Opening a pdf document in a new window on click of commandLink in ADF

Question

Hi,
I am having a command link in my page and on click of that i am calling a webservice and getting the contents as bytes and writing the contents to the response outputstream. And i followed the below given steps. Everything works fine and i am getting the PDF displayed in new window. But i am getting a pop up blocker issue in IE and Firefox. Is there any workaround for that?
1: open a dialog , and get url of servlet
<af:commandButton text="Dialog Report" id="cbdialogReport"
action="#{ReportBean.cbdialogReport_action}"
useWindow="true" windowHeight="1000"
windowWidth="1100"/>
public String cbdialogReport_action() {
try {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext =
facesContext.getExternalContext();
HttpServletRequest request = (HttpServletRequest)externalContext.getRequest();
String strUrl = request.getRequestURL() + "";
int iPosition = strUrl.indexOf("/faces/");
strUrl = strUrl.substring(0,iPosition+6) + "/doreport";
this.reportURL = strUrl;
System.out.println("strUrl=" + strUrl);
//System.out.println("request.getRequestURI()= " + request.getRequestURI());
return "dialog:ReportDialog";
} catch (Exception ex) {
System.out.println(ex);
return null;

3: create a serlet
package com.pansoft.myerp.servlet;
import com.pansoft.myerp.view.Function;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.sql.Connection;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.*;
import javax.servlet.http.*;
import net.sf.jasperreports.engine.JasperRunManager;
public class doReport extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=UTF-8";
public void init(ServletConfig config) throws ServletException {
super.init(config);
/**Process the HTTP doGet request.
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
try
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext =
facesContext.getExternalContext();
//String strUrl = request.getRequestURL() + "";
//System.out.println("URL: " + strUrl);
response.setContentType("application/pdf");
response.addHeader("Content-Type", "application/pdf");
//response.setHeader("Content-Type", "application/pdf");
//response.addHeader("Content-Disposition", "inline;filename=Report.pdf");
Function function = new Function();
Connection conn = function.getCurrentConnection();
OutputStream outputStream = response.getOutputStream();
InputStream reportStream = externalContext.getResourceAsStream("/Report/rptChar.jasper");
JasperRunManager.runReportToPdfStream(reportStream, outputStream, null, conn);
outputStream.flush();
outputStream.close();
//facesContext.responseComplete();
}catch(Exception ex) {
System.out.println("doGet():" + ex);

I think you can't anything do about it if your popup blocker prevents the page to open.
Some such blockers allow to add white lists of url which are allowed to open popups.
