Printing a PDF from JSF

Hello Everybody,

I have some procedure that, retrieves a pdf after some processing that incluyes DB queries, then after having the name of a PDF stored in the File System, I needto send a print command. How could I do it?

In the forums I have found that I can print the current page using JavaScript function window.print(), but how could I emule that using JSF, but Printing directly a pdf?

Thanks a lot,

bogotano

Printing a PDF directly is not possible. Why?

There is that JS-Method print(), but this has to be in a HTML document. Keep in mind that all actions, that required actions on client side, cannot be called directly but only per JS or s.th. like that.

You just can link on that PDF, but the user has to click print in the browsers's menu manually.

@arunz:The PDF is already there, he said. So creating the PDF is not the problem, but sending the print-command to the browser.

How can I get to read the PDF. I have a pdf in my filesystem I am unable to read it or display it on my page. Can you please let me know if you are able to get it to display on you page. I am using JSF for the portal and itext to create a pdf.Thanks in advance,dave

Well you must be having a link or button for printing the pdf doc.

So on click of the link/button, invoke an action method (say printPdf)of the controller .The method will look like this :

public void printPDF(ActionEvent event) {

// byte[] pdf = get ur pdf here...

FacesContext faces = FacesContext.getCurrentInstance();

HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();

response.setContentType("application/pdf");

response.setContentLength(pdf.length);

response.setHeader("Content-disposition", "inline");

response.setHeader("Cache-Control", "cache, must-revalidate");

response.setHeader("Pragma", "public");

try {

ServletOutputStream out = response.getOutputStream();

out.write(pdf);

} catch (IOException e) {

log.debug("IOException in viewPdf: " + e.toString());

}

StateManager stateManager = (StateManager) faces.getApplication().getStateManager();

stateManager.saveSerializedView(faces);

faces.responseComplete();

}

The pdf which you have generated using iText will be open up inline....I guess this would help...

Thanks,

Archan
