JSP全局Scriplet变量

Question

I am trying to create a java web application using JSP and script;ets. I am using netbeans, i have all my jsp files under web, and my .java files under src. Is there anyway, I can access an object created in one .jsp file in another .jsp. Any changes made in a any one of the .jsp files must be reflected in the others.

You can try session object to store created object in one jsp and access it in another jsp. This might work for you:

//Set object on one jsp:
<%
Hello hello = new Hello();
session.setAttribute("helloObject", hello);
%>

//Get object on second jsp:
<%
Hello helloObject = (Hello)session.getAttribute("helloObject");
%>
