带有 target ="_ blank" 属性的< h:commandLink/> 怎么样:

<h:commandLink action="#{bean.action}" target="_blank" value="Open document"/>

在您的bean中:

public void action() {
   try {
       FacesContext.getCurrentInstance().getExternalContext()
            .redirect("page2.xhtml");
   } catch (IOException ex) {
       // do something here
   }
}

用目标网址替换 page2.xhtml .
