redirection to another portlet

Hello,

I want to make a link in my XHTML that makes the redirection to another portlet.

Thanks

Hi Alex,
One way to do this is to use an actionListener on an h:commandLink. In your view.xhtml, the h:commandLink would look like this:

<h:commandlink value="yourLinkText" actionListener="#{yourBackingBean.redirect}" />

And in the java in YourBackingBean.java, the redirect() method would look like this:

public void redirect() {
		LiferayFacesContext liferayFacesContext = LiferayFacesContext.getInstance();
		ThemeDisplay themeDisplay = (ThemeDisplay) liferayFacesContext.getThemeDisplay();
		String portalURL = themeDisplay.getPortalURL();
		String redirect = portalURL + "/your/redirect/url";

		try {
			liferayFacesContext.getExternalContext().redirect(redirect);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

If you want to short-circuit the JSF-lifecycle so that validation and all phases after it are skipped, you can add immediate="true" to the h:commandLink as well.

To use the LiferayFacesContext you will need the liferay-faces-portal jar, and to use the ThemeDisplay you will need portal-service.

Hope that helps,
