I am creating a dummy JSON and trying to query it. I am doing that using JAVA. The code is as follows :-
import static com.couchbase.client.java.query.Select.select;
import static com.couchbase.client.java.query.dsl.Expression.s;
import static com.couchbase.client.java.query.dsl.Expression.x;
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.env.CouchbaseEnvironment;
import com.couchbase.client.java.env.DefaultCouchbaseEnvironment;
import com.couchbase.client.java.query.Query;
import com.couchbase.client.java.query.Statement;
public class AccessData {
public static void main(String[] args) {
CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
.queryEnabled(true)
.build();
Cluster cluster = CouchbaseCluster.create(env, "127.0.0.1");
Bucket bucket = cluster.openBucket("default", "");
JsonObject testDataBlog = JsonObject.create().put("type", "blog").put("data", "blablabla");
JsonObject testDataComment = JsonObject.create().put("type", "comment").put("data", "ho hey");
bucket.upsert(JsonDocument.create("testDp4Blog", testDataBlog));
bucket.upsert(JsonDocument.create("testDp4Comment", testDataComment));
Statement statement = select("*").from("default").where(x("type").eq(s("blog")));
Query createIndex = Query.simple("CREATE PRIMARY INDEX ON default");
bucket.query(createIndex);
Statement withPlaceholders = select("*").from("default").where(x("type").eq(x("$1")));
}
}
On executing the above code, I am getting the following error :-

Any clues to fix it ?
It looks like you're using pretty outdated versions of the server and the SDK, and developer preview versions!
I'd strongly advise you to do a fresh clean install of Couchbase Server 4.1.0 and to use the Java SDK in it latest version, 2.2.7. A few things will have changed:
you won't need the queryEnabled(true) when configuring the environment
Query has been renamed N1qlQuery
The error you get indicates that when the client tries to connect on localhost, nothing answers (at least on port 11210). Can you check that the node is correctly up in the web console?
Once again, prefer installing Couchbase with 4.1.0. If you don't have any particular data to keep in your current instance, do a full reinstall (by removing the current installation first. see here).

Trying to run 2 separate Vertx applications. They both connect to the same database. I am getting the following bind exception.
I am only using http server on one of the projects thus don't think the following even matters. But tried it anyway with no difference. The error seems to stem from the attempt to connect to DB or so I think based on the exception. How can I overcome this to be able to run both projects same time? Please advice. Thanks.
Passing in the following as an environment variable doesn't make a diff as expected:
http.port=8095
Neither does setting port in following way makes a diff.
int port = 8095;
DeploymentOptions options = new DeploymentOptions().setConfig(new JsonObject().put("http.port", port));
vertx.deployVerticle("verticle.MyVerticle", options);

I am using httpclient-3.0 library to parse data to cloud. When I run the application on my local machine (Windows 10), it works fine and the data gets parsed to the server and I receive success response, but when I deployed it on our server which runs on Windows server 2012 R2, it throws below error. I have used the same JDK as well I tried many ways like adding -Djdk.tls.client.protocols="TLSv1,TLSv1.1,TLSv1.2" in my java.security jdk file, but still the issue is not resolved.
Here is my code
PostMethod post = new PostMethod(apiUrl);
post.setParameter("authtoken", authToken);
post.setParameter("dateFormat", dateTimeFormat);
post.setParameter("data", emloyeesAttendanceJsonArr.toString());
HttpClient httpclient = new HttpClient();
// Configuring proxy
httpclient.getHostConfiguration().setProxy("**.**.**.**", ****);
try {
long timeTrace = System.currentTimeMillis();
int result = httpclient.executeMethod(post);
System.out.println(">> HTTP Response status code: "+result);
System.out.println(">> Response Time: "+(System.currentTimeMillis() - timeTrace));
.......
.......
.......
}
I appreciate any quick help and guidelines.

