mongoDB async driver java - unable to connect with authentication - mongodb

Recently we've updated our mongoDB with port 35489 and also with authentication and roles to the database.
I've granted readWrite and readWriteAnyDatabase roles for a user and can successfully connect from our c# coding from mentioning it from the web.config
My web.config:
<add key="MongoConnectionString" value="mongodb://readWriteUser:********#192.168.1.225:35489/admin" />
Now, my problem is I'm uanble to connect to mongoDB from java async driver and it is throwing an exception like
Exception
Exception in monitor thread while connecting to server localhost:35489 com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName='AdminAllDatabases', source='admin', password=, mechanismProperties={}} at com.mongodb.connection.SaslAuthenticator.authenticate(SaslAuthenticator.java:61) at com.mongodb.connection.DefaultAuthenticator.authenticate(DefaultAuthenticator.java:32) at com.mongodb.connection.InternalStreamConnectionInitializer.authenticateAll(InternalStreamConnectionInitializer.java:99) at com.mongodb.connection.InternalStreamConnectionInitializer.initialize(InternalStreamConnectionInitializer.java:44) at com.mongodb.connection.InternalStreamConnection.open(InternalStreamConnection.java:115) at com.mongodb.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:127) at java.lang.Thread.run(Unknown Source) Caused by: com.mongodb.MongoCommandException: Command failed with error 18: 'Authentication failed.' on server localhost:35489.

My async java driver code:
public static final String DEFAULT_URI = "mongodb://readWriteUser:******#localhost:35489/";
public static synchronized ConnectionString getConnectionString()
{
if (connectionString == null)
{
connectionString = new ConnectionString(DEFAULT_URI);
}
return connectionString;
}
public static synchronized MongoClient getMongoClient()
{
if (mongoClient == null)
{
mongoClient = MongoClients.create(getConnectionString());
}
return mongoClient;
}
we've tried with both localhost and ip address, but nothing seems to work.
Can anyone suggest me the right way to do this?

Hazelcast need to be connected as client in the existing cluster instead of member

The changes which I made in server side:
#Bean(name = {"hazelcast"})
public HazelcastInstance hazelcastInstance() {
ClientConfig clientConfig = new ClientConfig();
clientConfig.getGroupConfig().setName(integrationSettings.getHazelcastClusterGroupName())
.setPassword(integrationSettings.getHazelcastClusterGroupPass());
final ClientNetworkConfig clientNetworkConfig = new ClientNetworkConfig();
clientNetworkConfig.addAddress("127.0.0.1:6701");
clientConfig.setNetworkConfig(clientNetworkConfig);
clientConfig.setInstanceName("INTEGRATION_INSTANCE");
final String hazelcastEnterpriseLicenseKey = null;
if (hazelcastEnterpriseLicenseKey != null) {
clientConfig.setLicenseKey(hazelcastEnterpriseLicenseKey);
}
return HazelcastClient.newHazelcastClient(clientConfig);
}
I will be getting my groupname and password from my property file.
My client side code:
ClientConfig clientConfig = new ClientConfig();
clientConfig.getGroupConfig().setName(hazelcastGroupName).setPassword(hazelcastGroupPwd);
clientConfig.getNetworkConfig().addAddress(serverAddress);
hazelcastInstance = HazelcastClient.newHazelcastClient(clientConfig);
My error log:

I need to connect my hazelcast as a client, but this bean exception is failing the deployments. Is there is any other way of doing it?
Looking at your code you are creating "Hazelcast-Client" on the server side and Client Side. In the server side code , please create a hazelcast ServerMember instance by passing "Config" object and not "ClientConfig" more like
#Bean
public HazelcastInstance hazelcastInstance() throws Exception {
Config cfg = new Config();
...
...
HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
return instance;
}
The the Hazelcast-client can connect to the Hazelcast ServerMember. You also need to ensure the ServerMember is started before client can connect to it.

java.net.SocketTimeoutException: connect timed out when connecting to postgresql using jdbc

We are planning to switch DB from Oracle to PostgreSQL. After creating tables, I am about to load actual data into PostgreSQL tables. In order to do it, I connect to db using JDBC. It gives me error like below.
Connection Failed! Check output console
org.postgresql.util.PSQLException: The connection attempt failed.

