Answer 1

According to this page in the ZK documentation, the desktopScope object is a Map maintained by the ZK framework that holds variables shared at a particular scoping level; i.e. the desktop level.

Now I can't figure out what the "wchi" framework is ... or whether that is just a typo. But if you are simply converting your code to plain JSP / JSTL code, then you need to figure out an appropriate JSP / JSTL scope (the standard ones are "page", "session", "request" and "application") and then set your variable from Java, depending on the scope:

• "request" scope variables are set using Request.setAttribute
• "session" scope variables are set using Session.setAttribute
• "application" scope variables are setting ServletContext.setAttribute
• "page" scope variables cannot be set outside of the page JSP.

Note that the "desktop" scope is a purely ZK concept, and you are going to need to figure out a non-ZK way of achieving .... whatever it is that those variables achieve. The "session" scope might be the most appropriate.
