public class SwitchAction

extends Action

A standard Action that switches to a new module and then forwards control to a URI (specified in a number of possible ways) within the new module.

Valid request parameters for this Action are:

• page - Module-relative URI (beginning with "/") to which control should be forwarded after switching.
• prefix - The module prefix (beginning with "/") of the module to which control should be switched. Use a zero-length string for the default module. The appropriate ModuleConfig object will be stored as a request attribute, so any subsequent logic will assume the new module.
