I'd like my desktop java application to be able to upload a file to a web form that accepts files.

<form action="multFileUpload.php" method="post" enctype="multipart/form-data" name="form1" id="form1">
<input name="image1" type="file" id="image1" size="50" /></td>
<input name="image2" type="file" id="image2" size="50" /></td>
</form>

Anyone have any source on how to do this?

Thanks, but..
I'm not looking for a servlet, or a servlet to parse an incoming file request.
I'm looking for the java code that would upload a file to the html script above.

The links above either talk about servlets, or how to receive the file being upoaded.

objects:
you're last post helped.
but how do I specify which file I'm uploading?  I'm uploading two specific image files, image1 and image2.  The code snipped only shows a single file.
I would have expected that I need some sort of &image1=Body of image 1?


public class PostAFile {
    private static String url =
         "http://localhost:8080/HttpServerSideApp/GetRequest.jsp";

    public static void main(String[] args) throws IOException {
        HttpClient client = new HttpClient();
        PostMethod postMethod = new PostMethod(url);

        client.setConnectionTimeout(8000);

        // Send any XML file as the body of the POST request
        File f = new File("students.xml");
        System.out.println("File Length = " + f.length());

        postMethod.setRequestBody(new FileInputStream(f));
        postMethod.setRequestHeader("Content-type",
            "text/xml; charset=ISO-8859-1");

        int statusCode1 = client.executeMethod(postMethod);

        System.out.println("statusLine>>>" + postMethod.getStatusLine());
        postMethod.releaseConnection();
    }
}

You need to use a multioart upload if you want to send more than one file at a time. Have a look at the JUpload applet - you can use code from that

Use a MultipartPostMethod

        HttpClient client = new HttpClient();
        MultipartPostMethod mPost = new MultipartPostMethod(url);
        client.setConnectionTimeout(8000);

        // Send any XML file as the body of the POST request
        File f1 = new File("students.xml");
        File f2 = new File("academy.xml");
        File f3 = new File("academyRules.xml");

        System.out.println("File1 Length = " + f1.length());
        System.out.println("File2 Length = " + f2.length());
        System.out.println("File3 Length = " + f3.length());

        mPost.addParameter(f1.getName(), f1);
        mPost.addParameter(f2.getName(), f2);
        mPost.addParameter(f3.getName(), f3);

        int statusCode1 = client.executeMethod(mPost);
