Java Glassfish Applet

I moved an app from JBoss to **Glassfish** but an **Applet** fails to work now. ? The **Applet** downloads and starts up, but fails to retrieves data. ? We coded the **Applet** to retrieve data by invoking a JSP which returns pipe delimited data to the **Applet**, rather than accessing the database directly.

This trick worked fine with JBoss, but with **Glassfish** even though the **Applet** assembles the URL perfectly and invokes it, the server behaves as if nothing happened. ? **Glassfish**'s access log has NO record of the request. ? Why would this behave differently for **Glassfish** vs JBoss?

The **Applet** code invoking the request looks like this:

...

URL url = new URL("[[url removed, login to view]**appletQuery**.jsp?querystring=select%20patientID%20from%20patient%20where%20lastname='Smith'][1]");

BufferedReader input = new BufferedReader(new InputStreamReader([url removed, login to view]() ) );

Vector buffer = new Vector();

String line;

while ((line = [url removed, login to view]()) != null) [url removed, login to view](line);

[url removed, login to view]();

Launching of the **Applet** looks like this from JSP:

<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"

? ? ? ? alt="Your browser understands the <**APPLET**> tag but isn't running the **applet**, for some reason."

? ? ? ? </noembed>

? ? ? ? </embed>

</object>

The debug output shows a valid URL is generated and invoked, but nothing happens. ? If we copy/paste the URL into the browser it runs fine, so we know the URL is good and we know the User session is good.

Does **Glassfish** have some sort of setting that would prevent an **Applet** from submitting a Request like this? ? I don't recall any such setting for JBoss and this has always worked for JBoss.
