Re: idl to java

i take example little change it

FUNCTION helloworld::INIT,title
    self.title=title
    self->MakeCurrent
   RETURN, 1
END

PRO helloworld__define
   struct = {helloworld, $
      inherits IDLitDirectWindow, $
      title:'' $
   }
END

pro main
  a=OBJ_NEW('helloworld','from idl')
  a->DRAWPLOT
end

PRO helloworld::DRAWPLOT
  x=indgen(201)*0.1
  y=sin(x)
  plot,x,y,TITLE=self.title
END

then i run IDLEXBR_ASSISTANT procedure. I combines ex****t different
properties and methods
created java file and make class file.
Then create java file and class file from it

package helloworld;
im****t com.idl.javaidl.*;
public class helloworld_example extends helloworld
implements JIDLOutputListener
{
   private helloworld hwObj;

   // Constructor
   public helloworld_example() {
      hwObj = new helloworld();
      hwObj.createObject();
      hwObj.addIDLOutputListener(this);
      hwObj.executeString("print, 'Hello World'");
   }

   // implement JIDLOutputListener
   public void IDLoutput(JIDLObjectI obj, String sMessage) {
      System.out.println("IDL: "+sMessage);
   }

   public static void main(String[] argv) {
      helloworld_example example = new helloworld_example();
	example.DRAWPLOT();
   }
}


so ...when i run i crush my JDK 1.6 :(((

so how ex****t graphics to Java ?

Thanks
