How to foward to another JSP from an actionListener ActionEvent
有兩種方法:
簡單的方法是在commandlink中添加一個 action attribute? .然后你有一個actionListener?和 an action Attribute, 兩個都是可行的.
但是你還可以使用下面的代碼:
String?viewId?=?"/edit.jsp";
FacesContext?context?=?FacesContext.getCurrentInstance();
UIViewRoot?view?=?context.getApplication().getViewHandler().createView(context,?viewId);
view.setViewId(viewId);
context.setViewRoot(view);
context.renderResponse();
如何從java代碼中重定向一個JSF頁面示例代碼如下:
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();
