Need help understanding using data types with session.setAttribute & session.getAttribute

I'm learning jsp slowly and painfully so please forgive my newbie question...

In one page I'm trying to set a session variable. The second line here blows up.

'<% char schoolMode=''a'';
session.setAttribute("schMode", schMode); %>

And in another I try to access the variable and it blows up as well.
<% char schMode=(char)session.getAttribute("schMode"); %>

Thanks a bunch.

It is a typo in your session.setAttribute. It should be
session.setAttribute("schMode",schoolMode);

IT IS

'<% char schoolMode=''a'';
session.setAttribute("schMode", schoolMode); %>
OR simply
<% session.setAttribute("schMode","a");%>

TO ACCESS FIRST/second ONE ,

<% String schMode=session.getAttribute("schMode").toString(); %>

Is there a way to store a char value in the session? I will be going directly into a switch statement, which if I understand correctly only works with char or byte values.

How do I store the various data types in the session? It seems klunky to convert everything to string and back.

Thanks

Session should able to store Objects by default.

You may need to check the type of object store before you do the conversion.

use:

session.getAttribute("myobject").getClass()

><% char schMode=(char)session.getAttribute("schMode"); %>
and you must un-box (which will done automatically in java 1.5).
<% char schMode=((Character)session.getAttribute("schMode")).charValue(); %>
