I have a wildcard cert for *.mydomain.com (the names have been changed to protect the innocent...that is NOT the real domain :) )
When using a correctly implemented Java HttpClient 4 (the issue is not seen in FF), Service calls made via HTTPS to api.mydomain.com are successful where as identical service calls made to non-production subdomains of mydomain.com (developer.mydomain.com, api-beta.mydomain.com, api-uat.mydomain.com) generate this Exception with the Test harness code below:
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

at com.mydomain.httpclientexample.HttpClientTestv2.main(HttpClientTestv2.java:54)
While the SLL cert on developer.mydomain.com, api-beta.mydomain.com & api-uat.mydomain.com appears to be the same WC cert as api.mydomain.com, the exception is not seen on api.mydomain.com but it is on the other sub-domains. The code works on api-na.mydomain.com and should work on the non-production subdomains.
Any ideas?
Client code: As you can see, I can easily change the ADDRESS_VALIDATION_SERVICE_URI I want to call. The api.mydomain.com one works without the SSLPeerUnverifiedException; the other three URIs throw the exception...

I have a very basic Vertx demo I'm trying to create that fetches a JWK from an endpoint and creates an RSAPublicKey for verifying a JWT signature:
package example;

import com.auth0.jwt.algorithms.Algorithm;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.interfaces.RSAPublicKey;
import com.auth0.jwt.interfaces.RSAKeyProvider;
import java.security.interfaces.RSAPrivateKey;
public class MainVerticle extends AbstractVerticle {
#Override
public void start(Promise<Void> startPromise) throws Exception {
HttpServer server = vertx.createHttpServer();
Router router = Router.router(vertx);
router.route().handler(routingContext -> {
String authHeader = routingContext.request().getHeader("Authorization");
// pull token from header
String token = authHeader.split(" ")[1];
URL jwksEndpoint = null;
try {
jwksEndpoint = new URL("http://localhost:1080/jwks");
} catch (MalformedURLException e) {
e.printStackTrace();
}
JwkProvider jwkProvider = new UrlJwkProvider(jwksEndpoint);
RSAKeyProvider keyProvider = new RSAKeyProvider() {
#Override
public RSAPublicKey getPublicKeyById(String kid) {
//Received 'kid' value might be null if it wasn't defined in the Token's header
RSAPublicKey publicKey = null;
try {
publicKey = (RSAPublicKey) jwkProvider.get(kid).getPublicKey();
} catch (JwkException e) {
e.printStackTrace();
}
return publicKey;
}
#Override
public RSAPrivateKey getPrivateKey() {
return null;
}
#Override
public String getPrivateKeyId() {
return null;
}
};
Algorithm algorithm = Algorithm.RSA256(keyProvider);
JWTVerifier verifier = JWT.require(algorithm)
.withIssuer("auth0")
.build();
DecodedJWT jwt = verifier.verify(token);
System.out.println(jwt);
routingContext.next();
});
router.route("/hello").handler(ctx -> {
ctx.response()
.putHeader("content-type", "text/html")
.end("<h1>Hello from non-clustered messenger example!</h1>");
});
server.requestHandler(router).listen(8888, http -> {
if(http.succeeded()) {
startPromise.complete();
System.out.println("HTTP server started on port 8888");
} else {
startPromise.fail(http.cause());
}
});
}
}
The problem is that when I make request to the /hello endpoint, the application immediately returns a 500. But nothing appears in the logs (even at debug level).
I've tried manually specifying the kid property to rule out the jwkProvider not returning properly
I'm at a loss at how to gain any more insight into what is failing.
Turns out to completely be my oversight. Wrapping that verifier.verify() call in a try/catch showed me that I was expecting an issuer. This is the same problem I was having while trying to achieve this in Quarkus! I was able to remove that from the builder and now this works perfectly.
After hours of trawling the internet and trying to make sense of the documentation I seem unable to find a resolution to this problem.
I have an application which is using an ASyncTask to connect to a server I have 3 addresses to "test" the connection.
Now the problem is when I use the Myconnection.connect() the background task just hangs if there is either no known address or a dead link.
How can I test this connection when with a dead link or dead server it hangs and does not receive any response
The errors in the Logcat are

I have written code for accessing GCS bucket to store files thru API in java which takes JSON credential file. I have created that JSON file from google console. I need to automate the JSON file or key rotation for every 90 days. How to regenerate/rotate that JSON file? I am a newbie to GCS.

