Strategie for Applets to save data on client

[burshy -]

Hi,
<p>I have the following problem. An Applet should save data to the harddisk
of a client.
<br>Hence it is not allowed to do that  it calls a Servlet and passes
the Data to it where they are stored.
<br>In Step 2 it calls:
<p>.getAppletContext().showDocument(URL of  Servlet, "FrameName");
<p>Problem:
<br>if an Exception occoures, only the Browser will be notified. Not the
Applet as I want to! So I can't react in the Applet.
<p>Can anybody help me?
<p>Best Regards,
<br>UlliD
