Opening a Document (.doc, .xls, .pdf) in the browser using an action

Question

Hello
I´m using JavaScript to open a document in the browser using the property Onclick from Command Button: onclick="#{backing_archivos.rutaArchivo}"
and in the backing_archivos.rutaArchivo I have the String window.open("file://c://tmp/document.pdf", "title page", "top=100, left=100")
but the browser doesn't open anything.
What can I do?
Thank.

You can do an external file by using a stream and and the response object. I have this in a backing bean, and it gets called with a command button.
public String runQCReport_action()
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("PromotionRequestQCReport");
Object result = operationBinding.execute();
FileInputStream bis = null;
ServletOutputStream bos = null;
FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();
response.setContentType("application/pdf");
response.setHeader("Content-disposition","inline=filename=file.pdf");
try {
File fileName = new File("applications/reports/output/PromotionRequestQCReport.pdf");
bis = new FileInputStream(fileName.getAbsolutePath());
bos = response.getOutputStream();
byte[] buff = new byte[2048];
int bytesRead;
while (-1 !=(bytesRead = bis.read(buff,0,buff.length)))
bos.write(buff,0,bytesRead);
//response.getOutputStream().write(yourdata[]);
response.getOutputStream().flush();
response.getOutputStream().close();
context.responseComplete();
catch (IOException e) {
e.printStackTrace();
return null;
}