This what I have written to call the API But i am not sure if this is the way to call it.
try this solution, it worked for me
private static void createNewKey(IamRequestInitializer req) throws IOException, GeneralSecurityException {
Iam iam = jsonAuthentication();
CreateServiceAccountKeyRequest keyRequest = new CreateServiceAccountKeyRequest();
keyRequest.setKeyAlgorithm(KEY_ALGO);
String account = SERVICE_ACCOUNT_URL + SERVICE_ACCOUNT_EMAIL;
iam.projects().serviceAccounts().keys().create(account, keyRequest);
String requestString = BASE_URL + SERVICE_ACCOUNT_EMAIL + KEY;
ServiceAccountKey result = getServiceAccountKey(req, iam, requestString);
String jsonKey = new String(result.decodePrivateKeyData());
System.out.println(jsonKey);
JsonFileUtil.createFile(JSON_KEY_FILE_NAME, jsonKey);
}
private static <T> T getServiceAccountKey(IamRequestInitializer req, Iam iam, String requestString)
throws IOException {
MyIamRequest<String> request = new MyIamRequest<String>(iam, HttpMethods.POST, requestString, String.class,
ServiceAccountKey.class);
request.setKey(API_KEY);
request.setFields(
"keyAlgorithm,name,privateKeyData,privateKeyType,publicKeyData,validAfterTime,validBeforeTime");
req.initializeJsonRequest(request);
System.out.println(request.getRequestHeaders());
return (T) request.execute();
}
If you're using a JSON credential file, you are acting as some particular service account which is a member of your project and has access to the files.
Service accounts can be programmatically controlled for exactly this sort of use case. The IAM Service Account API controls service accounts, and the two methods you want for key rotation are serviceAccount.keys.create() and serviceAccount.keys.delete().
The result of the create() call (if you pass in the private key type TYPE_GOOGLE_CREDENTIALS_FILE), will be a new, valid JSON credential file for your service account.
#user7049946
ServiceAccountKey response = getServiceAccountKey(req, iam, requestString);
CreateNewJson.createFile("NEW_JSON_KEY_FILE_NAME", new String(response.decodePrivateKeyData()));
create new class to convert that conent into new file.
public class CreateNewJson {
public static void createFile(String filename, String content) throws IOException {
FileOutputStream fileOutputStream = null;
File file;
file = new File(filename);
fileOutputStream = new FileOutputStream(file);
if (!file.exists()) {
file.createNewFile();
}else{
file.delete();
file.createNewFile();
}
byte[] contentInBytes = content.getBytes();
fileOutputStream.write(contentInBytes);
fileOutputStream.flush();
fileOutputStream.close();
System.out.println("File Created");
}

