How to open a PDF file in a new tab - jsf

Question

I am working with JSF and I want to open a PDF file in a new tab when I click on a button.
XHTML
<p:commandButton onclick="this.form.target = '_blank'"
actionListener="#{managedBean.openFile(file)}"
ajax="false" />
Managed bean
public void openFile( File file ) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
BufferedInputStream input = null;
BufferedOutputStream output = null;
try {
// Open file.
input = new BufferedInputStream(new FileInputStream(file), 10240);
// Init servlet response.
response.reset();
// lire un fichier pdf
response.setHeader("Content-type", "application/pdf");
response.setContentLength((int)file.length());
response.setHeader("Content-disposition", "attachment; filename=" + node.getNomRepertoire());
response.setHeader("pragma", "public");
output = new BufferedOutputStream(response.getOutputStream(), 10240);
// Write file contents to response.
byte[] buffer = new byte[10240];
int length;
while ((length = input.read(buffer)) > 0) {
output.write(buffer, 0, length);
}
// Finalize task.
output.flush();
} finally {
// Gently close streams.
output.close();
input.close();
}
}
The problem is when I use this method it only downloads the file. For your information, I'm following this post: http://balusc.omnifaces.org/2006/05/pdf-handling.html

Answer 1

You should change
response.setHeader("Content-disposition", "attachment; filename=" + node.getNomRepertoire());
into
response.setHeader("Content-disposition", "inline; filename=" + node.getNomRepertoire());
So, use inline instead of attachment.
