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();
