Push data from Dynamo DB to elasticsearch using java

Hi i have created a handler in java for getting the events from dynamo DB
Here is my code
package com.Lambda.dynamodb;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.LambdaLogger;
import com.amazonaws.services.lambda.runtime.RequestHandler;
import com.amazonaws.services.lambda.runtime.events.DynamodbEvent;
import com.amazonaws.services.lambda.runtime.events.DynamodbEvent.DynamodbStreamRecord;
public class DDBEventProcessor implements
RequestHandler<DynamodbEvent, String> {
public String handleRequest(DynamodbEvent ddbEvent, Context context) {
for (DynamodbStreamRecord record : ddbEvent.getRecords()){
System.out.println(record.getEventID());
System.out.println(record.getEventName());
System.out.println(record.getDynamodb().toString());
}
return "Successfully processed " + ddbEvent.getRecords().size() + " records.";
}
}
Lambda function able to write the events in cloudwatch but the challenge is i have to index all the streamed records to the AWS elasticsearch service endpoint and index it.
while search through blogs i got few code samples in python and node.js but my requirement is i have to build this lambda function in java
Could anyone please suggest how to achieve this in java lambda function?

Hi i have included the code below may helpful to some one. Dynamo DB streams to index the document in elasticsearch both inside AWS and outside AWS

This is just a sample code has to be modified based on our requirements

Java - JWT Token Invalid Signature

I have a problem getting my JWT Token verified, despite it giving me the correct payload.
Excuse me if I'm a little insecure in this part of the code, since this was handed out by our teacher via a template, but we are unable to reach him.
We had to make some changes to the code itself, since it had the username put into the token and we want the email put in.
We are using something called UserPrincipal, what I can understand, its used to determine access rights to a file or object and originally we used roles to determine what users had access to which endpoints. This is not the case in this project, since its a short demo based on other features.
How does our user principal class look like?
package rest;
import entity.User;
import java.security.Principal;
public class UserPrincipal implements Principal {
private String name;
private String email;
public UserPrincipal(User user) {
this.email = user.getEmail();
}
public UserPrincipal(String email) {
super();
this.email = email;
}
#Override
public String getName() {
return email;
}
}
See, here the user principal used to also get a list of roles and instead of a email, it got a username.
Where do we use this user principal? Well, we use it when we generate our token. This is also here we have our endpoint, yes it should be moved to our interface class.

public class JWTSecurityContext implements SecurityContext {
UserPrincipal user;
ContainerRequestContext request;

this.user = user;
this.request = request;
}
#Override

Scheduled task through annotations in servlet is not working

I have a server that handles requests, and with regular intervals (every 1-2 minutes) needs to call another server and update a list of objects that is used to create the response to the request. Inspired by for example the accepted answer for this question, I tried to use the Schedule annotation, but can't get it to work.
How to run a background task in a servlet based web application?
A simplified view of the server is:
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
#WebServlet(name = "MyServer", urlPatterns = {"/data/*", "/scheduled/*"}, loadOnStartup = 1)
public class MyServlet extends HttpServlet {
private static final String UTF_8 = "UTF-8";
private static final String APPLICATION_JSON = "application/json";
private static final long serialVersionUID = 1L;
private static connector connector;
public MyServlet() {
super();
}
public void destroy() {}
#Override
public void init() throws ServletException {
connector = new connector();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String path = request.getServletPath();
String pathInfo = request.getPathInfo().substring(1);
response.setContentType(APPLICATION_JSON);
response.setCharacterEncoding(UTF_8);
if (path.endsWith("/data")) {
List<DataItem> dataItems = connector.currentData;
response.getWriter().write(JsonUtility.convertToJsonString(dataItems));
} else if (path.endsWith("/scheduled")) {
connector.fetchData();
response.getWriter().write("Done");
} else {
response.getWriter()
.write(pathInfo + " Is not Found but not returning 404");
return;
}
}
}
The connector class that is supposed to update the stored data from the other server at regular intervals is:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.ejb.Lock;
import javax.ejb.LockType;
import javax.ejb.Schedule;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import com.google.gson.Gson;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;
#Startup
#Singleton
public class Connector {
public List<DataItem> currentData = new LinkedList<>();
#Lock(LockType.READ)
#Schedule(second = "*", minute = "*/2", hour = "*", persistent = false)
public void fetchNews() {
logger.debug("Fetching data");
String response = sendGet(url, bearerToken);
JsonObject json = new Gson().fromJson(response, JsonObject.class);
//Transform the response to a list of DataItems.
List<DataItem> retrievedData = toDataList(json)
System.out.println(retrievedData);
synchronized(currentData) {
currentData = retrievedData;
}
}
private String sendGet(String path, String authorizationProperty) {
URL url;
try {
url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Authorization", authorizationProperty);
conn.setRequestProperty("Content-Type","application/json");
conn.setRequestMethod("GET");
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8));
String output;
StringBuffer response = new StringBuffer();
while ((output = in.readLine()) != null) {
response.append(output);
}
in.close();
return response.toString();
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
}
However, the method fetchData is not firing every second minute as I was expecting. I don't know what I am missing. I have played around a bit with adding/removing the #Startup annotation, creating an instance of the class in the init() method on the server, but still have no result.

Error jersey Rest client using sparql queries

I am trying to execute sparql queries from jersey client but the problem that the execution returns 200 status and the result is null.But , when I execute the same query on POSTMAN the status is 200 but the result is not null.

that is the result of running the client :
SimpleJerseyClient(): uri = SELECT+*+WHERE+%7B+%3Fa+%3Fb++%7D
200
org.glassfish.jersey.client.internal.HttpUrlConnector$2#cd3fee8
null
Thanks

This could be caused by a parsing error on the side of the endpoint. I've found that Fuseki (is that your underlying triple store?) requires spaces to be encoded as %20 rather than +. However, I managed to run + encoded queries from the browser just fine. Perhaps replacing + with %20 in the encoded query string will resolve the issue. Otherwise, hope someone finds this useful.
sparqlQueryUri = uc.encode(query).replaceAll("\\+", "%20");

How to get HttpOnly cookie using jsoup

This is described as an httpOnly cookie. How can I get it?
