For the servlet side, i tried to use Apache Commons FileUpload,downloading the specific jar files. However, the app is not working, it just does nothing. It seems that the code of request in servlet is unreachable. Since I include in the "action" part of form the name of the servlet, it should communicate with it. Here's the code I have on POST method of servlet till now.

			

			import java.io.*;
			

			import java.util.*;
			

			import javax.servlet.*;
			

			import javax.servlet.http.*;
			

			

			import org.apache.commons.fileupload.*;
			

			import org.apache.commons.fileupload.servlet.ServletFileUpload;
			

			import org.apache.commons.io.FilenameUtils;
			

			import org.apache.commons.lang.StringUtils;
			

			import org.apache.log4j.Logger;
			

			

			

			public void doPost(HttpServletRequest request, HttpServletResponse response) {
			

			if (ServletFileUpload.isMultipartContent(request)) {
			

			handleMultiPartContent(request);
			

			}
			

			}
			

			

			private void handleMultiPartContent(HttpServletRequest request) {
			

			

			ServletFileUpload upload = new ServletFileUpload();
			

			upload.setFileSizeMax(2097152); // 2 Mb
			

			try {
			

			FileItemIterator iter = upload.getItemIterator(request);
			

			while (iter.hasNext()) {
			

			FileItemStream item = iter.next();
			

			if (!item.isFormField()) {
			

			File tempFile = saveFile(item);
			

			// process the file
			

			}
			

			}
			

			}
			

			catch (FileUploadException e) {
			

			LOG.debug("Error uploading file", e);
			

			}
			

			catch (IOException e) {
			

			LOG.debug("Error uploading file", e);
			

			}
			

			}
			

			

			private File saveFile(FileItemStream item) {
			

			

			InputStream in = null;
			

			OutputStream out = null;
			

			try {
			

			in = item.openStream();
			

			File tmpFile = File.createTempFile("tmp_upload", null);
			

			tmpFile.deleteOnExit();
			

			out = new FileOutputStream(tmpFile);
			

			long bytes = 0;
			

			byte[] buf = new byte[1024];
			

			int len;
			

			while ((len = in.read(buf)) > 0) {
			

			out.write(buf, 0, len);
			

			bytes += len;
			

			}
			

			LOG.debug(String.format("Saved %s bytes to %s ", bytes, tmpFile.getCanonicalPath()));
			

			return tmpFile;
			

			}
			

			catch (IOException e) {
			

			

			LOG.debug("Could not save file", e);
			

			Throwable cause = e.getCause();
			

			if (cause instanceof FileSizeLimitExceededException) {
			

			LOG.debug("File too large", e);
			

			}
			

			else {
			

			LOG.debug("Technical error", e);
			

			}
			

			return null;
			

			}
			

			finally {
			

			try {
			

			if (in != null) {
			

			in.close();
			

			}
			

			if (out != null) {
			

			out.close();
			

			}
			

			}
			

			catch (IOException e) {
			

			LOG.debug("Could not close stream", e);
			

			}
			

			}
			

		

I am new to that kind of things and I cant really find whats going wrong!

Thanks for your time.
