Image file upload using jsp and servlet in java (2023)

Image file upload using jsp and servlet in java

Here’s a sample of utilising Java’s JSP and Servlet to upload a picture:

Make a JSP that has a form with a “file” input field: html

The following code should be copied:!DOCTYPE html> html> head> meta charset=”UTF-8″> title>File Upload Example

End Title End Head Body Start H1

Here’s a Sample Form That Uploads a File Using the FileUploadServlet Method and the multipart/form-data Encoding: h1>
To upload a file, please choose it here: input type=”file” name=”file”>br>br> input type=”submit” value=”Upload”> /form> /body> /html>
Start by making a Servlet class to accept files:
java
To clone a programme
The code begins by importing the necessary packages: import java.io.File; import java.io.IOException; import java.io.PrintWriter; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http

Class FileUploadServlet HttpServlet> has the following public interface: @WebServlet(“/FileUploadServlet”) private static final long serialVersionUID = 1L;

protected PrintWriter out = response.getWriter(); String savePath = “C:uploads”; void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException; response.setContentType(“text/html;charset=UTF-8”); To alter this to your desired route, edit: /

The code is as follows: file fileSaveDir = new File(savePath); if (!fileSaveDir.exists()) fileSaveDir.mkdir();

If (String fileName)!= “”; for (Part part: request.getParts()) extract filename Part.write(savePath + File.separator + fileName), FileName(part).

It’s been successfully uploaded: out.println(“File: ” + fileName + ” uploaded to ” + savePath);

inaccessible String extractFileName (Part part) It goes like this: String contentDisp = part.getHeader(“content-disposition”); String[] items = contentDisp.split(“;”);
for (String s : items) (String s : items) in case (s.trim().startsWith(“filename”)) To get back “,” you would do the following: return s.substring(s.indexOf(“=”) + 2, s.length() – 1); return “”;
Start the programme and load the JSP page. Click the “Upload” button once you’ve chosen a file to send. Upon successful upload, a screen message will appear with the file’s name and the path to where it was saved.
Keep in mind that this is only an example and should not be utilised in a real world setting without some tweaks, such as adding error handling and security measures.
