Hi guyz. I have a problem in retrieving data rfrom my database and displaying them on the screen. I have written a java beans class, a DAO, controller class and the view part(jsp). I use a custom tag to call the controller class which should invoke the DAO but then to my surprise the controller class shows that the getAttributes method has no value. I have the setAttribute method in the controller class in the following mode...

....
....
protected void handleHttpRequest(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.getSession().setAttribute("id", kvitt );
}


I then call the doStartTag method in the same class in the following mode...

...
...
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
if (getRequest().getAttribute("id") != null) {

kvitt = (Kvittering)getRequest().getAttribute("id");
.....
.......

the kvitt instance always returns null. Anyone knows why this is so??

i think i found the problem .

in part of setting , you use session ,
Code:
req.getSession().setAttribute("id", kvitt );



in the part of getting you use request .
Code:
if (getRequest().getAttribute("id") != null) {

I have tried to use session but the problem is still there. Nothing is printed on the browser. Any other alternative would be welcome
