  8.     </applet>
  9.     <script language="javascript" type="text/javascript">
  10.         var VERSION_REQUIRED = 150;
  11.         var javaVersion;
  12.         try { javaVersion = document.getElementById("CheckApplet").getVersion(); alert(javaVersion);} catch(e){ javaVersion = 0;}
  13.         if( javaVersion < VERSION_REQUIRED ){
  14.             if(javaVersion==0){
  15.                 alert(" It seems your browser does not support Java - Javascript communication.\n Continue at own risk...");
  16.             }
  17.             else
  18.             {            
  19.                 var t=confirm("You must go to the java download page to get the latest JavaPlugin...\nMinimal Version :"+VERSION_REQUIRED);
  20.                 if(t){window.open("http://java.sun.com/javase/downloads/index.jsp","","status=1,toolbar=1,width=600,height=480");}
  21.             }
