Why can't you use the href, provide your PDF location to href, it will work but that PDF link should be accessible to your web. – lakshitha madushan May 14 '20 at 18:14

@lakshithamadushan since it is a server location, it cannot be accessible to provide as href. Example: tomcat\\temp – Diya May 14 '20 at 18:18

There are different ways to do it, if you are using servlets you can write the right MIME type into the response and write the PDF to the servlet stream
Something like:
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("application/pdf;charset=UTF-8");
response.addHeader("Content-Disposition", "inline; filename=" + "cities.pdf");
ServletOutputStream out = response.getOutputStream();
InputStream inputStream = null;
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
inputStream = new FileInputStream("sourcePath_of_pdf.pdf");
byte[] buffer = new byte[1024];
baos = new ByteArrayOutputStream();
int bytesRead;
while ((bytesRead = inputStream.read(buffer)) != -1) {
baos.write(buffer, 0, bytesRead);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
baos.writeTo(out);
}