At first I thought that data loading may take time and could cause this kind of problem, but I tested with following JDBC connection java. It still returns same error like above.
public class JDBCExample {
public static void main(String[] argv) {
System.out.println("-------- PostgreSQL "
+ "JDBC Connection Testing ------------");
try {
Class.forName("org.postgresql.Driver");
} catch (ClassNotFoundException e) {
System.out.println("Where is your PostgreSQL JDBC Driver? "
+ "Include in your library path!");
e.printStackTrace();
return;
}
System.out.println("PostgreSQL JDBC Driver Registered!");
Connection connection = null;
try {
connection = DriverManager.getConnection(
"jdbc:postgresql://aaa.bbb.ccc.ddd:5432/test", "tom",
"secret");
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
}
catch (Exception e) {
e.printStackTrace();
}
if (connection != null) {
System.out.println("You made it, take control your database now!");
} else {
System.out.println("Failed to make connection!");
}
}
}
In this case, what should I check first? There is some log file recording these errors in Postgresql? Is this something related with firewall? I even do not know our coporate has firewall? Could you give some guidance for this issue?

Mongo db authentication failure in java code does not go to catch block

I am trying to write code where mongo DB authentication is tested.
However when authentication fails the code does not reach to the catch block.
Here is the code :
MongoClient client = null;
try {
List<MongoCredential> credentials = new ArrayList<MongoCredential>();
credentials.add(
MongoCredential.createScramSha1Credential(
"abc",
"test",
"abc#123".toCharArray()
)
);
client = new MongoClient(host,credentials, MongoClientOptions
.builder().connectionsPerHost(20)
.threadsAllowedToBlockForConnectionMultiplier(15)
.connectTimeout(5000)
.writeConcern(WriteConcern.ACKNOWLEDGED).build());
} catch (Exception e) {
client = new MongoClient(host, MongoClientOptions
.builder().connectionsPerHost(20)
.threadsAllowedToBlockForConnectionMultiplier(15)
.connectTimeout(5000)
.writeConcern(WriteConcern.ACKNOWLEDGED).build());
// e.printStackTrace();
}
client.getDatabase("admin").runCommand(new Document("ping",1));
com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='abc', source='test', password=<hidden>, mechanismProperties={}}
at com.mongodb.connection.SaslAuthenticator.authenticate(SaslAuthenticator.java:61)

at com.mongodb.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:128)
at java.lang.Thread.run(Unknown Source)
This code never falls through into the catch block and runs the line just after the catch block.
Can you tell me how to handle this situation.

Its failing because of proxy setting or -Djava.net.useSystemProxies=true or because of cloud?
public class HibernateUtil {
private final static SessionFactory sessionFactory;
//private static final SessionFactory sessionFactory = buildSessionFactory();
static{
try {
sessionFactory = new Configuration().configure("/com/singtel/mi/utils/hibernate.cfg.xml").buildSessionFactory();
} catch (Exception e) {
System.err.println("Seesion Factory Creation Failed---> "+e);
throw new ExceptionInInitializerError();
}
}
public static SessionFactory getSessionFactory(){
return sessionFactory;
}
}
I am not able to get root cause for this.

Not able to invoke remote method in RMI communication

I am trying to execute one RMI program but i am getting exception when i try to call the remote method from RMI client program.
Server program:
import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;
public class Hello extends UnicastRemoteObject implements HelloInterface {
private String message;
public Hello() throws RemoteException{
int port=1024;
Registry registry;
try{
registry = LocateRegistry.createRegistry(port);
registry.rebind("samplermi", this);
System.out.println ("Server started and listening on port " + port);
}
catch(RemoteException e){
System.out.println("remote exception"+ e);
}
}
public String sayHi (String name) throws RemoteException {
message = "Hi .. Welcome " + name;
return message;
}
public static void main(String args[]){
try{
Hello serverObj = new Hello();
}
catch (Exception e){
e.printStackTrace();
System.exit(1);
}
}
}
Client Program:
registry=LocateRegistry.getRegistry(serverAddress,serverPort);
if(registry !=null){
String[] availRemoteServices = registry.list();
for(int i=0;i<availRemoteServices.length;i++){

System.out.println("calling remote method!");
// call the remote method
welcomeMsg = rmiServer.sayHi(text);
System.out.println("Message from server: " + welcomeMsg);
I am getting connection exception only at the time of calling the remote method sayHI. It works fine for lookup and listing the service name.

Note: The same program is working correctly when running server in solaris and client from windows. It is not working only when running server in AIX and client from windows.
Kindly can someone help in resolving this issue. I have been trying to fix this issue since 2 days but no use. Please help me!!
This is covered in Item A.1 of the RMI FAQ.
Run rmiregistry.exe before running Hello.class, it solved my problem.
RMi Working on the default port 1099. So no need to create the port.. If you are using default port number then exception may not be fired. and program may work properly.