I am using Apache HttpClient to put/get customized object using REST APIs. Below is the sample code. My putObject() method works fine and I could serialize Person object and put properly. However, while getting the object, I got below error:
Exception in thread "main" java.lang.ClassCastException: [B cannot be cast to Person at MyTest.demoGetRESTAPI(MyTest.java:88) at MyTest.main(MyTest.java:21)
Seems the code to build Person object out of response entity is not correct
HttpEntity httpEntity = response.getEntity();
byte[] resultByteArray = EntityUtils.toByteArray(httpEntity);
Person person = (Person)SerializationUtils.deserialize(resultByteArray);
Am I doing somthing wrong while getting byte[] array and converting to Person object. Please help me out to solve this issue.
Complete Example Program:
import java.io.Serializable;
import org.apache.commons.lang.SerializationUtils;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPut;
import org.apache.http.entity.SerializableEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
public class MyTest {
public static void main(String[] args) throws Exception {
putObject();
getObject();
}
public static void putObject() throws Exception
{
HttpClient httpClient = new DefaultHttpClient();
Person person = new Person();
person.setName("Narendra");
person.setId("1");
try
{
//Define a postRequest request
HttpPut putRequest = new HttpPut("http://localhost:9084/ehcache-server/rest/screeningInstance/2221");
//Set the API media type in http content-type header
putRequest.addHeader("content-type", "application/x-java-serialized-object");
//Set the request put body
SerializableEntity personSEntity = new SerializableEntity(SerializationUtils.serialize(person));
putRequest.setEntity(personSEntity);
//Send the request; It will immediately return the response in HttpResponse object if any
HttpResponse response = httpClient.execute(putRequest);
//verify the valid error code first
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode != 201)
{
throw new RuntimeException("Failed with HTTP error code : " + statusCode);
}
}
finally
{
//Important: Close the connect
httpClient.getConnectionManager().shutdown();
}
}
public static void getObject() throws Exception
{
DefaultHttpClient httpClient = new DefaultHttpClient();
try
{
//Define a HttpGet request; You can choose between HttpPost, HttpDelete or HttpPut also.
//Choice depends on type of method you will be invoking.
HttpGet getRequest = new HttpGet("http://localhost:9084/ehcache-server/rest/screeningInstance/2221");
//Set the API media type in http accept header
getRequest.addHeader("accept", "application/x-java-serialized-object");
//Send the request; It will immediately return the response in HttpResponse object
HttpResponse response = httpClient.execute(getRequest);
//verify the valid error code first
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode != 200)
{
throw new RuntimeException("Failed with HTTP error code : " + statusCode);
}
//Now pull back the response object
HttpEntity httpEntity = response.getEntity();
byte[] resultByteArray = EntityUtils.toByteArray(httpEntity);
Person person = (Person)SerializationUtils.deserialize(resultByteArray);
}
finally
{
//Important: Close the connect
httpClient.getConnectionManager().shutdown();
}
}
}
class Person implements Serializable{
String name;
String id;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
#Override
public String toString() {
return "Person [name=" + name + ", id=" + id + "]";
}
}
I got the solution. It was mistake in my code:
While putting object, I have written below code. That was doing two time serialization. First from Person object to byte[] and second from byte[] to byte[].
SerializableEntity personSEntity = new SerializableEntity(SerializationUtils.serialize(person));
putRequest.setEntity(personSEntity);
This is the right approach:
SerializableEntity personSEntity = new SerializableEntity(person);
putRequest.setEntity(personSEntity);
After getting binary from REST, code should be like below to get Object:
HttpEntity httpEntity = response.getEntity();
InputStream inputStream = null;
try {
inputStream = httpEntity.getContent();
Person p = (Person) SerializationUtils.deserialize(inputStream);
System.out.println("Person:" + p.getName());
}
finally {
inputStream.close();
}
This worked like CHARM !!
The overall topic is actually like a Chat Application sending a simple string message to an aws server, which uses the message to make calculations server-side and sending a simple string message as a solution back to the client.
Server: I have written a Server Class and deployed it through eclipse to aws beanstalk. (see code Server)
Client: My android device creates a socket, establishes a successful connection to my aws beanstalk ip and 8080 port, while iterating through an endless while loop in a thread listening to incoming messages from the server. (see code Client and ClientThread)
Problem: My problem is that I don't know how to check whether the server receives the connection request and messages from the client. How do I make sure, that code on aws beanstalk actually runs in background continuously listening for incoming connections? I have deployed the code, does aws beanstalk automatically start the main method of the Server Class and runs it infinitely?
Here's the server code:
