I am working with java program connected with MongoDB when I run the program it will show an error but code is working.
MongoDB has a database called MongoDB and inside that, there is a collection called seatbooking with two columns(name,seatnumber).
This is my code:
MongoClient mongoClient = new MongoClient("localhost", 27017);
System.out.println("connection is established");
MongoDatabase mongoDatabase = mongoClient.getDatabase("MongoDB");
MongoCollection mongoCollection = mongoDatabase.getCollection("seatbooking");
Document document = new Document("name","shenal");
document.append("seatnumber",20);
mongoCollection.insertOne(document);
when I run this code my output is:

The logging output doesn't show any result for the insertOne operation.
If you are using MongoDB Java Driver version prior to 4.0, there is no acknowledgement object returned. But, the version 4's insertOne method returns a InsertOneResult object. This is a new feature in 4.0 (in prior version's the method returned a void).
You can use the following code to check the insert's outcome as follows (with version 4.0):
try {
InsertOneResult insertResult = collection.insertOne(document);
System.out.println("Document inserted with ID: " + insertResult.getInsertedId());
}
catch(MongoWriteException e) {
// write failure happened, handle it here...
}
I'm working with AWSIotMqttClient to subscribe and publish to topics. After I received all messages I want to stop my application. But it works infinitely long. Here a simple code which works infinitely, even without subscribes:
SampleUtil.KeyStorePasswordPair keyStorePasswordPair =
SampleUtil.getKeyStorePasswordPair("certificate.pem", "privateKey.pem");
AWSIotMqttClient client = new AWSIotMqttClient(
"mqtt-broker.address",
"deviceID",
keyStorePasswordPair.keyStore,
keyStorePasswordPair.keyPassword);
client.connect();
client.disconnect();
Here is my logs:

I can stop my application with System.exit(0) but it is undesirable for me. I expect that after all code is passed, the application will stop.

Please help me, how can I fix this problem.
I am trying to connect to an Elasticsearch cluster form a Java application by using the TransportClient.
I have successfully tested connected to a cluster running locally.
Now we have set up a remote cluster in the EC2-Cloud. Accessing it via REST intefaces work, also Kibana works.
I can run my application on the Elasticsearch Node directly successfully.
However when I try to connect remotely from another host, the log indicates that the connection succeeds, but then immediately fails with "An established connection was aborted by the software in your host machine".
I have verified that both server and client run the same version of Elasticsearch. Also the firewall configuration should allow communication on port 9300 as this is also needed for the cluster-nodes to communicate between each other.

My simple test looks like this:
Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "cluster-name")
.build();
logger.info("Creating client");
try (final TransportClient client = new TransportClient(settings)) {
logger.info("Setting adress to " + host + ":" + port);
client.addTransportAddress(new InetSocketTransportAddress(host, port));
logger.info("Having: " + client.connectedNodes());
BulkRequestBuilder bulkRequest = client.prepareBulk();
String json= "{ id: \"12345678\", value: \"value\" }";
bulkRequest.add(client.prepareIndex(INDEX, TYPE, "12345678").
setSource(json));
BulkResponse bulkResponse = bulkRequest.execute().actionGet();
if (bulkResponse.hasFailures()) {
logger.info("Could not write bulk: " + bulkResponse.buildFailureMessage());
} else {
logger.info("Wrote");
}
}
I also tried to verify some common things like cluster-name not set and others.
Also when I use a completely different port, I get a timeout as expected, not this error-message. So the port is definitely behaving different.
Where would I start to look? Can this still be a firewall issue where connections are dropped only after a short while instead of being rejected immediately?
With more testing I actually found out that a company-firewall was interfering in a strange way. When I run the same client-code on a machine outside the company-netowrk, it works fine.
I have written a JAXMPPClient.java program which uses tigase.jaxmpp.j2se.Jaxmpp 3.0.0
I have the following .jar files in my build path
jaxmpp-core-3.0.0
jaxmpp-j2se-3.0.0
and folder jaxmpp-all-3.0.0 containing many .jar files. The JAXMPPClient.java is as follows
Jaxmpp conn = new Jaxmpp();
conn.getConnectionConfiguration().setConnectionType(
ConnectionType.socket);
conn.getConnectionConfiguration().setDomain(IP_ADDRESS_OF_XMPP_SERVER);
conn.getConnectionConfiguration().setPort(PORT_NUMBER_OF_XMPP_SERVER);
conn.getConnectionConfiguration().setUserJID(FROM_USERID + "#" +
IP_ADDRESS_OF_XMPP_SERVER);
conn.getConnectionConfiguration().setUserPassword(FROM_PASSWORD);
String s = tigase.jaxmpp.j2se.connectors.socket.
SocketConnector.HOSTNAME_VERIFIER_DISABLED_KEY
conn.getSessionObject().setProperty(s, Boolean.TRUE);
try {
System.out.println("Before login");
conn.login();
System.out.println("After login");
} catch (final JaxmppException e) {
e.printStackTrace();
}
I am getting
