Hi I m putting a vector in a session on my first page which is a dynamic html generated by the output of a servlet like this HttpSessiom session = req.getSession(true); session.putValue("MyVector",obj); where Vector is declared at class level in this way Vector obj = new Vector(); If i try to retrive the vectors value in my second page by this way HttpSession ses = req.getSession(true); Vector obj = (Vector)ses.getValue("MyVector"); when i run my application first time it retrives the value of obj in second application as null but when i refresh the browser and again call the second application from first then it runs perfectly fine Can anyone suggest where I m going wrong? any views ?

from what I understand, the way you did it will only create a new session if one doesnt exist. So shouldnt be a problem, but its worth a try I suppose. I did the same thing using ArrayList and had no problem. I hope you find solution. [This message has been edited by Randall Twede (edited February 27, 2001).]
I'm willing to bet that you're running into browser caching. If you're using IE, try Internet Options -> Temporary Internet Files Settings -> Every visit to the page. If that works, add headers to your response to disable caching. - Peter
