Hii,
I have created a hello world program. I used the code given in the programming help page. Created a HelloWorld class and HelloTask class. The driver and nodes are started properly after that it is saying the error as follows. i am putting my code for HelloWorld as follows
package test.hello;
import java.util.*;
import org.apache.log4j.Logger;
import org.jppf.JPPFException;
import org.jppf.client.JPPFClient;
import org.jppf.server.JPPFStats;
import org.jppf.server.protocol.JPPFTask;
import org.jppf.task.storage.*;
import org.jppf.utils.*;
public class HelloWorld
{
static Logger log = Logger.getLogger(HelloWorld.class);
private static JPPFClient jppfClient = null;
public static void main(String args[])
{
JPPFClient client=new JPPFClient();
List<JPPFTask> tasks = new ArrayList<JPPFTask>();
tasks.add(new HelloTask());
try {
// execute tasks
List<JPPFTask> results = client.submit(tasks, null);
JPPFStats stats = client.requestStatistics();
System.out.println("End statistics :\n"+stats.toString());
} catch (Exception e) {
e.printStackTrace();
}
}
}
HellowTask.java is as follows.
package test.hello;
import org.jppf.server.protocol.JPPFTask;
public class HelloTask extends JPPFTask {
public void run() {
setResult("Hello World");
}
}
