This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
If a, for instance, enter Page1.jsp wich has a link to Page2.jsp I get a session object. Clicking on the link and moving to Page2.jsp gives me another session object (different sessionID). This render the session object useless, so I cannot use it for storage of session-scope variables.
The reason is that IceBrowser doesn't support cookies (another bugs are filled). See the docs for HttpServletResponse.encodeURL and use it in your links for session tracking.
