        org.apache.commons.httpclient.HttpClient client = new org.apache.commons.httpclient.HttpClient();
       // client.getHttpConnectionManager().getParams().setConnectionTimeout(50000);
        int status = client.executeMethod(filePost);
        if (status == HttpStatus.SC_OK) {
            System.out.println("Upload complete, response=" + filePost.getResponseBodyAsString());
        } else {
            System.out.println("Upload failed, response=" + HttpStatus.getStatusText(status));

        }
    } catch (Exception ex) {

The do_upload handler is probably looking for the file under the name file, but you're not adding a part by that name.

You need the 3 parameter constructor to set both the name and the filename:

new FilePart("file", targetFile.getName(), targetFile)

Or was the other part the attempt to set the part name? If so, then:

Part[] parts = {
    new FilePart("userfile", targetFile.getName(), targetFile)
};
