How to fix Cloudant-client connection error - cloudant

I used cloudant-client-1.0.0.jar to make a test to check the connection to cloudant server as:
import com.cloudant.client.api.CloudantClient;
import com.cloudant.client.api.Database;
public class test {
private CloudantClient client=null;
public CloudantClient connect(){
client=new CloudantClient("xxx", "xxx", "xxx");
System.out.println("Connection successful! "+client.getBaseUri());
return client;
}
public Database getDb(String dbName){
Database db=connect().database(dbName, true);
System.out.println("Datase avaible - "+db.getDBUri());
return db;
}
public static void main(String[] args){
new test().getDb("_user");
}
}
However, the system shows errors:
Exception in thread "main"
java.lang.NoClassDefFoundError: org/apache/http/client/methods/HttpEntityEnclosingRequestBase
at connection.test.connect(test.java:13)

How to fix it?

You're missing a dependency for the library, Apache http client. However you should use Maven, gradle or a similar build tool which understands Maven repositories. You should also look at upgrading to 2.4.1, it contains numerous improvements and bug fixes.

How do I actually make Geb work with Grails 2.3.11?

Stumbled across Geb the other day. I'm on Grails 2.3.11. How do I actually install Geb correctly? I downloaded the jar files and included them but when I try to run my code I get ClassNotFoundException on org.openqa.selenium.WebDriverException
I'm using IntelliJ IDEA if that matters.
Libraries
Gebtest.groovy
package gebish
import geb.Browser
class Gebtest {
public static void main(String[] args) {
println "Hi!"
Browser.drive {
go "http://gebish.org"
assert title == "Geb - Very Groovy Browser Automation"
}
}
}

I also use Grails 2.3.11 and got GEB running. It's been a while, so I'm not sure what exactly is needed but here are some parts of my BuildConfig.groovy that might be relevant:
def gebVersion = "0.13.1"
def webdriverVersion = "2.53.1"
dependencies {

Google login gives error

I tried to implement google login in my project but it is giving me unknown host error after signing in with gmail username and password & then pressing the allow button. I have also kept android.playService.plus in build hint. Are other build hints necessary too? I didn't find proper documentation or blog to apply it as well.My code is as follow:
if (googleLogin.isNativeLoginSupported()) {
if (!googleLogin.isUserLoggedIn()) {
googleLogin.doLogin();
}
AccessToken at = googleLogin.getAccessToken();
System.out.println("token " + at.getToken()); // this value is null
} else {
if (!googleLogin.isUserLoggedIn()) {
googleLogin.doLogin();
System.out.println("not logged in : not native login");
}
}
googleLogin.setCallback(new LoginCallback() {
#Override
public void loginFailed(String errorMessage) {
Dialog.show("Login Faild", "Retry Login", "Retry", null);
google_signIn(res);
}
#Override
public void loginSuccessful() {
System.out.println("successfull");
new NewForm(res).show();
}
});

On the simulator we need to use web login as there is no native login and it uses a web page which might not look great.
On the device native login is used and should feel seamless. It's important to check devices for this sort of functionality as they behave very differently.

That generally means your web connection or DNS is problematic.
If the host isn't found networking can't really proceed.

I added trace and see that the connect call is failing. Am i doing anything wrong? any help would do. thanks in advance...
It's probably a network problem unrelated to JavaMail, e.g., a proxy or firewall between you and Gmail.
If you want to find out whether it's your code that's broken or the network that's broken, you can test using the code that comes with JavaMail. If the JavaMail code works, then you know there's something wrong with your code, and you can use the JavaMail code in the FAQ to improve your code.
If you discover that it's a network problem, the JavaMail FAQ also has tips for debugging it further.
