We have the following scenario. From page 'A' we download an applet.Then we open page 'B' from 'A' through window.open. Page 'B' downloads another applet - is it possible for this applet to invoke a method on the packaged applet from page 'A'. If not,is there any other better way to achieve this? Page 'B' is not modifiable .Page 'A' simply needs to download a 'listener' library on to the client machine,which can be called on/notified by the applet downloaded by page 'A'.
