ShowTable of Contents

Place data into a variable


sessionScope.put("key", "some string value");
var a = new Array();
a.push("value1");
a.push("value2");
sessionScope.put("anotherkey", a);

Get data


var v = sessionscope.get("key");

Scope types

applicationScope


Are visible for all users of one application. Expires some time after the last user used an applicationScope variable.
That means applicationScope variables are NOT persistent forever. But they can be used for caching stuff for all users.

sessionScope


Is valid through the session of the current user. A user session expires after some time of inactivity. Uses don't have access to the sessionScope variables of other users.

requestScope


Is valid through one request of the current user. That includes refreshing of a page.

viewScope


Is visible for views on the current page only. Useful for transporting a search query to a view.
