Accessing Web Session variable in a Java class

Hi,

I want to know if there is a way to use session.getAttribute("string") in a java class.

Actually that java class makes an xml message from the information entered on the online web application and sends to another coldfusion application. I have to add one more element that exists in one of the jsp pages to that xml message.

For this, i am trying to make that value available at session level and want to pull it from the session while making the xml message in the java class.

Is this possible? If not can anyone suggest me how i can incorporate that value ( like some orderID ) which is available in one of the jsp pages in the xml message?

Thanks,
Phani
