Hi,
Deprecated API means that you are using functions that almost will disappear
and new ones will come up (in new releases).  To avoid those warnings, you
should go to the API help and find out the new functions that replace the
ones you are using.  It is very important that you avoid using deprecated
functions, because in next releases of API you will get errors instead of
warnings.

Hope this helps,

Marco

I have figured out my previous problem: there was an HTML.class in the 
classes directory, so there were two versions of the same class file 
competing for attention.  When I erased the one in the classes directory, 
then the com/wrox/util version was accessed.

But after compiling, I came across another message that I can't explain:

-----------------------------
Note: ShoppingCart.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
-----------------------------

This is really a warning since ShoppingCart.class does compile, but I 
don't understand why the warning exist nor know what it means.  When I do 
as they ask, I get more warnings (but no errors) that I also don't 
understand.

-----------------------------
ShoppingCart.java:21: warning: getValue(java.lang.String) in 
javax.servlet.http.
HttpSession has been deprecated
        Integer itemCount = (Integer) session.getValue("itemCount");
                                              ^
-----------------------------

The bottom line is that I am able to compile this file and get it to work, 
but not without a warning.  Can anyone describe deprecation to me and how 
I might get the warnings to go away?
