals("1")) {
errorDescription = "One";
}else if(errorCode.equals("2")) {
errorDescription = "Two";
}else if(errorCode.equals("3")) {
errorDescription = "Three";
}
mc.getEnvelope().getBody().getFirstElement().getFirstChildWithName(new QName("errorDescription")).setText(errorDescription);
} catch (Exception e) {
log.error(e.getMessage(), e);
}
}
Expected response,
<soapenv:Bodyxmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<jsonObject>
<serviceRequestID>12345</serviceRequestID>
<statusCode>1</statusCode>
<errorCode>1</errorCode>
<errorDescription>One</errorDescription>
<addressID>1.23456794E9</addressID>
<source>consumer name</source>
<requestId>910514</requestId>
</jsonObject>
But now, I only get the error description as null.
kindly help. any advice would be great !
Thanks.
UPDATED !
Apparently, after set the value using the setText() method. The error description value change to One as expected in the log.
</statusCode><errorCode>1</errorCode><errorDescription>One</errorDescription>
But when the response is sent back to the client, it still null value.
{"serviceRequestID": "12345","statusCode": 1,"errorCode": "1", "errorDescription": "","addressID": 1.23456794E9,"source": "consumer name", "requestId": "910514"}
Try this;
private void ResponseLogging(MessageContext mc) throws OMException{
try {
String errorCode = mc.getEnvelope().getBody().getFirstElement().getFirstChildWithName(new QName("jsonObject")).getFirstChildWithName(new QName("errorCode")).getText();
String errorDescription = null;
if(errorCode.equals("1")) {
errorDescription = "One";
}else if(errorCode.equals("2")) {
errorDescription = "Two";
}else if(errorCode.equals("3")) {
errorDescription = "Three";
}
mc.getEnvelope().getBody().getFirstElement().getFirstChildWithName(new QName("jsonObject")).getFirstChildWithName(new QName("errorDescription")).setText(errorDescription);
} catch (Exception e) {
log.error(e.getMessage(), e);
}

The following snippet is able to return all the cars in my database as a JSON when I call the URL 1 and I can display them in the browser. However, when I use the URL 2, I get nothing and the browser displays the 404 error. But it is weird that the error does not show the message "Car not found". It shows "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.".
I tested the RegexUtil class and it does return the Long as 1 when I call the URL 2 and Long equal to null when I call the URL 1.
What am I doing wrong?
1) http://localhost:8080/Cars/cars
2) http://localhost:8080/Cars/cars/1
String requestUri = request.getRequestURI();
Long id = RegexUtil.matchId(requestUri);
if (id != null) {
//this if test is never executed even when id != null
// id was informed
Car car = carService.getCar(id);
if (car != null) {
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json = gson.toJson(car);
ServletUtil.writeJSON(response, json);
} else {
response.sendError(404, "Car not found");
}
} else {
//this else executes fine
// Show car list
List<Car> cars = carService.getCars();
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json = gson.toJson(cars);
ServletUtil.writeJSON(response, json);
}
Issue resolved.
The servlet annotation was incorrect.
The asterisk was missing
#WebServlet(urlPatterns = { "/cars/*" },
I'm working with a project, where I have EMF model 'A' which is referenced in many other models 'B','C'... etc. What I want is I want to give a rename feature for these resources. So when user renames 'A', its references have to be updated.
Please provide some idea on it, if there is any frame work for this or I have to get all the references and then programmatically iterate and update the references.
I solved the same problem in another way.
The fundamental problem is that a referenced resource file might be renamed, and this breaks the references.
Instead of a refactoring that automatically updates all references I created a Repair File References command, which the user can invoke on an edited model.
The command performs these steps:
Prompts the user to select a missing resource to repair
Prompts the user to select a replacement file
Updates all objects in the model that has a proxy URI that matches the missing resource. Replaces proxies with resolved objects in the new resource.
If you still want to make a refactoring instead, I think you anyway can use my code as a starting point.
/**
* Locates and fixes unresolved references in a model.
*/

public static final String COMMAND_ID = Activator.PLUGIN_ID + ".commands.repairReferences";

I am new to AWS, Can any one please help me how to create users on virtual machine using java code. I have created windows ec2 instance and able to connect using sshClient, but unable to create users. I dont have any idea about how it can be done.
[I am new to stack overflow please forgive me if wrong formatting]
Answering my own question... It may help someone..
You can use execute command to create user on remote windows...
Example:
public boolean executeCommands(String commands, SSHRequestParam param)
throws Exception,IOException {
boolean response = false;
try {
Connection conn = getConnection(param);
Session sess = conn.openSession();
sess.execCommand(commands);
sess.waitForCondition(ChannelCondition.EXIT_SIGNAL, 0);
InputStream stdout = new StreamGobbler(sess.getStdout());
BufferedReader br = new BufferedReader(
new InputStreamReader(stdout));
while (true) {
String line = br.readLine();
if (line == null)
break;
response=true;
System.out.println(line);
}
InputStream stderr = new StreamGobbler(sess.getStderr());
BufferedReader br1 = new BufferedReader(new InputStreamReader(
stderr));
while (true) {
String line = br1.readLine();
if (line == null)
break;
response=false;
System.out.println(line);
}
/* Show exit status, if available (otherwise "null") */
System.out.println("ExitCode: " + sess.getExitStatus());
/* Close this session */
System.out.println("closing session");
sess.close();
closeConnection(conn);
} catch (IOException e) {
System.out.println("Exception..while executing command.: " + commands);
e.printStackTrace();
}
System.out.println("Command executed : "+response);
return response;
}
public void createUser(String userName, String password,SSHRequestParam param)
throws Exception,IOException {
String command = "net user " +userName+" "+password+" /add" ;
if(executeCommands(command,param))
System.out.println("User created successfully");
else
System.out.println("User didn't create....");
}
In above example param variable stores the parameters to connect to the server i.e. hostname, username, password....
