ClassNotFount exception while creating MarkLogic client in Java WebService

I've used wsdl file to generate Java classes, but I can't create MarkLogic client in endpoint (it throws NoClassFound exception).
Endpoint code:
/**
* Please modify this class to meet your needs
* This class is not complete
*/
package yu.ac.ns.ftn.informatika.ws.hello;
import java.util.logging.Logger;
import yu.ac.ns.ftn.informatika.ws.hello.types.RequestMissType;
import com.marklogic.client.DatabaseClient;
import com.marklogic.client.DatabaseClientFactory;
import com.marklogic.client.DatabaseClientFactory.Authentication;
/**
* This class was generated by Apache CXF 2.1.3
* Fri Jan 23 09:13:16 CET 2009
* Generated source version: 2.1.3
*
*/
#javax.ejb.Stateless
#javax.jws.WebService(
serviceName = "HelloDocumentService",
portName = "HelloDocumentPort",
targetNamespace = "http://informatika.ftn.ns.ac.yu/ws/hello",
endpointInterface = "yu.ac.ns.ftn.informatika.ws.hello.HelloDocument")
public class HelloDocumentImpl implements HelloDocument {
private static final Logger LOG =
Logger.getLogger(HelloDocumentImpl.class.getName());
/* (non-Javadoc)
* #see
yu.ac.ns.ftn.informatika.ws.hello.HelloDocument#sayHelloMiss
(yu.ac.ns.ftn.informatika.ws.hello.types.RequestMissType requestMiss )*
*/
public java.lang.String sayHelloMiss(RequestMissType requestMiss) {
LOG.info("Executing operation sayHelloMiss");
System.out.println(requestMiss);
DatabaseClient client =
DatabaseClientFactory.newClient(
"localhost", 8000,
new DatabaseClientFactory.DigestAuthContext("user1", "user1"));
System.out.println(client);
return "Hello miss " + requestMiss.getFirstName() + " " + requestMiss.getLastName();
}
}
Client code:
package yu.ac.ns.ftn.informatika.ws.client;
import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import yu.ac.ns.ftn.informatika.ws.hello.HelloDocument;
import yu.ac.ns.ftn.informatika.ws.hello.HelloDocumentService;
import yu.ac.ns.ftn.informatika.ws.hello.types.RequestMissType;
public class HelloClient {
public void testIt1() {
try {
URL wsdlLocation = new URL("http://localhost:8080/vezbe-wsdl-ws/services/HelloDocument?wsdl");
QName serviceName = new QName("http://informatika.ftn.ns.ac.yu/ws/hello", "HelloDocumentService");
QName portName = new QName("http://informatika.ftn.ns.ac.yu/ws/hello", "HelloDocumentPort");
Service service = Service.create(wsdlLocation, serviceName);
HelloDocument hello = service.getPort(portName, HelloDocument.class);
RequestMissType request = new RequestMissType();
request.setFirstName("Dijana");
request.setLastName("Ninkovic");
String response = hello.sayHelloMiss(request);
System.out.println("Response from WS: " + response);
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
HelloClient client = new HelloClient();
client.testIt1();
}
}
If I delete code for creating MarkLogic client everything works fine.

It looks like you are missing some jars while deploying your application.
Please make sure you have your build.xml configuration set so it deploys all of marklogic jars you need.

<classes dir="${bin.dir}">

Good luck!

Shiro using spring gives " Shiro INI configuration was either not found or discovered to be empty/unconfigured."

I was able to get shiro running with shiro.ini and spring but I want to use shiro annotations and so i was trying to go for shiro-spring without ini file. but this is giving me hard time,

Take a look at the 1.4+ release, the Spring integration has been updated (for Spring, and Spring Boot).
But for your specific problem, it looks like you are trying to use a the EnvironmentLoaderListener. When using Spring, you will need to let Spring handle the lifecycle of loading your components.
For an example see: https://github.com/apache/shiro/blob/1.3.x/samples/spring-hibernate/src/main/webapp/WEB-INF/web.xml

My simple ghostdriver program is not running?

Let me tell you, I'm completely new by using GhostDriver
I successfully download PhantomJSand i've set my path into environment variable, now i'm trying to run this simple program:

import org.openqa.selenium.WebDriver;

private static final By HELP_LINK = By.xpath("//a[text() = 'Help']");
#BeforeClass
private void initialize() {
driver = new PhantomJSDriver();
driver.navigate().to("http://www.seleniumhq.org/");
}
#Test
public void verifySomething() {
driver.findElement(ABOUT_TAB).click();
assertThat(driver.findElement(ROADMAP_LINK).isDisplayed(), is(true));
assertThat(driver.findElements(HELP_LINK).isEmpty(), is(true));
}
#AfterClass
private void quit() {
driver.quit();
}
}
I tried to run it, But it's saying:

Please help :(
HELP WOULD BE APPRECIATED!!
UPDATED
After downloading selenium-common.jar, I'm getting this error:
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the phantomjs.binary.path capability/system property/PATH variable; for more information, see https://github.com/ariya/phantomjs/wiki. The latest version can be downloaded from http://phantomjs.org/download.html

You need to set the path to your phantomDriver executable like so:
DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true); // enabled by default
caps.setCapability(
PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
"path/to/your/phantomjs.exe"
);
driver = new PhantomJSDriver(caps);
driver.navigate().to("http://www.seleniumhq.org/");

WriteExcel test = new WriteExcel();
test.setOutputFile("d:/test.xls");
test.write();
System.out.println("Please check the result file under d:/test.xls");
}
}
The method writeTestFile() from the WriteExcel class works fine when tested in a local standalone project.
The servlet itself also works when the method writeTestFile() is not called.
Could someone clarify why I'm getting the exceptions?
Also is there a fix or workaround?

Try this: double click on the server, click on "Open launch configuration", go to Classpath tab and under User Entries add the jar.

That means that tomcat can't find the Jena libraries. Make sure you have all the right jars in the right place.

You need to copy each of the *.jar files from $JENA/lib (where $JENA is the directory you installed your local installation of Jena into) to the WEB-INF/lib directory of your servlet application.

just copy the jena jars declared on the build path project to the lib directory of tomcat, in my case it is located at
C:\Apache Software Foundation\Tomcat 6.0\lib
