R help - Sep 2006 - Rserve and bibase

Hi 
   
  I am using Rserve for R2.3.1.
  every time after I load Biobase library, a new Graphics window  frame pops up.
Could any onw know how can avoid it.
   
  Best
  Saeede 
   
  class testReserve {
    public static void main(String[] args) {
    RServeConnection rsCon = null;
    Rconnection c = null;
    Process proc = null;
      try {
      Runtime rt = Runtime.getRuntime();
      proc = rt.exec(generalMetaData.rserveDir);
      try {
        c = new Rconnection();
        c._eval("library(grDevices)");
//        c._eval("graphics.off()");
        c._eval("postscript()");
        //load library
        c._eval("library(tools)");
        System.out.println(" load library tools");
        c._eval(" postscript('foo2.ps')");
        c._eval(" library(Biobase)");
        c._eval("graphics.off()");
        System.out.println(" load library Biobase");
       
        }
      catch (RSrvException ex1) {
        System.out.println(ex1.getMessage());
      }
      }
    catch (Exception e) {
      System.out.print("cannot run rserve");
    }
    //end of testing
    }
}
