Re: Scope levels for beans

[BMIROW@xxxxxxx]

In a servlet you set attributes which are your objects.  You can attach these 
objects to different scopes depending on their need.  So you may have objects 
that are just for the current request, you would create them in the servet like 
request.setAttribute("myData", data), then send out the jsp page.  In the jsp 
page the tag would look like <jsp:useBean id="myData" class="com.my.data" 
scope="request" />.  It now looks for the data in the request object and 
disappears when you submit the form, if you put scope as session it would not 
find it.  You may want to keep data for the entire sesssion, such as name.  
Then in the servlet you would say session.setAttribute("lastName", lName"), the 
in the jsp page you would say <jsp:useBean id="lastName" 
class="com.lang.String" scope="session" /> , now this data is always available 
throughout the entire session.
