I create a context parameter that will be showed in a welcome page (a variable that contains a long name), then I tried in my computer and this work fine, I tried in other pc in the same network and work fine also but..., in other 2 pcs of my network the parameter not appear, it say "null" !
I check cookies (I think cookies is not the problem because it is a welcome page, not session required) and these are enabled.
Somebody know what is the problem???
PD: I am working with NetBeans and tested the web aplication in "explorer" and "firefox"
