Calling Servlets from JSF

Another point I struggled with is calling servlets from JSF. Here is a simple example.

This is the bean which is called from .jsp page

import javax.faces.context.FacesContext;

public class ServletTest {

    public void doThis(){
    String url = "url of your servlet";
    FacesContext context = FacesContext.getCurrentInstance();
    try {
       context.getExternalContext().dispatch(url);
    }catch (Exception e) {
       e.printStackTrace();
    }
    finally{
       context.responseComplete();
    }
  }
}

This is the .jsp page

<f:view>
<h:form id="myForm">
<h:commandButton value="Do" action="#{ServletTest.doThis}" />
</h:form>
</f:view>
