Open PDF with commandLink

Question

Hi,
I'm trying to generate and open a PDF file in a new window, but i'm having problems showing the file. My main doubt is what to return from the Action method:
The button:
<h:commandLink styleClass="commandLink" id="link1" target="_blank" action="#{pc_MyClass.doLink1Action}">
Open File                                   
</h:commandLink>The method doLink1Action:
StringBuffer sbFilename = new StringBuffer();
               sbFilename.append("filename_");
               sbFilename.append(System.currentTimeMillis());
               sbFilename.append(".pdf");
               resp.setContentType("application/x-download");
               StringBuffer sbContentDispValue = new StringBuffer();
               sbContentDispValue.append("attachment");
               sbContentDispValue.append("; filename=");
               sbContentDispValue.append(sbFilename);
               resp.setHeader(
                    "Content-disposition",
                    sbContentDispValue.toString());
               resp.setContentLength(baosPDF.size());
               ServletOutputStream sos = resp.getOutputStream();
               baosPDF.writeTo(sos);
               sos.flush();
               getFacesContext().responseComplete();It generates the PDF, but i don't know how to open it.
Hope you can help me.
P.S.: I need a solution that doesn't require invoking servlets.

I had encountered this problem earlier. Check your server log if you see an IllegalStateException.
