With relation to session tracking,there is a doubt.Suppose there is a servlet A.I use it to retrieve some content of a table.In same i use out.println("") to introduce some radiobuttons.
I want to retrieve the value of them in servlet B.
How could i do that ?.req.getParameter () works but only on first turn.On closing browser window and again rexecuting it give nullvalues.How one could use session tracking.I feel there is no way because values have to be stored only at instance when Submit button is clicked .If any of u have a way please illustrate me.I will send the code if required.
