If I use this line of code within a class which I call how can I use it in other parts of my web app? Like userInfo.firstName in a JSP.
UserInfo userInfo =new UserInfo(userfname);
My UserInfo class:
package com.ibm.drawinginquiry.rational;
publicclass UserInfo{
public String firstName;
public UserInfo(String fName){
firstName = fName;
}
}
I am not sure this is what I need. In the programming language I am used to I declare a variable to be public assign it a value and it is accessable throughout the entire session of the app.
So in my way of thinking.
I create a UserInfo class that accepts say one argument(fName) with a FirstName property. In a class that I call when a user logs on I create an object of the UserInfo class sending it the log on users firstname. Now I would expect to be able to get this property value at anytime and any where by using the userInfo.getFirstName() syntax.
This is not the case since I get cannot resolve userInfo everywhere except in the class where I created the userInfo object.

I understand what you want to do (at least I think so) and the singleton pattern is the answer to your question.

Ah. I thought that he had a web app where he had done that, and now he wanted to do something similar in a java application. But it looks like you are correct, and that I didn't understand the question.

First, a Java Server Page (JSP) is a Java servlet.

In the Web container of a Java web server, each invocation of a servlet creates a session (SessionContext).
If you want to share an object so that it is visible by all sessions, then you can store the object in the (ApplicationContext).

I think the OP wants to maintain user information, per user session, not globally.
I think that is correct. Please bare with me. I promise I wont stay ignorant forever. I need users to log on to the web app. Each user will fire a connection class that determines there authority to use various functions of the web app. I have classes, servlets, jsp's and what ever else I need to make this work.
The basics is an app used by an Engineering group to view, create and modify drawing data that resides on an AS400 database.
Say their authority is Guest. They need to only get and view data so my JSP would not show them modify or delete buttons.
The problem is the authority level was determined at log on and now they have moved through several servlets and JSP's.
Is this still one session? Or does each of the JSP's have its on session. If this is one session how do I get the session attributes from one JSP to another?
