Java Selenium "findElement" doesnt find an existing object

After my problem was solved yesterday (see link below), new problems have opened up.
First, the solution to the above problem works only for the IE. When I try chrome or firefox with the same code to feed (except, of course, the driver) I get back the error message as at the beginning (before I downgraded the IEDriverServer). see link.
Eclipse Java Selenium failed to connect to localhost
Secondly. does not happen when I use the findelement function. Error message "unable to find e
lement". however, this element is there. here the page that should be controlled.

this problem is already frequently requested but unfortunately the answers do not help me. one solution was (as the findelement is faster than the browser) to install the following delay. driver.manage (). timeouts (). implicitlyWait (5, TimeUnit.SECONDS);
another solution was to search for id or xpath instead of name (that's why name and id are listed below as findelement). so far without success. none of the mentioned keys is entered in a field (password and first name, etc., I have already tried).
Here are the articles that come closest to my problem but have not helped me.
No such element exception | Internet explorer.
Same CSS Slector Not Working in Internet Explorer but works in firefox
anyway. the IE will open, but no other browser and no element will be filled. here code and error message.

Thanks again.

If you do Web Interface tests with Java + Selenium, I advise you to use the NoraUi Open Source Framework.
This Framework manage IE webdriver, Chrome webdriver and FF webdriver.

When ran on IE Probably //*[#id="lastName"] doesn't quite give you the exact element you want to work with. Instead when Can you try giving Xpath like below
//*[#id="lastName"]//following-sibling::div"

Unable to create primary index on couchbase using groovy script

I am not able to Create primary index on couchbase using groovy script. Below are the lines of code I used:-
#Grab('com.couchbase.client:java-client:2.2.6')
import java.util.concurrent.CountDownLatch;
import com.couchbase.client.java.Bucket;
import com.couchbase.client.java.Cluster;
import com.couchbase.client.java.CouchbaseCluster;
import com.couchbase.client.java.document.JsonDocument;
import com.couchbase.client.java.document.json.JsonObject;
import com.couchbase.client.java.CouchbaseCluster
import com.couchbase.client.java.query.N1qlQuery;
import com.couchbase.client.java.query.N1qlQueryResult;
import com.couchbase.client.java.query.N1qlQueryRow;
import com.couchbase.client.java.query.SimpleN1qlQuery;
import com.couchbase.client.java.env.CouchbaseEnvironment;
import com.couchbase.client.java.env.DefaultCouchbaseEnvironment;
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder().connectTimeout(10000).build();
def cluster = CouchbaseCluster.create(env, IPADDRESS);
def bucket = cluster.openBucket(BUCKET_NAME, BUCKET_PASSWORD);
log.info "Connection done"
String queryString = "CREATE PRIMARY INDEX `PrimInd` ON BUCKET_NAME"
bucket.query(N1qlQuery.simple(queryString))
log.info "Primary index created"
It gives me error as below :-
java.lang.RuntimeException: java.util.concurrent.TimeoutException at this line:-
bucket.query(N1qlQuery.simple(queryString))
Connection is being done properly and same query works in couchbase server. So, I think there is problem with my code.
Could you please help me on this?

In the Couchbase Java client, the query() method delegates to a Blocking API which uses JavaRx under the covers. The source code for the Blocking API states:
If an error happens inside the Observable, it will be raised
as an Exception. If the timeout kicks in, a TimeoutException nested in a RuntimeException is thrown to be fully compatible with the Observable.timeout(long, TimeUnit) behavior.
You're experiencing a TimeoutException nested in a RuntimeException, hence the root cause is that your query is timing out.
DefaultCouchbaseEnvironment defaults to a queryTimeout (the timeout used for N1qlQuery queries) of 75 milli-seconds. You can change this default with the environment builder:
def env = DefaultCouchbaseEnvironment.builder()
.connectTimeout(10000)
.queryTimeout(10000) // This is the query timeout
.build()

Connection made to Google Cloud SQL drops intermittently

I am using a Google Cloud SQL using Java-SQL connector. The issue I am facing is that the connection to database drops unexpectedly. While Googling I came across this question and tried the solution suggested in the same question.
In your console click the project, on the left side click Storage > CloudSQL then click on your database name. You will see an 'Edit' button on top. Click that and scroll down to Activation Policy, change it to Always On and then click save.
But I'm still facing the same issue. Fortunately I have been keeping the logs on Google App Engine and I have attached the snapshot of the exception that occurred while connecting to database.
Gist of the code that I've posted below is used to establish connection to the database.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.StringTokenizer;
import java.util.logging.Logger;
import com.google.appengine.api.utils.SystemProperty;
import static com.google.appengine.api.utils.SystemProperty.environment;
import static com.google.appengine.api.utils.SystemProperty.Environment.Value.Development;
import static com.google.appengine.api.utils.SystemProperty.Environment.Value.Production;
Connection con=null;
SystemProperty.Environment.Value env = environment.value();
if(env == Production)
{
System.out.println("Inside Production Phase");
// Load the class that provides the new "jdbc:google:mysql://" prefix.
Class.forName("com.mysql.jdbc.GoogleDriver");
url = "jdbc:google:mysql://<my-project-id>:<cloud-sql-instance>/<database-name>?user=<user-name>&password=<database-password>&useUnicode=true&characterEncoding=UTF-8";
}//if
else if(env == Development)
{
System.out.println("Inside Development Phase");
// This will load the MySQL driver, each DB has its own driver
Class.forName("com.mysql.jdbc.Driver");
url = "jdbc:mysql://127.0.0.1:3306/<database-name>?user=root";
}//else if
con = DriverManager.getConnection(url);
Is anyone facing the same problem, Please help.

