my project Spring project is using java, jsp to develop the system, and each page will have it class
when the user login the system, they need to input id and password, after that the system will retrieve the user's Profile and set value into LOGIN class for example

login class {

private username;
public string getUsername {
return username;
}

public void setusername (string name){
this.username=name;
}

when the user go to another page, it will have it own class, may i know if I can get the username whenever the user is still login in system? when the username value will be discarded?
when user go to another page, can i still get username value?

my project Spring project

The question is about how to use the API for the Spring framework. It just happens that java is the connecting language. A knowledge of Spring is required for this project. If you have the API doc for what you are trying to do and have a java programming question about how to use it, post the API doc and your question.

Sorry, I do not know Spring or jsp.

Please edit your post and wrap your code with code tags:

[/code]

to get highlighting and preserve formatting.
