Java在Adobe Reader中的客户端上打开pdf文件

Question

In Java Web Application, I have to open PDF file in client machine which is available in share that too without copying to client side. It should open in adobe reader in client side.

Answer 1

If the file is located on the client side, If he double clicks the file, it would open in the Adobe reader :-)

But the server can't open a file located on the client side. If the web application needs to open then the file needs to be present in the server readable location. You can write a servlet to open the PDF file.

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ServletOutputStream servletOutputStream = null;
BufferedInputStream bufferedInputStream = null;
BufferedOutputStream bufferedOutputStream = null;
try {

    // Public user guide
    String fileName = "MyFile.pdf";


    bufferedInputStream = new BufferedInputStream(new FileInputStream(fileName));

    byte[] data = new byte[bufferedInputStream.available()];
    bufferedInputStream.read(data);

    response.setContentType("application/pdf");
    servletOutputStream = response.getOutputStream();
    bufferedOutputStream = new BufferedOutputStream(servletOutputStream);
    bufferedOutputStream.write(data);

} catch (Exception e) {
    LOG.error(e);
} finally {

    if (bufferedInputStream != null) {
        bufferedInputStream.close();
    }

    if (bufferedOutputStream != null) {
        bufferedOutputStream.flush();
        bufferedOutputStream.close();
    }

    if (servletOutputStream != null) {
        servletOutputStream.flush();
        servletOutputStream.close();
    }
}
