RE: what is switch action & forwardAction in struts

A Forward Action is a standard Action forwards the request to the context-relative URI(JSP/Servlet) specified by the parameter property of the associated ActionMapping.To configure the use of the Forward Action in your struts-config.xml file, create an entry like this: which will forward control to the context-relative URI specified by the parameter attribute.A Switch Action is a standard Action that switches to a new module and then forwards control to a URI within the new module. Switch Action elements are used only in applications consisting of more than one 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. Action Mapping in struts-config.xml looks as follows.To link to a page in another module, use a URI as followshttp://localhost:8080/mywebapp/toModule.do?prefix=/myModule&page=/index.jspThe Swtich Action, first switch to myModule and forward to index.jsp in myModule.
