How to access temp directory of the local machine

Question

I am working on an application in which I need to open attachments. I need to click on the "Open" button and open a pdf file. The way I do it, is by getting the content from the Server and writing it to a location on the temp directory.

However when I try to access this service from a remote machine, http://myserverIP:port/openMyAttachment, it accesses the temp directory of myserverIP instead of the local machine. It then opens the file on myserverIP.

I am using the following code to get the temp directory:

    String tmp = System.getProperty("java.io.tmpdir");      
    JFileChooser fc = new JFileChooser();
    FileSystemView fsv = fc.getFileSystemView();
    File f = fsv.getDefaultDirectory();
    String dir = f.getAbsolutePath();
    String strDirectory = "temp~" + f.separator;

Can someone please share your thoughts? How can I get to access the temp directory on teh local machine and write the file to the local machine?

You're trying to do too much on the server. If you have a Java program running locally, then it should be showing the JFileChooser, then fetching the file, writing it to a local temp space, and displaying it. The only thing the server should do is provide an InputStream to get the file contents from. If you change your server to have a getAttachment query (or something) instead of the openMyAttachment query that just serves back a pdf file. Then you should be able to fetch it with a URLConnection and complete the work on the local computer.
