How to foward to another JSP from an actionListener ActionEvent

有两种方法:

简单的方法是在commandlink中添加一个 action attribute  .然后你有一个actionListener 和 an action Attribute, 两个都是可行的.

但是你还可以使用下面的代码:

String viewId = "/edit.jsp"; FacesContext context = FacesContext.getCurrentInstance(); UIViewRoot view = context.getApplication().getViewHandler().createView(context, viewId); view.setViewId(viewId); context.setViewRoot(view); context.renderResponse(); 如何从java代码中重定向一个JSF页面 示例代码如下: public static void redirectPage(String szPage) {  FacesContext context = FacesContext.getCurrentInstance();  javax.faces.application.Application app = context.getApplication();  UIViewRoot view = app.getViewHandler().createView(context, szPage);  context.setViewRoot(view);  context.renderResponse(); }