The local proxy and the server proxy were different that is why it was running fine on my local machine but not on the server, once I changed the proxy to the specific proxy which server was using then the application was working fine.
As a newbie to MongoDB I'm trying to insert a simple document into my freshly installed mongoDB (v3.2.4). MongoDB Driver 3.2.2 is used.
Here my minimized code:
public <classname>()
{
public static final String COLLECTION_NAME = "logs";
MongoClient mongoClient = new MongoClient("<server-adress>");
MongoDatabase db = mongoClient.getDatabase("test");
Document data = new Document ();
data.append(<whatever>);
//...inserting more into document...
db.getCollection(COLLECTION_NAME).insertOne(data); //collection should be created new
mongoClient.close();
}
The programm is executing, but I'm getting the following errors (and informations) during execution:

The document is also not inserted.
When I'm commenting the line with the insertOne()-command, it disappears. So I assume it isnt' a problem with the connection, is that right?
I've some ideas:
Does it has something to do with asynchronity? I'd be suprized, I said nowhere that I don't want to execute it synchronous.
Are any permissions missing (because of this WritableServerSelector-Thing)?
Does it has to do with the "test"-database?
Are there problems with the stand-alone-mode of MongoDB? (I don't want to use replicasets.)
But for all these ideas I couldn't find real proofs...
(Please improve the question-title, I had no better idea...)
Solved it on my own.
I also should have mentioned, that I'm trying to connect from another machine to the MongoDB-instance. That is not allowed with the MongoDB-presets.
So I had to change in the /etc/mongod.conf File the value behind bindIp from 127.0.0.1 to 0.0.0.0.

I am trying to access several websites by using Selenium in Java. Occasionally, I get an UnreachableBrowserException. I have read many threads about this error but it seems like there are many different causes of the error. I get the error about 1% of the time when I attempt to access a new page and I cannot find any similarities between occurrences. I currently am using Firefox, however I have also tried Internet Explorer and experienced similar errors. I am only opening one page at a time and have tried using the same window and completely quitting the driver before trying to access another page and either way the error still occurs. It is important to note I do not always get this error sometimes my code can run without this occurring. Here is the error message:

How can I prevent this error or at least catch the error and deal with it effectively?
UnreachableBrowserExceptions can happen for multiple reasons - the most obvious is that the browser was closed, either in code or physically in the GUI, and then the code attempted to access it. Often, like in your case, they are caused by socket errors. This can mean, again, multiple things - your program tried to open too many sockets, it couldn't connect to a remote website, and others.
What I would suggest doing in a situation like this is waiting a short time, then retrying to see if the exception is still thrown. Sometimes these situations resolve themselves and your program can recover.
Here is some code to do that. It keeps retrying as long as the UnreachableBrowserException is thrown and the number of retries is below some limit that you set. If it hits the retry limit and the exception is still being thrown, it closes the browser and restarts it, resetting the retry count to 0. There is also a restart counter, to make sure that if for some reason restarting the browser doesn't help, you don't loop endlessly through running code -> exception -> wait -> retry -> hit retry limit, restart browser -> run code -> exception. Here, exceeding the restart limit (or successfully accessing the browser) will break out of the loop.
If you want more help, let me know.Hope this is helpful!

I am running a database that acts as the source for data to import into Solr. When I run the command: curl "http://localhost:8983/solr/dataimport?command=full-import&commit=true", the commit fails and the instance does a rollback. Can you help me to figure this out?

This is just a connection error, so check the data sources in the beginning of the data-config.xml file in Solr. It's probably just something simple like a bad URL, incorrect credentials, forgot to put the DB name in the URL, etc. Make sure you can ping the DB server from the Solr server.
The datasource tag should be something like this:
<dataSource type="JdbcDataSource"
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://database.server.com/database-name"
user="user"
password="pass"
name="datasource-name" />
And the entities in your data-config.xml should either have no datasource specified (if you only have one in the file) or should specify the name of the datasource you want to use if there are multiple.
Good luck!
