I am using the example provided by @BalusC in the question. But I am getting an exception
java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided org.apache.catalina.connector.Request.parseParts(Request.java:2824) org.apache.catalina.connector.Request.getParts(Request.java:2792) org.apache.catalina.connector.Request.getPart(Request.java:2961) org.apache.catalina.connector.RequestFacade.getPart(RequestFacade.java:1105) com.example.JSPtest.upload.doPost(upload.java:36) jakarta.servlet.http.HttpServlet.service(HttpServlet.java:689) jakarta.servlet.http.HttpServlet.service(HttpServlet.java:770) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) This is what I have done.
<form action="upload" method="post" enctype="multipart/form-data"> <input type="text" name="description" /> <input type="file" name="file" /> <input type="submit" /> </form> static String URL = "localhost:3306/"; static String DATABASE_NAME = "DB"; static String USERNAME = "user"; static String PASSWORD = ""; @WebServlet("/upload") @MultipartConfig(maxFileSize = 16*1024*1024) public class UploadServlet extends HttpServlet { protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String description = request.getParameter("description"); // Retrieves <input type="text" name="description"> Part filePart = request.getPart("file"); // Retrieves <input type="file" name="file"> String fileName = Paths.get(filePart.getSubmittedFileName()).getFileName().toString(); // MSIE fix. InputStream fileContent = filePart.getInputStream(); // ... (do your job here) try { Class.forName("com.mysql.jdbc.Driver"); Connection con = DriverManager.getConnection("jdbc:mysql://" + URL + DATABASE_NAME, USERNAME, PASSWORD); PreparedStatement ps = con.prepareStatement("insert into data(image) values(?)"); ps.setBinaryStream(1, fileContent); int result = ps.executeUpdate(); } catch (Exception e) { e.printStackTrace(); } } } The data column is a blob. Note I have not used servlets as IntelliJ has an issue where it is not finding the java servlet class files.
Any help?
