Could could do it this way. Add a h:commandLink on a page pointing to an action method of your bean:

<h:commandLink value="download report" action="#{myBean.downloadReport}" />

In your bean you should generate your report and write it to the OutputStream of the response:

public class MyBean {

  public String downloadReport() {

    // get HttpServletResponse
    FacesContext context = FacesContext.getCurrentInstance();
    HttpServletResponse response = 
      (HttpServletResponse) context.getExternalContext().getResponse();

    // set correct content type
    response.setContentType("application/pdf");

    // get OutputStream
    OutputStream stream = response.getOutputStream();

    // TODO: generate PDF and write the report to this output stream 

    // mark response as completed
    context.responseComplete();
    return null;

  }
}
