In this program, we connect to the servlet’s URL of the application FileUploadSpringMVC (see this tutorial: Upload files with Spring MVC): Multipart.addFilePart("fileUpload", uploadFile2) Multipart.addFilePart("fileUpload", uploadFile1) Multipart.addFormField("keywords", "Java,upload,Spring") Multipart.addFormField("description", "Cool Pictures") Multipart.addHeaderField("User-Agent", "CodeJava") MultipartUtility multipart = new MultipartUtility(requestURL, charset) * This program demonstrates a usage of the MultipartUtility class.įile uploadFile1 = new File("e:/Test/PIC1.JPG") įile uploadFile2 = new File("e:/Test/PIC2.JPG")

Code Java Client program to upload file:Since the MultipartUtility class abstracts all the detailed implementation, a usage example would be pretty simple as shown in the following program: package

Now let’s take a look at an example of how to use this utility class.

Private static final String LINE_FEED = "\r\n" * This utility class provides an abstraction layer for sending multipart HTTP Code Java multipart utility class:We build the utility class called MultipartUtility with the following code: package Let’s examine this interesting solution now. In this post, you will learn how to code a Java client program that upload files to a web server programmatically.In the article Upload file to servlet without using HTML form, we discussed how to fire an HTTP POST request to transfer a file to a server – but that request’s content type is not of multipart/form-data, so it may not work with the servers which handle multipart request and it requires both client and server are implemented in Java.To overcome that limitation, in this article, we are going to discuss a different solution for uploading files from a Java client to any web server in a programmatic way, without using upload form in HTML code.
