Session Values Getting Destroyed

[kiranbg]

We are generating an Unique Number and storing the same in a variable called temp and adding it to the Session. We are now passing this variable temp in a URL to another server say Server-2 for transactions.
Now from Server-2 the same value will be sent in the URL to Server1.

The value from Server-2 will be compared to the value in the Server-1 which is in Session.

When the value is tried to retrive from the session ,the session is getting Destroyed.

This is what the code I have written


if(session.getAttribute("USER1")!=null)
{
String userFromSession = session.getAttribute("USER1").toString();


String user1 = request.getParameter("user1");


Can you please suggest a solution for this.

Hi Kiran!

I don't know if you have already the sloution of your problem, but if not, here it is:

You have to cast the object, which is placed in the session scope to your desired type. The Method toString() is not the right way.

It should look like this:

String userFromSession = (String) session.getAttribute("USER1");

This could be the browser's behaviour, I faced the issue recently.

I noticed cookie settings :

Browser's settings (Firefox) :
- Keep cookies : until they expired

Tomcat's settings :
- Cookie generated by tomcat with name JSESSIONID, has attribute
"Expires : at the end of session' .


For browser, when you visit URL2 , you leave URL1 actually , and it means - "End of session for URL1" .

You can solve the problem in 2 ways :

1) set browser's setting : Keep cookies : until I close browser

2) always send to URL2 also session id to get back to URL1 .
In other words, your URL1 to return must look like

URL1;jsessionid=XXXXXXXXXXXXXXX

always .
