usebean

This question already has an answer here : jsp:useBean scope (1 answer) Closed 3 years ago . I've got a forum where a user can register there details and this gets sent to a Servlet and then a Java bean. What I'm having trouble with is that I can't get the data to be displayed on another JSP page when the Java bean is requested. So CreateAccount.jsp allows the user to input into the forum.

However, the List interface doesn't have a setter, just an add() method. A workaround would be to wrap the list in a real javabean like so: public class ListBean { private List<Object> list = new ArrayList<Object>();
