Variable evaluation order

No such variable: No variable Test defined.

The variables are evaluated in the following order:

  1. 'Preset' variables (or constants), as those listed on this page.
  2. 'Context' variables, as those set by plugins and tags.
  3. 'Property' variables, like those set in
  4. 'Page' variables, like those set using the "SET" directive.


WikiVariables are variables that are evaluated when a page is viewed.

The two types of WikiVariables are defined below.

Page Variables#

Starting with JSPWiki 2.2, you can use the "SET" directive to define a variable that exists only in the page.
For example:
  [{SET foo='bar'}]

creates you a variable called "foo", which has the value of "bar". You can access this value anywhere on your page by using the shorthand "[{$foo}]".

Pre-defined Variables#

Inserting JSPWiki properties#

You can also access some of the JSPWiki properties (that have been defined by the site maintainer) by using their property names directly. See SystemInfo for an example. Note that some properties might not be accessible due to security reasons.

You can also obtain some data from the JSPWiki Plugins.

Needs more info on how to set global variables in I cannot find how anywhere..
