How to programmatically do JSF internal page forwa

问题:

How to do JSF internal page forward programatically in managed bean, on some condition (like whenever an exception occurs)? I do not want to change the URL while forwarding to other page.

Right now I redirect to another page programmatically using this, but this changes the URL.

FacesContext.getCurrentInstance().getExternalContext().redirect();

回答1:

Try this:

public void forward(){
    String uri = "destination.xhtml";
    FacesContext.getCurrentInstance().getExternalContext().dispatch(uri);
}

回答2:

You can do using

   FacesContext.getCurrentInstance().getViewRoot().setViewId("your target view id");
   FacesContext.getCurrentInstance().renderResponse();   

or you can use

   FacesContext.getCurrentInstance().responseComplete();  

Hope this helps.
