Hi all, I am using a java class/bean class in JSP page as below. My JSP page has the following : <jsp:useBean id="id1" class="BeansMultiLang.MultilangPriceHandler" /> String login = request.getParameter("login"); boolean flag = id1.checkLogin(login); if(flag) do this else do that ***************************************** Now, I want to confirm one thing : Whether above code is similar to as BeansMultiLang.MultilangPriceHandler = new BeansMultiLang.MultilangPriceHandler(); (Like in simple java or servlet class) What I mean to say is whether new object of above class is made every time this jsp page is visited or this object is called only once & shared by all JSP page calls. Though the methods are synchronized in BeansMultiLang.MultilangPriceHandler class but still this java class has some class variables which are changed everytime its methods are called(From JSP page).One variable may be changed by 2 separate methods. If object is not created for every page, I might be in trouble, because wrong conclusions can be done then. If new object is created everytime then its fine. Can anybody help me out & confirm How beans/java classes objects are used & interpreted in JSP pages. I am in the mid of project & stuck up. Please help.......... Manoj
You have a choice to control the lifetime of the bean object by means of the "scope" attribute used in the jsp:useBean tag. The default is scope="page" - gives you a new object with every request, only visible inside the JSP Other values allowed are: scope="request" - like page but can be forwarded scope="session" - saved in session scope="application" - shared by all Bill
