I am new to JPPF and i had gone through the tutorial of jppf but i am not able to run a simple java program. i am running programs by copying them into JPPF Application template folder and adding the task to application runner. please someone tell me how to run a fresh program.

Thanks for replying,
Actually I am trying to implement an encryption algorithm using JPPF, so i am starting with a simple program lets say adding two numbers which is running on java perfectly now i changed the program to run on jppf as follows:
import org.jppf.server.protocol.JPPFTask;   
public class TemplateJPPFTask extends JPPFTask
{
   public void run()
   {
      
      System.out.println("Hello, this is the node executing a one vishal's template 2 JPPF task");
      int a = 56;
      int b=61;
      int c;
      c=a + b;
      System.out.println("addition of "  + a +  " and "  + b +" is "+ c);
      setResult("the execution of my templet was performed successfully");
         
   }
}

and i had already started JPPF node , Server. Now how i will run this code on jppf? 
please guide me i will really appreciate your help.

Hi,

Thanks for the clarification. Now all you need is to create an application that will create a job with one or more instances of your task, and submit this job to the grid using the JPPF client APIs.
You have an example of that in in the JPPF application template: the class org.jppf.application.template.TemplateApplicationRunner.
Basically the code boils down to something like this:

Code: [Select]

public class MyJPPFRunner {
  public static void main(String...ars) {
    JPPFClient jppfClient;
    try {
      // start a JPPF client
      jppfClient = new JPPFClient();
      // create a job
      JPPFJob job = new JPPFJob();
      job.addTask(new TemplateJPPFTask());
      // run the job on the grid
      List<JPPFTask> results = jppfClient.submit(job);
      // ... process the results ...
    } catch(Exception e) {
      e.printStackTrace();
    } finally {
      if (jppfClient != null) jppfClient.close();
    }
  }
}
I hope this helps.

Sincerely,
-Laurent
