Would use a Filter or Controller-Servlet to do this instead of a jsp myself,
but that's mostly a style issue. In any case, the code is the same wherever
it lives:
<%
ObjectInputStream ins = new
ObjectInputStream(request.getInputStream());
MyClass myObject = (MyClass)ins.readObject();
%>
Of course, the definition of MyClass visible to the webapp has to be the
same as it is to the Applet for this to work. Assuming that the definition
of MyClass is in the same jar as the Applet (say, applet.jar), then having
an identical copy of applet.jar in WEB-INF/lib should work.