Got a temporary fix, used following parameters while making connection to Google Cloud SQL
url = "jdbc:google:mysql://my-app:mysql2/project-name?user=root&password=password&autoReconnect=true&failOverReadOnly=false&maxReconnects=10";

Proper vertx versions for push notifications

I tried to run next code, but for 2.1.6 vertex library occurs io.vertx package not found problem.
Or if somebody have a small project with Java and JS code for this, give please a link.
Also I tried 3.x.x version, but it has no io.vertx method.
import io.vertx.core.AbstractVerticle;
import io.vertx.core.Vertx;
import io.vertx.core.eventbus.EventBus;
import io.vertx.core.http.HttpServer;
import org.vertx.java.core.sockjs.SockJSServer;
import org.vertx.java.core.sockjs.impl.DefaultSockJSServer;
//...
Vertx vertx = Vertx.newVertx();
EventBus eventBus = vertx.eventBus()
HttpServer server = vertx.createHttpServer();
JsonArray permitted = new JsonArray();
permitted.add(new JsonObject());
SockJSServer sockJSServer = new DefaultSockJSServer(vertx, server);
sockJSServer.bridge(new JsonObject().putString("prefix", "/pusher"), permitted, permitted);
server.listen(<some port>);

Vert.x versions 2.x used the org.vertx package, whereas the 3.x branch uses io.vertx, this is why you're running into problems.
For version 2 there are some examples regarding the event bus bridge:
https://github.com/vert-x/vertx-examples/tree/master/src/raw/java/eventbusbridge
And a lot of examples for Vert.x 3:
https://github.com/vert-x3/vertx-examples
So basically you should just stick to one of the versions and you should be fine.

spring social connectivity with Facebook and accessing user data

When i comment out this line:
Facebook facebook = new FacebookTemplate(accessToken);
It works fine.
Can someone suggest me the requisite. I am a newbie so please bear with me.

The URL you mentioned isn't really a tutorial as much as it is a reference. Admittedly, it gets a bit detailed and isn't very helpful for the new user. Duly noted...expect a new tutorial to be written as soon as I get a moment to do so.
Where did you get the value of accessToken? If you didn't get it via an OAuth2 "dance" with Facebook, then it's not going to work.
First, I see you creating a FacebookConnectionFactory to obtain an OAuth2Operations, through which you set a redirect URI, etc, etc..and then build an authorization URL for IMPLICIT grant. There are several things out of sorts there:
Facebook doesn't support IMPLICIT grant. It only supports authorization code grant and client token grant. Even so, with implicit grant and authorization code grant your app must redirect to Facebook (in a web browser) to obtain permission from the user. Once that's granted, then it will redirect back to your app...speaking of which...
The redirect URI you set is http://facebook.com. That should be the URL of your application where Facebook will redirect back to after authorization.
After all of that, you never even use the authorizeUrl...it's just in a String. It wouldn't work even if you did use it, for the reasons already mentioned, but the first 5 or so lines are all for nothing.
You create a ConnectionFactoryRegistry and register the FacebookConnectionFactory with it...but then you do nothing with the ConnectionFactoryRegistry. That's okay...you almost never need to do anything with it anyway, because it primarily exists as a helper to ConnectController.
There's simply no good way of obtaining a user-oriented access token without the redirect "dance". It's important to get permission from the user you'll be accessing Facebook on behalf of. If it were any easier than that, it'd be way too easy to create an app that spams Facebook and essentially ruins the experience for everyone.
The work of obtaining an access token via that redirect "dance" is handled automatically by the framework using ConnectController. Sure, you can do it yourself if you'd rather, but ConnectController will handle all of that for you.
For lack of a proper tutorial at the moment, I recommend that you have a look at https://github.com/spring-projects/spring-social-samples/tree/master/spring-social-showcase. Also, there's a Spring Boot-oriented version of it at https://github.com/spring-projects/spring-social-samples/tree/master/spring-social-showcase-boot that simplifies the configuration more (albeit, it relies on changes that aren't in an official Spring Boot release yet).
