Question

How can I open a link from bean?I will open something like http://www.google.de.It should open the directory.

Answer 1

You can’t open a link from a bean. A link requires enduser interaction.

Rather tell the browser directly to send a new GET request on the given URL. You can use ExternalContext#redirect() for this.

public void action() throws IOException {
    FacesContext.getCurrentInstance().getExternalContext().redirect("http://www.google.de");
}

This makes however no sense if that’s the sole action of the bean. Rather use <h:outputLink> or just <a> instead of <h:commandLink action="#{bean.action}"> or something.

<h:outputLink value="http://www.google.de">link</h:outputLink>
<a href="http://www.google.de">link</a>
