I am crating a cron scheduler for which i am using the following code:-
import org.quartz.CronScheduleBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.ScheduleBuilder;
public class CronSched {
public static void main(String[] args) throws SchedulerException {
System.out.println("Started");
JobDetail job = JobBuilder.newJob(CronJob.class).build();
Trigger t1 = TriggerBuilder.newTrigger().withIdentity("MAILER").withSchedule(CronScheduleBuilder.cronSchedule("0 33 2 1/1 * ? *")).build();
Scheduler sc = StdSchedulerFactory.getDefaultScheduler();
sc.start();
sc.scheduleJob(job,t1);
}
}
and I am compiling teh following code in terminal with the following statement:-
javac -cp ".:/home/aditya/CronSched/lib/quartz-2.2.3.jar: /home/aditya/CronSched/lib/slf4j-api-1.7.25.jar: /home/aditya/CronSched/lib/slf4j-simple-1.7.25.jar: " CronSched.java
and on running the code I am using the following statement:-
java CronSched
and I am getting the following error:-
Error: A JNI error has occurred, please check your installation and try again

What to Do?
You have to add all necessaries jars to your runtime classpath.
java -cp "quartz-2.2.3.jar:...." CronSched

I was trying to understand the working of ExtentReports and wrote 2 simple classes one where I am initializing the extent report variables and the test class where I am using, please see the below classes
package TestProperty;
import org.testng.annotations.BeforeClass;
import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.reporter.ExtentSparkReporter;
public class CheckReport {
ExtentSparkReporter spark = new ExtentSparkReporter("C:\\Users\\jq2870\\eclipse-workspace\\TestJava Project\\Reports\\extentreports.html");
protected ExtentReports extent = new ExtentReports();
#BeforeClass
public void setUp() {
extent.attachReporter(spark);
}
}
and the class where I am using the report var is
import org.testng.annotations.Test;
import com.aventstack.extentreports.ExtentTest;
import TestProperty.CheckReport;
public class NewTest extends CheckReport{
ExtentTest test = extent.createTest("CreateUser");
#Test
public void f() {
test.info("This is a test class");
}
}
and I am trying to run this by right click on the class and run and testNG test in eclipse but getting this issue

Can anyone tell me why this error is coming?
ExtentReports include also FreeMarker jar that you need to have in classpath
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.30</version>
</dependency>

Ok, i have found the answer. The problem was that i have not all the libraries included, i add:
documents4j-util-all-1.0.3
documents4j-util-standalone-1.0.3
And it finally works
I'm trying to parse a bit of JSON in Java by following this tutorial. Because it mentions nothing about org.apache.commons.io.IOUtils other than it imports it, I figured all it was used for it to convert an InputStream into a String. I have my own code for that, so I omitted it. Here is my code:
import java.io.*;
import java.io.InputStream;
import java.net.*;
import java.util.Scanner;
import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
public class Net {
static String returnParsedIp() throws UnsupportedEncodingException, MalformedURLException, IOException {
String url = "http://httpbin.org/ip";
URLConnection connection = new URL(url).openConnection();
connection.setRequestProperty("Accept-Charset", "UTF-8");
InputStream response = connection.getInputStream();
String responseString = new Scanner(response,"UTF-8").useDelimiter("\\A").next();
//return responseString;
JSONObject json = (JSONObject) JSONSerializer.toJSON(responseString);
String Ip = json.getString("origin");
return Ip;
}
}
I then call the method from my main class with:
public class DDNS {
public static void main(String[] args) throws Exception {
String Ip = Net.returnParsedIp();
System.out.println(Ip);
}
}
However, it throws the following error:

Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)
Any help is appreciated.
Either you don't have the Apache Commons lang and io JARs in your CLASSPATH or you have the wrong version.
Caused by: java.lang.ClassNotFoundException: org.apache.commons.lang.exception.NestableRuntimeException
This is Java 101. You need all the dependencies in the CLASSPATH in order to compile and run.
You have to add the commons-lang jar in yout project
I'm having trouble running this sample code for the gdata java library:

You need to add guava to your Java Build-Patproject: http://code.google.com/p/guava-libraries/
