Sometimes you want to perofrm some validations and based on the result, forward to other ADF pages.

You can follow one of these following approches.

Approach I
/* Forward to page "myPage.jspx" */
FacesContext fc = FacesContext.getCurrentInstance();
UIViewRoot viewRoot = fc.getApplication().getViewHandler().createView(fc, "/myPage.jspx");
fc.setViewRoot(viewRoot);
fc.renderResponse();

Approach II
/* Forward to the navigation rule "mypage" */
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().getNavigationHandler().handleNavigation(fc, null, "mypage");

Approach III
/* Redirect to page myPage.jspx */
FacesContext.getCurrentInstance().getExternalContext().redirect(/myPage.jspx);
