    need some advice for a good methodology to build my application


    hi all,

    I'm making my first web app under websphere + visual age.
    my web app is really simple : i have currencies and i must update the
    currency change rate each month. so i have 2 specific functions in my
    servlet :

    - search function: search for the good currency in the database
    - apply function : apply the changes and refresh the web page with the new
    values.

    I've done almost all work except something.
    here is my question : i don't know what is the best way to do, maybe you

    could help me :

    when I've executed the search function, how should i load the results of

    my search in the web page ?
    should i use variables in the jsp, call the search function in my servlet

    , put the values found in the variables of the jsp and then call the jsp

    to be refreshed from the servlet with the variables ? or is there a
    "cleaner" method to do ?

    I'm sorry for my coarse English,
    regards,
    Elise

    Elise,
    a standard way (MVC) to solve your problem is that:
    put your currency value in a javaBean (Model). The JavaBean can be stored
    in HTTP Session. Your JSP (View) can use the javaBean to display the new
    currency value.
