I have started using jena api and written a simple program like this

  package tutorial;  
  import com.hp.hpl.jena.rdf.model.Model;
  import com.hp.hpl.jena.rdf.model.ModelFactory;
  public class HelloRDFWorld {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    Model m=ModelFactory.createDefaultModel();

  }

 }

but i am getting this exception 

  Exception in thread "main" java.lang.UnsupportedClassVersionError: com/hp/hpl/jena/rdf/model/ModelFactory : Unsupported major.minor version 51.0

I know this is because of higher java version during compilation as compared to run time.But how to resolve that in eclipse

When I try to use 

sudo update-alternatives  java

it shows 

 only one config

  • I have already tried that it is not working for me – aditi rana May 14 '15 at 16:07
  • This question was indeed related to apache jena(simple java programs are running fine) thats why I had added it.Also I had tried other gien options given in the earlier post but nothing worked for me.I found the reason that apache jena required 1.7 version and I was using 1.6.Once I installed 1.7 and changed the version in window->pref->installed jre ,it started working for me – aditi rana May 14 '15 at 17:41
