I Have A Problem With A Bean Not Found In The Scope Of The Bean.

Over the past few weeks, some of our readers have come across the well known error message bean not found in usebean. This problem occurs for several reasons. Now we will discuss them.

You need the class aspect instead of the type attribute.

Bean Bean is equal to (Bean) pageContext.getAttribute("bean", PageContext.REQUEST_SCOPE);if (bob == null)    throw ServletException("new bean not found in scope");// use vegetables...

bean not found within scope usebean

Bean Bean is equal to (Bean) pageContext.getAttribute("bean", PageContext.REQUEST_SCOPE);if (bob == null) Bean is equivalent to new Bean();    pageContext.setAttribute("bean", bean, PageContext.REQUEST_SCOPE);// use bean...

If the site has worked before and never “suddenly” works, then the device means that something indicating that a bean is about to be placed in the area has stopped working. Set up a servlet that handles the match in doGet():

request the attribute .setAttribute("bean", new Bean());request.getRequestDispatcher("page.jsp").forward(request, response);

You may be specifying a JSP page URL on purpose instead of our own servlet URL. For example, if you want to disable direct access to JSP pages, just put them in /WEB-INF and redirect them instead.

    Thanks for the result, Surya Kant. Yes, it continues to work fine on my localhost, but correctly shows an internal server failure.

    I tried to scope the application, but I still get the same error. Could you please tell me how to solve your current problem.

    2 thingswhich you can try
    1.Insert import statement in JSP
    all yours 2.Check if your classpath contains an accessible put directory
    I hope this solves your problem
